There are custom firmware that is unofficial.Many mobile applications are able to get full access to the user's personal information, transmit it over the Internet, make calls and send SMS to suspicious numbers, etc.With the help of these firmware programs run in the "incognito" and the application will not be able to get access to personal data.For them, the user's contact list, browser history, calendar
events, and messages will look completely blank.Even if the phone or tablet will include a GPS navigator, the application will not know about it and can not determine the user's location.

applications may also notify the owner of the phone by SMS when it is lost.For this pre-defined by a list of other SIM-cards, which will be seen by the application as legally and which will receive an SMS with information such as the IMSI-number of the inserted SIM card and phone's location (based on the data network, GPS, or Wi-Fi).
In addition, there is an option of automatic protection switching system each time you start the phone, or when it detects an unknown SIM card.There are applications, able to photograph the face of the thief, to record his voice to report numbers to which the calls were made, change the volume of ringtone, etc.
