My case also shows those sprinkles and it smells musty, maybe it got a bit humid? They didn't seem to put Silica Gel into the box, I suppose they didn't expect it to be stored in the warehouse that long...
I'll try to clean it and wait some days if it gets better, if not I'll order a fresh case from Lastu since it's pretty nice and they seem to need some support anyway.

About Alien Dalvik: No stability problems (but upgrading to 2.0.1.7 was the first thing I did), I had to manually change the Android language to German though (as explained in https://together.jolla.com/question/...guage-problem/ ). And I don't see an icon for my installed Netflix app, workaround see https://together.jolla.com/question/...-netflix-icon/
