I have looked just in case I missed it. No reverse wireless charging. No OOS camera, don't think any ROM has that. As for Dolby Atmos, not natively but there is a magical module for it from the razer 2 if my memory serves me correctly. Have not flashed it so cannot say whether it works or not

This is a small project based on AOSP. We try to be a platform for beginners and support the Custom ROM community with our own unique contributions as well. This ROM exists thanks to inspiration of AOSiP, Thank you! #StayDerped

I have looked just in case I missed it. No reverse wireless charging. No OOS camera, don't think any ROM has that. As for Dolby Atmos, not natively but there is a magical module for it from the razer 2 if my memory serves me correctly. Have not flashed it so cannot say whether it works or not

Reverse wireless charging is present in the available quick settings tiles, I tested it on OP9pro and can confirm it works fine yet I'm having a bug with the tile which show RWC always off unless I remove it and add the tile again. But again it does work.

Yes you are right I just searched in settings, forgot the term power share. My bad

 

[novo2o]

Hello, I noticed the gestures in OOS settings (gesture when screen off) are ignored after reboot : they stop responding until I set it again. Haptic feedback also seems off even when turned on. Still best ROM Cheers !

Love this ROM so far but Im wondering if theres a raise to wake feature for the ambient display I cant seem to find one

Can I have a link to crowdin? For Russian translation

 

[Onapami]

Try this Platform-tool.

1. Install recovery: fastboot flash boot file name.img
2. Reboot to recovery
3. Choose option factory wipe/data wipe
4. copy-partition zip in adb sideload (if you want but recommended)
5. Reboot to recovery again after copy-partition zip from adb sideload
6. Install rom through adb sideload file name.zip
7. After successfully install rom factory wipe again (recommend)

First make sure drivers are installed properly.

Holy ****, after 4 days are almost not sleep, I've FINALLY managed to install this freaking beauty thanks to your comment !

Thanks a lot (I can finally go back to sleep... )

does this rom have ethernet tethering?

 

[hi2all123]

Hello, could someone please give me some info about this rom? Does this rom support 120hz? Also is the movement/scrolling smooth and push notifications works without any bugs? What about camera? is it in same quality as it is on OOS12?

You could have found this by scrolling through the posts

Yes it does support 120Hz
It's smooth if you use some FKM tweaks which you can find on one of these pages (to lazy to link it, use the search button)
I use a GCam which can also be found on the OnePlus 9 Pro xda forums, its not the same quality unfortunately but it does the job for me. A dev from another ROM mentioned he's working on bringing OOS cam to android 12 roms but it's not ready as we speak

 

[DonnerPlays]

No scrolling issues in my case, didn't change any kernel settings
