[Galaxy Tab S Android Development] ROM_gamer987:
LineageOS 20 UNOFFICIAL for 2014 Samsung Galaxy Tab S 10.5 LTE/Wifi​

Model: SM-T805 (LTE) - chagalllte - 10.5" screen, Exynos 5420 SoC, LTE

Model: SM-T800 (Wifi) - chagallwifi - 10.5" screen, Exynos 5420 SoC, Wifi

These are the ONLY models that the ROM will work on.

You MUST READ posts 1-4 (about 10 minute read) before deciding to install this rom. If you think this is an unreasonable request, then stop reading now and find another rom. Thank you.

DISCLAIMER

I am not responsible for lost data, identity theft, lost money, security vulnerabilities, bricked devices or any other hardware or software malfunctions that comes as a result of flashing this rom.

All involved in bringing this build to you are working voluntarily on it in very limited spare time, and their other life commitments have much higher priority. Don't expect a prompt, or even any, response to questions and bug reports.

Before attempting to install this ROM

1. Ask yourself: would bricking your device be a disaster for you? If yes, don't try this ROM! It can't be guaranteed stable and reliable enough to depend on for daily use.

2. BACKUP YOUR DATA AND EXISTING ROM. Be prepared for a complete restore if anything goes wrong.

3. RESEARCH adb, fastboot, Odin/heimdall, and TWRP and how to use them, if not already familiar with these.

What works

1. bluetooth

2. wifi

3. brightness

4. external audio

5. audio through headphone jack

6. audio over bluetooth

7. selinux enforcing

8. DRM level 3 (SD definition)

9. deep sleep

10. camera

What doesn't work

1. Fingerprint is completely removed in 19.1 (According to @retiredtab it was not compatible with keystore2)

2. DRM level 1 (no HD definition).

3. Workaround to disable scoped storage. In 18.1 there was a workaround to disable scoped storage, but that no longer works in 19.1. So if you have a lot of apps or data on an external microsd, the performance may be severely degraded.

4. GPS (Works For Chagallwifi)

5. RIL (LTE/4G)

6. Aggressive Low Memory Killer ( Might Cause Apps to crash in some cases, @bluess57 Explained Here)
