I have a Galaxy Note 4 which has recently started displaying the notification, "Unfortunately, Software update has stopped" randomly. I can click OK and there does not seem to be any harm done, but it's annoying. After an internet search, I discovered that this is a fairly common problem after Marshmallow. I can't follow the directions given on the internet to fix it, which involves clearing the update cache, so I'm at a loss as to what to do.
