Microphone is muting during calls
Hi,
About a month after the purchase, I began having a problem. My microphone was muting during the call without pressing the icon. Moreover, the icon didn't show that the microphone was muted. Later I noticed that this problem occurs if I'm silent and listening to the other person. The microphone then unmutes 3-5 seconds after I start speaking and later mutes again during the silence. Then, maybe after the new update, the muting stopped, but after the latest update, I'm having the same problem during every call.
I heard other people have the same trouble, so I would like to know how I can fix this issue.
Thank you for your response.
