How is this rom compared to aosip?

 

[WewillChen-]

Nice job and thx. :svetius:

So far so good, but It looks like the Auto Brightness doesn't work well.

 

[kleinholzinferno]

Love this rom. Slim, fast, stable and excellent battery life!

Everything works as it should. Auto brightness could be a little more refined and proximity sensor would be nice too. If only we could get updated sources...

Only downside is I have to choose between this and AOSiP.

And OTA updates would be a killer feature for the future.

Great ROMs are coming for this great device.

Camera

Hey, awesome rom. Thank you!

Everything seems to be working perfectly, even got google pay up and running!

The only problem is that the Camera app keeps crashing when i try to open it. Anyone knows a fix for this?

I had that too the first time I installed the rom. Right after opening the app crashed. There were lots of process.media.android errors.

Did a clean install and after the installation I factory resetted. No problems since. Everything is fine. I'm using the latest BSG mod camera for the MI8.

Maybe this helps. I don't even know if the steps I took make any sense or if this affects the problem but it solved it for me.

@palaych: I have compared battery life between this rom and your AOSiP rom and there's a significant difference between the two.

I don't know if the stats are true but could you have a look into it?

First screenshot is Arrow OS, the second one is from AOSiP

I used the kernel that came with the rom, no customisations. All Google apps from the opengapps Pico package, no Magisk or other root.

What are the differences in general ( features ) between the two ROMs ( ArrowsOS and AOSiP )?

Best regards.

Did a clean installation and look what happened:

Best regards.

I think they're pretty much the same regarding the possibility of customisation. Unlike some other ROMs that are adjustable to the last animation these two ROMs focus on (what I believe) are the most important features.

They're customizable but not bloated with settings. Which I think is nice.

All the features I use are there and working well.

Bluetooth hands free is finally working with Android pie
As my main camera I use the BSG Mod camera. Just Google it. Night mode works, portrait works too.
All other apps I use are Google standard and they're working flawlessly. Even Android Auto is useable.

So depending on your needs I'd say give them. both a try and decide. In my opinion you can't go wrong with any of them as they are both fast, stable, slim and have many nice setting to adapt the look and feel to your needs.

Hope this helps
Best regards

Thanks for your explanation.
I´m using AOSiP since last weekend and it´s like you described it. :good:
So, I´m curious on ArrowOS and I will give it a try.
The only thing I don´t understand is that @palaych is spending a lot of
time on developing two ( really good, but ) similar-looking ROMs.

Best regards.

Danke, dir auch!

As I said there are some differences but they are not as huge as between some other roms. The settings are a little different, the icons for some quick settings look different but all in all it's pretty equal.

What matter to me most is reliability and stability and both roms deliver!

I like the slim roms better. I had resurrection remix installed which is also a great rom btw but as I didn't use 75% of the settings it's pretty useless for me. Others may play around with animation styles and stuff but I don't so this is my favourite by now.
