Installation instructions:
1. Make sure you have TWRP installed on your device to be able to flash the rom.
2. Download the latest build from the link above and copy it to a place where you can find it later.
3. Optionally download GApps for using the Play Store and other Google related services from here: https://opengapps.org. Choose ARM as architecture and 8.1 as the OS version. The size of the GApps package is upon to you how much apps you want to have preinstalled. Copy this zip aswell to a place where you can find it easy later. If you download it with Chrome or with the Google Drive App it should be by default in the Download folder.
4. Turn your phone off and press Volume UP + Home Button + Power button at the same time until the splash screen appears. Then your device should boot into the recovery. There you wipe following partitions: Data, System, Cache, Dalvik if this is your first install. All of your installed applications get lost by this. Your photos, videos etc. won't get deleted if you haven't ticked the box for internal storage. As the kernel also supports F2FS i would change the filesystem for the cache partition from ext4 to f2fs for a better system performance. Now go to the main TWRP menu, click on install and go to the place where you have placed your zips and first select the rom and then click on the left button if you have downloaded the optional GApps package to add another zip to the queue. Now swipe the slider at the bottom to install and reboot the phone to the system. The first boot can take a while and after booting you could experience some lags because of the GApps initialization but they should disappear after some time.
4. Now you have successfully installed the rom and you're ready to use dotOS on your device. Congratulations!
Bugs:
- VoLTE (isn't working on samsung devices and won't work anytime in the future too)
- Same as LineageOS 15.1

I've created a new Exynos 7580 Discord because the old one from the Lineage 15.1 project got deleted. I regularly share testing builds here. Join if you want . If you have any questions or problems with the ROM, write them also there.

God job, thanks.

Okay as i got some issues reported i need to switch the power hal to stock again :/

---

I found bug with google camera app, when trying to record a video app crashes.

---

Yes i'm currently working on a fix

Alright then!
One more thing: There is a problem with low bitrate audio when recording video on 3rd party apps.

---

Thanks for developer, this rom is lite, I hope that the ROM will develop even better.

---

Wow, i was really waiting for this port. Battery life is much better than any of AOSP projects. GJ and big thank you for porting and fixing it.

---

Found issue of low mic in telegram, whatsupp and etc. danwood76 spent a lot of time trying to solve it and he DID it.
Don't know maybe this information will be helpful for you and maybe he will tell u how easily to fix it.

Did he solved low bitrate audio problem already?

@Borduni is using a fork of my lineageos device tree so my modification to the mixer levels should already be included in his ROM.
Maybe there is a recording volume setting within DotOS that is causing the issue or maybe it uses a different mixer path?

Yep, that was my mistake, mic level is ok

Yes mic volume is ok, but in apps (eg. Snapchat) there is problem with low bitrate audio, same on danwood's ROM.

---

Can't confirm. Made some tests and it should be snapchat that is making the audio worse. For me everything is fine with other apps.

---

If you are facing any performance/battery issues or ui glitches like the status bar isnt working or the list of the latest opened apps isnt displaying i'll suggest you to wipe data, system, cache and dalvik before installing the newest build. The UI should be pretty fluid if you did it like that .

It's strange because on my phone problem occurs on snapchat and other 3rd party apps. Camera app audio working great.
