If the screen of your Android device stops working when you are setting up the ExpressVPN app, it is likely because you are using a screen filter app. A screen filter applied on some Android versions will prevent you from tapping your screen to prevent you from opening unsafe items.
To resolve this issue, disable the screen filter app that is active on your Android device and continue to set up ExpressVPN on your Android.
If the issue persists, contact the ExpressVPN Support Team for immediate assistance.
