Also posted this out in the main One forum post on this topic, but anyone else notice reduced sound quality on calls with folks on older non-hd voice phones since the update?
Since the update, I have a constant low-level hissing in the background of calls to landlines or, for instance, to my parents older cell phone. On top of the hissing, the sound quality of the other folks voices sounds much more "tinny" than before. Otherwise, the update has been fine for me, stability and connection wise, but the reduction of call sound quality has been disappointing.
