Q: Does the charging port board include the microphone on Redmi Note 7 / Note 7 Pro?
A: Yes. On both Xiaomi Redmi Note 7 and Redmi Note 7 Pro, the charging port board comes with the primary microphone integrated into the same module. If your microphone is not working during calls or voice recordings, replacing the charging port board often resolves the issue.
Troubleshooting (After The Repair)
Q: The phone is still not charging after replacing the charging port board. What should I check?
A: First, confirm that the main flex cable and antenna connector are securely attached to the charging port board. A loose connection can prevent charging. Also, inspect the battery connector to ensure it is properly seated. Try using a different charging cable and adapter to rule out external issues.
Q: The microphone does not work after reassembly. What could be wrong?
A: The microphone is part of the charging port board. If it is not working, the board may not be seated correctly, or the flex cable connection may be loose. Reopen the phone and reseat the charging port board and its connectors carefully.
Q: The phone only charges at a certain angle. Why does this happen?
A: This usually indicates that the charging port board is not aligned correctly or the connector is not fully secured. Remove the board, reposition it properly in the frame, and tighten the screw before reassembling.
Q: The back cover feels loose after repair. How can I fix it?
A: Clean off any old adhesive residue and apply fresh B7000 glue or double-sided adhesive around the edges. Use bonding clips or rubber bands to apply even pressure while the adhesive sets.
Q: The phone does not turn on after the repair. What should I do?
A: Check that the battery connector is properly connected and that no flex cables were accidentally left unplugged. Connect the charger and leave the phone charging for 10–15 minutes before trying to power it on.
