Call quality - going silent from the other end?
I have the UK unlocked HTC One, currently running Android Revolution HD 12.2. I've been experiencing really poor call quality - as well as the person I am calling being very quiet, apparently from the other end I simply 'cut out' with some regularity. This happens whether or not there is a case on the phone (although neither of my cases blocks the hole on the back for noise cancelling.) Today, for example, I had to call one person three times before they could hear me, but I also cut out mid conversation at points.
This is getting seriously irritating. Is there any way that I can prove that this is happening - any mic tests etc that can be done? Or is my only chance to go back to stock, take it into the shop, and hope they can replicate the issue?
Cheers for any advice!
