I have ADB installed on my PC.

USB debugging is enabled on the phone.

ADB devices shows the device and shows it as authorized.

When I enter adb backup filefoldername I get a black screen on the phone that asks me to authorize the backup.

However NONE OF THE BUTTONS to authorize or reject display so obviously I can't authorize the backup.

Clearly there is something wrong but I am at a loss to find out what it is.

Help?
