Get Lock Device old version APK for Android
위젯에 하나의 탭에서 장치를 잠금!
A very simple widget to lock your device with a single touch. Useful for big devices hard to lock one handed or when it's sitting on a table. Also useful when the power button becomes defective! It has multiple widget styles available and a launcher shortcut (like an app icon) is also included.
This app uses the Device Administrator permission.
The Device Administrator permission is required to lock the screen. **** IMPORTANT - IT MUST BE DISABLED IN Settings > Security > Device Administrator, or press Deactivate in the Play Store IN ORDER TO BE ABLE TO UNINSTALL IT!! **** Sorry for the caps :(
Button to donate inside the app if you wish to support me :)
