Hello guys, I'm a newbie here.I've got problem with screen mirroring and need your help. I have SGS3 and LG Smart TV WebOs.AllShare Cast connects to the TV,and TV connects to phone.But then phone writes something like "connection failed.AllShare Cast will be closed".Questions:1.Can I fix it somehow? 2.Are there any ways to mirror androids' screen wirelessly (or not wirelessly, or without any adapters)?
