Pre Screen Flicker
Sometimes the PRE screen will fade out when making a call or will flicker. This is not a problem of the device. This is actually a feature that is working correctly.
The reason we see this error is because a screen protector or the original protector is left on the screen. My theory is that the screen is heat sensitive and the more you use it with a cover, somehow that heat is being saved/trapped by the cover and causing the screen to go dark. The screen also goes dark when you put it up to your face (so you don’t dial/activate apps while on a call). The screen protector is causing the phone sensor to behave like it’s up to your face. Because the heat will disappate, it will return to a normal look an feel with the screen cover until you crank up some functions that heat up the phone (like talking on it).
In conclusion: don’t use screen protectors on the PRE. Test them first and if you have problems after applying screen protector, then it’s the screen protector causing the problems, not the phone.
