I recentl had issues with my Switch that can't seem to enable WIFI, and after a few months, it started to stop working in handheld mode as the screen only displays black, but works ok when docked. So i decided to open it and check inside for whats causing it. After, i remove the metal plate, i discovered a metal part lodge on top of the wifi antenna. (image attached) and on the board that has the antenna connector. Anyone knows if this came from the switch?
