From GSM Arena (specs in my bold emphasis):
The vivo X Fold has a 6.53-inch outer AMOLED display and a folding 8.03-inch 1800x2200px LTPO2 inner AMOLED E5 display. Both operate at up to 120Hz and are HDR10+ ready, with the main one able to slow down all the day to 1Hz.
The folding display uses SCHOTT UTG (ultra thin glass, Schott manufactures Samsung's UTG). The display has Display Mate's A+ recommendation. There are two in-display fingerprint scanners on the vivo X Fold. Both are ultrasonic scanners, not optical ones.
The hinge is an aircraft-grade floating wing hinge. It allows the vivo X Fold to close flat, and to stay open at an angles between 60 and 120 degrees.
Powering the vivo X Fold is a flagship Snapdragon 8 Gen 1 chip with 12GB of RAM. There's a 4,600mAh battery that can recharge rapidly. You get 66W through the cable - that tops up the battery in 37 minutes. The vivo X Fold can also wirelessly charge at up to 50W and reverse wirelessly charge at 10W at the same time.
The cameras are flagship-grade, especially when compared to the Samsung Galaxy foldables. There's a 50MP f/1.8 main camera with OIS in front of a 1/1.57-inch Samsung GN5 sensor, a 12MP f/2.4 2x (47mm) zoom camera, a 5x periscope zoom camera (with 60x digital zoom), and a 48MP f/2.2 114-degree ultrawide. The Zeiss branding on the camera module further indicates vivo means business with these imagers. Zeiss modes include Texture Portrait, Motion Capture 3.0, Zeiss Super Night Scene, Zeiss Nature Color and more.
As usual, there's a super arty promo video:
A lot will depend on just how good the new hinge is - the aim is to present no discernible 'crease', but I'm sceptical! A lot also depends on the price in the West, assuming this gets here at all. Current Chinese prices equate to £1300 or so, but this might all change once made into a 'world' edition, etc.
There's also a 'making of' video, which is fascinating but sadly all in Chinese. Still, you'll get the gist:
