[Samsung Galaxy A40 ROMs, Kernels, Recoveries, & Ot] kevios12:
Welcome to CesiumOS, yet another AOSP project. But this is one that will be a very different and exciting project. What differentiates us from the rest, you ask? Well that's why you're here - to find out.

*Note This thread is optimised for both Light and Dark XDA themes. View this thread in a browser to have a magical experience!:D

CesiumOS is a project that is designed to be exciting. It is something that was born out of a sea of similar-looking AOSP roms. We offer a unique, yet familiar experience for your phone. We cherry-pick features that we think will *actually* be useful in your daily lives, and nothing more. Since this is the beginning of something beautiful and exciting, we will continue to add more features in the future releases. We will strive to keep the ROM bloat-free, yet still have enough features that will keep you satisfied.
