My microphones randomly stop working

[Kamen Kalchev]

Hi there!
My phone is Xiaomi Mi A2 Lite. It was upgraded to Android 10 about a month ago. It was working fine 2-3 weeks after the upgrade so I'm not sure if it's related but last week my both microphones randomly stop working. Usually they work several hours after I restart my phone but at some moment they switch off completely - no matter if it's for calls, google assistant, test apps, sound meters - they hear nothing. Still some programs seem to wake them up - like Skype's echo and after that they work for some time but later they switch off again. Shaking, knocking the phone doesn't seem to make them work so it looks like a software problem (I haven't installed anything before the problem occurred) but what exactly and how can it be fixed?

Welcome to Android Central! See if it still happens in Safe Mode: https://www.getdroidtips.com/boot-xiaomi-mi-a2-lite-into-mode/. (Hopefully these steps work -- some Chinese manufacturers don't allow users to boot into Safe Mode for unclear reasons.)

Thanks for answering! I tried safe mode, it works but I can't conclude anything because as I said the problem usually occurs only several hours after restart and it's uncomfortable to stay all day long in safe mode. I consider factory reset too but if there is a better idea I would be grateful

Unfortunately, that will be hard to pinpoint without any suspected culprits to start with. It's possible that some app you had installed is not playing nice with the Android 10 update, but there's no easy way to figure that out.:-\

That's what I would like to know - what could be suspected. I have granted access to the microphone only to the most used programs like the phone, google and some communication apps but not sure if an app without permission could still cause the problem, a system bug or it still could be the hardware

Any app can be suspected. A developer can leave an undetected bug in the app.

Try putting the phone into safe mode when you go to sleep (plug in the charger, just to be safe). See if it happens again when you wake up.

Those type of issues are hard to find ,happening several hours later.
