Android APK with a Chinese title meaning 8K high definition TV, with the note in brackets saying no ads. It is a 13.6 MB software package for Android devices, apparently a television viewing application, though the name gives no version, developer or architecture details. Technicians setting up Android TV boxes may sideload it through a file manager or adb. Since nothing about compatibility is stated, test it on the target device, verify it installs on that Android version and CPU architecture, and treat unsigned third-party packages with caution.
