Unlike newer Samsung tablets, the SM-T210 does not have an active, unified development hub like Android 13/14 LineageOS. Development stalled around 2017-2019. The most functional ROMs are based on Android 4.4.4 (KitKat) or Android 5.1.1 (Lollipop) . Anything claiming Android 6.0+ is experimental, slow, or broken.
Yes – with caveats.
