Is there a way to fix the IPhone 4 so my face doesn't hit the buttons while making a call?
That's not normal. The display should sleep when you hold the device to our ear. Try a reset. Press the Sleep/Wake button and Home button for ten seconds until the Apple logo appears. Note: No data will be lost
Do you have a case or screen portector on your phone? One or both may be occluding your proximity sensor.
