After having my S7 Edge for about a month, I've noticed I lose 4g/data signal often. Sometimes it drops down to 3g or 1x, and sometimes it's just completely gone. I notice it most at work & while there are some part of the building that have weak cell signal, it's never been the entire building. My office is generally ok & my old phone had no issues with data signals in the same places. (Previous phone was Droid Turbo.) Anybody else experiencing data service issues?
