I'm getting a slight sense of deja vu from seeing this phone.
Sent from my Sony Xperia
In my opinion, the unique position of the power button on a groove can mean two things...
1. The power button is also resistive touch.
2. If the power button is physical, then it may house a fingerprint sensor. If this is the case then I think this might be the most ingenious way of integrating fingerprint security in smartphones because our thumb rests naturally on the right side of the phone... (Except for lefty users of course)...
Personally, I'm hoping the later is true, it could definitely mean something new in terms of smartphones and fingerprint readers..
It's really nice to see more company's launch 6" devices!! Plenty of options for folks who like it big!!
