I have the same no touch issue but there is no physical damage on the outside of my S20 FE 5G. I tried force restart but it won’t fix the issue, I tried going to recovery mode and clear cache partition but doesn’t work. I tried to drop my phone on a safe area but not to the point that would damage the phone. just to make sure that the connectors from the screen is secured to the motherboard, still not working. then i tap my phone with 2 fingers everywhere even the camera bumb as well. still not working. but I am still at my lock screen that said “Swipe to unlock”. but for now I just call ppl vi Facebook…
