For those that have the camera die after a certain time of usage or dying and not releasing causing further instances to crash as well running this from a terminal shell will kill mediaserver and cameraserver which will be respawned allowing use of the camera again without a reboot.

killall -9 mediaserver cameraserver

Anyone else get overpowered/distorted sound using this rom after flashing risekernel?
If you flash something with TWRP (no matter if a kernel or some kind of ROM) and reboot to system, then it occasionally happens, that the sound is too loud (only a bit or even extremly).

Then shutdown to power off, wait 5 seconds and power on. To my experience afterwads everything is OK. Rebooting does not help!

It's an older bug on this device.
After flashing I usually reboot with a finger pressed firmly on the loudspeaker to protect my ears. Then I shut down and power up again.

Today's build contains a rather large update.

The kernel has been rebased on top of the latest A720S drop. You can cofirm this by checking the kernel version in settings - it's 3.18.91 now, up from 3.18.14 we had earlier with oreo kernel. This means more security, but also stability since it's newer. Also, along the kernel, the wifi driver has been rebased and all the configs are from A720S now. This should hopefully finally solve the random reboot issue we were facing. Also the new kernel needs this new usb typec hal that we are also now using.

Another unrelated change is that I merged in more options for Ambient Display. Always on is now not the only option available. Lastly, the rom still won't show whether the device is fast charging or not, but it is now possible to disable fast charging via settings (if you have any concerns about heat or battery lifespan).

Need to thank my friend @SGTPresticle for doing all the testing untill everything was finally working.

Is lineage 18 in development?Im dont asking for ETA only a little question

It is not. Long story short the latest hardware composer blob we have is from pie (a720s). This worked perfectly fine in android 10 as well. But in android 11 it already started getting old and is not compatible anymore, meaning that we would need to leave it disabled. This, combined with not that big difference android 11 makes for the user experience, made me decide to skip this android version as the costs outweigh the benefits.

There is still some work left to do in lineage 17.1. So I will keep maintaining it instead. As my free time allows it, of course.

Today's build contains another large update.

Following the kernel, all the blobs and hals have been updated from the latest firmware available to us - A720S pie. We are no longer using any blobs from previous android versions. This could fix some smaller issues we had with those hals before. The blobs in question are: camera, amplifier, sensors, NFC, bluetooth and OMX.

If you ever did any mods to them they will need to get redone. Tagging @Draekko here cause I know you did some camera mods.

    Youtube is still stuttering but no idea why this is the case.

    Could you just flash this zip and report back?
    You can set time frames when live display activates and you can choose hue and how much percentage to remove the blue light filter.
    Thanks, I meddled with LiveDisplay for a while and got it to work the way I wanted.

    Okay I tried viper4arise via magisk and V4A worked but it couldn't fixed my problem.

    I also flashed the pixel experience Rom and there I have the same problem with the crackling in WiFi call. Only on the Rise_Q Rom it works perfectly so well I have to keep to that Rom or buy a different phone but the most phones are toooooo big for me.

    Edit: So I did found a solution at first I guess, I flashed crdroid Android 11 and the RiseKernel-v1.6. I changed in the Kernel adiutor TCP Congestion to "cubic" and it helps a bit on that Rom with the custom kernel. I will try it on lineage again without flashing the Kernel but change the TCP if it helps. ;)

    Edit again: This helped in my case but you have to root your device download the kernel adiutor and set the TCP Congestion to "cubic" or try any other if it doesnt help, at all it isnt solved at all still little cracks but not too much at the moment.
    Will do, I will flash it this evening and report back.

    Is there a way to unflash this zip incase it causes a boot loop?
    It won't. But you just flash any lineage build.
    Could you just flash this zip and report back?
    OK flashed it and upon early testing the stutter is still there. I will play around with enabling force vp9 codec and see if that helps.

    I've noticed it happens even more frequently if I were watching a video, pause the video, then switch to a game while the video is in the back ground paused, then switched back to youtube from said game (but closing the game so it isn't open in the back ground).

    Again thank you so much for taking the time and spending the effort to help me out with this YouTube stutter. And thanks for continually pushing to perfect lineage os on this phone. I personally, and many others as well, greatly appreciate your work.

    LineageOS 18.1 Official for Galaxy A5|7 2017


    LineageOS is a free, community built, aftermarket firmware distribution of Android 11 (r), which is designed to increase performance and reliability over stock Android for your device.

    * Your warranty is now void.
    * I am not responsible for bricked devices, dead SD cards,
    * thermonuclear war, or you getting fired because the alarm app failed. Please
    * do some research if you have any concerns about features included in this ROM
    * before flashing it! YOU are choosing to make these modifications, and if
    * you point the finger at me for messing up your device, I will laugh at you.

    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 Gerrit Code Review.​

    ROM OS Version: Android 11
    ROM Kernel: Linux 3.18.140
    ROM Firmware Required: Samsung oreo firmware

    Help my sim doesn't work
    Please read the installation instructions more carefully. Oreo firmware bootloader and modem is a must.
    You can find the collection along with the guide in THIS xda thread.

    I'm sometimes having crackling sound when listening to music
    Turn off 'ok google now' functionality in google app settings. If you have troubles finding it you can as well go to settings>apps, find app called 'google' and disable microphone permission.

    Does this rom support VoLTE?
    No. And it likely won't in the near future. Samsung's exynos VoLTE implementation is proprietary and non-standard. It is not possible on AOSP based roms for the time being.

    My camera flash doesn't work
    This is an issue with the camera app. Just tap to focus anywhere and it will start working.

    My device fails to encrypt
    1. You were likely using older TWRP, update to the latest version
    2. Backup your data somewhere (external sd, pc...)
    3. In TWRP Advanced -> Format data.

    My hardware keys light up whenever I touch the screen
    Navigate to Settings->System->Buttons->Backlight and tick 'Illuminate buttons only when pressed'. You might want to reduce time on the scaler to 1 second, too.

    How to switch to full screen gestures
    1. Navigate to Settings->System->Buttons->Backlight and tick 'Enable on-screen nav bar'.
    2. Navigate to Settings->System->Gestures->System navigation and tick 'Gesture navigation'.
    New build up!

    This one is huge. The changelog list is big and I've probably fixed more bugs in the previous 7 days than I did in the past 6 months.
    Lineage 17.1 for this device is getting better and a lot of bugs are squashed now. We can now declare this a beta!

    All the changes for this build are now properly sorted and merged-in. You can easily find everything at github.com/LineageOS, build the rom yourselves and contribute with new code, if you are able to.

    • Beta 3.0
      • Pulled RIL blobs from G965F Q firmware (more modern, fixes signal strength)
      • Fixed issues with connecting to RILD (fixes in-call volume, fixes echo in calls)
      • Updated GPS blobs from A720S P firmware (better signal, we are actually able to acquire a lock)
      • Updated fingerprint blobs from A720S P firmware (works more reliably, dropped all hacks)
      • Pulled sensors from A720F O firmware (cleaner)
      • Updated DRM to support Widevine L1
      • More HALs are binderized
      • Build FlipFlap (a flip cover app)
      • Fully written and enforced selinux policy
      • Latest LineageOS sources

    Also I've just updated my sources so you can fully build the rom again.

    I've tested some roms like PixelExperience today on my device. It's not bad with the added 'google' feel to it. Later I might test RR and others.
    All that I'm asking from both developers and users is please be clear that these roms are based on LineageOS. Meaning that most of the hard work that actually got them to work was done here, on LineageOS. And unfortunately most of the issues they are facing as well :p Work was done by RaymanFX, forkbomb, and in the latest days by me. Not respecting this makes me less motivated to keep working on the device.

    Cheers :highfive:
