Hello all,
I have done my fair share of research on this topic. It seems like this may have something to do with a faulty batch of HTC Ones.
Description: Everything is working fine but then during a phone call, the other person is either unable to hear you or there is tremendous static. If you switch the mode to speakerphone everything works fine and as expected.
Solutions?:
People have suggested blowing into the mic hole -- didn't work for me
Replacement device -- a tad extreme but maybe necessary. What if the replacement is faulty too? Wasted time!
Other details:
There is a rumor that this has to do with faulty hardware due to HTC using different microphones..
There is also a rumor that it has something to do with HTC's Audio Cancelling software hidden deep in the Kernel/ROM/Baseband code. No one has been able to discover this yet, however.
There is another thread on here and VZW Support Agents have suggested a replacement device. I would like to open this discussion to talk about this and see if we can find a conclusive solution.
Thank you,
Patrick
