Xiaomi Mi TV 4 (including Mi TV 4A, 4C, 4S and 4X) supports several ways to sync with smartphones, from wireless screen broadcasting to control through the branded Mi Home app. However, users often face problems: the TV is not visible on the network, the application does not connect, and mirroring works with delays. In this article, we will analyze all the current ways of connecting, including hidden settings and bypassing typical errors.
It is important to understand that the methods differ depending on the phone model (Android/iOS) and the firmware version of the TV. For example, for Mi TV 4 on Android TV 9, Google Cast is available, and for older versions, we tested all methods on devices in 2018-2023 and collected working solutions even for non-standard situations โ for example, when the TV and phone are connected to different routers.
If you just want to duplicate your smartphone screen on a big screen, Miracast or Wi-Fi Direct is enough, and if you want to control your TV as a smart device (turn on/off voice, adjust channels), you will need the Mi Home app and Xiaomi account binding. Below are the detailed instructions for each scenario.

5. Connect via Mi Share (for file transfer)
If you need to transfer files (photos, videos, music) from your phone to your TV, use Mi Share (formerly Xiaomi Share), the equivalent of AirDrop for the Xiaomi ecosystem, which works without the Internet and allows you to send files at up to 10 MB/s.
