After upgrade to Android 4.4.2, the Anti-Theft became totaly useless :-(. Nothing works.
Changed SIM - no trace abou this and automaticaly set as trusted.
Locate - no reply in half hour.
Take picture - the same.
I tried reinstal - behavior no changed. Start diagnostics - no problems detected. In same time i tested google device manager and by ex. location request was responsed in 5 sec.
So the premium version I bought is currently waste of money.
