Smart Phones are no longer a simple hand through which we could call a person or could send out message massage therapies to somebody; instead it is an accumulation of hand collection, electronic daily record, bridge to net, amusement source and so on. For lots of purposes we have set up many applications in our cell phone that we could not also remember them up until we are in real demand of them. Several of those applications are so helpful and also private that we need real safety and security to shield them from unwanted entry and un-authorized un-installation. For this kind of inconvenience, first thing comes in my thoughts is AppLock.
