Smart Stay: The phone tracks your eyes, so as long as you're looking at it, the display won't dim or turn off. Direct Call: If you've got a contact on your screen, there's no need to hit call: simply hold the device up to your face and the number will be dialed automatically. Smart Alert: Burst shot and best photo The 8MP camera now offers a 20-shot burst mode and will choose the best photo for you. Photos are now possible at the same time as video filming. Unlocked cell phones are compatible with GSM carriers such as AT&T and T-Mobile, but are not compatible with CDMA carriers such as Verizon and Sprint.
