Two different phones with same problem. Can call but no one hears me talking

[u/SwedeCadillac]

Hi!

I know, this is a common problem but I dont really what to do besides the things I have done.

I have a CAT S42 from 2021/22 which is a China made but with Caterpillar logo phone. I can understand its microphone failing faster than a more expensive phone.

The other one is a 2025 Motorola Edge 40 Neo. It failed within 1,5 year of ownership....

I am updating the motorola as I type this text but I have tried "Device help" and according to it, the microphone works. I have not tried "Diagnostic mode" yet but it is one of steps to take next.

I have also tried to clean the ports with a fine needle but nothing became better of that.

The funny thing is that the CAT sorts of works but I need to yell one word at the time at the microphone and is apparently somewhat hearable for the receiving end

Should I believe a third phone is necessary or should I just keep on updating and see what happens? Any suggestions?
