Thank you for your effort, smooth rom with great ui, only thing is I'm having slow charging issue (china variant). Hope you fix it, rather than changing kernel (have no choice) honestly, no custom kernel is at par with your QS. Cheers & Best regards!

If this is discontinued can I ask what ROMs in this device are you still maintaining?? Also ignore the duplicate I don't know what I'm doing just to reply this XD

    Does it support Sunlight mode?
    Does it support Wifi Coverage Extend Option?
    Does it support whitelisting apps from dark mode?
    Does it support MIUI Camera with the same stock 48MP quality?
    Does it support adjusting freeform windows despite the manifests?
    Does it support skipping unlocking the device with a PIN after a reboot
    Does it support invert-nav-bar (force close back button)?
    Does it support Game Mode?
    Does it kill apps in the background for just switching between them?
    Does Mi sound work for wireless and wired headphones?
    Does it support pop-up?
    Does it show internal shared adopted storage on TWRP?

    And does it have ADB over network/NTFS File format/Soft Reboot/Advanced Power Menu/Quick actions via pop-up notifications.

    If it does all of these, I may pay the time and effort to change into your ROM despite that I need to resetup Magisk and Edxposed and System Settings.

    Hard luck with development 😁💚

    This ROM does not support those that can't spend a second looking up what it supports and half of the things you are requesting like "game mode" is just nonsense and the other half is AOSP 11 which ALL 11 roms support.

    One exception applies, it does use SLMK kernel LMK which is a horrid solution but still better than any other kernel LMK solution, I don't know why devs insist on this age old bullshit when LMKD gets weekly updates and works FAR better. It's this inclusion strategy of kernels by devs who don't understand anything about the Linux kernel that makes me wonder if I shouldn't just start over.

    However, you either try it or you don't, no one gives a flying **** which you decide to do so go away and once you are away, stay away.

    WaveOS v4.x - Rasmalai 🌊

    WaveOS is an android custom ROM based on AOSP, focused on delivering a perfect blend of aesthetics, functionality and performance out of the box. The version 4.X is based on Android 11. Various optimizations and enhancements have been merged from CAF and upstream AOSP to maximize performance and battery backup, and improve OS functionality. We provide a unique and beautiful user interface out-of-the-box that's inspired by OnePlus' OxygenOS, and can be tweaked to your liking. We've also added handy features and customizations that improves user experience and proves to be useful at the end of the day, rather than bloating the ROM with unwanted features and customizations that could cause stability issues. We hope you like it! #NeverBetter

    No, LMKD does NOT kill any processes that are needed, that is the entire point of it, it's part of the android system instead of a hacked together kernel module that is supposed to be equal for all devices of every single ROM out there from all versions.

    LMKD uses PSI to determine memory pressure and CANNOT kill needed processes or even relevant ones in the system, the "pinned" stuff is respected by LMKD but not by LMK or SLMK.

    Oh and I forgot, the entire "android personalization services" thingy that they all include anyway is designed to use LMKD, if you don't, it won't work right and things will conflict. Most ROM devs don't get how this work yet either and most don't care either for some reason. that is WHY PE is my choice of supported ROM, becacause while they **** up all the time, at least it's AOSP and I can fix it before release.

    I've been a kernel dev before either of them were even born.
    What rom do you recommend for the redmi note 8?
