A:Answer Hello! Technically yes, with the correct cable, you can connect a USB Type C (Smartphone) to HDMI (TV) and watch from your phone. Keep in mind, that you will technically be mirroring your phone, so you may be limited on video quality, limited battery life, and every notification on your phone will also be displayed on the TV. A Roku device eliminates the need to use a phone, while presenting a more convenient and cost effective way to watch TV. Unlike using cables and a phone, each Roku comes with an easy to use remote that gives you access to powerful features like our Roku Unbiased Search, which makes navigating our catalog of over 500,000 titles easy and effortless. This is one of many reasons why Roku has been the #1 TV Streaming platform in the US for several years running and presents a more favorable Streaming experience.
