Wi-Fi and Bluetooth connectivity options are also confirmed, as the device packs a rather hefty 1,500mAh battery. Not only that, there seems to be an unknown button that is located right at the top of its left side which currently the Galaxy S II does not possess. It is also smaller compared to the Galaxy S II’s power button, so chances are it might end up as a kind of switch or slider.
Do you think the slider is somewhat like the Nintendo 3DS’ capability to adjust just how much “3D” you want to view? That’s stretching it somewhat, but you can never rule out such possibilities until an official word from Samsung is released.
