Samsung GT-N7100 Galaxy Note II may be on the market for quite some time. This phone may had been phased out but service technicians still receiving a lot of repairs for this unit.
I have this phone and the most common problem I have with Galaxy Note II is the broken USB charging pin. The entire charging flex is working fine so the only thing I need to change is the very pin. I studied the schematic diagram of Note II and found some interesting data I could use for repairing. One of which is you can directly make a jumper connection from USB charging pin up to the wireless charging connector, it is located near the SIM card reader. The connection was way too long so I made a new jumper ways from the charging pin to the nearest V+charging point and the other one is for the ground (-).
The good thing is that you can use the generic/universal micro USB pin to work with the Samsung GT-N7100 Galaxy Note II.
