My Samsung S4 mini (4.4.2) can not mirror the screen to my Samsung Smart tv. Everything was ok a few days ago, but not now... Tv says "Screen Mirroring: Connecting to xxx", then black screen about 20 sec with message "Loading" at the top right corner => The message "Screen Mirroring: Screen Mirroring has ended" appears in the upper left corner of the TV-set screen.
Is the Android 4.4.2 quilty?!?!!
UPDATE: S4 Mini overheat and battery drain after Update NK1 and several other problems; connections etc.
