So I upgraded a few months ago to s7 from my note 4. Held onto and unlocked the note 4 for overseas travel and have been using s7 for a few months. But I don't like the size and buggy nature of the phone. I do like some of the nuances though and would like to know if I can get my note 4 to look and operate similarly to the s7 without all the buggy features. AND can I go back to my note 4 if I don't like the s7 "upgrade"? Thanks for your help!
