Samsung Galaxy S5 that I used to connect to my TV with an HDMI cable broke and I now have a Samsung Galaxy S7. I can't connect to my TV with the HDMI cable. I don't have internet at my house as it isn't available. Any suggestions on this phone or If I update to a newer Samsung will I be able to mirror my phone to my TV without internet? If so, which version should I get? Verizon suggested the Chromecast Ultra but everything I read, says I need internet. Thanks for your help....very frustrated.
