Display Replacement
The C31 uses a fused LCD + digitizer assembly; repairs use a panel or display-with-frame service part. Seat with fresh adhesive and verify touch. The side fingerprint is unaffected.
Battery Replacement
Disconnect the battery connector and ease out the adhesive pull-tabs (or apply isopropyl alcohol). Fit the replacement without bending and re-seal.
Charging Port (Micro-USB) Repair
The micro-USB port is on a lower daughterboard — a very common, low-cost C31 repair. Clean first; replace the sub-board if charging fails.
Rear Cover Replacement
The plastic back is adhesive-mounted — heated, lifted and re-adhered. Very inexpensive.
