Hi everyone.
Since a lot of us have been complaining on Lumia's 1020 low volume during GSM calls even if it is set on 10/10, i think i might provide a possible fix which i have tried today and there is significant improvement.
First of all...in earpiece/headphone (top middle) inside we have a piece of black rubber.
If you take your SIM tray clip and press it against that rubber you will see that it goes inside and goes back again (somekind of protection against dirt and grease).
OK, the actual first thing i've done was that i've took the common toothbrush, and i pressed it hardly against earpiece like you are cleaning it. Do that for 30 seconds (rub it / clean it).
Then take the SIM tray clip or paper clip and press it against that rubber inside and blow a little bit of air inside (mouth blow).
It worked for me and now acctually when making GSM calls i can remove the phone from head and i can hear the other side just fine, not like it's on speaker but an improvement.
I hope it will help you.
Reminder:
I am on WP 8.1 DvP, factory unlocked L1020 bought in Germany with RM-875_eu_hungary_298.
I live in Croatia and my operator is VIPnet Croatia.
