mobile

Hi
I have marked that many things are different in S6 and many many features are missing
1) Auto brightness gets disable on its own
2 ) Edge notification getting disabled
3) Open background tab opting missing
4) Switching between chrome tabs needs left hard key
5) Apps are crashing
6) Annoying Mobile data disable popup window!(with no option to disable it)
7) Long pressing Mobile data options opens up data uses rather than network settings!
8) Quick view can't be expanded by dragging it with two fingures!
9) Syncing is not good
10) people can hear me well on phone.
11) No guest mode!
I get more of a feel that I am using iPhone than S6! Many user settings are missing
