Welcome to DF greggpath. If you have a brand new Maxx, it is possible that is still on the GB and hasn't updated to ICS yet...which would explain why the screen shot feature is not working.Originally Posted by greggpath
To check, go to settings and about phone. If your Android version is still 2.3.x then you are on GB. ICS would be Android version 4.0.4. If not ICS, then on that same screen click system updates and your phone should start the update process to ICS.
