We’ve seen lots of Android apps that offer inventive ways to secure your smartphone, but I don’t think any of them are as interesting as Ergo from Descartes Biometrics. Ergo lets you unlock your smartphone using the unique geometry of your ear, so gaining access to your device is as easy as placing it against your face.

Samsung “isn’t sure” about announcing its next-generation Galaxy S5 at Mobile World Congress next month after reliable Russian tipster Eldar Murtazin revealed the date of the event. Murtazin now believes the South Korean company could delay the announcement and hold a special event in London as previously reported.

I wrote about some of the major flaws affecting the Google Play Edition Sony Xperia Z Ultra on Monday, but fortunately, these are being fixed with a new Android 4.4.2 update rolling out today. The release weighs in at just over 441MB, and it comes with build number KOT49H.

If you set up your new Google Play Edition Xperia Z Ultra by restoring from a backup of your previous Android-powered handset, you probably ended up with a whole bunch of apps you no longer use or need. But that’s okay, because you can just go through your app drawer and uninstall them all… right?

Wrong. It seems the new handset carries a frustrating bug that causes the handset to restart itself when its user attempts to uninstall an app.

If you’re a forgetful smartphone owner who likes to leave their device in cabs and coffee shops, then why not make it easier for people to return your handset to you by adding your contact details to the lock screen? It’s quick and easy to do, and it’s a feature that built right into Android, so you don’t even need a third-party app.
