No. Yes, I get that there is a setting that turns the screen off to save the battery. But when the screen goes black, and while the call is in progress, you hold the phone out trying to put the call on speakerphone or to use the dial pad and the screen continues to remain black. This used to happen witb my other S4 often. Very frustrating when you needed to use the keypad while in a call. I used to have to end the call, reboot thenphone and try again. If this is a feature of the S4, then the phone is hopeless as a phone.
