========================================
Most of people are complaining on how they hear me when making a call. I hear them fine but they hear me very poorly and interrupting. What is interesting - using a bluetooth headset fixes the problem. So it cannot be network related issue. I have tried updating, downloading a different Phone app - none of this work. I will try removing a case because in is covering antenna bands on the side but since there are no problems when using a bluetooth headset - I do not think it will fix anything.

Hey @cyraxaz,

I had forwarded the issue to R&D, and the team requires the following information from your end-

1. Which network operator do you use?
2. When did you first notice this issue? (EX: After some FOTA update )
3. Does the issue occur during the start of the call, or in the middle of a conversation
4. Does this happen while calling through third-party apps too? (EX: Line, Whatsapp)?

Aside from the above queries, can you please share a log file, as it'll help determine what triggers the issue?

Hi All,

i have the same mic issues as desribed above. And it seems that I am not alone.... see the link below:

I could hear people just fine, but the other complained that they heard me occasionally with crackling noises & in a low quality. When I use bloototh ear buds  the issue disappears. I tested my mic by recording my voice and here the mic is working correctly. The issue appears only during a call. The issue exists since I bought the phone and any of the updates did not resolve it yet. I did not try Whats up or third-party apps.

I use Android 13 with the system update 33.0804.2060.88.
