I have Xperia SP (4.1.2), and the TV WiFi direct screen says that one device is connected, but when registering from mobile, it says cannot connect with the tv. What should I do?
It's possible that the software or the phone is not compatible with the TV you want to control. For a list of compatible devices, I recommend checking the following link: http://info.tvsideview.sony.net/device.html
Locate the sticker on the back of the TV to check its series. That number needs to be found on the compatibility list. Additionally, remove the software and re-install, then make sure you're connected to the same network.
