display
8.1 inches, dual AMOLED screensWhen unfolded you get two 5.6-inch AMOLED panes side-by-side; folded, one 5.6-inch display for one-handed use, both at 401 ppi.
performance
Snapdragon 855, 6GB RAMThe 2019-era chipset handles everyday apps and web browsing smoothly, but newer games and heavy multitasking on both screens will show frame drops.
battery
3577 mAh, roughly 5 to 6 hours screen timeWith active use across two screens the battery drains noticeably faster than a single-screen phone; you will need a midday top-up for full-day heavy use.
charging
18W wired, roughly 60 to 90 minutes to fullCharging is slower than current flagships; plan for over an hour to go from empty to 100%.
camera
11MP single lens, f/2.0, no zoomSharp wide shots in daylight with HDR and gyro stabilization for video, but no telephoto or ultrawide means you cannot close in on distant subjects or capture a wide group photo.
durability
Gorilla Glass 5, no water ratingThe glass is scratch-resistant but neither screen nor hinge is IP-rated; spills and dust ingress are real risks for a two-part device.
