Here is the list of most basic features that Samsung think is not needed to its wide customer base yet available in almost all android phones:
1) No native App Lock : this feature not only help lock apps but also hide content of notification that comes on locked apps. Secure folder is just a lame attempt to cover up and it fails miserably.
2) Can't search full name on phone keypad, most basic way to dial anyone's number is to search there name on keypad and yet some how samsung things its irrelevant too.
3) No option for network speed to be shown on samsung devices.
4) No gestures to turn on the flashlight. (Like: Drawing Circle on lock screen to turn on flashlight)
5) swipe to screenshot doesn't work in most cases, 3 finger swipe is so easy to use.
6) Can't mute calls while dailing.
