Face time not opening

application crashes or won't start or you it doesn't want to activate??

if it crashes or won't start try to check your latest update version first if the problem still happening try to offload the application data from (settings>general>iPad storage>scroll down tell you see face time >offload App

if this also didn't work try delete it and download again

if problem still exist I advise you download latest os system for your device on your computer and use iTunes and setup the os again to have fresh clean start
