So you've lost your locked smartphone or tablet? Here's how to get it back... ANDROID

Android

If you have Jelly Bean or better this option is baked in for you. I'm grateful to my Twitter friend Terence Eden for patiently pointing this out to me despite my remonstrations that I didn't think it was there...

Go into Settings - Security, and under there you will find Owner Info.

Go into that, put whatever you want in:

Configuring owner information on Android.

...and that information will appear on the lock screen.

Owner information displayed on the Android home screen.

OK, so that's easy, and well worth doing.
