Well, anti theft sends a pre-entered number a warning that an other SIM is in it. Via sms commands, you can turn GPS on, send the location, block root and stuff.
It wont be deleted as it is a system app
I use it.
Thanks for the job, needed this for hacking my bros phone xD
All true, if speaking of a casual thief- maybe you left the phone on the bar and someone couldn't resist the temptation. A couple of months ago my wife's phone was recovered in such an occasion- got an sms from Avast Theft Aware with the new number, contacted the rather surprised "honest finder" and he decided to return it back to us.
Anyway, two weeks ago went scubadiving and when returning to the car found the window broken and sure, among other stuff (wallets, scuba gear etc) also both our phones were stolen. However, this time it looks like the thieves were not quick to put their own sim card. Actually, it looks like they've removed the batteries, thrown the sim cards away (the're useless anyway as the carrier blocks the sim).
Since then, no signs whatsoever that the phones have been turned on, sims replaced or that someone has tried to type wrong security pin or whatever- no sms notifications, no emails, no webtracking, nothing.
My guess- the thieves sell them for a small fee (20% of street price?) to some lab or someone who knows "how to deal with it"- do a good wipe (not just factory reset) and remove whatever stuff was installed- system app or not- then put them on market for sale as second hand. Or maybe they just wait with patience a few weeks until you stop looking for it?
So, sometimes these apps like Avast, Cerberus and the such work, sometimes not. Better to keep the phone safe and not rely on it being stolen by a stup!d thief...
On the bright side, one can consider it as an opportunity for upgrade
