Introduction
LineageOS 16.0 is a free, community built, aftermarket firmware distribution of Android 9.0 (Pie), which is designed to increase performance and reliability over stock Android for your device. The port for the Exynos7580 based devices was created by @Stricted and I along with many contributions from other people in the Android community.
All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.
What worksCalls, SMS, Mobile Data
Camera
NFC
WiFi
Bluetooth
Torch
Sensors
GPS
SELinux Enforcing
HWC​What doesn't work
IMS services (VoLTE, VoWiFi, etc). Samsung has their own proprietary implementation. It is not really possible to easily port that to LineageOS.​ Installation
Install the latest TWRP (Available Here)
Make a full backup (just in case something goes wrong)
Do a full wipe (Cache, Dalvik Cache, Data, System)
Download the latest LOS build and transfer it to your phone
Install LOS
If you are installing GApps do it at the same time (preferably in the same install queue)
And finally boot, the first boot can take several minutes as it optimises all the apps​ Downloads

Latest unoficial releases are uploaded HERE
OpenGapps HERE

Great work! Looks and feels awesome @ 1st sight. Will use it as daily driver and report any problems.

Everthing is working so far. There might be a problem with charging over PC's USB port as I noticed today. Connected to my USB2 port battery went to 0% while phone staying turned on. There was no problem charging it with your 15.1 builds installed. But I haven't checked background processes at that time. I'll do on next encounter.
Great work! Thanks a lot.

There were some denials related to usb and the power hal that are fixed in the latest release.
Hopefully that solves your issue.

Hi
Thanks for the great release.
Latest release has some unexpected reboots sometime, but other than that - everything's fine
Great work

I have to confirm this. Happened three times now while phone was on standby.
PS: My phone did not fail to charge via PC-USB anymore.
Right now it failed to charge via original charger. Re-plugging solved it.

I haven't seen this.
When it next happens can you make a copy of /proc/last_kmsg and send it to me.
Kind regards,
Danny

Well, this file is empty. Or this requires root, which i don't have because of google pay. Is it possible to get root and then remove it without full wipe and firmware re-install?
UPD
Also - latest reboot happened after receiving a telegram message. Maybe it has something to do with notifications

Yes you need root to get it from the OS, you can try copy it using TWRP that usually works.

Is the screen less brighter or is it just me?

Hi,
Uploading a new release that may fix the random reboots.
The issue has been reported to me separately on Darios discord so it must be related to my recent kernel changes, hopefully these patches solve the issue.
Change list:
kernel: added some possible fixes for the kernel loop that causes the reboot bug
