Google launches smartphone trouble-shooting app

The quite aptly named Device Assist is designed to help Nexus device owners fix problems with their handsets and call for back-up when tips and tricks fail.

The quite aptly named Device Assist is designed to help Nexus device owners fix problems with their handsets and call for back-up when tips and tricks fail.

Available to download from Google Play now, the app also offers users an introduction to the new features in Lollipop -- the latest version of the Android operating system -- and tips regarding how to get the most out of it.

Whenever the app is launched, it will automatically display any potential issues that could be causing, or are about to cause, problems along with steps to remedy them.

And, if none of the suggestions work, the app can be used to book a call-back from a Google tech support person who will be able to get right down to business -- the app shares all relevant information about the handset and its settings.

The app is a great idea and there's just one limitation: it only works with Nexus, Google Play editions or Android One handsets.
