An anonymous reader writes "SFGate reports that Stanford researchers have figured out a way to generate a unique fingerprint from a cell phone's suite of built-in sensors. The tiny accelerometers, gyroscopes, microphones, and speakers in cell phones have characteristics that vary slightly from handset to handset, and these variations may contain enough information to uniquely identify a given handset. How that information might get from the phone to a third party varies (the article describes a JavaScript snippet reading the Z-axis accelerometer, though it says little about how the user might block such information from being read), but the possibility for abuse is certainly troubling."

Nate the greatest writes "Guilford County Schools' headline grabbing tablet program is back in the news again. The program came to an abrupt end last Friday when the school district announced that they were recalling all of the Amplify tablets. GCS had leased over 15 thousand of the tablets (at a cost of $200 a year) for its middle school students, but decided to recall the tablets just one month into the school year after some 1500 students reported a broken screen. Around two thousand complained of improperly fitting cases, and there were also 175 reports of malfunctioning power supplies. There's currently no explanation for the cases or power supplies, but GCS has stated that the tablets broke because they lacked a layer of Gorilla Glass. This was listed in the contract, but the school district did not confirm the condition of the tablets before accepting them. This program was the poster child for News Corp.'s entry into the educational market. It was the single largest program to use the Amplify tablet, and its failure represents a serious setback. The Amplify tablet now has a record for poor construction quality and a breakage rate that is 12 times higher than what Squaretrade reported in early 2012 for the iPad 2."

Features of Google's next Nexus phone have finally been outed, along with confirmation that the phone will be built by LG, as a result of a leaked service manual draft; here are some of the details as described at TechCrunch: "The new Nexus will likely be available in 16 or 32GB variants, and will feature an LTE radio and an 8-megapixel rear camera with optical image stabilization (there’s no mention of that crazy Nikon tech, though). NFC, wireless charging, and that lovely little notification light are back, too, but don’t expect a huge boost in longevity — it’s going to pack a sealed 2,300mAh battery, up slightly from the 2100mAh cell that powered last year’s Nexus 4. That spec sheet should sound familiar to people who took notice of what happened with the Nexus 4. Just as that device was built from the foundation laid by the LG Optimus G, the Nexus 5 (or whatever it’s going to be called) seems like a mildly revamped version of LG’s G2."

Microsoft made some confident sounding claims about sales of its first-generation Surface tablets before it became clear that the tablets weren't actually selling very well. So make what you will of the company's claim that the second version is "close to selling out." As the linked article points out, the company has "fallen short of offering any real explanation as to just how “close” to selling out the Surface 2 and Pro 2 really are – nor have they indicated how many were on hand to order in the first place."

quantr draws your attention to a Bloomberg report that Microsoft has reached out to HTC to see if the company would be interested in adding Windows as a second OS to its Android handsets. From the Bloomberg story: "Its willingness to add Windows as a second operating system underscores the lengths to which Microsoft will go to get manufacturers to carry its software. HTC, the first company to make both Windows and Android phones, hasn’t unveiled a new Windows-based handset since June and has no current plans to release any more, said one person. Microsoft, with 3.7 percent of the market, is finding it necessary to make concessions after agreeing to acquire Nokia Oyj’s handset unit, which competes with other smartphone makers. [Microsoft operating systems head Terry] Myerson was planning to visit Asia this month and meet with senior executives at Taoyuan, Taiwan-based HTC to discuss his proposal, one of the people said."

An anonymous reader writes "After Samsung got caught out cheating on benchmarks (Note 3, Galaxy S4) AnandTech has done a detailed analysis of the state of benchmark cheating amongst Android OEMs. With the exception of Motorola, literally every single OEM they've looked at ships (or has shipped) at least one device that does benchmark-specific CPU optimizations. AnandTech also thinks it will get worse before it gets better. 'The hilarious part of all of this is we’re still talking about small gains in performance. The impact on our CPU tests is 0 - 5%, and somewhere south of 10% on our GPU benchmarks as far as we can tell. I can't stress enough that it would be far less painful for the OEMs to just stop this nonsense and instead demand better performance/power efficiency from their silicon vendors.' The article notes that Apple doesn't do any of the frequency gaming stuff."

tlhIngan writes "A few months ago, Samsung was caught gaming benchmarks on the Galaxy S4 (International version). They would lock the GPU at a higher-than-normal frequency when certain applications were run, including many popular Android benchmarking programs. These had the expected result of boosting the performance numbers. This time, the Galaxy Note 3 was caught doing the same thing, boosting CPU scores by 20% over the otherwise identical LG G2 (which uses the same SoC at the same clock). Samsung defends these claims by saying the other apps make use of such functionality, but Ars reversed-engineered the relevant code and discovered it applied only to benchmark applications. Even more damning was that the Note 3 was still faster than the G2 when run using 'stealth' (basically renamed) versions of the benchmarking apps which did not get the boost."

mikejuk writes "We all do it — place our phones down on the desk next to the keyboard. This might not be such a good idea if you want to keep your work to yourself. A team of researchers from MIT and the Georgia Institute of Technology have provided proof of concept for logging keystrokes using nothing but the sensors inside a smartphone — an iPhone 4 to be precise, as the iPhone 3GS wasn't up to it. A pair of neural networks were trained to recognize which keys were being pressed just based on the vibration — and it was remarkably good at it for such a small device. There have been systems that read the keys by listening but this is the first system that can hide in mobile phone malware."

dryriver writes "We've seen real laser guns before pulling off tricks like starting small fires, or popping black balloons. That's cool, sure, but it's got nothing—on this handheld laser rifle. Developed by TWI this laser-cutter was initially designed for use by robots, but a few recent tweaks including a pistol-grip and a trigger made it into a human-sized rifle. It is designed specifically with nuclear decommission in mind, specifically chopping up huge pieces of metal infrastructure into bite-sized bits that are easily disposed of. And while it's definitely suited for that, it has some short-comings compared typical rifles. That range is pretty low, for instance, and it's not exactly mobile."

KentuckyFC writes "The remarkable growth of mobile phone use is transforming many parts of Africa. In Sudan and Gabon, more than half of all adults use their phones to transfer money, the activist website Ushahidi used text messages to map post-election violence in Kenya in 2008 and in Nigeria, mobile music services are a multi-million dollar industry. Now demographers have used the way people purchase airtime to map wealth in Cote d'Ivoire on Africa's west coast. They analysed a dataset from one of the country's largest mobile operators containing caller IDs, the cell towers used for each call and the time and amount of all airtime purchases. The researchers say an individual's airtime buying habits are a good proxy for his or her income. As a result, they were able to to map wealth across the entire country. Their map clearly shows the wealthy cities such as Abidjan, the largest seaport in West Africa. But it also shows an unexpectedly wealthy region in the conflict-ridden area that borders Liberia. This wealth probably arises from illegal activities on the border, such as drug, arms and human trafficking, they conclude."

colinneagle writes "Members of an FAA advisory panel are reportedly meeting this week to make changes to the ban on the use of electronic devices on an airplane during takeoff and landing. The new regulations will allow the use of electronic devices to access content stored on the devices, including e-books, music, podcasts, and video. Sending emails, connecting to Wi-Fi, and making phone calls will still be prohibited. The announcement is expected to be made later this month, and the rules put into effect next year, according to the report."

Dputiger writes "Microsoft has unveiled both the Surface 2 and Surface 2 Pro, updating the former with a Tegra 4 processor and the latter with a new Haswell chip. Among the additional improvements are a more comfortable kickstand with two height settings, 1080p displays for both devices, USB 3.0 support, better battery life, and a higher resolution camera. Pricing for the 32GB Surface without a Touch or Type Cover is set at $449."

MTorrice writes "By attaching a lightweight, inexpensive device to the back of a smart phone, scientists can convert the phone into a sensitive fluorescence microscope. The attachment [paper abstract] allows the phone's camera to take pictures of single nanoparticles and viruses, possibly providing a portable diagnostic tool for health care workers in developing countries. For example, doctors in remote regions could use the technique to measure HIV viral loads in patients' blood samples, allowing the doctors to easily monitor disease progression and determine the best course of treatment."

crookedvulture writes "Nvidia has already produced a gaming handheld based on its quad-core Tegra 4 SoC. Today, the company announced plans to build a 7" Tegra Note tablet that uses the same chip. Rather than selling the tablet itself, Nvidia will make the device available through parters like EVGA and PNY. Asking price: $199. That seems a little steep given the Tegra Note's 1280x800 display resolution, which delivers a much lower PPI than the 1080p panel in the latest Nexus 7. But the Tegra Note does have some perks, including front-facing speakers, Micro HDMI output, microSD expansion, and an optional stylus. The tablet also boasts a fancy camera that taps into the Tegra chip's photography engine. Nvidia promises to keep the device updated with the latest versions of Android, too. You can expect to see the Tegra Note for sale worldwide in the next few months."

Nate the greatest writes "Rumors are circulating that Barnes & Noble is going to release their new hardware soon. Two different sources inside B&N have confirmed that a launch is imminent, with one saying B&N will launch both a tablet and an ereader. The other says that a new tablet is coming. I tend to think that the first source is probably right because product pages for several accessories leaked in early August. The pages referenced 2 different new models. Also, B&N recently announced plans to continue to develop both new ereaders and tablets, though they've changed their minds so much that I don't know if that announcement is worth anything."

crookedvulture writes "Bay Trail has its first convertible design win. Intel's newest SoC will be available in Asus' Transformer Book T100, which combines a 10.1" Windows 8.1 tablet with a keyboard dock that includes a gesture-friendly touchpad and USB 3.0 connectivity. The tablet is powered by an Atom Z3740 processor with quad cores clocked at up to 1.8GHz—600MHz slower than the Z3770 chip benchmarked by the press. The screen has a relatively low 1366x768 resolution, but at least the IPS panel delivers wide viewing angles. Asus clearly intends the T100 to be an entry level device; the 32GB version is slated to sell for just $349, and the 64GB one will cost only 50 bucks more. Those prices include the keyboard dock and a copy of Microsoft Office Home & Student 2013. They also bring Windows 8 convertibles down to truly budget territory, completing the collision between tablets and netbooks."

jfruh writes "When Sony announced the PS Vita TV yesterday, most observers saw it as competition for the Apple TV and Roku, or maybe the Ouya. But gaming writer Peter Smith views it differently; he thinks that remote play, including the ability to stream games from the upcoming PlayStation 4 console, will be the Vita TV's killer-app. In that sense, it isn't so much a low-cost replacement for casual gamers as an add-on to the high-end PS4. '[W]hen you're in the middle of a game and someone wants to watch TV, you can just grab a Vita and keep on playing. (This is similar to the popular "tablet play" feature of Nintendo's Wii U, without the Wii U's limitation of having to stay in close proximity to the base console.) ... For any Playstation 4 household with more than one TV I think the PS Vita TV will become a 'must-have' accessory; it's almost like getting a second PS4 for $100.'"

Dave Knott writes "Sony today announced the PS Vita TV box. Measuring 6.5cm by 10.5cm, it can play Vita games on your television, stream content via HDMI or wirelessly, and play all the existing PlayStation Network content available on the standard Vita platform. This is seen by some analysts as an attempt by Sony to compete with such devices as the Ouya and Apple TV. The PS Vita TV is so far announced for a Japan-only release in early 2014 at a price of approximately $100 US. In related news, Sony also announced a lighter, slimmer, more colorful iteration of the standard Vita handheld console." The $100 model does not come with a controller; a $150 model was also announced that will include a Dualshock 3 and an 8G memory card.

Ars Technica reviewer Casey Johnston gives a mildly positive review to the Oyster book-rental app (and associated site), which intentionally tries to be for books what Netflix has become for movies: a low-price, subscription-based, data-sifting source of first resort. For $10 a month, users can read any of the books in Oyster's catalog (in the range of 100,000, and growing), and their reading habits are used to suggest new books of interest (with some bum steers, it seems, at present). It's iOS-only for now, with an Android version expected soon. I've only grudgingly moved more and more of my reading to tablets, but now am glad I have; still, I don't like the idea of having my books disappear if I don't pay a continuing subscription.

An anonymous reader writes with a report from Spiegel Online that the U.S. government "has the capability of tapping user data from the iPhone, [and] devices using Android as well as BlackBerry, a system previously believed to be highly secure. The United States' National Security Agency intelligence-gathering operation is capable of accessing user data from smart phones from all leading manufacturers. ... The documents state that it is possible for the NSA to tap most sensitive data held on these smart phones, including contact lists, SMS traffic, notes and location information about where a user has been." As a bonus, the same reader points out a Washington Post report according to which "The Obama administration secretly won permission from a surveillance court in 2011 to reverse restrictions on the National Security Agency's use of intercepted phone calls and e-mails, permitting the agency to search deliberately for Americans' communications in its massive databases ... In addition, the court extended the length of time that the NSA is allowed to retain intercepted U.S. communications from five years to six years — and more under special circumstances, according to the documents, which include a recently released 2011 opinion by U.S. District Judge John D. Bates, then chief judge of the Foreign Intelligence Surveillance Court."
