Mini MM96 Iphone problem. - GSM-Forum

Hi. The phone works 100% on O2 UK (GSM 900 and 1800mHz) but has a problem using orange UK (1800mHz). In a phone call, the person I am speaking to can hear a loud buzzing sound all the time but you cant hear it on my end. It sounds like when you put a phone next to a speaker and you get interference.
Is this a common problem with china phones or do you think it's just my phone and I should get a replacement?
Thanks!

sorry for my bad english

Engineer mode *#20080808* -> AUDIO -> NORMAL -> microphone...
level 1-7 set from 160 to 170 (factory 180) or low

Hi thank you very much
I tried this: factory defult was 200 for ALL so I changed to:
vol0= 160
Vol1=161
vol2=162
vol3=163
vol4=165
vol5=166
vol6=168
vol7=170
I think maybe it is a LITTLE bit better but I can still hear the buzzing on the other end. do you think these values are good?

This menu also has "16 level setting": factory defult:
Max analog gain = 150
Step = 4

Do you think I should change anything here?
Thanks!

Ok I tried using smaller values which removes the buzzing but also removes my voice.

I dont think the mic is the problem because it works fine with a different band (O2). Is there a way to modify the TX signal or filter in engineer mode?
There is a RF test tool but I don't understand how to use it.
Also network settings but I also don't understand how to use it either.
