Phone locked up on Incoming call

[willdogs]

I just received a call and while the phone was ringing, the touchscreen was completely unresponsive and I missed the call. After the phone stopped ringing the screen was responsive again and I was able to return the call.

This is the first time it happened, so not too worried. Curious to know if anyone else has seen this issue?

On a side note, the last app I used was the camera so I wonder if that had anything to do with it.

Any chance your thumb (or other object) was blocking the proximity sensor at the top left corner of the screen?

It's just a thought; not sure what impact this might have.

Same happened to me. Also on making a call and trying to cancel.

I experienced the same thing when bringing home a brand new Razr Maxx HD from the Verizon store last weekend. This occurred right off with the first phone call received and each call afterwards. I did NOT have a screen protector on either. I returned the phone the next day.

I just had my phone freak out during a call. I'd been talking for perhaps 20 minutes (home, connected to wifi) when I hear a loud chime of an incoming email notification. I was at my computer and refreshing the browser with Gmail and there was nothing new. I asked my g/f a question and didn't get an answer. I ask again, say "HELLO?", and then pull the phone away and it's on the lock screen, not appearing to be in a call. I pressed the power button and the screen went dark. Pressed again and it lit up, but it didn't respond to touches. Then it blanked out, gave the bump it does when first booting and restarted. The call log for that call doesn't show since it crashed. Very weird. Glad I've got a replacement already on order; just wish it'd get here.

I have similar but not identical behavior that occurs on every call I make or receive. I can answer a call fine, but from the time I answer until the time the caller hangs up, my screen is dark and unresponsive. When I initiate the call, my screen goes dark and unresponsive -- and doesn't come back when the recipient hangs up (nor does the call terminate)! I have to hold down the power button for a few seconds afterwards. Sometimes the phone returns to the lock screen, sometimes it reboots. I have a case (gel case that doesn't look like it interferes with the proximity sensors) and a matte screen protector, and it happens whether the case is on or off (haven't tried removing the screen protector).

Mine has locked up once or twice, but always came back. Once was when I opened the camera, and once was making a call.

Do you have a screen protector or perhaps a thumb which is covering the proximity sensor? It's the two small dots at the top left corner of the screen; it's job is to blank the display when you hold the phone to your ear.

I had this happen on my Nexus S a few times and was able to get it to respond by hitting the power button twice to turn the screen off and back on again. Then, I could swipe to answer the call. Not sure what caused this though.

Yep, that was it. Trimmed away the part that covers the sensor and it works fine now. Incidentally, I used the Proximity Sensor Finder app to check the status. Since it read 0.0cm at all times, that was the giveaway.

I AM MISSING CALLS because:
The swipe screen comes up and I can't unlock it with a swipe!

I sometimes have a problem with hanging up. If they don't hangup my screen just stays locked, don't really know why this would happen.
