you have used LOS18.1 device sources ??? Your link is pointing to main LOS github. And there are no 19.1 device sources for cepheus ??

Well, then maybe your GCam doesn't support it properly. I've no problems with GCams on crDroid. In any case I can't imagine it's related to LOS.

Cheers

Which GCam APK are you using? Could you share the link please?

My GCam started to crash when switching to video mode. 😢

Hi
Have you changed the kernel?
I would get random freezes on Pixel experience kernel but on Pixon, I haven't had any so far.
Also you can check the repo here.
No. Didn't changed kernel. Just flashed your ROM, firmware and Gapps.

Just notice it actually don't restart. It dink wake up the screen. I still able to turn on flashlight by holding power button for example. So it still up, but screen don't light up. Is there a way to get some log and try to figure out what is happening?
 
Hello everyone,
I have a couple of questions ragarding this ROM that I would like to address before flashing (I am planning to switch from Xiaomi.eu):
1. Is call recording available natively?
2. Does this ROM have a toggle to switch on/off the second SIM like in MIUI?

Thanks a lot in advance,
yes and yes

I'm really curious about this bug. I faced this problem on several version of PixelExperience ROM with no solution - I had always to get back to stock ROM. I cannot understand how it is possible that it works fine for someone, but not for somebody else. Does the Cephus have hardware differences or what.

One more question - what firmware have you used? The exact version. My stock rom is EU so when there is firmware from different ROM it could cause the problem - but it's just an idea, in fact I don't know where the problem is.

Just did a clean install last night.
ROM feels smooth and great. So far so good.
A small issue is with digital wellbeing: even if I chose gapps with full support of it, on this ROM time limit doesn't work, while in other ROMs with same gapps it works.
Also, I can't find Monet customization options.
Will it be possible to add face unlock feature?
Thank you for your brilliant work, this ROM will probably be my long-lasting one.

ROM REVIEW (Build: 22/05/2022)

I admit it: firstly I was a bit scared of the "unofficial" status of the builds, and of the not-so-frequent update schedule.
But I was wrong!
ROM is very stable, battery is unbelievable, performance is smooth and you won't desire anything more.
Some basic personalisations are missing (for ex. custom Monet color, Monet-like homescreen icons, length of vibration, Dirac sound enhancer etc) but you won't miss them.
Everything is a total DOPE; the only NOPEs are: Face Unlock is not implemented and Digital Wellbeing does not fully work.
LineageOS goods all work like a charm.
I 100% suggest you this ROM.

Hi there. I have an important app detecting this ROM as root. Just have plain ROM installed, didn't do anything about root. Is there a way to make it work?

    Hey @Ww222
    Thank you very much for porting this awesome ROM to our devices.

    After a week using it, some times my phone shuts down. Do you know where could I get information to investigate what is going on?

    Also, isn't there a repository with your port code? So we may open issues and other devs try to contribute?

    This Mi9 is my main device, I would love to help maintain LineageOS for it.

    Can someone explain to me what sense it makes to install an unofficial and most likely broken ROM? I can understand it with test smartphones, but not with a smartphone you use every day.
