- 🔗 Interact with other Xiaomi devices via Mi Home or HyperOS (e.g., transferring a screen from a smartphone to TV).
It's important to understand that UniPlay is not a standalone application, but a system service that works in the background. It doesn't have its own interface, but without it, many of the features of Xiaomi are not. TV Mi Box will be unavailable, for example, if you turn off this service, you may lose access to the system:
- 🎞️ Reproduction of content in 4K HDR on some platforms.

adb shell ps -A | grep -i unipayIf the command returns a line with the process, the service works. If it doesn't, it may have been disabled or deleted.
What if UniPlay Service is not listed in the app list?
Method 3: Verification through system logs

1. Data collection: Like many Xiaomi system services, UniPlay can send anonymous telemetry about content playback (for example, what video formats are used). However, this information does not include the user's personal data. If you are concerned, you can turn off the collection of statistics in the TV privacy settings.
2. Vulnerabilities: Because the service works with DRM, It's a potential target for hackers, but there are no major vulnerabilities associated with UniPlay, and Xiaomi is releasing security updates regularly, so it's important to keep the firmware up to date.

If you want to minimize the risks:
- 🔒 Turn off sending diagnostic data in the TV settings.
- 🛡️ Update your firmware regularly.
- 🚫 Do not install unofficial service modifications.
