This may seem confusing but I need help. When I place a call the screen goes black not allowing me the option to end the call, turn on the speakerphone or use the keypad during the call. The same thing happens after I press the answer button on an incoming call.
But the catch is the phone allows me to use the buttons when I have headphones in the 3.5 mm jack. This is confusing to me and I do not have the TTY mode on or anything.
I need help solving the problem so that I do not have to have headphones in the phone to be able to end the call or use the phone during a call. Please help
