It will work, for ICS and lolli. most likely kitkat as well, just remember it could be vulnerable to any threats, although those chances if you don't do shady stuff are very minimal in my decade of IT support.It has been a very long time since I even suspected a virus coming from a flash exploit, but still the potential is there.
