How to Reset Google Chromecast
When you want to stream your favorite movie, TV show, music or other content, you can connect your device to your TV via a USB cable or simply use a Google Chromecast.
There are so many things you can do with your Chromecast, but sometimes even the best device can experience irreparable hiccups. You might run into issues or it might just stop working altogether, leaving you without streaming content.
If you just bought a new wireless router, are planning to sell or give your Chromecast to someone else, or if the device is freezing or slow, resetting it may do the trick.
