Followed the installation instruction, everything has been smooth so far. Played some game and the performance is great. Prop to the maintainer for writing such detail instruction rather than having me search though everything on my own. Keep it up!

And im on MIUI 12.5.1 android 11.

Do i have to downgrade or something in order to flash this ROM because when i flashed other custom ROM it did require me to downgrade to miui 12.0.2 android 10

Thank you in advance.

This custom ROM is probably one of the best in terms of customization, it passes safety net, it's certified, OTA works, it is smooth... I think I've tried one before that was a tiny bit smoother, but I would not give everything else for a bit more fluidity. I think I'm staying with this ROM for good. I recommend you flash latest 12.5.1 FW A11 before flashing this ROM.

Thanks for info. I must find some solution for that volume custom ROM problem since MIUI gives me headache with WiFi problem that has no solution.

Fist of all I don't use GAPPS, only microG installed via Magisk. Everything seems to be working just fine except two things.

1. It looks like something is wrong with sensors. Compass shows wrong directions (I use the Trial Sense app, form F-Droid) and also the position (x-y) of the phone seems to be switched (it can be visualized better in the Bubble lvl in the app) -- it wrongly recognizes horizontal/vertical angle, apparently it thinks the right-left plane of the phone is the top-bottom one. When I hit the compass icon in the phone's nav bar, it hangs the whole phone after 10-20 seconds. There's no way to switch the icon back to the off state, and I have to reboot the phone.

2. The volume buttons on my earphones don't work. The only button that seems to work is the power one. The phone's hardware buttons seem to work without issues. I tried two different earphones (connected via minijack and also the usb-c port), and I got the same result, which is I can't change volume via the buttons. Pressing vol+ or vol- on the earphones seems to be issuing a tap action on the screen, so for instance I can tap on a Firefox icon using either one of the volume buttons.

Does anyone experience such behavior?

It looks like the camera also have issues. Nothing what you would see while using it, but when you start any camera app, for instance the stock one, or OpenCamera, you will get the following spam in logs (this scrolls the output at the speed of light):

The only way to make it stop is to disable all the sensors via the tile in developer options. Also it looks like disabling sensors per app doesn't work at all. I mean the stock one which can be accessed via app info and also the one that crDroid provides in its settings.

The same thing happens when GPS gets a fix.

It looks like, there are some issues with the notification mechanism. Basically all apps, which don't use the google push system, can't receive notifications. It's the case for Telegram FOSS, Signal, and K9-mail. They all have disabled battery optimization and they all have a visible notification displayed in the nav bar/lock screen.. But the network connection breaks after a few minutes you turn the screen off. Often notifications don't work when the screen is on -- you have to access the app to receive them (as soon as you access the app, the notification is delivered). Is there any fix for this issue? Does anyone noticed this behavior?

Good news is that, it looks like the official (the newest) firmware is bugged somehow. The same errors can be observed in the stock MIUI12A11. So it's not the crDroid's fault.

But still the delay in receiving notifications in the case of crDroid is really weird.

    I think so. I''m from Poland, so I flash only EU or global firmware depending which one is the newest.

    There's no A12 firmware for redmi9, but you can use the latest A11 with crdroid 8.5 and it works well.

    You are right, this is similar problem. When I reboot phone in airplane mode, then I get all channels working. If I enable GSM and restart WiFi, then channels 149 - 173 stop working. I can see in logcat, that country is set to PL, but regulatory info looks the same (or I don't know what to look for).

    @tiga05, yes, I've managed to solve it, but I don't really know what consequences of my deeds can be, so be careful if you want to follow what's below.

    Basically, you probably are right about some buggy ROM<->google relationship. To deal with this spam log, you have to disable com.google.android.gms/.chimera.GmsIntentOperationService . You can do it via ADB:

    Code:
    # pm disable com.google.android.gms/.chimera.GmsIntentOperationService

    I'm not sure what this service is used for (it's just a part of google GMS, i.e. google play services), but it looks like everything works well so far.

    I've also been playing with google play services optimization for battery utilization and RAM usage. Basically I disabled these activities/services, which reduced RAM from 450M to around 140M, which is really nice.

    hello, yeah it is present in this custom rom... its a problem with all custom roms for redmi 9... i switched back to miui because of this issue
