ABOUT
ArrowOS is an AOSP 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.

FAQs
Q: VoLTE icon is missing! How can I enable it?
A: Settings -> Display -> Statusbar icons -> Enable VoLTE icon
Q: No dark mode in Phone and SMS apps!
A: Either install Google Dialer and Messaging from the Play Store, or enable "Override force-dark" in Developer settings
Q: Where is Dirac audio enhancer and how can I enable it?
A: Go to Settings -> Sound -> scroll to the bottom
Q: 2 Big cluster CPUs are always offline! Not able to turn them on!
A: When CPU load is low, these cores are turned off to save power. They will turn on automatically when CPU load increases. If you still want to turn on cpus disable core control in EX Kernel manager or a similar app.
Q: HELP! everything was fine until today but suddenly my screen stopped responding to touch and I had to reboot!
A: It turns out that k5/plus units with certain display panels have some issues with DT2W (double tap-to-wake) enabled. You can go ahead and disable it in display settings, the issue should disappear after that.

Hi adityhya rom I use the way you say performance has increased really good rom now I wish you more success and new privatization plenty of roms waiting for you to meet us

I used this rom for a short time (I'm still used) It is very stable at the same time and curious item, the front speaker played ringing sound (too useful because my rear speaker is rusty)
Launchair bug does not open after reboot
And the battery consumption is very high, consumes a lot and it takes a long time to charge.
Other than that, great rom.

The battery consumption is a bit high, even in deep sleep
Thanks so much ,Good job ??

Poor call quality reported by person on other end of the line - A6020, Q, Arrow OS
Hi,
First - When I call or someone calls me, the voice of the person on the other end is loud and clear. But the person reports that nothing of what I say is audible. There is too much of noise, or a howling voice is heard from my side. The issue normally occurs when there's HD calling b/w me and any other user (And both have Volte active).
Second - Google voice typing, WhatsApp voice messages and voice recorder does not record anything from the microphone.
Third - Pls add a tweak for mapping hardware buttons in settings.
Fourth (And of very little need from my side)- Pixel Launcher crashes with full gesture navigation activated. Up to 2 button navigation, everything is fine except that from 2 button navigation, the Google app seems to stop working, often executing after a minute from being tapped on the icon and Google assistant doesn't activate.

Encryption worked for me, many thank!

First, thanks for extending the life of this model , second I have noticed that the battery consumption during use is high, I have activated the minimum, no application that works in the background, the only thing that installed extra was the magisk

Hello Everyone !!
I need help I bricked my phone , I was just going back to my stock rom then I am facing two problems ..
( I am not blaming this thread developer , I appreciate him for his work as I also used his ROMs )
Now my problems are :
1)-When I flashed stock rom using Qfil tool ,its showing baseband version unknown and I don't have any backup file for this ... So can I restore my baseband version.(does again flashing stock rom will fix it?)
2)-this is my main issue that my device is boot only when connected to charging. If I disconnect charger it suddenly turn off and won't turn on without charger...
And my battery is at good condition so I don't think its a battery problem.
Thanks for reading !!!
I hope anyone wil help me ...!!!
