I will end up returning my note 7. I went from the note 3 to the note 7. I am on Verizon. My note 3 worked OK except at my office. I dropped a lot of calls there. Where I work is a known poor signal area by Verizon so I really need wifi calling as aback up. I also need good photos in low light. Finally I want wireless charging, but I don't mind buying a wireless back. Do you think the note 4 would work out for me?
