Frequently Asked Questions

Does this charging board fit the Galaxy A12 Nacho (A127) version?
No. This board is exclusively intended for the Galaxy A12 with MediaTek processor (SM-A125). The A127 version uses a different sub-board revision.

Does replacing this part solve microphone call issues?
Yes, if the fault is caused by the lower microphone integrated into this secondary board. If the failure lies in the main board audio line, replacement will not resolve it — verify diagnosis before intervention.
