How many average Android users would know how to do that?
so they carry on as before using their device blissfully ignorant of the disaster about to happen when they open a vid sent from a friend.
As has been said, this is the problem with Android. Makers stop updating devices as soon as they can get away with it. My old HTC device got ONE update. That was it. All support was pulled 6 months after first sale.
That was one of the reasons I ditched smartphones alltogether and went back to a dumb Nokia.
