my husband and i both got the new samsung galaxy s7 edge and we use verizon. we managed to do the video call once and it was really cool to see each other, but then it has never worked since. it always says something like cant use this feature during call. i cant push the video button before i call either but in the setting videocall is enabled. i assume it means you have to pay for some extra feature to use this and they let us try it once for free or something??what would that feature be you have to add to your plan??how much??and can you then videocall others as well?i have a friend that got a LGV10 fi. or is this feature on the phone, somehow worked once, but not supported by verizon??
