If you are an apple/ios user, you may want to try pressing down the home screen and the power off button for at least seconds to turn the device, then repeat the process to turn your device on. You should see the apple logo after you turned device on. Wait for a minute or so and you should be back to your home screen.

It is highly ADVISABLE you check your storage for an available gigabyte in order for brave frontier to work.
