Whatever problem you're having, it's not normal. It is specific to your phone, and waiting for Apple to fix it will not be productive, as it's not something that is happening to everyone. (I'm not sure where you've found a lot of people with the same problem, as this is the first I've heard of it.)
I would start by resetting the phone. Hold down the home and sleep/wake buttons for about 10 seconds, until it turns off, then release the buttons. Next, press and hold the sleep/wake button again until the Apple logo appears.
If that doesn't help, try restoring your phone to factory conditions by connecting it to your computer, selecting it in iTunes and using the appropriate button in iTunes. You can then restore data from the last backup.
If that doesn't help, it's probably a hardware issue, and you'll need to get your phone looked at by Apple.
