First, a critical clarification: The SM-T210R is actually the Samsung Galaxy Tab 3 7.0 (released 2013). The Galaxy Tab A 10.1 (2019) has model numbers like SM-T510/T515 . If you meant the SM-T210R (Tab 3 7.0) :
Official LineageOS: None. The last official builds were for LineageOS 14.1 (Android 7.1), but those are long deprecated and removed. Unofficial work: Yes, there are old community builds (typically Android 7.1 or 9.0) on XDA Developers. However, they are not maintained , have bugs (Wi-Fi, camera, audio, or performance issues), and require an older recovery (TWRP for lt02wifi). Verdict: Not recommended for daily use. Hardware is very weak (1GB RAM, ancient GPU). Use a lightweight stock-based ROM or a debloated KitKat if you must keep the device alive.
If you actually meant the SM-T510/T515 (Tab A 10.1 2019) :
Official LineageOS: Yes for SM-T510 (Wi-Fi). LineageOS 20 (Android 13) and 21 (Android 14) are officially supported. SM-T515 (LTE): Often has unofficial builds but less official support due to RIL (calling/SMS) issues. Workability: Works very well. Smooth performance, updated security patches, and most hardware (audio, Wi-Fi, Bluetooth, sensors) functions correctly. Requires unlocking the bootloader (which trips Knox but is fine for custom ROMs). smt210r lineageos work
Final answer for SM-T210R: There is no current, stable, or officially supported LineageOS for that device. Find an old XDA thread if you want to experiment, but expect poor stability.
