Hello!
After I got my phone back from repair with new screen and motherboard i have got this annoying problem when taking calls, screen goes on and off, sometimes stays off when I try rotate it during a call.
Any ideas?
The phone using proximity sensor to detect your face, for the case if anything get cover/near the sensor (under 9cm; located left to the htc logo) during call the screen will turn off and disable touch screen too. This meant to avoid user accidentaly ends the call. Please note that there is also a 0.5-1.0 second delayed for the screen to turn on/off based on the sensor.
If you phone's problem is on the case, then it is nothing to wrong.. else please elaborate briefly on the issue..

Noticed recently that When a phone call is in progress, the screen will go black no matter what and to get it to come back i have to manual hit the top power button.
I first noticed it with energy rom. When autobacklight was enabled, their was no getting back to screen at all. Disabling autobacklight at least allowed me to get the screen back after clicking the power button.
I switched to core cell rom and noticed the same issue, however, i can manually turn the screen on again even if autobacklight is enabled.
I have no further problems with the proximity sensor, just this one.
Is their perhaps some sort of proximity app that i could use to diagnose whether this is a hardware problem or software problem?
Ok, I had a similar issue, where the phone screen would turn off as soon as the "send" button was pressed, and the only way to turn it back on was either hanging up, or waiting till it felt like coming back on.
My proximity sensor was stuck "on". I could see the sensor status in the registry (don't remember offhand the reg entry, but it's a live reading of the sensor, 1 or 0). I installed "Proximity Sensor for Screen Off v0.2" from http://forum.xda-developers.com/showthread.php?t=624206
That was a mistake on my part, though... then the screen wouldn't come back on! It took some real finagling to get the screen on.
To fix it (temporary? permanent? dunno...) I waved a small neodymium magnet over the sensor (near the ear speaker). I have no clue why that worked. I don't know why it stopped. I *definitely* don't know if that's the issue you are having. But it's worth a shot
I've never had this issue after many different iterations of the Energy ROM.
Do you run Task29 when you flash ROMs?
Yeah i always task29. I don't believe it is the rom since i have tried another rom and the problem persisted. I tried the magnet idea but it didn't work. It was a refrigerator magnet though so i didn't expect it to. Anything else that requires the prox. sensor to work, has no problems and that is why this is weird to me.
Hey guys.
I have a desire which has been dropped and the screen in the top left corner cracked. The proximity sensor is damaged, and I can test with various apps that this is indeed broken.
Now, when I get or make a call, the screen turns off, but since the proximity sensor isn't working, it's not turning on again when I move the phone away from my ear. So I wanted to know if anyone knew of a way of either completely disabling the feature, or a way of manually "waking" the screen again, by using any of the hard-buttons?
Thanks
what happens.. when you press power button
Sometimes it comes on, but mostly it doesn't... Regardless of which button I press...
I have read somwhere.. that by blowing some air over that part.. may clear any blocakge.. and proximity sensor works fine.. just try this .. use any vaccume cleaner.. and blow some air over sensor part..
And if that doesnt work.. search for this app in market "'Proximity Screen Off' ".. it might help you.
Yeah, I read that too... Tried blowing with compressed air even. The sensor is dead :/
Try this app.. it will switch your proximity sesor off after call ended.. its not mine just found. you might wanna try this

Hy, i have got the same problem !
Hi;
While on a call, the screen will close. While still talking I press the side button to open the screen and the call will disconnect.
How do I correct this?
Thank you.
Same question. Its just stupid, how on earth I`m supposed to wake up screen without disconnecting a call ?!
Go to: settings>Accessibility>un-check-power button ends call
what's funny is i'm pretty sure that this setting is not selected out of the box, so you guys must have went and enabled it yourselves!

I don't know about yours but my SGN seems to have proximity sensor near the speaker and it seems to turn screen on as soon as I take it away from my ear auto-magically It may "lag", but it's fair enough for me...
Mine did the same thing today. I confirmed the accessibility link cited above was not checked. Proximity sensor is irrelevant, I was on a two hour conference call and speaker using speaker phone mode. Screen times out and shuts down on its own, which also shuts off the prox sensor.
I have a slight issue with my GSM GN.
The problem happens only when I am on a call ( sending or receiving).
When I am on a call if I am requested to , let's say, "press 1"
I bring up the pad to press 1 and before I can press 1 the screen becomes black, comes back to normal and goes back to black before I had a chance to press 1 again.
And it becomes a missed call.
I also noticed, again when I am on the dialer, during the call if I put the phone to my ear the screen again turns black until I get it away from my ear.
If during this call I put the phone on my desk the screen turns dark.
Back to normal screen when I lift it from the desk.
I would appreciate any input to help me understand this weird behavior.
I believe it is the proximity sensor that determines when to turn the screen on/off during calls.

What would be the course of action in this case?
Does somebody has a solution in mind?:fingers-crossed:
Usually proximity sensors help save battery life when making a call turning the screen of assuming that you have your phone close to your ear. But if you want to disable the sensor figure out a way to block the receptor of the sensor, as it is confirmed of two parts. The emitter and the receiver. If the receiver doesn't get a reflection of the emitter then
The screen won't go off. Hope I explained myself

Note 2 Verizon Rooted. Two weeks ago my phone started this. When ever I make a phone call, the screen cuts off. The problem is it wont come back on until the call has ended. Now if i reach someone this isnt a huge issue, but if I have to deal with an automated system, or get someones voice mail i Have to do a battery pull. Does anyone know what is going on? Please help.
Try to clear data of phone app.

Same Problem
I had the same problem, I found it was the cover I had on my phone that prevented the phone to go back on during a call.
This is a problem related to the proximity sensor. It's something very hard to clean so I just disabled turn off screen during calls option. Just go to your dialer press menu button then click call settings you should see turn of screen calls option, disable it.
Your cheek probably touch to screen and press random buttons when you're on the phone so remember to turn off your screen by on off button so you dont touch buttons with your cheek.
Hope that solves your problem
edit: I found that sometimes blowing through the speaker makes proximity sensor work correctly for a while. It's not a practical solution though.

Thanks for the information everyone! I busted the screen a few months ago and assume that's whats causing it. I just didn't think that was it because it hadn't been a problem until well after I busted it. Ill disable this option and that will take care of it for my needs.
