Android application package named Hyper, 7.15 MB. The name does not say what the app does or which device it is for, so it cannot be tied to a model or repair task from the name alone. APK files install on Android devices once installation from unknown sources is allowed. Since apps outside official stores can carry unwanted code, scan it and try it on a test device before using it on a customer phone or tablet.
