BubblePaper Live Wallpaper is a free personalization app developed by KramerTech for Android devices. The app allows users to draw bursts of colored bubbles by touching the screen, which then float about and bounce off the sides before disappearing. The wallpaper's background, bubble color, blur, and bubble size are all customizable, giving users a personalized experience.

The app is surprisingly addictive and provides a visually appealing wallpaper for any Android device. However, it is only compatible with Android 7.x (Nougat) and above. To enable the live wallpaper, users need to long-press on the background of their home screen.

It is important to note that the app does not support live wallpaper on certain obsolete phones, including HTC Aria, HTC Legend, HTC Hero, HTC Droid Eris, T-Mobile G2 Touch, myTouch 3G Slide, HTC Wildfire, and Samsung Intercept. If the app does not work on other devices, users are encouraged to contact the developer for assistance.
