15+ Best App Lock for Android to Secure Your Device

But most phones don’t have such features. This makes it necessary to have a way to lock such apps on the phone or tablet. These locking apps typically ask for a pin or pattern every time one opens selected apps.

A new trend is the use of an app lock fingerprint to secure your device. Some people feel a need to secure their incoming calls. These screen locking apps basically ask for a password or pattern before anyone can answer your phone! Such app lockers also give you an option to hide or lock the caller ID.
