If you wish to uninstall the app named Snow, and you discover it to be "grayed out", i.e. you are unable to uninstall it, it is by design.
The Snow app requires administrator access to the device, which is why one cannot uninstall the application until somebody removes "Snow" from the list of device administrators.
Step 1: Open the Settings app on your Android device, and scroll all the way down to Security and tap on it.
Step 2: Look for an option named ‘Device administrators’ or ‘All device administrators’, and tap it once.
Step 3: You should now be seeing all the administrators listed with their name, as well as a short description of what those administrators do. Notice the check marks next to the names? These are the administrators that have been enabled. You can disable or enable any administrator on the list here.
Once you have removed Snow from this list, you should be able to uninstall the Snow app.
