Samsung should bring back the Hand Gesture feature which was on Samsung Galaxy Note 2. With this feature a simple Hand movement over the phone without touching the phone shows the alerts on notifications on lockscreen.
Also Samsung should bring the curve screens which was available on the earlier Note Series.
I think the second point is already valid, because many people nowadays are complaining of HAVING a curved screen. And secondly, i just think it would be lame to add hand gestures. Just think if you were to read the notifications in a public place. Would you waive your hand or would you just simply double tap to read the notifications? Plus there are also options for always on display which shows the notifications even if the phone is off by showing only the apps of the notifications recieved.
