How do i keep the phone on during a call

[Android Central Question]

It times out to the bank screen after about 10 seconds. If you need to add numbers you need to press the power button to reopen the screen

Check app like Stay Alive that will keep screen on for any app you wish.

Welcome to Android Central! Which phone? What do you mean by "bank screen"? Do you mean the screen goes blank?

If you're on a call, the phone screen should automatically go blank if you bring it up to your ear -- that's what the proximity sensor is for. Is that not happening on your phone? Or is this during a speakerphone call?
