New Update! (Clean Flash is needed)
Finally Cepheus it's official!


Look at main post! Link for download is in PixelOS Website. In this build I moved to Retrofit Dynamic Partitions, so that's why TWRP and OFOX won't be supported. There's only 1 issue mentioned on main post too.

Device feels more smooth now. Battery doesn't drains fast too. I hope y'all likes it. If you find colors strange, that's how natural colors should look, if you want you can change to Saturated in Display>Colors

Make sure to follow properly instructions, enjoy!
In the last update, I've used the ROM for about 1 week, but the battery drain was even superior to other AOSP ROMs. No matter what app I froze or uninstalled I never i had a minute of deep sleep (0% deep sleep). I could only get 2 hours of SOT, only work calls and e-mails, by midday I was on 30% battery. I had no choice but to go back to MIUI 12.5. because I really need the phone to go through the day on a single charge.
I'll wait for the users feedback, hoping everything is ok.
Thank you for your work and good luck in your university studies.

There could be many things that lead to 0% deep sleep, in my case it was good like 95% of the time. It's okay, if you want then wait for feedback ^^
Also, thanks! Yes will put a lot of effort on university : )

Hello on the PE for cepheus, the locking and unlocking is very beautifully done. the screen starts to glow from the lock button. and it also turns off, first the left part turns off and gradually the entire screen, the last pixels fade out near the button. can you do the same please? ☺️
and this is a very nice ROM, thank you so much 👍 good luck to you 😉

I have a question. the Wi-Fi hotspot is not working.
the access point turns on by itself, the computer sees it, I can connect to it. but the internet doesn't work.
the usb modem is working fine, the internet is spreading
 
Hello,
I installed the ROM yesterday and now realized that my Mi 9 is not fast charging, does the ROM supports fast charging?
Do I need to change any setting?

Xiaomi Mi 9
With last oficial update, there is a fm radio app which is useless as we cannot connect wired headphones (and there's no radio chip at all in cepheus). And I've not been able to uninstall through adb. Could it be removed in next update, please?

The rom for me works well, and coming from PE+ I just miss a couple of switches (clock to the right and different battery icons). It's quick, it doesn't warm too much, battery is ok. The only thing I have not tested yet is NFC.

Great job.

NFC works well, too. I'm actually using it.

Another thing that is a bit annoying for me is that when changing to another app for a while, the previous is hard to keep. Normally it is closed and must be restarted. Guess it's for saving battery, but when gaming it's not the best option. Anyone with the same experience?

I'm having a very annoying bug.

When charging, the phone thinks that I have a wired headphone connected and goes berzerk.
Now, I can't play anything with audio, the phone freezes and crashes. Reboot does not work. Connecting a headphone or speaker (wired or bluetooth) also does nothing.

Anyone knows what to do?

Well, something similar. Playing CoD with bluetooth headphones, when connectimg the cable to charge, sound disappears. I have to switch off/on bluetooth and sound back to normal through bluetooth.

Hope it helps.

    Hello everyone!
    Sorry that I haven't updated XDA. I fixed link of super_empty.img, which was deleted before. Thanks to Rakib Hasan for pointing it out.

    Also, I've been working on PixelOS A13, don't ask for ETA, but all I can say is that device side is ready (Thanks to Evasi0nXiao for trees). I'm just waiting for source and release.
    Clean flash for a13 will be mandatory so prepare your backups xD.

    Edit: about the <no sound while charger is plugged> issue, will be gone for A13 so don't worry.

    Here you can read more about PixelOS A13!
    > Teaser 👀

    Hope y'all have a nice day!

    PixelOS for Xiaomi Mi 9 (cepheus)

    PixelOS is an AOSP based ROM, with Google apps included and all Pixel goodies (launcher, wallpapers, themed icons, google sans fonts, Monet color based system wide theming, boot animation), a fork of OG Pixel Experience with improvements on the top of it. Huge respect to Pixel Experience team for their work, thanks to them for making this ROM possible.
    In short a fully functional Pixel Experience with just the right amount of essentials.

    * thermonuclear war, or you getting fired because the alarm app failed. Please
    * do some research if you have any concerns about features included in this ROM
    * before flashing it! YOU are choosing to make these modifications, and if
    * you point the finger at me for messing up your device, I will laugh at you.
