Keypad won't stay open

Question

Keypad won't stay open

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.
