About 30% of the time, when I unlock my S9, the screen briefly comes alive, and then turns black. Often the top ~5% of the screen is still visible, but the colors are wrong and it's distorted. I can still interact with the phone, and that 5% of the screen does change in some way, and haptic/sound queues show the phone is working.
This happens most often when I quickly lock and then unlock the phone. It has happened with increasing frequency over the past ~3 months, and now is quite common.
Usually I can fix it by locking again, waiting 10-15 seconds, and unlocking. If I unlock too soon it happens again. However, today after my phone got hot from being in the sun, it took ~20m before it would unlock properly - gave me a scare. Notably, when the phone was stuck this way, I could restart it, and the boot screen showed the Android logo just fine, but as soon as it booted the screen went black again.
To fix it, I've tried a hard restart, full factory reset, and booting in safe mode - nothing seems to affect it. Phone otherwise works great.
Is there anything I can do to fix this? Or do I just need to resign myself to getting a new phone?
