TV Remote turns your Android phone into a remote for your smart TV. It finds TVs on the same Wi-Fi by itself and works with Samsung, LG, Sony BRAVIA, VIZIO, Android TV, Google TV and Chromecast, with no brand to pick. Press "Allow" or enter the code on the TV once and it reconnects after that. It also mirrors your phone screen, sends photos and videos to the TV, and lets you type into TV search with your phone keyboard. Free, no sign-up.
