Unlike the original Fold which had an entirely plastic screen, the screen is protected by 30 μm (0.0012 in)-thick "ultra-thin glass" with a plastic layer like the Z Flip, manufactured by Samsung with materials from Schott AG; conventional Gorilla Glass is used for the back panels with an aluminum frame. The hinge mechanism is also borrowed from the Z Flip, using nylon fibers designed to keep dust out. The power button is embedded in the frame and doubles as the fingerprint sensor, with the volume rocker located above. The device will come in two colors, Mystic Bronze and Mystic Black, as well as a Limited Edition Thom Browne model. In select regions, users will be able to customize the hinge color when ordering the phone from Samsung's website.
Hardware
The Galaxy Z Fold 2 contains two screens: its front cover uses a 6.23-inch display in the center with minimal bezels, significantly larger than its predecessor's 4.6-inch display, and the device can fold open to expose a 7.6-inch display, with a circular cutout in the top center right replacing the notch along with a thinner border. Both displays support HDR10+; the internal display now features a 120 Hz refresh rate like the S20 series and Note 20 Ultra.
The device has a single configuration of 12 GB of RAM, and 256 GB of non-expandable storage. The Z Fold 2 is powered by the Qualcomm Snapdragon 865+, which is used in all regions (unlike other Samsung phones that have been split between Snapdragon and Samsung's in-house Exynos chips depending on the market). It uses two batteries split between the two halves, totaling a slightly larger 4500 mAh capacity; fast charging is supported over USB-C at up to 25 W or wirelessly via Qi at up to 11 W. The Galaxy Z Fold 2 contains 5 cameras, including three rear-facing camera lenses (12-megapixel, 12-megapixel telephoto, and 12-megapixel ultra wide-angle), as well as a 10-megapixel front-facing camera on the cover, and a second 10-megapixel front-facing camera on the inside screen, omitting the secondary RGB depth sensor.
Software
The Galaxy Z Fold 2 will ship with Android 10 and Samsung's One UI software; by means of Multi Window mode, up to three supported apps can be placed on-screen at once. Apps open on the smaller screen can expand into their larger, tablet-oriented layouts when the user unfolds the device. New to the Z Fold 2 is split-screen functionality, called "Flex mode", which is supported with certain apps like YouTube and Google Duo.
