I hate this S7 Edge so much, can't wait to replace it with the Note 8. But I don't know if my problem is specifically due to this model. For months now I have been mostly dependent on setting up a hotspot on my old phone in order to do basic stuff on this one. Where's my 4G? I almost never have an icon for it, and it's very aggravating not being able to depend on my phone when I'm traveling and need to find a gas station or something. I have been a T-Mobile subscriber since I got my first phone umpteen years ago. Do I need to call them up and give them hell or what? Anybody got any insight?
