A user on Reddit has recreated the iPhone Duo's distinctive animation on the Samsung Galaxy Z Fold 8, though it remains a demo and not a system-wide feature. The animation, which transitions between the inner and outer displays as the phone folds or unfolds, was originally introduced with Apple's new foldable iPhone Duo. On the Samsung device, the effect uses the phone's hinge sensor to trigger a visual transition, making part of the screen semi-transparent and revealing the other side. However, unlike Apple's version, this is not yet a built-in feature across all apps on the Samsung device. The iPhone Duo has received largely positive feedback since its announcement, with praise for its software innovations, especially the smooth transition animation. The effect involves the wallpaper dissolving as the phone opens or closes, creating a seamless visual shift between the two screens. Inspired by this, an Android user explored the capabilities of the Samsung Galaxy Z Fold 8 and discovered that its hinge sensor could be used to simulate a similar effect. This led to the creation of a custom animation that mimics the iPhone Duo experience. While the animation is visually appealing and has been praised as "great" and "so cool" by Reddit users, it is not without its limitations. The user who created the demo noted that the effect becomes less enjoyable over time and is only convincing when viewed directly from the front. Any change in viewing angle can break the illusion, a potential issue that may also affect Apple's version once it is released. Currently, the iPhone Duo is the only folding phone with this specific animation. Pre-orders for the device begin on October 16, with starting prices of $1,999 in the U.S., £1,999 in the UK, and AU$3,499 in Australia. For now, Samsung users who want this feature will have to rely on third-party hacks until Samsung implements it system-wide.
