I have bought my A52 in the beginning of the year and since last one month if I receive call, caller cannot hear me but I can hear them properly. I did mic test it is fine but couldn't identify problems.
I had this issue started month ago about caller cannot here me when call first. However when trying second time they can. My phone app was samsung But I downloaded Google phone app and it work well for week and now again it started same problem with Google app too. Means it is problem with device.
I bought this A52s device in December 21 during Christmas.
