Bad call quality after change of power flex
I changed some power flex from iPhone 5 and after the repair the call quality was very bad.
If i doing a longer call the calling partner tells me he can not hear me good. I tried it out and the voice coming from my iPhone sounds like a computer or somebody is talking into a tin. Maybe a weaweawea. But not all time.
Anybody knows an idea?
Is this a good question?
