So i first had some issues with the USB port of my Galaxy S6 Edge. I replaced the micro USB port, however the faulty contact issues continued, so i tried to clean the dirt inside the USB plug of the phone with a needle. The USB seems to be charging correctly again, but next thing I know, the touchscreen stopped working. Specifically, It works for five seconds only, and then becomes unresponsive. Barely the time for me to get past the unlock screen.
My guess is that by "cleaning" the micro USB port I might have scratched something, which could mess with the grounding or so. But any guess might be better than mine, plus i have no idea how to repair such a thing. Any ideas?
