Hi all,. So I ordered an S7 international version to use on AT&T because I wanted root and the supposed better battery life. I have a few questions about AT&T specific features though and was wondering if anyone had answers. 1. Video Call. My dad has an S7 Edge and we tried video calling but ran into problems. If he called me it would say that I am "not available for Video call". However on my phone the video call button is there and if I call him i rings for 1-2 seconds and then abruptly ends. Is video calling supported on the international version of the S7? 2. Same thing as above but with HD Voice. I am now wondering if I don't support HD Voice as calls have not seemed to be crystal clear. Does anyone else have experience with the international version on AT&T? if so what is your experience? Besides that I absolutely love the phone.
