Losing your phone or tablet can be expensive and annoying, and it’s easy to do, especially at a party. I use my tablet for work and I’m always leaving it on a desk somewhere after a meeting.I tried using Android’s "owner info" feature to put my name on the lock screen, but not everyone in the company knows my name. And my phone number is no use if it’s my phone that’s missing!Here’s the answer. With just a few clicks, you can display your photo on the lock screen. Now anyone who picks up your phone or tablet knows who to give it back to! Even if you have the lock screen turned off, you can also add the widget to your home screen.Needs Android version 4.2 Jelly Bean, which is the first version to support lock screen widgets. This app needs the "read your contacts" and "read your own contact card" permissions to display your photo.
