Common Symptoms Requiring Replacement
You most likely need to swap out this charging flex board if your device exhibits any of the following issues:
- No Charging Indication: The phone fails to recognize the charger entirely or require positioning the cable at precise angles to detect power.
- Fake/Slow Charging: The charging logo appears on-screen, but the actual battery percentage drops or fails to increase over time.
- Microphone Faults: The caller on the other end cannot hear you, as the primary microphone is integrated into this exact sub-board.
Installation Tips
If you are planning to perform a DIY replacement, remember to disconnect the phone’s battery connector first to mitigate short-circuiting risks. Take extra care when prying off the tiny RF antenna wire attached to the bottom corner of the old sub-board so it does not snap.
