Earpiece functionality breaks after Oreo update

[ping24]

Hi All,
Of late I've updated my 3T to Oreo and once the upgrade is done I am unable to make calls, receive calls since the voice of my end is totally mute at the other end. It was all working fine till I had the last update but after this upgrade the earpiece functionality has totally become sort of unstable. I am able to listen to Music but when I call, the other end person is unable to hear my voice.

Is there any fix that I need to apply to fix this problem? Its very annoying to have the earpiece functionality being broken.

Please help!

Earpiece? I think you mean the microphone is not working. I'm not sure if you mean by a third-party earphone, or if you're talking about your in-built mic.
If it is your inbuilt mic, try flashing a ROM. Preferably N20s or Cardinal Xtended. If that does not fix it, I recommend you send the device in for an RMA.

If it was the update from OOS 4.5.1 to 5.0, I suggest you to do factory reset (which is recommended when upgrading Android version).
