I have two issues on the S7 in which I believe should have solutions considering they aren't issues on my dated S4. 1. Seamless transition from WiFi and 4G. On my S4 It would have a WiFi preference but before I would lose my connection with WiFi but it was about to, it would switch to 4G seamlessly so that I wouldn't notice a break in connection. I would think that the S7 should be capable of this considering the S4 is. 2. Back button vs. Back arrow button in the message app. On the S7 if I press the bottom right back button, or if I hit the back arrow button on the top left of the message app, both will go back to whatever previous page I was on. This means if I go from a different app to an open message, I can't single button press to get back to the message home page to access other messages. On my S4, hitting the bottom right back button goes back to whatever page I was last on, and the top left back arrow in the app it would go back to my message home page so I can access other messages with a single button press. Are there simple ways of correcting these?
