Menu Navigation Buttons Ghost Touches

Jul 4, 2017
Hi guys, I need your help.

Recently I've updated my Mi4c to Android 7 (7.6.15 MIUI)
After ~1 week of usage when I played comparably heavy CPU intensive game my navigation buttons on the bottom stopped working.
When I removed the screen firm, it went back to workable state, but navigation buttons started to press randomly (menu, home, back). After switching screen on and off everything is fine for ~10 seconds. Afterwards they are being pressed by themselves in random order.
I tried built-in touchscreen test - no ghost touches on actual screen. Everything is working fine for touchscreen itself. But navigation buttons are touched by "ghosts"

Did anyone faced same problem? Please, advice

my phone is having the same issue. random buttons press. I changed a lot of roms and it is the same problem for all of them. I am afraid this might be a hardware problem. It is becoming more and more frustrating to me as my phone do this random stuff every single day plenty of times. I am going to buy a new phone. This is my first xiaomi phone and I am disappointed because I only had this phone for 9 months
