Worries Mount Over Upcoming LTE-U Deployments Hurting Wi-Fi 59

alphadogg writes: LTE-U is a technology developed by Qualcomm that lets a service provider broadcast and receive signals over unlicensed spectrum, which is usable by anybody – specifically, in this case, the spectrum used by Wi-Fi networks in both businesses and homes. By opening up this new spectrum, major U.S. wireless carriers hope to ease the load on the licensed frequencies they control and help their services keep up with demand. Unsurprisingly, several outside experiments that pitted standard LTE technology or 'simulated LTE-U' technology, in the case of one in-depth Google study, against Wi-Fi transmitters on the same frequencies found that LTE drastically reduced the throughput on the Wi-Fi connection.

From Microsoft, HoloLens VR Dev Kit, New Phones, Continuum 49

Ars Technica and scads of other tech hardware sites are reporting that the big news so far from this morning's Microsoft product launch event in New York is that the company's Hololens development kit will begin shipping in the first quarter of next year, and at a price that puts the units out of the hands of typical consumers: $3000. At that level, developers are more likely to make the plunge, which Ars applauds.

The company also announced three new smartphones: two of them, the Lumia 950, 950XL, are worth designating "flagships," while the 550, notably, will sell for $139, putting it in the territory of cheap grey-market Android phones. More interesting than spec bumps, though, is Continuum for Windows, a Window 10 feature which made its official debut at the event. Continuum is one manifestation of the pocket-computer idea that others have had as well in various forms: it means that with an adapter, a phone can be used as the CPU and graphics engine when connected to a screen and keyboard: "The adapter features a Microsoft Display Dock, an HDMI and Display Port, plus 3 USB ports to provide productivity on the go and let you plug in additional peripherals, such as mice and keyboards. Other accessories can be connected too, Microsoft said."

Microsoft also demo'd the Surface 4. Its improved screen is 12.3" at 2160x1440, for a pixel density of 267 PPI. The new pro has a Skylake 6th-gen processor, which they say provides a 30% performance boost over the Surface Pro 3, and a 50% boost over the MacBook Air. The SP4 goes up to 1TB of storage, and up to 16GB of RAM. The Type Cover was improved as well — the touchpad is 40% larger and supports 5-point multi-touch, while the keys have better travel and pitch.

On top of this, Microsoft also unveiled the Surface Book laptop. Its defining feature is that you can unclip the 13.5" touchscreen and use it separately as a tablet. The keyboard dock has a dedicated GPU that will boost performance when attached. Microsoft is using a new type of hinge that bends and extends at multiple points, so you can also reattach the screen backward if you want to use it as a tablet while keeping the extra GPU power available. They claim a 12-hour battery life for the Surface Book.

Advertising Malware Affects Non-Jailbroken iOS Devices 69

An anonymous reader writes: Malware called YiSpecter is infecting iOS devices belonging to Chinese and Taiwanese users, and is the first piece of malware that successfully targets both jailbroken and non-jailbroken devices, Palo Alto Networks researchers warn. What's more, the techniques it uses for hiding are making it difficult to squash the infection. YiSpecter's malicious apps were signed with three iOS enterprise certificates issued by Apple so that they can be installed as enterprise apps on non-jailbroken iOS devices via in-house distribution. Through this kind of distribution, an iOS app can bypass Apple's strict code review procedures and can invoke iOS private APIs to perform sensitive operations.

Some Apple iPhone 6s and 6s Plus Smartphones Mysteriously Powering Down 53

MojoKid writes: Apple's iPhone 6s and 6s Plus were two of the most highly anticipated smartphones to launch so far this year. The excitement surrounding Apple's new refresh cycle flagships was so great that Apple reported record first weekend sales, with 13 million devices finding their way to customers. However, it appears that some of those customers are having a puzzling issue with their brand new iPhones. Owners are reporting that their phones are turning off randomly when left alone — even when the smartphones have sufficient battery remaining. "New Phone 6s 128GB turned off for no reason the last two nights," wrote Joachim Frey in an Apple discussion thread. "In the morning you then have to push the power-on button for a long time to get it started."

Samsung Decides Not To Patch Kernel Vulnerabilities In Some S4 Smartphones 133

An anonymous reader writes: QuarksLAB, a security research company, has stumbled upon two kernel vulnerabilities for Samsung Galaxy S4 devices, which Samsung has decided to patch only for recent devices running Android Lollipop, but not Jelly Bean or KitKat. The two vulnerabilities (kernel memory disclosure and kernel memory corruption) were discovered in February 2014 and reported to Samsung in August 2014, affecting the samsung_extdisp driver of Samsung S4 (GT-I9500) devices. Bugs break ASLR and lead to denial of service (DoS) state or even elevating attacker privileges.

Motorola Marketed the Moto E 2015 On Promise of Updates, Stops After 219 Days 123

An anonymous reader writes: Over the past few years, Motorola has emerged as one of the best manufacturers for low-to-mid-range Android phones. Unlike many other major manufacturers, they keep their version of Android close to stock in order to keep OS updates flowing more easily. When they began marketing the Moto E 2015, updates were one of the features they trumpeted the loudest. But after the company published a list of devices that will continue to get updates, Android Police found the Moto E to be conspicuously absent. The phone launched on February 25, a mere 219 days ago. According to an official Motorola marketing video from launch day, "...we won't forget about you, and we'll make sure your Moto E stays up to date after you buy it."

Sprint To Begin Layoffs, Cut $2.5 Billion In Expenses 55

An anonymous reader writes: Sprint's struggles to remain a major carrier continue. Just a few days after announcing that it is dropping out of a major low-band spectrum auction, the company now says it must cut between $2 billion and $2.5 billion in costs over the next six months. The cuts will need to be aggressive — according to the Wall Street Journal (paywalled), Sprint "had $7.5 billion in operating expenses during the three months ended June 30," even as it cut $1.5 billion over the past year. The only good news for Sprint is that its subscriber base is still slowly growing, though not quickly enough to keep pace with T-Mobile, let alone Verizon or AT&T.

$50 Fire Tablet With High-capacity SDXC Slot Doesn't See E-books On the SD Card 143

Robotech_Master writes: For all that the $50 Fire tablet has a 128 GB capable SDXC card slot that outclasses every other tablet in its price range, and it evolved out of Amazon's flagship e-book reader, it strangely lacks the ability to index e-books on that card. This seems like a strange oversight, given that every other media app on the tablet uses that card for downloading and storage, and its 5 GB usable internal memory isn't a lot for people who have a large library of picture-heavy e-books—especially if they want to install other apps, too.

Xiaomi Investigated For Using Superlatives In Advertising, Now Illegal In China 108

An anonymous reader writes: Chinese smartphone maker Xiaomi is under investigation for using superlative messaging on its website, according to a leaked document from the Beijing Ministry of Industry and Commerce. A new Chinese law states that adjectives used to promote products must not mislead consumers. The Xiaomi investigation [Chinese] follows claims made by rival Cong that the company used phrases such as 'the best' and 'the most advanced', in its online campaigns and therefore violated the country's advertising law. (The law against suprelatives doesn't seem to apply to communications by the government, about the government.)

Stagefright 2.0 Vulnerabilities Affect 1 Billion Android Devices 123

msm1267 writes: Security researcher Joshua Drake today disclosed two more flaws in Stagefright, one that dates back to the first version of Android, and a second dependent vulnerability that was introduced in Android 5.0. The bugs affect more than one billion Android devices, essentially all of them in circulation. One of the vulnerabilities was found in a core Android library called libutils; it has been in the Android OS since it was first released and before there were even Android mobile devices. The second vulnerability was introduced into libstagefright in Android 5.0; it calls into libutils in a vulnerable way. An attacker would use a specially crafted MP3 or MP4 file in this case to exploit the vulnerabilities. Google has released patches into the Android Open Source Project tree, but public patches are not yet available.

The Real Cost of Mobile Ads 117

New submitter cvdwl writes: A New York Times (mildly paywalled) article and associated analysis discuss the consumer cost of mobile ads, assuming a US$0.01/MB data plan. The article provides one of the only estimates I've seen of the the real cost in time and money (and time is money) of mobile advertising. Ethics of ad-blockers aside, this highlights the hidden costs of data-heavy (often lazy and poorly developed) web-design. In a nutshell, the worst sites took 10-30s load 10-20MB, costing $0.15-0.40, over 4G due to a blizzard of video, heavy images, and occasionally just massive scripts. The best sites had high content to ad ratios, typically loading 1-3MB of content and >500kB of advertising.

Advance In Super/Ultra Capacitor Tech: High Voltage and High Capacity 146

fyngyrz writes: Ultracaps offer significantly faster charge and discharge rates as well as considerably longer life than batteries. Where they have uniformly fallen short is in the amount of energy they can store as compared to a battery, and also the engineering backflips required to get higher voltages (which is the key to higher energy storage because the energy stored in a cap scales with the square of the cap's voltage, whereas doubling the cap's actual capacitance only doubles the energy, or in other words, the energy increase is linear.) This new development addresses these shortcomings all at once: considerably higher voltage, smaller size, higher capacitance, and to top it off, utilizes less corrosive internals. The best news of all: This new technology looks to be easy, even trivial, to manufacture, and uses inexpensive materials — and that is something neither batteries or previous types of ultracaps have been able to claim. After the debacle of EEStor's claims and failure to meet them for so long, and the somewhat related very slow advance of other ultracap technology, it's difficult not to be cynical. But if you read TFA (yes, I know, but perhaps you'll do it anyway) you may decide some optimism might actually be called for.

iOS 9 'Wi-Fi Assist' Could Lead To Huge Wireless Bills 182

Dave Knott writes: One of the new features introduced in iOS9 is "Wi-Fi Assist." This enables your phone to automatically switch from Wi-Fi to a cellular connection when the Wi-Fi signal is poor. That's helpful if you're in the middle of watching a video or some other task on the internet that you don't want interrupted by spotty Wi-Fi service. Unfortunately, Wi-Fi Assist is enabled by default, which means that users may exceed their data cap without knowing it because their phone is silently switching their data connection from Wi-Fi to cellular.

Amazon Launches 'Flex,' a Crowdsourced Delivery Service 145

sckirklan writes: Amazon has rolled out a new service called Amazon Flex. It lets people sign up to deliver packages using their mobile phone and their car, earning $18-25/hr while doing so. Think Uber, but for package delivery. Their goal is to fully support one-hour delivery within certain cities. The service is available in Seattle to start, and it'll soon expand to Manhattan, Baltimore, Miami, Dallas, Austin, Chicago, Indianapolis, Atlanta, and Portland. No news on what they think of bicycle couriers, but given their focus on being green, I'd imagine something is in the works.

Google Shows Off 2 New Nexus Phones, a New Pixel, and More 208

Two of the products officially unveiled at Google's much-anticipated (at least much-hyped) release announcement were widely and correctly predicted: a pair of new Nexus phones. The flagship is the all-metal Huawei 6P, with a 5.7" AMOLED display (2,560x1,440), 3GB of RAM, and a Snapdragon 810 chip. The Huawei overshadows the nonetheless respectable second offering, the LG-made Nexus 5X, which makes concessions in the form of less RAM (2GB instead of the 6P's 3), smaller battery (2700mAh, instead of 3450) and a lesser Snapdragon chip inside (808, rather than 810). Both phones, though, come with USB-C and with a big upgrade for a line of phones not generally praised for its cameras: a large-pixel 12.3-megapixel Sony camera sensor. Much less predicted: Google announced a new bearer for the Pixel name, after its line of high-end Chromebooks; today's entrant is a tablet, not running Chrome, and it's running Android rather than Chrome OS. The Pixel C tablet will debut sometime later this year; google touts it as "the first Android tablet built end-to-end by Google." Also on the agenda today, news that Android 6 will start hitting Nexus devices next week.
