Thanks to Evasi0n and lamjiidii for trees

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.

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?

I'm running Urnyx05 for standard fotos and Shamim for astrophotography since it has 'infinite' focus. But device is under crDroid 7, i. e. Android 11.

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

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 ??

No, i've used the arrow os DT by lamjiidii as base. you can check the DT here.

Did you clean flashed the latest update?
Also what Gapps, if any, do you use?

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.

 

[Ww222]

Yes from clean flash, and im using nikgapps

Can you flash PixelExperience kernel and check whether the problem persists or not?

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.

Hello, can someone that don't have root check the status with rootbeer? Thank you

 

[wviana]

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?

 

[toscha42]

If your device is not rooted then this special app rather detects an opened bootloader. In this case there's nothing you can do.
