I'm a little confused yet again.

One minute encryption is optional and unnecessary, the next minute it is a vital part of any ROM.

I just cannot keep up with the daily changes, it really helps all if the methods stay consistent.-mod edit

I just cannot keep up with the daily arbitrary dogma flip-flops.

Let's see how long this post lasts before the bully brigade and censors once again stifle debate.

You don't understand why encryption is necessary? You can look on Google to learn more.

It was previously broken in ginkgo 11 roms. Now it's fixed. Pretty simple.

I have a severe issue after updating to the new encryption enabled rom.
Everything was smooth and perfect until yesterday morning: the phone didn't boot, stuck at ArrowOs animation. In recovery (OrangeFox) I noticed that /data/app folder was somehow encrypted, showing a list of ransom character. I had to wipe all and start form scratch. I also moved to TWRP 3.5.
Everything went ok until this morning, when serveral apps started to FC: I rebooted the phone and the same **** happened: stuck at ArrowOs boot Animation and ransom character in /data/app.
This time I decided to flash DFE along with today's ROM build, let's see how it goes.

Anyone else facing this issue?
DFE is required after every flash of you want to stay unencrypted.

Google Pay doesn't work on latest nightly (06/01/2021). Need revert to 04/01/2021.

For those who don't work decryption in recovery - you need latest recovery (I switched to OrangeFox) and set up pattern instead of PIN.

I'm currently on the last A10 build and it's works great. Good job.

I've just a question, can you confirm or not if the last A11 build have micam now ?

Because A3 have A11 now (but owners have a lot of problem with this update...).

Thanks for your work and your help.

really appreciate to all devs for making this awesome rom. so far, this is smoothest android 11 rom ive ever tried. i think its good if the devs add feature "auto discharge lvl" because it can help the battery wear.

    I updated every time an update was up , and no problems what so ever , except with data , but i guess it's more firmware related

    I have the similar experience with VANILLA build. Both clean and dirty flashes. No problems whatsoever. But I use microG, not GAPPS on my ginkgo.

    ArrowOS 11.0

    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.
