Hi, I have a Samsung Galaxy J3 phone. I have been trying to cast from the phone to my tv. There is a Google Chromecast plugged into the HDMI socket on the tv, and I have the Chromecast and Allcast apps on my phone. I have no problem casting a video. I have an app called Mobdro installed on the phone. When I stream tv channels or tv shows with Mobdro from the phone to tv, it is ok, but live sports channels are presenting a problem. I can watch a particular sports channel on the phone, but when I try to cast, it shows on the tv that it is searching for that channel, but all it shows is the Mobdro logo on the tv screen.
