Chromecasts have made streaming media to your TV super easy.

This workaround helps fix that.

Apps likeLocalcastcan stream media that you have on your phone to your Chromecast.

The problem is, when internet access is available, it can still use mobile data for the connection.

you might disable mobile data on the phone thats acting as the mobile hotspot to prevent extra data usage.

Sharing photos and especially video content to the TV can blow through a lot of data very quickly.
