About Corvus OS Android 13

Yes, they are aware that A13 - AOSP has been released.

While it does sound tempting to jump onto the latest flashy android version. It might be too early to jump onto the rat race right now. While it wouldn't take long to do an initial bring-up, but as in user's perspective the situation of A13 may not be in your favour for now. Some of such reasons why they would like to hold on and take it slow is,

1. Obviously as we've seen in the past, initial releases turn out to be buggy or not make much sense in "stability"
2. It seems like AOSP has fixed the backdoor through which certain file managers were able to access android/data or /obb directories. Which means you get absolutely no access to them.
3. All sorts of spoofs, magisk, modules and what not that existed in A12 may/may-not work in A13 atleast just yet.


Corvus A12 is not going EOL, while we strive to make this as stable as it could get please don't come around asking "Android 13 wen?"
