ArrowOS 12.0
Redmi Note 8 (ginkgo) / 8T (willow)

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.

    Bastante bien, he notado que consume más rápido cuando la batería está al 100%-80%. Mi teléfono puede sobrevivir un día entero con un uso intenso (brillo máximo, de 3 a 5 horas de pantalla) y aun así llego al final del día con un 21 %.
    Thank you very much for your answer bro.

    Plase guys, I would like to install this rom...but I dont know the differecen beteween have a ROM encrypted ou not encrypted; can you tell me?

    Thank you very much
    To my understanding, a non-encrypted ROM can have its files and everything related accessible in recovery mode even if there is password/ pattern set on phone.
    While an encrypted ROM will always ask your password/ pattern in recovery mode. So no one can access your data even if they have your phone and have installed TWRP or any recovery somehow.

    As far as I know, the ROM is encrypted by default, I'm talking about ArrowOS v11 and I never used Disable dm-verity.

    I attached a photo of how internal storage looks like in TWRP.
    I agree, this looks encrypted.

    Hello, I wanted to know how the battery is doing in this rom, because I have noticed that in miui it spends more than 30% and when the phone is not used at night, thanks in advance
    Pretty good, i've noticed that it consumes faster when battery is 100%-80%. My phone can survive a whole day with intense use (max bright, 3 to 5 hours of screen) and i still get to the end of the day with 21%.
