Q1 - sometimes when I am making or on a call the screen will go black and I can't get it back showing the caller or the controls. I haven't yet been able to disconnect a call from the screen - it's always the other caller hanging up that seems to release the phone so I get a screen again. Help!
Q2 - When I don't need to conserve power, I'd really like to have a slideshow of my images going on the lock screen and/or wallpaper. Is this possible and if so, how, please?
