To me, when I am pushing D-Pad left, and home/end, I feel like I am pushing the same phyiscal button...
So, it seems that we only have four physical buttons on the bottom.
D-pad up button, d-pad down button, home/send/d-pad left button, and the back/end/d-pad right button.
Seriously, I think they are the same button, but it uses the capacitive feature to tell WHERE on the button you are pushing. That's how it determines whether you mean to move right/end/go back/etc...
yup, I am right. I just messed with it some more. If you put your thumb over the back/end key, covering both, and push in.. it thinks you are hitting d-pad right.
Interesting idea, but I have had several times where the phone thought I meant to do something else... like many times I have to hit end a few times, just because it thought I hit right or back...
Just an interesting thing to think about!
