First post here - I have a strange WiFi Issue after using WiFi direct on my s4 with a galaxy tab3.
Whenever the wifi is switched on,on the tab 3 my s4 won't connect to the wifi network.
If I turn the wifi on the tab3 to off,my s4 instantly connects to the wifi again.
This only happened after using wifi direct to send files between the 2?
I can see no ongoing connection between them so am puzzled - Any ideas??
