Ships with EMUI 9.0 (Android 9); install the EMUI 10 (Android 10) update first. Launched in China; VCE-L22 is the international model. No built-in gesture or key opens a chosen app: knuckle gestures (where present) only take screenshots or record the screen, and double-pressing Volume down only takes a photo or opens the camera. In China, VCE-AL00 and VCE-TL00 later moved to HarmonyOS (Android-compatible); last_os follows the global EMUI release, which ends on Android 10.
