Proximity sensor not working correctly...screen won't turn back on!

Alright so I'm loving my iPhone 4, but I've been having one glaring issue: the proximity sensor turns off the screen during a call(as normal) but then the screen won't turn back on until I lock, force hangup and lock again. Very frustrating because I was unable to dial a number to be transferred while in a call. Seems like the same issue is going on with other iPhone generations upgrading to iOS4 in the other forum sections, but I'd never think it to happen with a brand new 4. Could it have been my restore file from my 3GS?

Anyone else having this issue? Thanks.

Mac Pro 2.8 Octo, Mac OS X (10.6.4), iPhone 4 32GB

Same thing is happening to me. phone works great but when on a call proximity sensor kicks in turns off the screen. When I pull the phone away from my head screen is still blank. The force hangup/lock is the only way to bring the screen back on.

Maybe this is something having to do with the upgrade from os3 on my old 3g

anyone figure out a solution?

If resetting the phone from Settings -> General -> Reset -> Reset All didn't do the trick, try doing a hard reset: at the same time, press and hold the home button (bottom of the phone) and power/sleep button (top of the phone) until it restarts. That seems to do the trick for almost everyone.


Will doing the hard reset lose all my settings and data, like the erase iPhone option?
Or will it just reboot it keeping all settings etc?

Many thanks.

I just did a hard reboot and made a few calls. The proximity sensor seems to be working better. I will check the bluetoooth connectivity in my car tomorrow which has also been suffering.

I was told once by a mac genius that you should periodically do a hard reboot because of all the loading and off loading of software on the phone. Also, once you install a bunch of new apps you should do a hard reboot.
