Touch screen going out during a call?

Is anyone else having this problem? The screen goes black during a call and does not come back on when you move the phone away from your ear or if you slide the keyboard out or touch the screen. No matter what I do, the screen doesn't come back on but the call is still active. It seems to be happening with inbound and outbound calls that involve an automated system. It's happened about 5 times since I got the phone June 6.

For example, tt happened last night when my dr's office called to confirm an appointment (inbound call). The automated call asked me to hit "1" to confirm my appointment, but the screen was black so I couldn't tell where the "1" was, and couldn't get the screen to come up (and I didn't think to use the keyboard-duh), so my appointment was cancelled 

It also happened when I had to call my husband's doctor and needed to enter an extension #, but the screen was black so I couldn't hit the ext. # and I couldn't disconnect the call (outbound call) and the message just kept going in circles.

It has happened a few other times. I already had to replace the phone once, it died the second day I had it so Sprint did replace it but they had set it up wrong (had mine and my husband's phone #'s mixed up) so it ended up taking an hour.

Sorry so long! Just wondering if anyone else has had this problem, I'm going to take it back to Sprint this weekend and see if I can get a new one.

No, no case or anything.

I have the exact same problem-- seems like I add to my problem list daily-- on my second phone and soon to be third but best buy hasn't had another shipment yet

mine does it and I thought it was normal.

when I pull the phone away from my face the screen lights back up.

Hey thanks, ppf.

One more Q, when I am playing pandora, every time a new song comes on the screen lights up showing the artist and song, then fades away, but my husband's does not light up at all.  Is this an issue or are our phone settings set up differently?  I've tried to put both phones next to each other and compare the settings but see nothing different.

I was google-ing and came across this thread because I has the same problem with my pixi.  Every time I make/receive a call my touch screen would go blank.  It made me think there were problems with my pixi.  I got the phone about 3 weeks ago.  Until I have my screen protector, I was hesitant to take off the film screen protector that came with the phone.  The top part was peeling and it had dust on the film.  I was trying to figure out how it keeps going blanks on calls and when it went blank again... I lift off the protector from the sensor (IR look-a-like-thinging) left of the phone speaker.  My screen came back on again.   

So make sure the sensor is clear of dust or other stuff that may block light.
