Details:
In late 2018, the Chinese startup Royole released the first commercially available foldable smartphone with an OLED display, the Royole Flexpai. It featured a single 7.8-inch display that folds outwards, leaving the display exposed when folded.

The foldable smartphone runs features a single folding AMOLED display, comes with a 4,000 mAh and with a 16MP and 20MP dual-camera on its inner bezel. Aside from that, the phone also comes with a dual-SIM card setup, and features a fingerprint sensor.

Disrupting traditional concept of a smartphone, FlexPai can be used either folded or unfolded, giving it the portability of a smartphone plus the screen size of a high-definition tablet.

FlexPai's screen is virtually unbreakable and extremely durable passing tests where the screen has been bent over 200,000 times. Its screen provides fantastic color range, high contrast, wide angle, and high-resolution for outstanding picture quality.

Less is More

Always Take A Selfie
Dual View Camera Mode
In Dual View Camera Mode, the object of your photo is visible from each screen when folded. Whether it's a selfie, portrait or candid photo, you can use FlexPai's screens to make sure the pose is perfect before the image is captured. No need for multiple shots by getting it right the first time.
