Smt210r Lineageos Work [new] (2026)

Since you didn't specify a platform (Reddit, X/Twitter, a forum, or a blog), I have drafted a few variations ranging from a development log to a general announcement.

The Samsung Galaxy Tab A 8.0 (2017) carries the model number SM-T210R. smt210r lineageos work

LineageOS on the Samsung SM-T210R – Current Status & Working Features

Common Issues & "The Work" Required

If you get LineageOS booted on the SM-T210R, the "work" shifts from installation to maintenance. Common issues reported by users of unofficial builds include: Since you didn't specify a platform (Reddit, X/Twitter,

• Deep Sleep/Suspend: A classic tablet issue. The device may fail to enter deep sleep mode, causing the battery to drain rapidly while the screen is off. This requires kernel tweaks or using apps like Magisk modules to force wakelocks.
• SELinux Mode: Unofficial builds often ship with SELinux set to Permissive rather than Enforcing to force compatibility. This lowers security but is often necessary to get the camera or audio working.
• Camera Compatibility: The camera HAL (Hardware Abstraction Layer) is notoriously difficult to get working on custom ROMs for Exynos devices. Users often find the camera crashes or records at low frame rates.

❌ What Does NOT Work (The Dealbreakers)

• Hardware Acceleration (HWC): This is the biggest killer. The Hardware Composer is broken. This means your GPU does not properly compose layers. Swiping home screens stutters, and app transitions are laggy.
• Camera: Both rear and front cameras are non-functional. The app will crash or show a black screen. No fix is available due to missing HALs (Hardware Abstraction Layers).
• Deep Sleep: Sometimes broken. The tablet may drain battery overnight from 100% to 30% because the CPU never enters idle mode.
• Video Playback: YouTube via the official app is a slideshow. You must use an older version of YouTube Vanced or NewPipe with software decoding. 720p60fps videos are unwatchable.
• Rotation Sensor: The accelerometer is unstable. Auto-rotate often freezes, requiring a reboot.
