The 2021 update for the CVTE MSD338 platform (configured with 512MB RAM) primarily focused on security patches, Android OS stability (typically Android 6.0/7.1), and HDMI-CEC improvements. Unlike updates for 1GB+ variants, the 512MB version prioritized memory optimization over feature addition. No official Android version upgrade (e.g., 7.1 to 9.0) was included due to hardware constraints.
