I have noticed a lag/delay when swiping up with the navigation gestures to go back home. Almost 70% of the time I have to swipe up twice just so that it can recognize the command. Similar think with the gestures to change between apps.
Yes I've noticed that as well and other users on XDA are reporting same issue. it is laggy when going back to the home and the recent app menu. when bringing down the status bar its same problem it is not smooth
Have you got Samsung Pay setup as that can cause a delay... you can switch the Samsung Pay swipe up on home option off in the Samsung Pay app settings. this help the lag for me
