Why control your phone over a TV?
Modern Xiaomi TVs (Mi TV, Redmi Smart TV, P1) and Samsung smartphones support many features for mutual integration. Controlling your phone over a large TV screen makes it easier to view photos, videos, work with messengers or even games without having to pick up the device, especially for owners of flagship models Galaxy S23 Ultra or Z Fold 5, where multimedia capabilities require a large screen.
In this article, we will discuss all the current ways of connecting, from standard Miracast and DLNA protocols to Samsung SmartThings and Xiaomi Mi Share branded solutions. Also consider alternative applications like AirDroid or TeamViewer QuickSupport, which expand the control capabilities. Importantly, not all methods work equally stable β the choice depends on the TV model, the version of Android TV (or Google TV on the new Xiaomi TV) and the firmware of the smartphone.
