I'm using ArrowOS 11 and want to upgrade to ArrowOS 12.1. What do I have to do? Is there a short instruction?

Thanks. Does it work with TWRP-3.5.2-sweet-Nebrassy.img? What did you wipe? Davlik, System and Cache? Do the apps, settings and magisk remain or are they deleted?
You need the newest 3.6.1 TWRP. Wipe Dalvik, Data, internal and system. After that ever Thing is deletet. I am Note Sure about magisk, but I Thing its also deleted.

Hey all :)

- How do I change refresh rate down to 60Hz?

It's very important to me to save battery life.
Plus the whole system is just snappier at 60Hz as well.

I'm sure many other people would be interested too.

Edit: Figured it out. Use SetEdit, and change peak and minimum refresh rate to 60.0, save. Done.

I'm still getting massive battery draining overnight (around 20-30% some days) on lastest ArrowOS 12 and Vantom Kernel. Anyone else facing this? Any fix?

Check any navigation apps etc running in background. I also installed Universal GMS Doze (Magisk module) and it seems helping. You can check: Settings → Information about phone → Running time (if Deep Sleep has some %). Before that my PixelOS was showing Deep Sleep 0%

    Thanks for sharing this. Did you flash a specific firmware? Currently im on MIUI Global, v., Stable.
    I flashed direct from the MIUI already on the phone, no changing firmware before...just installed orangefox and then flashed ArrowOS doing what I mentioned above.

    I didn't install the last update for latest MIUI version when prompted because I knew I was switching the OS, from what I remember I was on global SKFEUXM at the time but wouldn't swear to that (could've been

    The whole ROM thing is still new to me, with the exception of needing to do an extra reboot to recovery I think I followed the instructions on the vid earlier in this thread.
    And of course some background reading on the orangefox guides to make sure I wasn't going to brick the phone because of a device specific quirk.
    Edit: Thank you Saul, i followed the same exacts steps and everything went fine. Gonna try Arrow for some time in order to compare it to MIUI
    Installed the latest 20221109 build, coming from MIUI Global Everything seems to be good for the last few days, the phone deep sleeps as it should, barely any overnight drain, ram management is amazing, everything is very snappy, no major issues so far.

    A bug I've found is the audio quality or the volume overall, it is quite inconsistent, in whatsapp for eample the voice notes sound very slim and I have to turn up the volume a lot, but then I go back to youtube for example and the videos sound pretty high so I have to turn the volume back down. Dunno if I have some bad setting or if this is normal.
    Are you able to use the split screen feature? I enable all the related developer options but nothing works
    I'm able to use it on mine, I use gestures instead of the 3 bottom icons so I have to swipe up from the bottom to get all of my active apps but holding the icon like the vid shows does give me a working split screen option.
    It's a vertical split as shown, no floating window MIUI stuff as far as I know.

    Understood. Mine doesn't work for some reason.
    I just had a play around with my settings, split screen is still available without touching the extra split screen options in Developer options...they seem to just be there for trying to enable certain apps that don't like split screen mode.

    My main launcher is Nova Launcher but I tested on the default Quickstep which worked as well...perhaps an ArrowOS version issue?
    I'm running ArrowOS v12.1 | VANILLA sweet - October 25, 2022 with November 9, 2022 ready for download.

    The telegram chat group seems pretty active, you might find help on there.

    Feel free to make your own rom with those features.

    It's not polite to demand features in something that is being given away for free.
    OSS or MIUI vendor? People on RN 10 pro using different vendor so it would be helpfull if vendor mention.
    OSS, as all my builds.
