I have Galaxy Note 10 Plus and I got its back glass broken, I got it repaired from nearby authorised service centre and now Im having screen issues, my screen is not physically damaged and after the repair was done, whenever screen was off and I unlocked my phone or tried tapping screen it would show screen with green bars then it will work good and won't give any problems. Its just like cold starting your engine, I get screen flicker when I turn on screen and afterwards it doesn't occur.
