You’ll Never Believe the Data ‘Wiped’ Smartphones Store

Posted on by

So what can you do about all this the next time you’re ready to upgrade phones? The alarming answer is not much. According to Reiber, all of our volunteers did the right thing. They used the software tools available to restore each phone to its factory settings. But that didn’t matter. The data is still there, if you have the means to recover it. In fact, Reiber says there’s only one surefire way to make sure someone isn’t going to come along behind you and scarf up your old bits: Take a hammer to it.

Another reason not to use your mobile gadget for storing any sensitive information.  Here’s a link to MPE+ Mobile Phone Forensics mentioned in the article.  Here’s a sample of their features:

PHYSICAL IMAGING OF ANDROID DEVICES

MPE+ enables physical imaging of Android devices. MPE+ features built in rooting functions that allows the physical analysis of any partition on an Android device. No need to pay for additional “rooting” suites.

‘Bezos Beep’ could replace the smartphone bump for mobile content sharing

Posted on by

For example, if the user of an e-reader or smartphone wants to share a book or picture with someone else, that person’s phone will transmit an audible signal that can be received and decoded by other devices within earshot. The decoded signal contains information (such as a URL) allowing the receiving device to download the shared content from a remote server.

LOL.  Someone reinvented the 300 baud modem.

Understanding Camera Optics & Smartphone Camera Trends, A Presentation by Brian Klug

Posted on by

For readers here I think this is a great primer for what the state of things looks like if you’re not paying super close attention to smartphone cameras, and also the imaging chain at a high level on a mobile device.

Some figures are from of the incredibly useful (never leaves my side in book form or PDF form) Field Guide to Geometrical Optics by John Greivenkamp, a few other are my own or from OmniVision or Wikipedia. I’ve put the slides into a gallery and gone through them pretty much individually, but if you want the PDF version, you can find it here.

Smartphone Screen Real Estate: How Big Is Big Enough?

Posted on by

First, let’s talk small. At just 3.5 inches, the iPhone 4 (and earlier) is relatively small compared to most higher-end phones on the market, yet it’s immensely popular. (Technically, the iPhone 5 has a 4-inch screen, but it’s just longer–not wider–so that doesn’t really count.) Apparently, then, that’s a good baseline for an acceptable screen size for a large swathe of the mobile market.

An App Called Moves Logs Every Step You Take

Posted on by

Created by a startup called ProtoGeo, Moves is free and currently available only for the iPhone (the company plans to release an Android version but hasn’t said when). The app’s precision and power consumption need work, but I’m convinced its simplicity represents the future of self-tracking.

Huawei shows off phone with monster 6.1-inch screen

Posted on by

Running Android 4.1 with a custom Huawei user interface, the phone is dust- and water-resistant, as was demonstrated on stage when Richard Yu, CEO of Huawei’s consumer business group, poured water over the phone’s screen with no apparent problem. He also dropped it on stage, on purpose, to demonstrate toughness.

A Reprogrammable Processor from Coherent Logix Could Handle All Radio, Video, and Photo Processing on a Smartphone or Tablet

“We believe it’s not enough just to put the radios together and put them in software. To get the most powerful, flexible, dynamic system, you want to tie all the video and photo processing together with the radio processing,” says Michael Doerr, the company’s founder and chief technology officer. “And we have a unique processor that can do that, but it’s a question of getting to the right performance and power trade-off.”

China Says It Now Has 1.104B Mobile Users, While Mobile Communications Revenue Totaled $116.26B Over First 11 Months of 2012

Posted on by

The rapid growth of the Chinese smartphone market means that it is set to top the U.S. iOS and Android install base next year. According to a research report by Flurry released last month, China currently has 167 million iOS or Android devices, compared to 181 million in the U.S.

A New Chip Brings Electrical-Field-Based 3-D Gesture Recognition to Smartphones

Posted on by

The low-power chip makes it possible to interact with mobile devices and a host of other consumer electronics using hand gesture recognition, which today is usually accomplished with camera-based sensors. A key limitation is that it only recognizes motions, such as a hand flick or circular movement, within a six-inch range.

The controller comes with the ability to recognize 10 predefined gestures, including wake-up on approach, position tracking, and various hand flicks, but it can also be programmed to respond to custom movements. Similar to the programming of voice recognition software, Microchip Technology built the gesture library using algorithms that learned from how different people make the same movements. These gestures can then be translated to functions on a device, such as on/off, open application, point, click, zoom, or scroll.

Feature phones dwindle as Android powers ahead in third quarter

But Samsung dominated that field as it does the rest of the market: Apple made up 13.9% of the smartphone market, slightly down in share even though its shipment numbers grew by 36%, giving Samsung 32.6% of the entire smartphone market.
