[Galaxy Tab S2 Android Development] retiredtab:
PLEASE BEFORE YOU decide to try this rom, you MUST read all of post 1, 2, 3 and 4 (about 10 minute read). If you think this is an unreasonable request, then stop reading now and find another rom. Thank you.

This is ONLY for the SM-T713. I do not have and will NOT build T719 and T819. See post #2, FAQ 20. Any questions asking to build these will be ignored.

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.

BACKUP YOUR DATA AND OLD rom BEFORE trying my rom.

If you are NOT an expert in using fastboot, adb, odin, heimdall, twrp, DO NOT use this rom. You must know how to use these tools to revert back to your old rom. If you are new to flashing custom roms, do NOT attempt this. If you need your tablet for work and something important, do NOT flash this rom. This rom could result in a bricked device ,boot loop, complete loss of data or non booting device or you not being able to revert back to your old rom.

Known issues/What doesn't work/what's not tested

NOTE: If any following features are important to you, don't use this rom as I will not be fixing them because I

i. don't use/need that feature

ii. already tried fixing it and couldn't succeed and won't spend anymore time on it.

1. Stock camera doesn't work at all (reason i and ii). Starting with LineageOS 19.1 and higher, camera API functionality (pictures and videos) isn't even recognized by the OS. The Samsung camera drivers are proprietary so they can't be changed and there's no open source implementation.

For more details, see post #57

2. fingerprint (reason i). I never use it and I see it doesn't even load correctly in the logs.

3. ARM64 gapps (reason i). Some of you require gapps for whatever reason. I use Aurora Store for my purposes and thus have NO KNOWLEDGE of the current state of ARM64 gapps.

There are various gapps projects (at least 5 in 2023). Each has pros and cons. It's your job to do the research and find a suitable gapps project. I suggest you allocate at least a couple of hours/days doing your own research. My rom works by itself fine without gapps. DO NOT talk about gapps in this thread.

4. full disk encryption has been deprecated in Android 13 (LineageOS 20).

5. If you restart the device with the purpose to reboot it and the usb cable is plugged in, the device will not reboot and stay in charging mode. Simply unplug the usb cable, wait 15 seconds and restart the device.

6. Live Display (reason i and ii) doesn't work as it crashes every second and causes the OS unable to boot. See

https://github.com/retiredtab/msm8976-common/commit/50c08ec0641a893b1572219ba1d5f46db20c5be0

7. If you want to disable the taskbar and the 3 soft button navigation, you MUST disable the 3 soft button navigation first via settings, system gestures, system navigation, then disable the taskbar via settings, system, buttons. If you do it in reverse order, the device will become very laggy and unresponsive and you have to reboot to get rid of it. Once rebooted, it will work fine.

8. Random reboots. If you're getting random reboots with battery level at 50% or lower, it's highly likely that your original battery does not have enough amps and is worn out/degraded. There's nothing I can do about this. You need to replace your battery.
