Galaxy A12 (SM-A125) microphone repair 

Thanks for sharing the high-quality repair knowledge of microphone repair with everyone. Upvote for you!

Nice video, thanks! I just did it with my dad's phone as the mic was dead. It all went nice and smooth! By the way, don't say the tools provided are useless as they get destroyed after one single use... I would have used a knife otherwise, and we ALL know what happens when we do that, right? Uh, but yes, they do get destroyed after one single use -that was all I needed them for :)

Thanks for the video and for sharing your thoughts about the front camera along with other stuff. Your guide made installing the new board easy on my client's A12!

Great video. You saved my phone :-) Even with two left hands...

Hello, where do you order your parts? Please can you share a link? I would like to replace this board myself. Thanks for the instructions :)

Hi Andrew! This is a follow-up question to this video... Did replacing the the PCB solve the issue of the phone's mic not working? I have a similar problem in that the mic on my A12 seems to pick up sounds, but so faintly that the person I'm talking with can't hear me at all. But the phone works fine when I switch to speaker phone. I'm considering doing a PCB replacement like you showed in this video. It's been several months since you published this video. I don't know if you check comments on older videos so I'm not sure of a response. But here's hoping.

I guess that it's not necessary to remove the top portion if only changing the mic/ charge port.

Hello, where do you order your parts? I would like to swap board in mine.

Мне не помогла замена нижней платы. Я пропаял шлейф материнской платы и шлейф подключения нижней платы и заколосилось

Actually I am glad, as I have a A12 with the microphone not working after replacing the screen.

google voice for testing

I have an A12 and I suddenly have a microphone problem. Calls and voice recording is very muffled, but video recording is perfect. In this video you mention there are two mics??? I am stumped why video recording is crystal clear but phone is all muffled and I can't be heard unless I practically yell into the mic directly. Thanks!

This not always helps. These 12 Samsungs has issue from the main board where you have to run tiny wire down to mic especially when the olu second mic works only

Whats the cost of a new board and where do we order the board from?
