    LineageOS is a free, community built, aftermarket firmware distribution of Android 8.0 (Oreo), 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.

    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 dmesg . (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
    • If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log
    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.

    Stable Builds Archive
    Screenshots attached below
    First BETA build is up! :p

    Feels good to make our way up-to beta. That being said, changelog and FAQ posts are updated. Make sure you read them before asking anything.

    Camera details
    Camera was real struggle to get working on OP2. Maybe I'm noob with cameras lol. Anyways, camera is in working state including video recording. This said, my wonderful testers went ahead and tested several third party camera apps and found out that they all were working fine. This includes Google Camera (from 4.1 to 4.4), OxygenOS Camera (OP2, OP3 and OP5), Open Camera, WhatsApp (Video calling and video recording), Telegram, Skype, Instagram, Snapchat and others. This update also fixes green photos while clicking multiple pictures.
    4K recording is currently disabled on the build to avoid lags and crashes. This will be added when los merges necessary patches

    About HAL3 and Camera modes
    As mentioned in my previous post, HAL3 is implemented and working properly on OP2 Oreo. Enabling HAL3 allows some cool stuff to mess with camera. All the camera modes (HDR, bestshot, RAW and lens blur) are found to be working.

    Things to follow up
    As we're on beta now, my aim is fix rest of minor bugs which are not fatal but sure annoy a lot for some. This will take time and the size of changelog will decrease too. We're insanely lucky to have Oreo running this good on our devices compared to others which are still struggling to get things working flawlessly.

    New journey to stable builds begins now!
    #NeverSettle :cool:

    Though I was pissed to the extreme to see the mess in thread, I also noticed good ones who deserved the piece of work that I did ;)

    I'm sorry to over react yesterday but somewhere it tells me that it was necessary to put few things out. That being said, here's the update. I've worked hard for this update and this brings lot of fixes and squashes out annoying bugs.

    As usual, check post #2 and #3 for changelog and FAQ respectively.

    This for the entitled userbase

    Thank you for the support
    Enjoy Oreo
