+ Battery cover more stable than the factory settings. The plastic is
thick and has at the top of a kind of honeycomb structure.
+ Runtime better according to the higher capacity.
+ Camera is now protected 'embedded'.
+ Device still fits easily in my Bugatti leather case.
+ The Samsung car holder, the device takes on yet.
+ To me better haptics.
In short: Why not so? Well just to give the impression of the thinnest smartphones (For me the thickest part defines the thickness of the device, that was window dressing).
I am completely satisfied!
