This product is a live wallpaper application that allows users to easily set multiple photos as their wallpaper. Users have the option to set a specified image for each screen. To set this application as a live wallpaper, users need to access the settings icon located at the bottom of the screen. However, if the device is unable to acquire the screen position, users can switch the image by swiping the device. In this case, the image will not change when switching screens using the home button, and it cannot be fixed for each screen. The shuffle function can be turned on to switch the image through swipe operations. Certain devices are more likely to succeed in gaining screen positions, such as Pixel, Xperia, Xiaomi, and OPPO. On the other hand, some handsets, like Galaxy and HUAWEI, are more likely to fail in gaining screen position.
