When I'm trying to type in numbers to get through an answering service, the keypad won't stay open. The screen actually goes blank while I'm typing. I have to press the button to get it to wake up, and, if I'm lucky, I can get another button pressed before it goes to sleep again.

This is the only problem I have with this phone, but it is becoming very irritating. I just had to enter a prescription number 3 times. Is there something I'm doing wrong to make it go to sleep?

iPhone 4, iOS 4

    This is not a normal function of the iPhone. There is no setting or nothing your doing wrong.

    To be honest these are the solutions that may or may not work.

    First thing I would try is rebooting the phone by holding the sleep/wake button and home button for 15 seconds until you see the white apple logo.

    If that doesn't work I would restore from backup. If that doesn't work I would restore as new. If all else fails take it to your closest apple store they may replace the phone for a working one..

    There is a proximity sensor above the earpiece. It blanks the screen during a call if the phone is close to your face so it will not get key presses if it touched your face. Do you have a case on the phone, or is your hand near the earpiece while you are entering the numbers?

    I was suspecting the case. I have an Otter. Really, with my tendency to destroy things in my pocket, there is no other option. I'm guessing the case is setting off the proximity sensor.

    I wish there were a way to turn the proximity sensor off. For the moment, I may have to resort to taking the case off for those types of calls. That's not an easy task with an Otter.
