dalvik.vm.dex2oat-filter=everything

Very good Lollipop ROM.
There's also a Sergeyl CM12.1 "Standard" version, which is a bit lighter. It's essentially the same ROM with a few less features at settings.

Only photo camera.
It has also green video recording bug. It will probably never be fixed on LP.

Yeah, someone said that samsung galaxy ace 2 camera drivers are just too old, and outdated, so nothing much they can do about fixing camera issue.

Does green camera recording affects only CM app or does it affects all recordings on CM12.1?
Is there a 3rd party camera application that actually work for Ace2 and CM12.1?
Beside camera issue, this is a excellent ROM.

It doesn't work anyway.
You can use Viva video, Camu or Powercam to record video, but with very low quality (480p and 10pps I think).

Thats probably because you dont have access to supersu. It doesnt work without root. So you need to either flash SuperSu zip again or Reflash rom again with factory data reset. I tried changing settings on chrono kernel setting, and it didnt work either, just flashed super su again and it works now easily.

Hey, do you have changed system partitions? Like, making system folder having more space, and having sd card/internal storage space less?

---

Yes, I have memories re-partition since installed KitKat and I keep it when flash LP or MM.

No, I have no problems for now.
There are some CWM zips but they didn't work on my phone, I don't know why. You can find them here on XDA with Google.
So I did it manually, connecting phone to PC and writing commands. The point is if you do something wrong, you'll be in trouble.
I f you want, I can give you the guide I followed, but if you're not sure, you'd better don't do this and try with repartitions zips.

okay, can you link me to working guide? or any of zips, thanks. But need to be working on lollipop. I found threads made for kitkat and older so idk if i can try with lollipop. Also does this repartition gets undo after flashing another rom? or "partioning" is permanent?
