Today's update fixed screen...

Turning back on during phone calls after having pressed the power button to turn off the screen (during speakerphone mode). The update to 7.0 caused the problem which wasn't present in all previous versions of the OS software

Does this also keep the screen off when in speakerphone mode? I don't get enough calls to be able to test it out until I get to work and can call myself

What carrier are you with, as that may make a difference

yes. Verizon.
