Hopefully you are already well aware that a large number of free Android apps slurp up a lot of personal information about you, however you might not realize the extent of the issue. Researchers have just released a report which documents the amount of personal data that popular apps such as Uber, Tinder, Skype, Twitter, Spotify, and Snapchat gather about you, which The Inquirer linked to. These apps collect and then share your name, phone number, e-mail address, login, IP address and device ID with targeted advertisers, something that many of the apps do not make clear when you install or use them. That data can be used for some rather interesting things, such as tracking the physical location of your phone, so the next time you are installing an app on an mobile phone of any flavour you might want to consider what it may be sharing especially in light of the recently revealed Uber hack.
"In case you're wondering, yes, there's a good chance at least some of your Android apps have tracked you rather more than you expect."

Huawei has announced the successor(s) to the Mate 9 smartphone with the new Mate 10 and Mate 10 Pro, which feature a new "3D Glass Body" industrial design along with the new Kirin 970 processor and other improvements.
The key features from Huawei include:
- Kirin 970, the world’s first AI processor for smartphones with a dedicated Neural Network Processing Unit (NPU)
- A 3D Glass Body featuring a barely-there-bezel, HUAWEI FullView Display and HDR10 supported technology for intensely vivid and brighter colors
- TÜV Fast-Charge Safety Certified HUAWEI SuperCharge and 4000 mAh battery with AI-powered Battery Management
- New Leica Dual Camera with SUMMILUX-H lenses, with both featuring an aperture of f/1.6, and intelligent photography including AI-powered Real-Time Scene and Object Recognition and AI-powered Bokeh Effect;
- An all-new, simplified EMUI 8.0 based on Android 8.0
The Mate 10 Pro features an 18:9 OLED display
The Mate 10 is a 5.9-inch device with a 16:9 IPS display supporting HDR10, while the Mate 10 Pro offers an 18:9 OLED display (also with HDR10 support).
The new dual-camera system is again a joint effort with Leica, and combines a 12 MP color sensor with a 20 MP monochrome sensor, using lenses with a aperture of f/1.6 - and Huawei says this aperture is the "world's largest" for a smartphone. The digital zoom and bokeh effects are AI-powered, along with real-time scene and object recognition.
The new Kirin 970 combines an 8-core CPU with a 12-core Mali-G72 GPU, and includes an NPU (neural processing unit) for AI-related tasks as well as a new dual ISP for the AI-powered camera features mentioned above.
Both phones include a 4000 mAh battery which offers "smart battery management" which Huawei states "understands user behavior and intelligently allocates resources to maximize battery life". The new TÜV-certified fast charging feature supports low-voltage charging of 4.5V / 5A, and Huawei states this will charge the phones from 1% to 20% in 10 minutes, or 1% to 58% in 30 minutes.
The Mate 10 lineup
The Mate 10 and Mate 10 Pro ship with Android 8.0 and a new "simplified" version of Huawei's EMUI interface. Pricing and availablity for the U.S. was not revealed, but the phones will go on sale internationally starting this month for the Mate 10, and mid-November for the Mate 10 Pro.
The Mate 10 Pro lineup
While we don't have U.S. pricing yet, European pricing for the Mate 10 with 64GB of storage and 4GB memory is set at €699, and the Mate 10 Pro with 128GB/6GB will be €799.

Microsoft is adding an Edge-y experience to mobile devices not running the rarely seen Windows Mobile. Android users who never heard of Arrow will now not know it as Microsoft Launcher; those who try will find a Chromium based browser which resembles Edge and knows a few of its tricks. iOS users will be running Safari WebKit wrapped all the way to the Edge of their screens. In both cases Edge will offer the same cross-system abilities as it does on PC, allowing you to immediately resume reading a document and sync apps from or to your mobile device. That functionality does have prerequisites, you would need to be using a PC running Windows as one of your devices and it has to have the Fall Creators Update installed, which hasn't yet been pushed out. If you haven't yet fallen asleep, you can continue on Ars Technica.
"As with Edge, the important part of the Launcher is the cross-device experience. Documents and photos has a "continue on PC" option that will open them up on a computer, making it easier to start working on the phone and then resume on a computer."

The midrange phone market has a new contendor with the ZenFone 4 Max, launched today by ASUS and featuring some impressive specifications - particularly in the camera department - for an unlocked device with an MSRP of $199.
The phone offers a 5.5-inch display - though likely due to the price target it is just 1280x720 - and the metal and glass construction gives it a more premium (if familiar) look. It's the back of the device where the dual camera sensors really set this apart from the majority of ~$200 unlocked phones: a pair of 13 MP sensors reside behind both a wide-angle and telephoto lens, which allows for more flexibility in composing shots.
"ZenFone 4 Max features an advanced dual-camera system designed to take your mobile photography to new heights. Its 13MP main camera is equipped with the wide, F2.0 aperture lens to capture clearer photos. Its 120° wide-angle camera lets your fit more scenery and people in the frame for dramatic landscape shots, better group photos, and a more convenient photography experience in confined indoor spaces."
The application processor is the Snapdragon 430, a capable 8-core design with Adreno 505 graphics which also crucially offers 2x image signal processors for a dual camera setup. One area that is decidedly not midrange is the battery - which is a whopping 5000 mAh (!). Not only does this massive capacity allow for the unusual feature of turning your smartphone into a battery pack to charge other devices, but it should provide some really outstanding real-world battery life as well. The onboard Snapdragon 430 supports Qualcomm Quick Charge 3.0, so refilling that huge battery should be efficient as well.
The unlocked ZenFone 4 Max is available now for $199 on Amazon.com in a 32GB capacity.

Can you imagine a world in which you're able to share links between your phone and computer? This is the brave new frontier which Microsoft is exploring in Version 16251 of Win10 which will allow you to link to an Android phone via a app for Android on the Windows Store. Mind you there are a variety of programs out there which already fulfill this purpose, The Inquirer offers an example here, and if you sign into Chrome it will happily sync itself on all your devices.
On the other hand this is a first step towards admitting that Windows Mobile is not the success they had dreamed. Microsoft does see this as a much a larger project and taking the initial steps slowly could help in the long run; as long as they can get people to notice what they are doing and attract at least some attention.
"But it does lay foundations, and it does show intentions. It's hugely unlikely that Windows Mobile is ever going to claw its way back to the levels to compete with iOS and Android, so it is important that as it approaches its second birthday, Windows-as-a-Service is approachable from other mobile operating systems."

Introduction and Specifications
The Galaxy S8 Plus is Samsung's first ‘big’ phone since the Note7 fiasco, and just looking at it the design and engineering process seems to have paid off. Simply put, the GS8/GS8+ might just be the most striking handheld devices ever made. The U.S. version sports the newest and fastest Qualcomm platform with the Snapdragon 835, and the international version of the handset uses Samsung’s Exynos 8895 Octa SoC. We have the former on hand, and it was this MSM8998-powered version of the 6.2-inch GS8+ that I spent some quality time with over the past two weeks.
There is more to a phone than its looks, and even in that department the Galaxy S8+ raises questions about durability with that large, curved glass screen. With the front and back panels wrapping around as they do the phone has a very slim, elegant look that feels fantastic in hand. And while one drop could easily ruin your day with any smartphone, this design is particularly unforgiving - and screen replacement costs with these new S8 phones are particularly high due to the difficulty in repairing the screen, and need to replace the AMOLED display along with the laminated glass.
Forgetting the fragility for a moment and just embracing the case-free lifestyle I was so tempted to adopt, lest I change the best in-hand feel I've had from a handset (and I didn't want to hide its knockout design, either), I got down to actually objectively assessing the phone's performance. This is the first production phone we have had on hand with the new Snapdragon 835 platform, and we will be able to draw some definitive performance conclusions compared to SoCs in other shipping phones.

Introduction and Design
In case you have not heard by now, Pixel is the re-imagining of the Nexus phone concept by Google; a fully stock version of the Android experience on custom, Google-authorized hardware - and with the promise of the latest OS updates as they are released. So how does the hardware stack up? We are late into the life of the Pixel by now, and this is more of a long-term review as I have had the smaller version of the phone on hand for some weeks now. As a result I can offer my candid view of the less-covered of the two Pixel handsets (most reviews center around the Pixel XL), and its performance.
There was always a certain cachet to owning a Nexus phone, and you could rest assured that you would be running the latest version of Android before anyone on operator-controlled hardware. The Nexus phones were sold primarily by Google, unlocked, with operator/retail availability at times during their run. Things took a turn when Google opted to offer a carrier-branded version of the Nexus 6 back in November of 2014, along with their usual unlocked Google Play store offering. But this departure was not just an issue of branding, as the price jumped to a full $649; the off-contract cost of premium handsets such as Apple’s iPhone. How could Google hope to compete in a space dominated by Apple and Samsung phones purchased by and large with operator subsidies and installment plans? They did not compete, of course, and the Nexus 6 flopped.
Pixel, coming after the Huawei-manufactured Nexus 6p and LG-manufactured Nexus 5X, drops the “Nexus” branding while continuing the tradition of a reference Android experience - and the more recent tradition of premium pricing. As we have seen in the months since its release, the Pixel did not put much of a dent into the Apple/Samsung dominated handset market. But even during the budget-friendly Nexus era, which offered a compelling mix of day-one Android OS update availability and inexpensive, unlocked hardware (think Nexus 4 at $299 and Nexus 5 at $349), Google's own phones were never mainstream. Still, in keeping with iPhone and Galaxy flagships $649 nets you a Pixel, which also launched through Verizon in an exclusive operator deal. Of course a larger version of the Pixel exists, and I would be remiss if I did not mention the Pixel XL. Unfortunately I would also be remiss if I didn't mention that stock for the XL has been quite low with availability constantly in question.
The Pixel is hard to distinguish from an iPhone 7 from a distance (other than the home button)

Please excuse the bit of self-promotion here. Oh, and disclaimer: Shrout Research and PC Perspective share management and ownership.
Based on testing done by Shrout Research and published in a paper this week, the introduction of Android applications on Chromebooks directly though the Play Store has added a new wrinkle into the platform selection decision. Android applications, unlike Chromebook native apps, have a heavy weight towards the Android phone and tablet ecosystem, with "defacto" optimization for the ARM-based processors and platforms that represent 98%+ of that market. As a result, there are some noticeable and noteworthy differences when running Android apps on Chromebooks powered by an ARM SoC and an Intel x86 SoC.
With that market dominance as common knowledge, all Android applications are developed targeting ARM hardware, for ARM processors. Compilers and performance profiling software has been built and perfected to improve the experience and efficiency of apps to run on ARMv7 (32-bit) and ARMv8 (64-bit) architectures. This brings to the consumer an improved overall experience, including better application compatibility and better performance.
Using a pair of Acer Chromebooks, the R11 based on the Intel Celeron N3060 and the R13 based on the MediaTek MT8173C, testing was done to compare the performance, loading times, and overall stability of various Android Play Store applications. A range of application categories were addressed including games, social, and productivity.
Through 19 tested Android apps we found that the ARM-powered R13 Chromebook performed better than the Intel-powered R11 Chromebook in 9 of them. In 8 of the apps tested, both platforms performed equally well. In 2 of the test applications, the Intel-powered system performed better (Snapchat and Google Maps).
The paper also touches on power consumption, and between these two systems, the ARM-based MediaTek SoC was using 11.5% less power to accomplish the same tasks.
Our testing indicates the Acer R13, using the ARM-powered processor, uses 11.5% less power on average in our 150 minutes of use through our education simulation. This is a significant margin and would indicate that with two systems equally configured, one with the MediaTek ARM processor and another with the Intel Celeron processor, the ARM-powered platform would get 11.5% additional usage time before requiring a charge. Based on typical Chromebook battery life (11 hours), the ARM system would see an additional 75 minutes of usability.
There is a lot more detail in the white paper on ShroutResearch.com, including a discussion about the impact that the addition of Android applications on Chromebooks might have for the market as whole:
...bringing a vast library of applications from the smart phone market to the Chromebook would create a combination of capabilities that would turn the computing spectrum sideways. This move alleviates the sustained notion that Chromebooks are connected-only devices and gives an instant collection of usable offline applications and tools to the market.

Fuchsia is still a work in progress which has been available on Github for a while now but we haven't really seen a demonstration of it in action. A Texan enthusiast has been working on creating one and you can take a peek at it in this video over at The Register. The tiny OS is design to run on almost anything, from smart light bulbs to phone and even full sized computers. It is based on BSD with additional resources developed at MIT and will be backwards compatible with current Android libraries.
"When Fuchsia broke cover last August, we noted the project's ambition. The presence of a compositor indicated it was capable of running on more than lightbulbs and routers, although the tiny new Magenta kernel also allows it go there too."
