Xolo A500s low microphone volume fix

If you are a Xolo A500S owner, then you might have noticed the low microphone volume on this handset. So think no more, just follow these simple steps and this problem will be fixed.

You can watch the video or follow the steps below.

The first step is to get in the “Engineer Mode” by pressing the following set of keys in the dialpad “*#*#3646633#*#*


The next step is to go to the “ Hardware Testing ” and select “ Audio “


Now select ” Normal Mode “


From the dropdown, select “ Mic “


Now we will increase the value to the highest possible number, which over here is “255” You can also select the level as “ level 6 ” , which will set the maximum value.


Now press “set” to apply, and then restart/reboot the handset.
