I got a Lumia 1020 from HK recently. everything was working fine till I got the black update.
When the phone is on full volume like 10/10 for calls and 30/30 for general audio, the speaker volume just drops to almost 0. For eg if I am on a call when on the road I have the phone running on speaker, it starts off with full volume and while it is running it just drops to inaudible. If I turn the speaker off and then back on again the same issue continues. I have checked the phone volume using the buttons and it shows 10/10 regardless of wether the speaker is on or off likewise with audio from apps or just audio files or videos. Now I have tried all the resets I can think of nothing fixes it. Should I flash my phone from HK CV to AU CV? it is a RM875 model and running on black update.
The firmware version is 3051.40000.1345.1003 and the AU version is 3051.40000.1345.1006.
Anyway I can find what is the difference between these to versions?
will it be a problem if the model number is off a black or yellow phone instead of white if I have to end up flashing the phone?
