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.

Before attempting to install this ROM

1. BACKUP YOUR DATA. Be prepared for a complete restore if anything goes wrong. If you use TWRP as listed in the FAQ, you should also backup your EFS. You have to flash TWRP before moving to LineageOS. The Option is under "Backup" in TWRP.

2. RESEARCH adb, fastboot, Odin/heimdall, and TWRP and how to use them, if not already familiar with these. For flashing this release you only need ODIN and TWRP.

3. Some hints are listed in the FAQ below

4. If your overarching goal is giving your good old tablet a second life, please give this ROM a try :)

What works

camera

Slightly increased main volume and removed AudioFX package

What doesn't work / issues /hints:

For telephony audio, only the loudspeaker or using a headset option is working. If you receive a call on stock-rom, the loudspeaker is the only preset that you can choose from. There is no kind of built-in mic. The problem that both calling parties can hear each other only after a couple of seconds is fixed. The device from 2015 does not have the best mic or a second or third mic for echo cancellation. That's why I strongly recommend using a headset.

the team will not spend anymore time looking at fingerprint. If you need fingerprint to work, stay with stock Samsung ROM.

DRM level 1. There's more detail in post 1891 above. You can achieve version 1.2 depending on installing google-packages.

If you charge the device while it's powered off and then want to power it on, you MUST wait at least 30 seconds AFTER disconnecting the charger cable before pressing the power button otherwise you might run into strange boot problems such as the touch screen not working. While recent builds solved the touchscreen issue, you still might see excessive battery drain until you perform another reboot.

Perhaps some other that I haven't tested or do not use.
