IMPORTANT NOTE FOR HUAWEI AND XIAOMI USERS
Huawei and Xiaomi devices have evil task killer services that interfere with the AppLock service. For our app to work, you need to add App Locker to allowed apps in those devices' security settings.
Huawei: Phone Manager App > Protected Apps > Add App Locker to the list.
Xiaomi: Services > Security > Permissions > Autostart, find App Locker and enable autostart.
