not sure how this one slipped by me but, if you used iCloud or Find My iPhone for IOS, you should try Cerberus for Android.
like $5 does mostly the same stuff like:
-Lock your Android phone
-remote wipe of Micro SD and phone
-send a text to phone
-sound an alarm on the phone
-send text to VOICE on the phone EG: type in "Fuck your couch N1ggah!" and it will read -it out loud.
-take a photo or video remotely and send it to your email
-track your phone (obviously)
app can't be uninstalled without password (not sure about flashing)
lots more but i havn't gone through it all yet.
you get a 1 week free trial. no subscription, just buy once.
