I've try to update my device but the setting option is not available for me. I try even putting the phone in developer option and nothing I NEED...
you need to provide more information, as to what tv brand or device?
I don't have a Chromecast
I've been using this app since first day but now I can't connect it to my T V . stays connecting and nothing happens
if you do this, by the moment you want to go to the official update will have to wipe the phone first or if you want to disenroll from the beta...
