It wouldnt be a phone model version problem would it?
Im not sure of the differences between the 900F's and other models. Surely they should all roughly be the same. Maybe we should keep a log and see if a pattern emerges.
I have been running ART for 4-5 days and had no issues.
Still running stock rom on my 900F aswell (no root and Knox still intact)

Same here: SM-G900F, no root and Know warranty at 0x0 (checked it today)
I've got the same problem for the black screen thing on art. But now I had no such problem because I'm switch back to dalvik

I really think that ART is still unstable! Dalvik is working just fine, I think that the differences between ART and Dalvik are not perceivable for now
