SELF REPAIRING TECHNOLOGY IN SMARTPHONES

WOULD  YOU  LIKE IT IF  YOUR  GADGETS  COULD JUST HEAL LIKE WOLVERINE 

When a smartphone or a laptop is dropped from someone’s hands, one of the universally felt emotions is that of severe anguish. Several questions immediately pop into the head - did the screen break? Is it working? How much is this going to cost? Will my new phone have scratches and dents now? In fact, Motorola based an entire smartphone’s design to tackle this in the Moto X Force by implementing a shatter proof screen. But is sheer brute strength all that can be done to make gadgets, or at least parts of gadgets, damage proof? Self repairing technology is not an entirely new scientific breakthrough right now. Actually, if you have been delving around smartphones and following technology updates for more than a year or two now, this cannot be the first time you are hearing about self repairing tech. But it is about time that this breakthrough escapes the labs and enters mainstream store shelves. Let us explore what it is all about and how close we are to damage proof gadgets that can at least give themselves first aid after an accident

What does it actually mean?


Before we begin, let us clarify that self repairing tech does not imply T-1000 level healing, where your broken dismembered gadgets gather themselves together and somehow become one again. Nor does it cover intelligent robots that can put themselves together. What self repairing tech in its current state of the art does is mostly surface repair, which highly depends on what material the gadget’s surface is made out of. Any material stops working the way it is supposed to due to three factors • Decay - Over time, factors like light, heat, micro organisms, cause certain material to outlive their usability sooner than they would unaffected. • Fatigue - Physical usage factors like friction and wear-tear • Defects - Under suddenly applied force and stress, some materials show cracks and fractures, or holes that spread very rapidly. The first two factors are actually  unavoidable for most material and can be comparatively easier to spot. It is the third one that is the most dangerous and can even form internally. Although there are techniques to test for these without destroying the material, like ultrasound scanning, most of these defects happen during actual usage where such testing is not being done. This is where the inspiration from our very own human body comes into play. The human body can actively sense damage, stop it from worsening and start working on fixing it in real time. It is this phenomenon that self-healing materials aim to replicate, without human intervention in the repair process


How does it work? 

Almost all the things that we see around us nowadays are made out of plastics, or as science likes to call it, polymers - smartphones, shoes, bottles, footballs, houses etc. So it is not unexpected that research into self-repairing materials is mainly focused on polymers. This research has been mainly ongoing since early 2000s and one of the first breakthroughs was achieved by the team of Scott White, Nancy Sottos, and their colleagues from the University of Illinois at Urbana Champaign.


Embedded Healing Agents 

The most approachable self-healing technology involves micro-capsules of adhesive substance embedded into materials. When the material cracks or is under stress, these capsules break open and the adhesive material, or glue, comes out to fill the cracks and solidify. This glue can be simply a strong adhesive that holds the material together. In another approach, where the material itself is mainly a solid polymer, this glue-like material is a liquid made of the corresponding monomer (the basic constituent of the polymer). Now, when the material cracks, the capsules break open, and the polymer is exposed to the monomer resulting in further polymerization that creates more of the original polymer which fills the damaged area. Typically, this process might need a powdered chemical catalyst to be included for it to successfully occur at normal temperature and conditions without intervention. The main problem with this approach is that the embedding might structurally weaken the original material. Due to that reason, there is a size restriction on the capsules. Also, this is a one-time method, because once the capsules are cracked, another instance of damage at the same location will have nothing to rely on. And that second instance is highly likely due to the weakening of the material after repair. Also, since microcapsules have to be below a certain size threshold, there is a very strict limit to the size of cracks that can be filled. 

Microvascular Healing


Taking the human body analogy one step further, microvascular healing technology implements micro-tube like structures within the material that connect to a pressurised source of adhesive material. Wherever a crack occurs in the material, the tube is depressurized at that end and the material flows into the crack. This method can seal cracks up to ten times the size that can be fixed by micro-capsules. This method has its own drawbacks as well, since some cracks will spread faster than they can be repaired. But on long term cracks, like those that appear on pavements and buildings, this method is certainly useful.


Memory Materials

There is a particular classification of materials that has a tendency to remember and retain its original shape. Don’t worry, there is no actual memory involved here and your favorite shoe is not suddenly going to become sentient. Memory materials are all around us, like the frames of the eyeglasses that we wear, which snap back to their original shape even if we bend them. Some of these materials require an external influence like heat or light to repair themselves. This can be achieved by a network of fibre-optic cables similar to the microvascular network described in the previous method. But this network would  bring heat and light to the point of damage, causing the material to alter back to its original configuration. In fact, it has the added advantage of making the material fibre-reinforced.

                           Self Repairable concrete can extend the durability of construction significantly!


So what’s really out there already? 

Although it is true that full scale self repair technology is not even present in the labs as of now, there have been a lot of interesting developments in that direction that show a lot of promise. When Hendrik Jonkers, Microbiologist at Delft University, was looking for a way to strengthen concrete, he didn’t turn towards the conventional methods of steel or stone reinforcement. Rather, he took inspiration from his own domain of biology. His solution involves using limestone-producing bacteria in the mixture for concrete, which can close up the gaps eventually. While the concrete is being mixed, specially selected types of bacteria along with nitrogen, phosphorus and calcium lactate are added as ingredients. These constituents can stay dormant in the concrete for upto 200 years.Whenever a crack shows up on the surface, the bacteria is activated by air and it starts reacting with the calcium lactate and oxygen to produce insoluble limestone that fills up the cracks. This method can deal with cracks up to almost a centimetre in width.

In 2013, LG had announced LG Flex which, apart from being one of the few phones in the market with a curved display, was also the only one with a back that could heal itself from minor scratches. This was no marketing gimmick as tech enthusiast Marques Brownlee demonstrated the back of the phone healing from scratches made with keys. Although there have been several speculations and guesses regarding this technology, LG has so far refused to reveal how it works. The most accurate guess seems to be related to Hydrogen bonds and their affinity to stay together. It should be noted that this will not work if the scratch is deep enough to remove the material itself. Also, Apple has indicated that they are currently working on self healing technology to make iPhones that can repair themselves. So, while it is true that self-repair technology for smartphone screens and bodies are already possible, they are still too expensive or impractical for mass production. In development since 2012, it was only last year when Professor Duncan Wass and his team announced the development of material for aircraft wings that can repair itself after suffering damage. This works on the microsphere embedding principle and also involves a catalyst that speeds up the chemical reaction involved. It was found that the material was as strong after the reaction as it was before the damage. Professor Wass’ team has been focussing on developing carbon-fibre material with this technology as it has massive applications in the fields of automobile, aviation, sports equipments and a lot more. For example, offshore wind turbines, that often get damaged due to bird strikes, could self repair and not require extensive maintenance any longer.

Uncountable lives can be saved if aeroplanes could have self-repair wings

The Future

It is no breaking news that we need to rapidly shift over to sustainable methods of manufacture and consumption to ensure that we even have a future worth living in. On that note, the importance of self repairing tech is obvious. If less concrete needs to be produced due to a kind that repairs itself, there will be fewer factories manufacturing concrete in polluting and unsustainable ways. If fewer smartphones need to be replaced every year, fewer factories in third world countries will ignore basic human rights and living conditions to produce cheaper smartphones by the millions to satisfy the current demand. This technology truly holds the key to a sustainable world that spends less on replacing and fixing itself, produces a lower carbon footprint and thus lets itself exist way longer into the future

ANDROID 7.0 NOUGAT - Marshmallow successor

While some of us may have seen large parts of Nougat already, we’ll be approaching this Android 7.0 review from the perspective of a new user – someone who hasn’t “seen it all before”. We want to provide a sweeping overview of Android 7.0 features, but we’ll also draw comparisons to Marshmallow where relevant and provide context with discussion of features that appeared in the pre-release versions of Android N but that didn’t quite make it to the final version.

If I had to sum Android Nougat up in a nutshell, I’d say that it’s Android putting its roots down. The general feel of Android has become increasingly stable since Lollipop, with less feature flip flopping, fewer performance issues and a greater focus on polish. Nougat is all about extending functionality, improving pre-existing features and further expanding what’s possible in stock Android.

As you know, Marshmallow largely maintained the overall look of Lollipop but baked in some big new features like Doze Mode, the fingerprint API and granular permissions. One year on and Nougat follows suit, maintaining the home screen and app drawer design of Marshmallow, but digging even deeper, laying the fundamental groundwork for what is yet to come.

There are some new visual features to be sure, with a redesigned Settings menu and notifications area. But there’s also a lot more enhanced functionality and exciting background stuff going on in Nougat than you see on the surface.

Split-screen mode: how it works

Nougat finally delivers split-screen mode to stock Android, a feature that has been around in manufacturer skins and custom ROMs since forever. Android Nougat’s built-in version is in some ways better than what we’ve seen before, but it can also be a little… over the top. Now, take a deep breath as I walk you through how it all works.

Split-screen works in both portrait and landscape mode, with the two ‘windows’ only being resizable in portrait mode. App developers can set their own minimum app height, but in landscape mode you’re stuck with a 50/50 width split, which actually makes sense.

Split-screen mode can be activated by long-pressing the app overview/recent apps button while in an app proper. It can also be activated by long-pressing an app preview card in the app picker and dragging it to the top of the screen. You can even enable a gesture action so it launches when you swipe up on the overview button. So far, so many options.

That first app will then appear in the top window (or on the left if you’re in landscape mode) and you’ll be able to choose your second app from the app picker which displays automatically. Or, when the app picker is displayed in the secondary window, you can tap Home to launch an app from your home screen or open the app drawer.

Think of it like this: the app up top (or on the left in landscape mode) is the primary app, the other app is secondary and it is the one that can be changed easily. With this in mind, you’ll always want to start multi-window mode with the app you’re less likely to want to change.

Quick switching apps

Quick switching is basically just shuffling between the two most recently used apps. It works system-wide, so you can quick switch whenever you’re in a full-screen app and you can also use it in the secondary window of split-screen mode.

Simply double tap the app overview button and you’ll switch between your two most recent apps in your secondary window. (The same gesture flips between full-screen apps when not in split-screen mode.)

The presence of the quick switching action – possibly my favorite Nougat feature of all – thus means you can triple task in multi-window mode. For example, you can be watching a YouTube video in the top window and quick switch between two social feeds in the bottom. Or you can be composing an email in the top pane while simultaneously switching between a note app and a web page in the bottom window. It’s actually pretty awesome

Working with split-screen mode

Speaking of writing, multi-window mode is pretty smart when it comes to the keyboard. If you have two evenly-spaced windows up and need to type into one (say, a URL or search term), the windows will automatically resize to accommodate the keyboard and then automatically switch back when the keyboard is off screen again. You can also cleanly drag and drop text between the two windows although this doesn’t work with every app.

Exiting split-screen mode is quite intuitive also: just drag the black divider all the way up to go full screen with the app on the bottom or drag all the way down for the app on the top. Alternatively, you can long-press the app overview button again and your primary app will go full screen.

Hitting the Home button while in split screen mode pushes your apps off screen but you’ll always know you’ve got split-screen mode activated because your status bar will retain the color of the primary app and the overview button will change to a split-screen icon. Double tapping the overview button will return you to your current split-screen setup while tapping it once will bring back your primary app and replace the secondary app with the app picker.

BETTER

Not everything in Nougat is so convoluted though. Some features are plain, simple and intuitive. From new feature additions to tweaks on Marshmallow staples, Nougat does a lot of things better than its predecessor.

Notifications: redesigned, bundled and Quick Reply-able

The notifications area in Nougat has received a slight makeover, doing away with the Google Now-esque cards from Marshmallow and going super flat and full-width. You get more information and less wasted space in them too, which is exactly what you want from a notification. Likewise, bundled notifications and Quick Reply are so obvious and so useful it’s surprising they haven’t appeared in stock Android until now.

There are basically three views to Nougat notifications: the super-compact lock screen view, the slightly-more-information notifications shade view, and the expanded view with ‘quick actions’, which you access by swiping down on a notification or by tapping the top part of the notification itself. Quick actions are what I’m calling Nougat’s sexy new Quick Reply feature and other similar functions.

Quick Reply is simply the ability to reply to a message directly from its notification without having to open the app fully. It’s a fantastic feature and one that will save you a lot of time and endless app switching.

But quick actions go beyond just replying: you can also share, delete, archive and more directly from a notification. These actions make Nougat’s notifications area a much more active and responsive place. But again, not all apps support this functionality yet either.

Notification prioritization

You can still swipe to dismiss notifications and tell Android how much notification information to display on the lock screen in the Notifications area of the Settings (Sounds also has its own dedicated section in Nougat). But you can also long-press a notification to access its priority settings or swipe it a little to the side and tap the gear icon to access your options.

The choices are simple: show notifications silently; block all notifications; don’t silence or block. You can also enter the full app settings page where you have even more control, including whitelisting the app to notify you even when Do Not Disturb mode is on (but more on that later).

Multiple notifications from the same app will now get bundled together too, saving more space and allowing you to dismiss them en masse or expand them for individual attention.

System UI Tuner is back

For those of you that preferred the ‘sliding scale’ for setting the importance of app notifications from the developer previews, you can easily enable it in System UI Tuner via Power notification controls.

To add System UI Tuner to your Settings menu, just tap and hold the gear icon in the Quick Settings until it spins and your device vibrates. You’ll now find it at the bottom of the Settings menu. System UI Tuner also contains the toggle for the split-screen swipe-up gesture and toggles for which icons are visible in the status bar. You also find some Do Not Disturb options there.

Customizable Quick Settings

Quick Settings in Nougat have also been updated. For starters, you’ll now always have a handy list of five toggles at the top of your notifications shade. You can edit the order of this list to make sure only the most important shortcuts for you are present. The small arrow on the right hand side will take you to the full Quick Settings page, which you can also access with the familiar two-finger swipe-down gesture from the top of the screen.

You can now have multiple pages of tiles too. Some of them instantly toggle a setting on or off, like the flashlight, Do Not Disturb mode and Location. Other tiles, like Bluetooth and Wi-Fi, can be tapped to access a mini menu right in the Quick Settings.

The ability to turn Bluetooth and Wi-Fi off must now be done from the mini-menu, even after the uproar about removing the tap-to-toggle functionality in the developer previews. Fortunately though, you can toggle Wi-Fi and Bluetooth on or off via the ever-present Quick Settings toggles at the top of the notifications shade. Long-pressing a tile will take you to its full Settings menu screen.

In the full Quick Settings list you can also tap the Edit button at the bottom right to rearrange the tiles or replace them with others. The optional extras list is pretty minimal: just Cast, Data Saver, Invert colors and Hotspot. But developers are now able to create custom Quick Settings tiles for their apps, which will definitely make things a lot more interesting in the coming months.

Doze Mode on the Go

Some of you might remember how happy I was when the battery shortcut appeared in the developer previews, which meant a long-press on the battery icon would instantly take you to the full battery section in Settings. That’s here and I’m happy. But that’s not the most exciting battery feature in Nougat by a long shot.

Doze Mode has now been beefed up to work not only when the device is stationary for a while but also when it is in motion. Your screen needs to be off, obviously, but you’ll now get to enjoy varying degrees of Doze whenever your phone isn’t being used. It’s a little too early to say just how much better Doze is in Nougat, but the expanded functionality alone is appreciated.

The new two-layer system essentially means that a phone left in your pocket or bag while you’re on the move will shut down network access and only periodically sync data and run tasks. When a device is completely stationary for a while, it will slip into an even deeper hibernation, with no syncing, deferred jobs, no wakelocks and no GPS or Wi-Fi scanning. In this mode, the maintenance windows are even further spread out.

FASTER

Android Nougat isn’t just about making things better or more complex though. A lot of work has been put into speeding Android up, a far greater project you can see Google-wide, from Chrome optimization and Accelerated Mobile Pages to Google Fiber and the Wing drone delivery project.

New Settings menu

The Settings menu has been reconfigured in Android 7.0, with the two primary changes being the addition of a hamburger menu on the left and the presence of high-order information under each Settings section title. The first of these is going to be very familiar: it’s the same mechanism you’re used to for accessing Google Now and the navigation drawer in many Google apps.

Although you can access it anytime, once you’re in a sub-menu in Settings you’ll see the hamburger menu icon at the top left, which replaces the need for the back button. Tap it (or swipe from the left edge) and you can jump to any other part of the Settings menu instantly without having to repeatedly tap the back arrow.

Even when you can’t see the icon, like in the Advanced Wi-Fi Settings or on the main Settings page, you can still swipe it out. It’s a handy ‘quick escape’ feature even if it’s not likely to be used by many people. Like a lot of new features in Android 7.0 you can use it if you want to, but if not, you won’t even notice it’s there.

The best part of the new Settings menu though is that the essential information contained in each Settings section is now displayed right there on the main page. You’ll instantly know which Wi-Fi network or Bluetooth device you’re connected to, how many apps you have installed, how much storage you’ve used and how much longer your battery is expected to last. It’s a small addition perhaps, but another massive time saver.

There’s a new Suggestions area at the top of the Settings menu, where you’ll intermittently see suggestions from the Android system about a variety of things. From reminding you to use voice search, register a fingerprint, add email accounts or change your wallpaper, you can act on them or minimize and ignore them at will. If you want to get rid of the section entirely, just tap the overflow menu and remove all Suggestions.

When you’ve got Do Not Disturb mode (or several other settings like Flight Mode) enabled, you’ll also see a persistent reminder at the top of your Settings menu where you can also turn it off. The built-in file manager – found in Storage > Explore – has been slightly rejigged too, using a tiled layout now instead of the list view you got in Marshmallow.

In Nougat, when you go to the App Info page for apps you’ve installed yourself you’ll now be able to see whether they came from Google Play or were side-loaded. This probably won’t matter to most folks, but it will help if you’re wondering why an app hasn’t been updated recently or if you’re troubleshooting something.

Sounds and Notifications now have their own dedicated Settings areas and you can set your phone to Total Silence via the Do Not Disturb toggle in Quick Settings (but not via the volume button).

Do Not Disturb

Do Not Disturb has been one of the most complicated implementations of any Android feature in recent memory. If nothing else, continued exposure to it means the basic idea has probably slowly started to sink in by now though. If you can wrap your head around it, it can actually save you a lot of time and effort when you don’t want to be interrupted.

The Do Not Disturb settings allow you to choose from Total Silence, Alarms Only and Priority Only. You can set exceptions for Priority Only mode to allow certain notifications in, enable Do Not Disturb mode for a set period of time or indefinitely, create automatic rules for the weekend, evenings or work hours and also block visual disturbances like LED notifications or on-screen pop-ups.

Seamless updates

Speaking of updates, Android Nougat is also introducing the concept ofseamless updates, which essentially means new Android updates will be downloaded in the background and stored on a different system partition. It’s the same approach to upgrading that Chromebooks take.

Once an update has been downloaded in the background, the next time you restart your phone, the system will switch partitions and you’ll instantly have the new Android updates without having to go through the usual download, reboot and install process.

Unfortunately, the 2016 Nexuses will be the first devices to receive these seamless updates though. That means you won’t get them on any current device, including the Nexus 6P and Nexus 5X.

Maintenance updates and the beta program

For those of you on the Android N beta program, you might want to stay on it even now that Nougat is officially out. Google has announced that regular Maintenance Release (MR) updates will be rolling out in pre-release form to those on the beta program. The pre-release MRs will bring “continued refinements and polish,” but also deliver bug fixes and feature tweaks before everyone else gets them.

As with all beta releases though, these might also be less stable than the regular updates everyone else will get. If you’re the type that simply must have the latest and greatest as soon as possible and are willing to suffer the occasional bug to get them, then the beta program is for you. Everyone else can just sit tight and wait for the regular public releases to roll out.

Camera shortcuts

The update to the Google Camera that comes with Nougat on Nexus devices also adds a new twist gesture to switch between front and back cameras. Unlike on Moto devices, it can’t be used to launch the camera so it only works when the camera app is already open.

Fortunately, the outstandingly handy power button shortcut returns, so all you need to do to instantly launch the camera is double press the power button. You may need to enable this feature in the Display settings first though.

STRONGER

No Android update would be complete without security improvements either. Android 7.0 has a lot of stuff going on, from hardening the media stack so as to deny future Stagefright-style media library privilege escalations, to simply letting you know from where an app was installed. But Nougat also has a few safety-minded features as well as serious security advancements.

WRAP UP

If you’ve made it this far then you’ll be painfully aware of just how few sexy and exciting “general audience” features Android Nougat has and just how many boring but ultimately more-useful-for-everyone nerd-features it packs in instead. There is a lot of customization potential in stock Android now, more than there has ever been before, but it is perhaps wisely kept out of mainstream view.

Nougat adds some great features, the kind of stuff we used to have to turn to custom ROMs, manufacturer skins or third-party apps to get. But most of these will only really ever be used by advanced users – either because they are too complicated for the ‘average user’ or because most people will never even realize they even exist.

This is perhaps, the best way to sum up Android 7.0 Nougat. It’s an Android version for Android fans. It does the basics well and without much fuss for everyone, but for those of us willing to dig around or with an eye on the future, there’s plenty to keep us busy. It’s remarkably stable with only a few inconsistencies and bugs: certainly the fewest I’ve ever seen on a new Android version.

But while it may be harder, better, faster, stronger for the Nexus master race, for the vast majority of Android users, the most important Nougat feature will be how well it works if or when they ever actually get it on their device.

kIRIN CHIPSETS - "DARE TO PERFORM"

Huawei's brand new Kirin chip set have already entered the indian market with their flagship smartphone series honour.  Right from the 16nm manufacturing process to the improved architecture, latest graphics engine and support for next-gen wireless connectivity and LTE networks these chipsets are launched  by  company to provide tough fight to MediaTek and Qualcomm that happen to be two of the biggest players in the mobile SoC space, and have been vying to win market share in markets worldwide.

 With tagline of " DARE TO PERFORM"   lets see  how does the Kirin 650 compare to the current generation of SoCs from Qualcomm and Mediatek?

Faster, cooler and a power efficient chip: All- new Kirin 650 chipset with flagship FinFET Plus 16 nm chip technology offers lightning-fast performance compared with previous-generation 28 nm chipsets

Optimized big.LITTLE Architecture:  Huawei Kirin 650 delivers best of both worlds in terms of performance and efficiency. Four 2.0 GHz high-performance cores, and four 1.7 GHz lower-performance cores work their magic by approaching tasks in the most optimized manner. Lighter tasks are assigned to lower clocked cores, ensuring maximum power efficiency along with speed. While heavy tasks are handled by the high 

performance cores, ensuring power-on-tap for demanding tasks like gaming, rendering, etc

The Mali 830 GPU on the Kirin 650 SoC offers comprehensive support for current and next generation APIs, enabling advanced 3D graphics acceleration and GPU Compute functionality. This includes support for the Khronos OpenGL ES 3.2*, 3.1/2.0/1.1, Vulkan 1.0* and OpenCL 1.1/1.2* Full Profile APIs. Additionally support is provided for the Android Extension Pack, Android Renderscript  and Microsoft Windows DirectX11 FL9_3.

Power efficiency: Built on advanced 16nm manufacturing process, Kirin 650 allows for multiple reductions in energy loss while being able to push the clock speed of the cores higher. The Kirin 650 also comes with silicon-chip level protection. There is a dedicated security module within the silicon chip that ensures user security, handling key information like fingerprints, keypad, and voice.

The 16nm FinFET advantage: 16 nm FinFET technology is a flagship class manufacturing process usually reserved for top level SoCs, the Apple A9 and Kirin 950 use 16nm FinFET manufacturing process. Kirin 650 is the only SoC among the competing midrange SoC that uses 16nm FinFET technology.  Among mid-range silicon chips, Qualcom's Snapdragon 650 and 652 processors continue to use 28 nm technology, while MediaTek's SoC fall in the 20 to 28 nm. The Kirin 650, although positioned as a mid-range SOC, actually employs 16 nm FinFET Plus technology, making it two generations ahead of the competition due to its greatly improved performance and reduced power consumption.

Superior Network Reception: Flagship-grade dual antennas system support on the Kirin 650 SoC automatically switches to the antenna with the best signal to prevent dropped calls.

  To know actual and real performances of any phone or chipset its the best  to compare them using benchmark test .

Snapdragon 616 octa-core processor alongside MediaTek MT6752 and Kirin 620 are the mid-range processors in the market. All three mobile processors are octa-core processor and support 64-bit capabilities. Well. Let’s take a look at the benchmark scores comparison between Snapdragon 616/615,and Hisilicon’s Kirin 620.

CPU Performance

Vellamo 2 Metal measures the CPU subsystem performance of mobile processors. Metal 3 is the latest version of Vellamo’s CPU benchmark. Geekbench 3.0 is Primate Labs cross-platform processor benchmark which simulates real-world scenarios and gives a combined score, based on the results of integer, floating point and memory performance.

Qualcomm Snapdragon 615 (Alcatel OneTouch Idol 3)       801                         1066                   2006

HiSilicon Kirin 620 (Huawei P8lite)                                     765 (-4%)           1076 (+1%)     2805(+40%)                                                                                            

.we  will  conclude our tests with a tough pi (π) calculation of the first 10 million digits of the mathematical constant. This is a good indicator of the raw CPU performance of all cores. The Kirin 620 chip has an advantage here, completing the calculation in 39.709 seconds. Qualcomm Snapdragon 615 managed to do that in 45.095 seconds, or 14% slower.Pi (π) calculation

The Chinese smartphone maker has come a long way as a chip maker, and we think the latest release from them is a showcase of their ability to produce fast, efficient and reliable chipsets. Moreover, it also allows them to optimize their handsets uniquely based on their in-house chipsets

Screenshots are a great way to capture whatever is on your screen and store it for later use. Sometimes you need to capture a screenshot to remember a password or capture some other pertinent information that you can’t save otherwise.

Other times you need to capture a screenshot and send it to someone else so that they can help you or see what you were doing. Finally, you may want to capture multiple screenshots over a certain time period so that you can see the activity occurring on the computer.

In this article, I’m going to show you how to use a free program to automatically capture screenshots of your computer screen at specified time intervals.

Auto Screen Capture

Auto Screen Capture is an open source utility on SourceForge that has quite a few options for capturing screenshots on your Windows machine. The program works with Windows Vista and higher, including Windows 10.

The good thing about the program is that it doesn’t even require you to install it. All you have to do is download the exe file and run it. This is great because it doesn’t add anything to your registry or copy files into your system directories.

When you run the program, you’ll see the main interface is split up into a couple of different sections. At the top left is a calendar and below that are the main settings for the program. On the right-hand side, you have previews of each screen connected to your computer. If you only have one monitor, you’ll only see the preview for Screen 1.

By default, the program is set to Demo Mode ON and Schedule Off. This means that when you open the program, the main interface will show up so that you can configure the options. The first thing we want to do is change these settings. Click on the Options button at the very bottom left and then click on Turn on demo mode at application startup to uncheck it. Click on Turn on scheduled screen capturing at application startup to check that option.

The rest of the options are self-explanatory. If you are trying to capture screenshots stealthy, it’s a good idea to uncheck Open this window at application startup, Open this window after stopping the running screen capture session, and Show the slideshow after stopping the running screen capture session. You can also store the screenshots on any drive connected to the computer, including network drives. This is great if you want to install the program on several computers and have all the screenshots saved directly to a server, NAS, etc.

On the Screen Capture tab, the top section controls how often the screenshots will be taken. By default, the program is set to take a screenshot every second, which is a bit ridiculous. If you don’t want all the space on your computer gone in two days, change the timings to something more reasonable like every 30 seconds or every 2 minutes. I would keep Initial capture checked as that includes an additional screenshot of the active window.

The program will create two folders for each day, one with a screenshot of the full desktop and one with a close up of wherever the mouse is located at the time of the screenshot. This is a cool little feature that lets you see the screen in more detail only for the active section of the screen.

Also by default, the program is set to stop after 30 minutes, so if you want screenshots taken continuously or for a longer time, either uncheck the Limit box or type in a higher value. Finally, the Resolution box is set to 100% by default, but you can adjust this setting if the files are too big.

If you scroll down, you’ll see you can also set a schedule for taking screenshots. If you want the program to automatically start taking screenshots, rather than you having to manually start the capture process, check the Start capture at and Stop capture at boxes. Screenshots will only be taken during that time period at the time interval you specified above.

Finally, if you scroll down a little more, you can change the image type to something other than PNG. You can choose from BMP, EMF, GIF, JPEG, TIFF and WMF. In my opinion, the best option is JPEG as it will give you the best quality with the smallest size. In my tests, a full desktop screenshot at 2560×1440 was about 160 KB. If I used the PNG format, the same screenshot was a whopping 1.7 MB!

Click the Start Capture button to start the capturing process. The program should disappear into the taskbar, where it will remain while taking the screenshots. Unfortunately, the best thing you can do to hide it is put it inside the overflow section in the notification area.

This program wasn’t created with any kind of stealth mode or anything like that, so if you need discreet screen recording software, this might not work for you. Once some screenshots have been taken, you can easily view them by going to the Slideshow tab.

If you don’t want to view the screenshots in the program, you can also just browse through the folder using Explorer. In my case, the top level folder was the date and then inside I had a folder named 1 and a folder named 5. One contained full-desktop screenshots and the other contained close-ups.

It’s also worth noting that if you are using Windows 10 with multiple virtual desktops, the program will capture a screenshot of only the active desktop at that time. So if the user switches to desktop 3, you’ll get a screenshot of desktop 3. If they switch back to desktop 2, then you’ll get that desktop in the next screenshot.

Finally, if you click on the Keylogger tab, you can set the program to record all keystrokes while the program is running. Just check the Enable keylogging while screen capturing box. The file will be stored in the same location as the screenshots.

The keylogger is pretty nice in the sense that it actually lists out the program where the keystrokes were recorded. This helps you make sense of all the text in the document.

Overall, the program works really well, considering it’s free of charge. It only works on Windows, but that should be fine for most people. If you need screenshots at set time intervals, this is the best program for the job. Enjoy!
