Anche io ho questo problema (14)

Several days ago both of the microphones on my Galaxy A12 failed during phone calls and voice recordings using the messaging app.  At best I could hear, and others I was talking to could hear, very faint sounds surrounded by static.

However....

When I use the video feature on the Camera app, both microphones record my voice clearly, without any static.

I am completely baffled as to the nature of this problem.  Is it bad hardware?  Bad software?

I tried a full factory reset and every other bit of advice related to the microphones, but the problem remains consistent.

The mics do not work when I make a phone call; they do work when I record a video.

Thanks in advance!

Same issue here, I make a phone call I can hear them, they cannot hear me. If I use speaker phone they can hear me.

The board that has the microphone and charge port is faulty.  I had exactly the same problem and fixed it by replacing the board.  This is similar to what I ordered: Pour Samsung Galaxy A12 A125F Port de Charge Dock Connecteur Casque Jack & Micro | eBay.  Look at the process for replacing the board.  Hardest part was spludging the case open.  Bing Videos .  Also need a spludge kit like this 22 in 1 Mobile Phone Repair Tools Kit Set Spudger Pry Opening Tool Screwdriver | eBay

You have to replace the lower mic.

This is a known DEFECT from Samsung!

Sorry to hear that...again another failed board.

You will need to have the mic board replaces.  It is not hard to change.

April 2025 and my husbands A12 has the same problem now. Can speak on a call through the speaker on normal calls only. Ok on videoing. Tried all the fixers bar factory set, good job really as it doesn't appear to work. Another way to get you to buy a new phone after a few years..

Had this problem with mic1 not working. Was told by my phone supplier that it was a hardware problem. Searched for A12 mic repair on google and found a video explaining how to do it. Bought a new mic board from ebay for £5. This also included the charging port. Replaced as per the video and the mic is now working ok. Most difficult part was removing the back from the phone.

There are two boards available, 125F and 127F. Check which you need under settings, about phone, model number.

Make sure that you remove the sim card and carrier before trying to take off the back.
