[Q] M8 touchscreen partially not working topic

So suddenly out of no where the top part of my M8 stopped working.. Its like the top 1 - 1.5 cm is not responding to anything. I cant pull down the notification bar as an example.

I've tried to reset the device completely and install another rom.. Still not working.. I cannot determine if this is also the case in TWRP since theres nothing to test on op there..

Is there something i can do to make certain its not a software fault? Calibrate the screen ?
