Is anyone else having this problem? Verizon rep set my S6 edge up at the store and used a ridiculous amount of data doing so. I didn't realize until later on when I got home that while the phone is connected to wifi it is also using 4G. The wifi arrows move and the 4G is lit and the arrows underneath also move and waste my data. Verizon could not find the answer. Technical support had me shut off every option that could be causing this to happen -- download booster, smartswitch etc and nothing worked. My only option is to go into settings and manually shut off the mobile data when I am on wifi which is inconvenient and annoying and costly if I forget. The phone was replaced and deemed defective by Verizon and replaced with another. The new edge does the same thing and Verizon and Samsung can not give me an answer as to why. Any thoughts?
