- a shitload of unwanted stuff (Samsung Services, Samsung Applications) that randomly update themselves
- The 'resize window' feature. If you've seen people using a Note you might've noticed that they had two apps open at the same time for example. The rather small (this is a 'pro', btw) S6E has the same feature, but it is pointless. Worse, I constantly, daily, activate it in error. Right handed, swipe with the thumb to open the notifications. This always ends up (try it) being a diagonal swipe for me, from top-right to bottom-left. Diagonal swipes like that activate the 'shrink current window' feature.
