During a "Power Off" my TF300T (with the most recent firmware update installed) entered "Safe Mode" with an intervening sick Android robot (it had a superimposed exclamation mark!) No permanent adverse consequences that I can detect on subsequent rebooting and the Safe Mode went away.
I have yet to see on this Forum a formal description of the orderly way to enter Safe Mode or a discussion of its purpose. On this site: How to: Enter Safe Mode in Jelly Bean – Droid Life it is claimed to be a new feature of Jelly Bean 4.1, but I was unable to deliberately induce this mode following their directions.
I would appreciate guidance on this issue. Thanks.
