i have a hp chromecast and i can't connect my samsung s4 nor s5...the laptop doesn't recognize neither of the devices and bluetooth doesn't work either. what can i do?
Welcome to Android Central! Are you saying you have a Google Chromecast? HP doesn't make Chromecasts. In order for it to work, the Chromecast needs to be plugged into a TV with an HDMI input, the Chromecast has to be plugged in separately to a power supply using the AC adapter, and everything needs to be on the same wi-fi network.
