Strange voice while calling 
Hi! [again :]
Its still everything about my lucky nokia 3210 ;]
I've bought it from my friend on lower price because i knew that it had a problem with robot-like voice while call.
I thought that flashing it would help, but it didn't help at all...
- when I start a call (in/out-coming) the voice became
misunderstandingly strange ) [sorry for that englishlike words]
- there is a RXQUAL_FULL indicator in NetMonitor which represents the percentage of mistakes in voice decoding (??) and when the voice is scrambled it shows value of 5 to 7 ( very big interferences )
- voice becomes clear and understood when I squeeze it in some way or when i detach back case of phone. [ but not in 100% ]
What can help ?
some people say to reset it to full factory ... - I don't belive in that.
other say to heat up the IC's on PCB with soldering tool because of oxidation of solder in BGA connections ( rather strange and harmfull )
People aren't serios enough to get them in that way...
