Hi everybody,
I recently bought an used phone in Spain. The phone arrived with android 9 (I don't remember exactly which version) and I checked all the functions with the service menu. The only thing that worked badly was the secondary microphone, which had a recording volume extremely low. I thought it could be fine anyway. So I updated the phone OTA, then I did a companion restore (to 52.1.A.0.618). At that point I put the sim, and made the first whatsapp call. Everything was fine at the beginning but at the end of the call, the speaker started croaking (badly). From the service test I identified the bottom speaker (the one called right) as the malfunctioned one. So, thinking it was the fault of the update I downgraded to Android 9, following the guide on that forum, but it didn't work. Then I updated again with flashtool to Android 10, first with the Italian firmware (to 52.1.A.0.672), then with the Iberian firmware (to 52.1.A.0.618). But in both cases even the microphone no longer works correctly. If I record video, the microphone works fine, while if I make calls, the microphone works only if I put it on loud speaker. In the normal mode the interlocutor hears me but at a very low volume. Same problem from the service test. The microphone works, but only if I speak attached to the microphone hole. I tried to clean with a toothbrush, but problem still there. The phone has no cover.
Any one faced similar problems?
Fixed by replacing them. Now facing touch screen issue (updated to 52.1.A.0.672)
