The Translation app (com.miui.miscreen in the system) is a built-in MIUI tool designed to wirelessly transfer a smartphone screen to external devices: TVs, monitors, projectors or even other smartphones. It works on three main protocols:

• 📺 Miracast is the standard for screen duplication without the Internet (direct Wi-Fi Direct connection, LG, Sony, Xiaomi Mi TV).
• 🌐 Google Cast – a technology from Google to stream content to Chromecast-enabled devices (e.g. Google) TV or Nvidia Shield).
• 📡 DLNA — Protocol for transferring media files (photos, videos, music) to compatible devices on the local network.

It is important to understand that Translation is not a standalone application in the usual sense, but a system service integrated into the MIUI shell. Therefore, it cannot be removed without root rights or special tools like ADB. However, it can be disabled if you do not use the screen duplication function.

• 🎬 Watch movies and TV shows from the phone to Mi TV or another TV.
• 📊 Presentations and demonstration of slides on a projector without wires.
• 📱 Transfer of photo/video to another smartphone or PC over a local network.
