Actually that's pretty much what the reps for LG said when they were explaining why the LG G6 is constructed the way it is. They explained there was a limited amount of space to work with and one of their decisions (I can't remember what it was) was based on wishing to avoid having to stick the fingerprint sensor higher up on near the camera.They must have a reason.
Maybe having the fingerprint sensor, camera module and flash/HR next to each other creates a lot more space underneath for internals/battery that are already getting squeezed due to smaller bezels.
(I'm not saying that reason makes sense, but...)
The S8 is definitely a phone I would have to see in person and hold in my hand to fall in love with. I'm just not feeling it based on photos like I did for the S7/S7 Edge and Note 7. I know the fit and finish will be gorgeous. I'm just not feeling the overwhelming roundness of it all, based on the photos.
I think it will probably be very nice to hold, though.
My S7 and my S7 Edge are works of art. I never get tired of looking at them.
