no "official" ban yet... but don't take it out during flight. you
don't want to be noticed by one of those flight attendants
on a power trip.
my friend got hassled by a grandma United flight attendant
on a SFO-HNL for having the "Note 7" phone turned on.
His phone was a new iPhone 7 Plus (not a Samsung product,
last time I checked) Against his better judgement, his argued
back. The flight attendant said he would have to keep the
phone turned off during the entire flight just because she said
so... or else she was going to inform the captain and made
sure my friend was arrested for interference with flight crew
or something.
He has the whole incident on his phone and
I'll post the link once he uploads it to YouTube.
