I have noticed an excessive amount of lag while scrolling on an excel file (using Google Sheets) using the latest 2 builds. Disabling HW overlays in developers menu helped a lot.

Same behaviour happens while scrolling on Instagram home page (i mean daily use scroll, not something fast).

I'll try to record a logcat when i get home.

But anyway thanks a lot for your work.

Persisting in this latest release, long press home button area will wake the phone - despite being switched off in settings. (S8 G950F)
I looked into this with the aid of my friend Google and it appears to be something (a bug?) that Samsung introduced with Android 8 or 9 updates a long time ago on the S8.
Please can someone confirm that this original Samsung bug has not been fixed and I am wasting my time looking for a solution ?

It's not a bug, it's the 3D touch function that came first with S8.

Anyway, good news, you can disable it. You'll need to be rooted and you'll need a root file explorer.

1. Open file (eg. with Root Browser): System/usr/keylayout/gpio_keys.kl
2. Look for: key 172 WAKEUP
3. Delete "WAKEUP"
3. Save file and change file permissions to: -rw-r--r-- (644)
4. Reboot

By revert, do you mean that the HWC HAL is disabled for now? If that's the case, that's too bad, but I'm glad you were able to get yourself a working device. Again, thanks so much for your work, it really means a lot.

Screen grab doesn't seem to notice this behavior 🤔 I tried recording from a different device although the camera can't seem to view it like my eyes do 😄 first part is with HWC on and next I disable it. You can tell UI is smoother with HWC disabled.
I see what you mean now, especially in light of the new build.. it's just having been using Samsung's stock ROM for years now, Ivan's build even with the slight lag still felt smooth 🤣

I was trying to do a video screen capture earlier, but it causes so much overhead that there is no noticeable difference on video.

What I could do was set HWUI rendering to display on screen and compare results with HW overlays enabled and then disabled. That, at least, I could screen capture, as attached.

Also, how did you accomplish to dowscale DPI?

Edit: I just noticed my screenshots show that Battery Saver is on, but the results are the same when it's turned off or charging.
Used easy DPI changer from app store. Actually only changed the resolution, which stopped phone from overheating in WhatsApp calls..

It is getting very hot without hwc in normal use, is there any hope for hwc back in near future builds?

    here it is August security update

    Nothing major in this one as i am still working behind the scenes on that huge update i talked about previously which involves rewrite of almost whole graphics and media stack (its almost finished but i still have to do a bit more testing just to make sure there is no regression)
    (Im still waiting for a properly working s8/n8 listing to show up on ebay thats not overpriced so i can use it for testing as my s8 has messed up display and unfortunately import from UK turned out to be more expensive than s8 would be worth)


    In other news android 13 should be released next month and since there were no major changes s8 and note8 should be running it soon after release with not too many issues and ill try to take a few days off from work to get it up and running on it once source is out



    Once again huge thanks to everyone who supported this project, helped cover build server cost and got me coffee with donations.

    This project wouldnt be alive without them as i do this in my free time as a hobby.

    Thank you very much Ivan
    glad to keep 8 series alive, and well next few updates will be more exciting

    Morning all,
    I am coming from the PixelExperience ROM, because it does not meet some of my basic requirements:
    • SafetyNet passed, by default (without using Magisk)
    • Battery draining too fast
    • Heating issue in some occasion

    I would like your feedback / comment, on any of these points, please?
    Cheers
    Good day,

    It is a stable and good rom and I use LineageOS as my daily driver , for your questions:

    1 Safetynet is NOT passed by default, you still need Magisk. I am not aware of any Android 11 or 12 rom for the S8 that does this have this function out of the box without Magisk (with Magisk it is working great by the way).
    2 My battery is good and I do not have any issues, there are still some major improvements expected like HWC support. But I have better battery life on Lineage than on Stock.
    3 Haven't had any heat issues.

    For me LinaeageOS 19.1 for S8 is the perfect rom, but I do not know if this is the case for you, as mentioned by requirement 1. I hope this helps making a decision for you.

    And Thanks Ivan for your continued development for our (old) phones.

    Anyone else having issues with not finding certain apps in play store / getting error with not compatible? Like revolut
    Also, am I missing some settings, as the camera is capped to 1080p and many options missing, like format, codec(hevc) jpeg quality etc
    No, I have Revolut installed and working. It showed up just fine in the Play Store for me. No apps have complained about anything actually. I installed it via TWRP along with the GApps package from the OP. Other than missing a few options from the stock ROM (like screen resolution and flashlight brightness), I've had zero problems. The phone is also way snappier than it was with the stock ROM. Firefox in particular ran like a two-legged dog before I switched. It's still not quite as buttery smooth as it is on my Poco F3, but it's not far off now. As for the camera, I chose to install IDan's GCam build. Works like a charm.

    Thanks to Ivan for the hard work.

    Thank you very much for this rom Ivan. The battery life on my S8 G950F is astonishing really. I was previously using an /e/ rom with ~3 days of battery life if left idle. With this rom my battery only drains 10-15% per day if my phone isn't used much, giving me around 6 days before really needing to charge my phone. This is great for someone like me who doesn't use it much. Cheers!

    Keep in mind that some LineageOS features have not been completed yet this is not a device bug and please do not report those

    d) dmesg




    Install gapps right after installing the rom itself don't try to boot to system before that if you want to use gapps (Or wipe data before installing them)

    Since most gapps didnt update for 12L yet (SDK bumped from 31 to 32) i edited falmegapps and uploaded them here use them if you cant find gapps that work on 12L https://mega.nz/folder/FFoS1IIK#XunGRNTViQY7-OZ8oQr0sg
    Make sure gapps you decide to use support android 12L/12.1/Are targetting api level 32

    Make sure you are using latest official TWRP before installing rom older versions do not have proper android 12 support

    As prommised here it is Android 12, Big thanks to everyone who supported project with donations that helped cover the build server cost and get me coffee
    If you want to turn off auto live display (Yellow tint) type "Live" in settings search and go to LiveDisplay
    28
    I havent posted an actual progress update in quite some time so here is some behind the scenes.
    • First of all selinux, that is actually being worked on and it should be supported in near future (Tho it needs some testing to make sure things dont break)
    • Kernel upstream and full eBPF support, thats on its way too so we wont need any hacks to make bpf work anymore which is a nice bonus + we will be able to use some nice new features like gpu monitoring which requires eBPF
    • HWC This is a big one, without revealing too much there is big progress on this behind the scenes and while it does require quite a bit of work once this is sorted we will have much better battery life and UI will be waaay smoother (2x increase at least), this and few other hals will be open sourced too once this is nearly finished so no more proprietary blobs for it
    • Keystore will also be looked into a bit further to see if there are edge cases left where some secure apps break
    • OMX again without going into too much details we will see some changes on that end and it will be open sourced
    • Camera, well ill just let this one be a surprise for now since it will require most work
    There is a lot more going behind the scenes and some of those changes will take some time (Keep in mind i do this in my free time so i really cant talk about etas) but in general once most of those chanegs are up 8895 devices will be in perfect condition and once android 13 source is out it wont take too long to get it working.

    Some other small notes since s8 i use to develop this rom on has broken screen (i use scrcpy to mirror screen on pc) im actually still looking into getting 8895 device, Someone offered to send one from UK but since im in EU ill have to look into import tax and stuff caused by brexit which is not fun to deal with.

    And finally HUGE thanks to everyone who supported this project and helped cover the build server cost, thius project really wouldnt be possible without them, They also covered the coffee cost and some stuff like recent keystore fixes really took a long time to debug which indeed required a lot of coffee at night haha.

    Since my birthday is tomorrow I decided to release a little surprise build. Here is a brief changelog:

    - Synced with LineageOS source

    Im aware of Seedvault issue curently present and im working on a fix for it.
    I wanted to release something as a gift from me to everyone using this rom and supporting this project throughout the years. Keeping older phones alive and up to date is really fun hobby and I don't think I would've kept doing it if it wasnt for all of the support from the comunity.

    Once again big thanks to everyone who helped cover the build serve cost and coffee.

    Enjoy new build and stay safe

    here it is August security update

    Nothing major in this one as i am still working behind the scenes on that huge update i talked about previously which involves rewrite of almost whole graphics and media stack (its almost finished but i still have to do a bit more testing just to make sure there is no regression)
    (Im still waiting for a properly working s8/n8 listing to show up on ebay thats not overpriced so i can use it for testing as my s8 has messed up display and unfortunately import from UK turned out to be more expensive than s8 would be worth)


    In other news android 13 should be released next month and since there were no major changes s8 and note8 should be running it soon after release with not too many issues and ill try to take a few days off from work to get it up and running on it once source is out



    Once again huge thanks to everyone who supported this project, helped cover build server cost and got me coffee with donations.

    This project wouldnt be alive without them as i do this in my free time as a hobby.
