Horizontal sections of touchscreen go dead sometimes
Okay, something is up with my touchscreen.
The part without the dots, and the yellow part I highlighted, keep randomly dying. However if I reboot the phone the touch works fine again for a few minutes. It also can randomly start working again.
Seeing how it works after I restart, is it possibly a software issue?
How can I find out what is causing it and fix it (if it is a software issue)?
