I'm having a really weird touchscreen glitch since 3 days. Most of the times when I start my phone the touchscreen straight up does not work at all. Then I need to restart it using the volume down and power button and after 2 or 3 tries it works. but only for a short amount of time. Sometimes I can only enter two numbers of my pin, sometimes I can use it for 5 minutes or till the touchscreen randomly stops working. I already hard reset the phone and did all the updates in the time the touchscreen was working a for a few minutes. I dont really know what I should do to fix it
