Common Symptoms That Confirm You Need This Part
- The device does not receive power or fails to trigger fast charging.
- The micro-USB data cable connection feels loose, easily disconnects, or requires bending to work.
- The phone charges, but the microphone fails to transmit your voice during phone calls.
Repair and Installation Tips
- Verify Your Model: Ensure your device matches the Tecno Pouvoir 4 (LC7) or Pouvoir 4 Pro (LC8) tag, as other Tecno model flex bands utilize different pin configurations.
- Handle with Care: The main logic ribbon and lower sub-board connections are incredibly thin. Avoid bending, pulling, or using sharp metal tools directly near the connectors.
- Dry Testing: Always plug the module into the main board flex ribbon to test charging before sealing or gluing down the phone’s back adhesive.
