Important Repair Notes
- Check Your Model Variant: Ensure you are ordering the exact part matching your device variant (the 4G version utilizes a different internal board design compared to the 5G version).
- Component Testing: Replacement sub-boards usually arrive fully tested. However, it is highly recommended to temporarily plug in the ribbon cable to test both charging and microphone functionality before applying adhesive to seal the back cover.
- Installation: Since the process involves removing the phone’s back glass panel and delicate internal ribbons, it is strongly recommended to have a professional technician install the part to avoid accidental hardware damage.
