Frequently Asked Questions

No. This interconnection flex has the specific length and pinout for the Samsung Galaxy S22 5G (SM-S901) chassis, and is not interchangeable with Plus or Ultra versions.

Yes, provided the fault lies in current transport between the charging sub-board and the mainboard; if the USB-C port is physically broken, the repair may require the sub-board.
