Right or left hand, general use. I have large hands. Took some getting use to since I've used two thick phones since original SGS, the screen is a bit healthy! I'm use to it now, with one pinky underneath, ring & middle on the sides and spine, and index fully supporting spine alone. The keyboard is swyped out & accurate again now! Picked up evo3d the other day, and OG evo last week they felt like alien technology, & 3d so narrow and heavy what the heck were they thinking. And I used that thing way to small to for comfortably in hand. Wider Is Better!
