So here's the deal: anytime I'm calling a robot voice and it wants me to input a number (like an account number or something) and I pull up the keypad, things get weird. Specifically, if I try to punch in a number then half the time the screen blanks out and doesn't let me put any numbers in. This is a huge nuisance because then I get the robot voice saying "I'm sorry, please try again" a million times.
This doesn't happen if I'm calling someone to begin with - only if I'm already in a call.
What's the deal? Is there some sort of setting I'm missing? Or is my phone just old?
