Are you talking about developer options or system tuner? Anyway, what settings do you want to change? I am not aware of call settings there.

Hi @ADevotedFan,

As far as I know there is no setting called "Engineering Mode". Could you tell us a little more about what you need help with?

If there is low volume for the counterpart during calls, try testing the microphone in Diagnostics. Go to Settings > About phone > Test > Microphone. Are you experiencing the same thing here as well?

Yes I have done the test about 5 times and the mic is really quite. I tested my old Xperia sp and the difference is like day and night. I dont think it is a hardware problem because this phenomenon started when I updated to marshmallow latest build.Plz give me ur opinion on this.

Hi there, you could try with *#*#service#*#* there you will find more hardware related tests, if the tests pass as successful and you are satisfied with the voice volume you record, then you may have a fault in the OS and maybe a software repair can fix it for you. Also, did you try changing different calls audio settings?

OK guys ty for the tips I did an OS repair with flashtool and it worked fantastic. Sony really though needs to fix bugs like that.
