Lenovo K4 Note - Audio Receiver issue

2019-09-30, 12:36 PM

My 3 years old K4 Note just experience problems below.

- In call mic not work. The other party cannot hear my voice. The problem disappear when I switch to speakerphone.

- Something very wrong occur when I plug headset/headphone in, no sound in and out of the headset. Test using Lenovo help diagnostics: speaker passed, mic passed, audio jack passed, receiver failed. Test using ####1111#: audio receiver and headphone test failed (not able to test mic123 since the audio receiver/headphone already failed). The test is like ------v----v--v (the v is when I hear sound through my headphone and - is static noise).

 

FYI:

- I use one headset and one headphone and it work fine on the other phone.

- Test the audio using bluetooth headset and it work fine, no problem at all.

- Maybe it affected, the night before I accidently press uninstall to system app "Device Service" and revert it to factory default.

- Testing in safe mode has no effect, the problems still occur.

- I keep try to avoid factory reset because there are so many things to make up again and will do it as last option.

 

Thanks you so much for any suggestion and/or solution ?

Hi lordlugo,

 

Thanks for posting. I appreciate those things you've tried. This is odd, so in your case, the microphone isn't working on calls when not in speaker mode. Can you replicate it with third-party apps like Messenger? 

 

I'm not sure what you mean by uninstalling system app device service? Can you elaborate it? Thanks.

 

Best regards,
Rich
