Meet the Nuu B40 5G, an affordable dual‑screen smartphone you can actually buy in the US. It takes the eye‑catching idea of a rear display and brings it to a price point that’s far easier on the wallet. The tiny “Vista Display” on the back isn’t just for show—it’s a practical, glanceable screen that helps you check essentials, control media, and even frame selfies without waking the main display, which can help save battery and reduce unnecessary screen time.
Up front, the Nuu B40 5G features a 6.7‑inch FHD+ curved AMOLED with a smooth 120Hz refresh rate and up to 1,100 nits peak brightness for comfortable outdoor visibility. On the back, the 1.6‑inch AMOLED Vista Display (228 × 460, up to 500 nits) sits beside the camera island, doubling as a mini dashboard and camera tool.
What the rear Vista Display can do:
– Always‑on time and date
– Music and playback controls
– Charging status at a glance
– Call and message previews
– Step count
– Camera viewfinder and shutter, perfect for rear‑camera selfies
Under the hood, it’s powered by MediaTek’s Dimensity 7025 with 8GB of RAM and 256GB of storage. There’s no microSD slot, so plan your storage accordingly. For photos and video, you get a 64MP main camera paired with a 2MP macro, plus a 16MP selfie camera. The camera app supports simultaneous front-and-rear video recording, a Pro mode, and RAW capture for those who like to edit their shots.
Connectivity and extras include dual‑band Wi‑Fi, Bluetooth 5.2, dual SIM support, an in‑display fingerprint scanner, and a USB‑C port (USB 2.0). You won’t find NFC or a headphone jack here. A 5,000mAh battery keeps things running, and 33W fast wired charging gets you back up quickly. The phone ships with Android 15 out of the box.
