> I switched to iPhone, in part, because Chromecast's casting protocol was so unstable. It just... stopped working consistently.
I had a similar problem with some (Android phone) apps. Casting a movie, and after half an hour or so the app would lose its connection to the Chromecast. Which meant you couldn't control (e.g. seek backward/forward) the movie anymore without restarting it (the movie). This didn't happen with some other apps though, e.g. the Google TV app. Apparently it is easy to not properly implement the Chromecast connection. Perhaps the connection gets terminated when the phone goes to idle mode, unless you do something to prevent that.
Yeah, that was a common issue with me. I had significantly worse issues though, my chromecast would hard lock and/or have very strange visual glitches that required a reboot to fix, typically about 10-20 minutes into playing something. That's if I even got to that point because half the time it would just refuse to actually play anything without a reboot 95% of the time I went to use it.
