How is my friend bypassing Applock application I'm using moto x 2nd gen, I recently installed applock to keep some apps private but one of my friend knows a way to bypass the password and even change it, he did the same even with pattern lock. He doesn't even reboot the phone, he does it in seconds. How is he doing it and in what other ways can I lock my apps?
One possible answer can be that he is killing the application process that is protecting your device. One possible way is that he goes to Settings->Apps->[applock_application] and then Force Stop it.
