LineageOS is a free, community built, aftermarket firmware distribution of Android 10, which is designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

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.

Working
Everything, but
Known issues
  • Selinux permissive
  • VoLTE/VoWifi not working
  • Camera only shows up to 8MP
  • NFC is enabled on all models, even on the ones without it (please report device model)
  • Dualsim is enabled on all models, even on the ones without it (please report device model)
  • Screen flickering when using fingerprint (That's normal and how optical fingerprint sensors work. Flickering doesn't happen on stock I know, but that's due to poor UI implement from lineage site)
  • TWRP can't decrypt your data

Reporting Bugs
  • DO NOT Report bugs if you're running a custom kernel or you installed Xposed
  • Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)
  • If it is a random reboot, grab /proc/last_kmsg. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues. Any bug not reported in the bug report format below may be ignored.

FAQ
  • Can I use this ROM to boot other GSIs?
    You can but I won't provide any support. If you are stuck in a bootloop or something does not work, you have to look for a fix yourself. Here is a list of things that will probably be broken when using a GSI:
    • Fingerprint
  • Fingerprint doesn't work anymore after flashing a new build/installing magisk/etc.!
    Redo your fingerprints.
  • I can't enroll any fingerprints!
    Turn off night mode/lower night mode intensity.

II'm so glad to have you, I get to experience Android 10 soon.i will test this rom
I have some question
1. TWRP can't decrypt your data: can i backup the rom? (system, recovery,boot, data,etc...)
2.Camera preview is broken for 4:3 aspect ratio: Does it affect image quality?
3.Selinux permissive: what is this? Is that important?
Wait for your stable version

How would one upgrade from the previous version to this current one while keeping Magisk and root? Just dirty flash it over TWRP without wiping anything? Thanks in advance. ( :

The latest version installs on top of the initial release well but won't run. Do I have to wipe for it to run?

The initial version had problems with making calls from the second sim. Upon placing a call the signal disappeared and connection dropped. in a couple of seconds the connection reestablished.

    here is the proper way to install twrp ,los 17, gapps and magisk. ill provide links at end of post to make it easier. Many thanks to the dev @Grarak. Without his work, we would be without.. Note: you still can not backup\restore data but internal storage is decrypted. Also, Its the second formatting of data after setup that's getting decryption going *If you want faster access to enable wifi, pull your sim before this procedure. **You don't have to use wifi although I recommend it. You do need some kind of access to the internet. If you don't, knox will not let you flash and you could soft brick your device.

    1. get the latest Android 9 Baseband/bootloader for your model using samfirm and flash using odin. setup device using wifi and enable dev options. make sure oem unlocking is on and grayed out saying the bootloader is already unlocked. shut down the device.
    2. Hold both vol+ and vol- and plug into pc. hit vol+ on the next screen to enter download mode. flash twrp 3.3.1-6. when pass, hold vol- and power till device screen goes blank then immediately hold vol+ and vol- to boot back into download mode.
    3. when your back in download mode, flash vbmeta. when pass, hold vol- and power till screen blank then immediately hold vol+ to boot to twrp.
    4. click on settings and uncheck prompt to install twrp. go back. click on mount and make sure mount system partition read-only is unchecked
    5. copy Los 17 20200213, open-gapps nano 20200127 (optional), and magisk 20.3 to external sd card.
    6. Back in twrp, click wipe, advanced wipe and check ALL except micro sd card and usb otg. Slide right to confirm. DO NOT REBOOT. click back and click install.
    7. click select storage and select micro sd card. click on los 17 then click add more zips. then click gapps nano (optional). swipe right to confirm.
    8. once complete, go back and click wipe then click format data. type yes and enter. now reboot to system and wait.
    9. setup wifi and skip the rest. enable dev options and select advanced restart. hold power and select restart then restart to recovery.
    10. in twrp click wipe and format data, type yes and enter. then reboot back to recovery. internal storage should now be decrypted.
    11. reboot to system and setup your device normaly. reboot back to recovery and flash magisk 20.3 and reboot to system. you should now have magisk in your app drawer, update it.

    New release

    https://github.com/Grarak/android_device_samsung_a70q/releases/tag/20191203

    I understand that. some are saying to install 20191025 build first then dirty flash over and will work but I cant get the 20191025 to download fully. Its okay as im not in a hurry. I played around with it so much I ended up wiping out the download mode. I wiped everything and rebooted, twrp wouldn't boot so i installed just vendor from stock and that did not work. took me to a screen that said there was an error updating your device and must use smart switch emergency repair. smart switch couldn't do anything with it so i thought i was screwed but i said lets see what happens if i just flash stock even though i was not on a bootloader screen and it worked. apparently it was a bootloader screen, just not one that looked like one. back on 16 from backup. 16 has a few bugs but nothing major and is very stable.

    I am wondering however if the dev is still working on 16 and 17 or just 17 now? @Grarak

    I have limited time, so I will only update lineage 17 for now
