You might ask, "It’s just a two-second video loop. Does it really matter?"

Because crDroid is built on AOSP, it strips away the heavy manufacturer skins (like One UI, MIUI, or ColorOS). In doing so, it removes the manufacturer’s branded boot animation (the Samsung swirl or the Xiaomi "Mi" logo) and replaces it with its own identity. This is the crDroid boot animation—the ROM’s handshake with the user.

Backup your existing animation by renaming it to bootanimation.zip.bak .
