This is a SELinux enforcing build, signed with public keys, so you will have notifications from "Trust"

Includes 2022-12-05 lineage security updates see -> https://review.lineageos.org/c/LineageOS/android_build/+/345541

3rd version - replace the LineageOs 18.1 camera application with that of Aperture from LineageOS 20.

This allows for video recording.

If you downloaded yesterday, sorry, you need to download again and apply to obtain Jan 2023 security patches.

First Impressions is that 18.1 is an improvement over 17.1 in regards to speed/responsiveness of the interface.

Note: Please DON'T update to LineageOS Recovery - it's horrible , and is not going to work.

This is the ONLY model that the ROM will work on.

Before deciding to install this ROM, please backup anything/everything important.

Also have a build handy you can revert to in the event this build is not working.

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, I am 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

wifi

brightness

audio through loudspeaker

audio through headphone jack

DRM level 3 (SD definition)

deep sleep

RIL - mobile data and telephony/SMS - some limitations for telephony audio options

hardware buttons and lighting

gapps nano version for arm, android 11

What doesn't work:-

Original Camera Video Recording application - as it's the LineageOS camera app, it doesn't save.

This is now replaced by Aperture camera application from LineageOS 20 which will save video.

It's not the fastest but works - hey it's an old device.

DRM level 1 (no HD definition). It is practically impossible to achieve level 1 for HD definition.

If you need HD definition for your streaming media, stay with stock Samsung ROM.

WPA2+WPA3 wifi security on a wifi access point results in no wifi connection.

Logcat displays - "WPA: Failed to select authenticated key management type"

It's in external/wpa_supplicant_8/wpa_supplicant/wpa_supplicant.c at line 1586

Possibly other features that I haven't tested or do not use.
