How long ago did you update the phone? I hope this problem is not from the update because a lot of us got an update on the S7 edge a while back and had this problem til that sent out another update. One of the things that you maybe able to try is go into settings - backup and reset..... then go down to reset network settings. This will clear out all the settings you had for network and you will have to put in all your passwords again but this did help some that were having this problem
I believe it was this Monday. I'm a heavy user when home so wifi is key to staying within my data package. Two updates ago my gallery app started malfunctioning so I used goggle photos instead and that worked. It was fixed in the following update. Now this treat in the last. Quite frustrating. So guess I will have too wait until they come up w a fix in a new update. Looking forward to having to monitor my data now when I shouldn't have to. I will try your advice on resetting. Thx for your response.
