I'm having poor signal quality from service provider(the signal for recieving calls, messages etc.)
When I check from "about device" section, it usually says around -110 dbm and 2 asu.
I have no problems connecting internet via wifi( my home's modem, not mobile data)
I have given the phone to a technician for repair but it's still not fixed.
I opened the case and checked antenna(which I'm guessing, was replaced by the technician, so it's most probably pretty new), which looked like okay.
I usually recive only 1-2 bars and rarely 4 bars of signal quality.
What might be the reason(s)?
