Im currently using the Galaxy A32 4G. When you install a privacy screen protector it messes with the sensor so you can use your fingerprint to unlock your phone if it's an under display sensor. I'm not sure what causes that but I'm pretty sure it has...
Coz I've been getting them but I've never won any I don't know whether I should mark as used or unused. Plus there's no notification of who won or where you can check your status
