How do you keep the keypad visible during a call?
When I call a number that presents me with a phone tree, like my voicemail service, I have to enter a bunch of numbers at several different prompts. The screen doesn't keep the keypad open though. It goes black after just a couple seconds. If I touch the screen again, it comes back, but what I touched gets registered as a click, as if I were entering something. But that messes up the phone tree navigation.
Is there a way to keep the phone pad visible during the whole call?
