When the gestures are enabled with vibration means that when you swipe up for the opened apps and there is a little vibration, this should mean that the apps will show which are previously opened.
With this new update, when the vibration takes place it doesn't show the opened apps rather the swipe gesture has to be kept to that position longer than the first beta roll out. This issue needs to be sorted out.
Secondly, when an app is opened for example galaxy store and if you'd like to move onto the other apps, you could swipe left of right to switch ever so quickly and this was one of the best gestures. Again, with this new update this feature has now disappeared and it is sad to see it go. This feature shouldn't have been removed and should be brought back asap.
Also, this is for the camera suggestion, cab samsung make all the cameras of the galaxy s11 have consistent colour accuracy across all lens. This will make all the videos and photos look better and make it better especially for video to be better than iPhone colour consistency across their cameras.
