Xiaomi Poco X3 NFC
This is my first time using this rom, so far so comfortable but I have a problem with the heads up notification not working. Apart from that everything is fine. I'm using version 4.8 vanilla (09/16).

Thanks for the hard work.

Came back to this ROM after using ArrowOS for a while. ArrowOS is updated way more frequently, but sadly they don't really monitor the thread for feedback or bug fixing.
WaveOS has been and still is the smoothest ROM for Poco X3 NFC in my opinion. Google Pay also works after hiding Magisk Manager and using MagiskHide on the app.

All around amazing ROM.

Question; i just flashed this rom, after long sitting on a previous version of WaveOS.

With your previous version, the default camera used in, ie my banking app, for scanning a QR code, suddenly switched to the macro lens, something I wasn't able to fix, neither could I found out if it was an app or something I installed.
I was hoping that flashing your new image would fix this. Unfortunitaly this is not the case, all the apps that need a camera by default select the macro lens. Anyone no how to fix this? I do have root and some knowledge of linux. There should be a file somewhere that I can edit manually to use another lens right?

Help would be appriciated.
Hello Everyone,
Decided to give it a chance and try this ROM
Everything looks pretty well but i am encountering small annoying issue with 4G icon on status bar.
Anybody experience that?
Im using Hebrew language but its also happands on English language as well.
I tried to force RTL feature but with no avail.
Any suggestion will be appriciated .
Thanks in advanced

Thanks a lot for this amazing rom! I have one small question. If i download the vanilla build and then flash pico gapps will i run into any problems? I dont want all google apps of the Gapps build. Kudos for your hard work! Take love!

Edit: And will the safetynett pass with pico gapps installed in vanilla build?

    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

    This build ships with fully source-built OSS vendor based on LA.UM.9.1.r1-10900-SMxxx0.0 CAF tag and contains few blobs from MIUI V12.5.1.0.RJGMIXM for critical components like camera and audio. QuicksilveR kernel is included by default. Builds are unified to work on both Poco X3 (karna) and Poco X3 NFC (surya).

    Reboot to recovery
    Wipe data, cache and dalvik cache
    Flash required firmware zip
    Flash WaveOS zip package (gapps/vanilla)
    Format data if encrypted
    (optional) To disable auto-encryption, reboot to recovery and flash DFE
    (optional) Flash latest Magisk for root acess

    UPDATE - WaveOS v4.3 is here!

    This build onwards, WaveOS includes the first fully Android 11 based, stable, custom source-built (OSS) vendor, based on the CAF tag LA.UM.9.1.r1-09100-SMxxx0.0 and using blobs from stock MIUI R V12.0.7.0 only where necessary (such as camera, audio, firmware). Say goodbye to bloated and old MIUI prebuilt vendors, say hello to inline OSS vendor built alongside the ROM and updated with every build!

    This build also introduces and includes QuicksilveR, my custom kernel based on CAF's android 11 sources (LA.UM.9.1.r1-09200-SMxxx0.0), optimized for performance and battery backup and with features such as KCAL and wireguard!

    Since this build ships with Android 11 OSS vendor and kernel, Android 11 firmware is mandatory. Do not flash any vendor zip. Android 10 based custom kernels are not supported. Read the instructions carefully.
