Android application package named YouKnowTV, version 1.5, around 17 MB, apparently a TV or streaming app judging by its name. No target device, chipset or firmware build is stated, so compatibility cannot be determined from the name alone. APK files are installed on Android TV boxes, smart TVs or phones through a file manager, a USB stick or adb install. Check that the device allows installation from unknown sources and that its Android version supports the app before handing the unit back.
