This sounds like you recently installed a new screen on your iPhone, because when you use non genuine parts, these problems could appear.
To check if they are genuine, read this article: iPhone parts and service history - Apple Support, this will help.
If you didn't repair your screen, and this error still appears,
please contact Apple Support.
Hope this helps!
