ArrowOS 11.0

ABOUT
ArrowOS
is an AOSP/CAF based open source project started with the aim of keeping things simple, clean and neat, both for the Android system and users. We understand the pain of unnecessary and sometimes rarely used mods/features being shipped with custom roms nowadays which may end up causing battery drains and/or memory leaks & crashes. This is being strictly avoided on our side keeping everything to a bare minimum, delivering stable performance all the time without destroying the AOSP interface. With users getting more used to tweaks and features, we added just the right features and customisations that will be actually USEFUL at the end of the day.

I set the animations to 0.25x speed and the rom became like a jet. Less specific but wonderfully stable. Battery performance seems to be good too. 😃

After installation I had some trouble first, then most of them were resolved by auto or reboot. Whatever was working "Device Personalization Services" was constantly giving a "stopped" error. I also disabled it and problem solved. 😂

The device does not go into sleep mode when Bluetooth is turned on. I checked it with the BetterBatteryStats app.

Battery performance is not what I expected either. It is more better than MIUI 12 of course, but I would expect better battery performance from such a lightweight rom.

Edit: Battery performance is fine actually.

    Where can I find walkthrough to install microG for this rom? May you help me?
    Download F-Droid and install.

    Then copy this URL to your phone's clipboard.


    Go to F-Droid, then tap on Settings > Repositories > Plus Sign + at the top right corner. Copied URL will automatically assigned to the relevant fields. Of not, add them manually as

    URL - https://microg.org/fdroid/repo
    Fingerprint - 9BD06727E62796C0130EB6DAB39B73157451582CBD138E86C468ACC395D14165

    Tap on Add and make sure it's enabled. (Toggle the button to ON)
    Go to f-droid home and pull down (Like in browser) to refresh the repositories.

    Now, search for these apps on F-Droid and install them one by one.

    1) MicroG Services Core
    2) MicroG Services Framework Proxy
    3) FakeStore

    *If any of these apps are not appear in your search results, probably you did not add the microG repository correctly.

    After installing all these apps, restart your device. (Not essential but I did)

    Now, Find the MicroG Services Core app on your app launcher and open it. Then go to Self Check at the top and make sure all options has tick (done) marks. If not, tap on that option and give permissions and make it done. 🙂

    After checking all options, go back to MicroG Services Core app's home screen. Turn on Google device recognition, Cloud Messaging, Google Safety Net if they are off. Login to your google account if you need. It's optional. (It will not give any output if you logged in successfully.

    That's all. 🤘

    Build - September 24th Vanilla
    No root
    No Encryption
    MicroG Installed without Root
    No custom kernel (ROM's original kernel)

    I have flashed this ROM on last Saturday (It's 6 days now) and so far so good. Followed the exact procedure as the original post says. All files downloaded via the provided links by the developer.

    Smooth and great as daily driver. If someone like to give it a try, try it. Recommended. Thank you devs. ❤️

    You can find an installer that does the job in the magisk repo, it's called "microg installer revived". Or you can use nanodroid for example. Cheers

    Hello.

    Does anyone use the Zepp app for Amazfit watches on this ROM ?

    I noticed one bug.

    If I want to add my own photo to the watch display in the Zeep app, unfortunately it doesn't work :-(

    After selecting the picture nothing happens.

    On other ROMs, however, after selecting the picture, the editor normally pops up in which I crop the picture according to my preferences and then upload it to the watch.

    Can anyone who also uses Amazfit and the Zepp app try this ?

    Thank you very much.
