What Dongle

[kooduquestchin]

I've just done a factory reset on my S4 mini and it looked ok for a while, but then all of a sudden I got this notification:

"Dongle firmware updated. The firmware for the AllShare Cast dongle has been updated. Tap here to enable Screen Mirroring".

I do not have any "dongle", so what is this all about ?. I am concerned that it may be a virus or some other malware.

By the way, I never got this message before doing the factory reset.

The Allshare Cast dongle is just Samsung's version of a Chromecast.....it's just telling you that your phone's software has been updated, whether you have the device or not.
