This is a classic case of touch disease. The correct PERMANENT fix is to have Meson (touch IC chip) removed and a jumper put in place from the M1 pad to the corresponding circuit trace/pad. The issue is the M1 pad gets a micro tear/crack/break, etc and makes intermittent contact with the adjacent trace. The chip itself is (in my opinion) not to blame at all, but rather this defect in the PCB itself. You can normally reball Meson and put back in after putting in the trace jumper. A quick Youtube search for touch disease will have results including the M1 jumper mod. If you are unable to do the repair yourself, find a reputable shop that offers the service and send it to them. Hope this helps.
