Problem with the microphone in calls

[Sebasbta]

Hello, I have problems with the microphone of my cell phone, calls sometimes does not work, but if the speaker or headphones work. I took it as a guarantee a few days ago and they solved the problem, but today again it presents the same problem again.

I see that in the forums several people have the same problem and SONY does not give a real solution to this, this disappoints me of SONY.

Hi @Sebasbta, I am sorry to hear about this, let me see if i can be of any help here! 

As you might know, the XA1 Ultra has a total of two microphones. A main microphone located at the bottom of the display used in calls and a secondary microphone used for other recordings such as video and calls on loudspeaker. To see where these microphones are located, please see item 4 and item 11 the overview of XA1 Ultra.

Firstly I suggest that if you have a cover, case or protective film, that you try to remove it and see if the microphone quality persists. another thing that you can check is so that there is no water or dust blocking the microphone or the area around the microphone.

I would also suggest that you use the Tests feature in the Support app to carry out a quick test to check that the loudspeaker is working properly. In order to do this, fins and tap Settings > Support > Xperia tests > Microphone.

Another thing that you can try is to reboot your phone in Safe mode. All apps downloaded from Play store is deactivated in safe mode and by doing this you can see if there is a downloaded app that is causing this. For more information and instructions on how to enter safe mode, please click here. 

If none of these measures work to improve the sound from the microphone I would suggest that you try to perform a software repair using a computer and Xperia Companion. Please note though that a software repair will erase all user data, so remember to do a backup of your user data first. 

Try these measures and let me know how it goes!
