Regarding the Backlight Dimmer, when I enable it I can lower screen brightness well below normal levels, but that also is true for the whole range of brightness levels. What I mean is that also when setting to max bightness the display is still less bright than normal values. I don't know how it's supposed to work, so if that is the intended behaviour then everything is fine, just thought I mention it in case it's not :)
Also is there a way to enable/disable the dimmer switch from terminal/tasker, or even control how much lowe the brightness can go?

Can anyone please confirm if Xposed for Oreo works with this kernel? I know Xposed for oreo is still in beta, but just would like to know if the device boots without any issues. Any bugs in Xposed will soon be smoothed out I expect.
Thanks

Loved using this on 8.0. The backlight dimming feature was phenomenal, eagerly waiting for an update for Android 8.1!

Not sure if this is a kernel problem but also not sure where to ask this (if you could point me in the right direction I would be grateful).
When I take a call and then receive a notification the sound of the other person cuts out, also I don't hear any notification sound. I tried disabling notification sounds but the problem persists. I also tried to google for a solution but could not come up with anything even coming close to my problem.
Here is the relevant logcat: https://pastebin.com/rk7dQ7Cu

Hello. I have the bootloader unlocked and I have root, but I use stock room and I do not have twrp installed. I have no experience with fastboot, could you tell me which commands to use?
I use version 8.0 Android stock

It's simples. Thanks.
Do I need an expecific app to make some changes in kernel feactures ?

Well, I installed the kernel. As I already had root (I did root some time ago through a file called boot.img, I did not use any manager like magisk or supersu) I installed the kernel version without the magisk. However, when the device called, I noticed that it had lost root access. Then I tried to install the kernel version with magisk, however the device still has no root. I tried to install the boot.img that I used to do root previously but to no avail. How can I proceed?

flash kernel.

boot into android.

download Magisk, transfer to phone. boot into TWRP, flash magisk zip file.

PS:- flashing a kernel, you will loose root.

    So... I have not had much time lately to work on X4 stuff. But I did find time to build a script to inject the TWRP ramdisk into whatever boot image happens to be on the device.

    It works, but for SOME reason it seems to always boot to recovery. Weird. I need to figure out why this is happening. Once I do, we should be able to use the bootable TWRP to flash a TWRP installer ZIP after flashing a custom kernel.

    This seems like a much better scenario than having to recompile TWRP with each new custom kernel as it is released.

    Will update again in a few days when I nail down this recovery bootloop.

    If anyone wants to look, the ZIP is here (again, DON'T flash it as it bootloops): https://drive.google.com/open?id=1UzCz5sgJGCZJZ9ws_H4XZkxOQioWeyoc

    It is frustrating that I spent 2 months trying to make a boot image start directly to recovery, and now I can't seem make one that DOESN'T. :)

    would it be possible to add support for lowering minimum screen brightness?

    will try in next update.


    Edit:

    Update r3 is here
