As soon as I flashed 2 people called and said I sounded a little muffled but could still understand me. I have 100 MODs via xposed (which shouldnt matter) but i went ahead and reflashed to try it without Mods and still same. So reflashed and wiped everything again and the 1 person I did call they didnt say anything about it so.
Yes im on lastest everything. And came from the OTA where no one said anything about it being unclear.
And no luck with my getting wifi calling to work. (dont ever use it) but just wanted to see if anyone else got it working.
