    My OnePlus 6 devices have problems with the fingerprint scanner. Sometimes it works sometimes it don't. I need to restart the device everytime I want to use it. One time, the device says, "Fingerprint Hardware is not available on this device" when I use the app locker. Please response for my problems what should I do :(
