When phone maker Oppo says that the Oppo Find X is almost all screen, it really means it. The Android handset is arresting to look at, mostly because its 6.4-inch display really does stretch across the entire phone face -- there isn't even a camera for taking selfies. Or rather, there is, but you won't see it until you open it like a push-pop.

The Oppo Find X (announced Tuesday) has a screen that stretches from the very top of the phone, wraps around the sides and goes almost to the very bottom (the phone has a thin bottom bezel, aka a "chin"). The screen-to-body ratio is 93.8 percent, so when you're looking at the front of the phone, you're almost always looking at the display.
