Huge quality issues on my phone on both ends. I hear constant digital compression sounds in the earpiece, hissing, crackling, muffling that comes and goes and modulates with the persons voice and pauses. Sounds like crap DAC or DSP artifacts. Its unbearable.
My voice is muffled to the caller, ive done recordings and voicemails and it sounds like I am talking over a NASA sat comm link, you know the transmisssions from astornauts, how they have a disconnected sound about them. bad sampling rate or frequency clipping, its horrible and doesnt even sound like my voice, its missing entire high ends of the frequencies as if i reencoded my voice down to some of the lowest bitrates for speech.
My HTC had amazing call quality, this is horrendous. Its sad that I cannot keep this phone because of this issue. Everything else about this phone is incredible. But it is still a phone.
