This is getting worse for me. I got to thinking that it might be because I'm using Google Voice? Anyone NOT using GV have this issue (apologies if I missed that in the previous posts)?
Also, I have been switching to Talkatone/GV for long calls and although the quality is a bit less, it doesn't cut out...ever (and I don't even use any minutes). Only downside is that it seems to require 4G unless I'm around wireless, so just have to be aware of that...last month while I was testing, I used about .2G data and <10mins calling...I'm considering just dropping my plan and getting a mifi, lol.
