I've been testing a few phone finder type apps on my S3, but can't find anything that works. If you text certain words, they are supposed to either start the phone ringing or send you back the phone's GPS location. I've tried "Find My Phone" and "Where's My Droid." Neither works with text messages sent from Google talk or from another cellular phone. "Where's My Droid" has a web site with a "Commander" function that lets you communicate with your phone. That is a bit slow, but it does work. It will make the phone ring and will bring up its location on Google Maps. Does anyone have a solution for making these apps work with texting, or have you tried other apps that work on the S3? I'm using an ATT S3 phone. Thanks.
