I'm not sure if this is kernel related bug but I'll give it a try.

When I use Google apps like Chrome or Google, the phone turns the screen brightness somewhere around <10 %. No matter if the surround is dark or light.

If I change between some other app lets say Whatsapp, the brightness goes back to normal. And if I change from Whatsapp back to Chrome or Google the brightness goes back to low.

Every time I use Chrome or Google I have to change brightness higher manually. Anyone else having this kind of issue?


I'm super satisfy with the kernel. Battery is very good and performance smooth as butter. Thank you Dev!

Don't see this behavior on 11.0.5.5 EU and latest kernel build. No issues with brightness at all. I'm not using DC dimming btw.

Hi y'all. I decided to go back from custom roms to stock OOS and flash this kernel because I had bad battery life with stock kernel but at the same time I am not impressed by custom rom camera's for making photos of people.

I have Havoc/LineageOS recovery but don't know what to flash.
Any tips? Thanks
Sounds like you just want to flash the stock rom and this kernel ..

Kernel doesn't care about that really.
You may have some differences because of dynamic resolution, frame rate management and other related stuff.

blu_spark_r101 release

New build is up (y)

This kernel is tested for the 8 Pro and 8T variants which I have, regular OP8 in OOS 11 is said to be working fine by some users.
You can use FKM download kernel feature, just import the links bellow in the app.
FKM download configs: oos


Changelog:
  • Revert "fs: exfat: sync with v5.8-1arter97"
  • defconfig: disable IKHEADERS
  • Remove some logspam and debug
  • net/wireguard: merge v1.0.20210424
  • AnyKernel3 updates sync
  • For root, Magisk v22.1 or newer is mandatory


Keep in mind: I will give no active support for custom ROMs (including OOS based ones).
I am mostly interested on debugging stuff in stock stable OOS (with logs and reproducible steps to replicate the issue).

Will this work on most devices? Or is it designed for a specific device?

I'm asking since, I'm looking for a custom kernel for my Remi Note 9,

Also, won't this remove Magisk root?

-Thanks.

    Hi @eng.stk, what do you think about BBR tcp congestion ?
    Since it's already in the kernel is it possible to let users enable it via config apps ? I think that adding CONFIG_TCP_CONG_BBR=y to defconfig should be enough
    Thanks !
    It's more server oriented, but I can enable it for you to test it out 👍

    This kernel is so smooth and fast, even without overclocking. Can't wait for the next update.

    This kernel sleeps better than a baby on the 8 Pro.

    Thanks!

    DOWNLOAD KERNEL ZIP
    FKM download configs: oos | custom
    (No mirrors please)​


    Setup and troubleshoot: To install just flash the zip on a stock setup with either TWRP or autoflash kernel app.
    If you come from other kernel or have any issues, you should restore your stock boot.img or dirty flash your ROM before flashing blu_spark zip to avoid problems. Also uninstall or clean data of any kernel control app you're using.
    If you are upgrading between blu_spark versions, just flash the kernel zip.

    About bugs and reports: don't bother to post if a log isn't ready or without steps so the behavior can be replicated. I only active support stock OOS ROM with NO mods whatsoever (apart from root). That includes NO support if using xposed, Magisk with added modules, etc.
    If you're using custom ROMs (including stock based ones) and OOS Open Betas you're much on your own. I'm mostly interested on debugging stuff in stock and stable OOS.
    Also try not to spam the thread with OT. There's threads for all kind of stuff, use them.

    Going back to stock: This kernel installer doesn't change your filesystem. You can backup your boot.img with TWRP or kernel app before flashing blu_spark if you want to go back to full stock or just dirty flash your full ROM.
