I've never tried one but if Apple wanted to do it you have to think it works. At least it'd be something new even if it is of marginal benefit.
Of course it works, it works on the S6E, the S6E+, the S7E & Note 7 as well as the Mate 9 Porsche Edition ...
But it working and individual personal preferences are different things.
My level of comfort, usability and in the end enjoyment of using last years Galaxy flagships was actually increased dramatically when I sold my S7E and bought the S7 instead. Sure aesthetically the E had the looks, but from every other perspective my day to day usage was only enhanced on the device as soon as I dumped the edge and went flat with small side bezels (and smaller device generally).
It's why with the S8 being 5.8 and 6.2" and both being contorted edged devices, I am not anyway near as excited by the prospect of its release, (I want to see it but no incentive current to buy) however had there been a similar smaller S8 flat device on the horizon, my ears would be more pricked.
There is always some compromise no matter what device you buy, it's where your personal preferences lay that dictate what device you will prefer enjoying in the end.
Samsung as seemingly eschewing the things I personally prefer in a device this year, and if Apple followed suit, I would have no interest either ...
