so this just happened out of nowhere. it's never happened before. but now it happens on every call.
the second i make a call, the screen turns off and it doesn't come back on until the phone call is over. i push the power button and the screen would momentarily turn on but it goes back to black in a split second.
anybody have a fix for this?

This is usually caused by something obscuring the proximity sensor such as a screen protector, dirty smudge or more commonly dust particles under the screen. If it is dust then give the ear piece a couple of strong blows or use a can of compressed air if you have one. You might want to submit your phone for repair if a lot of dust is gathering under the screen. You can tell this by looking at the front camera to see if there are any dust particles in there.

I seem to have the opposite of this issue, my screen isn't turning off during a call at all (so I can press stuff with my face).
May just have to take it to a Nokia Care, so many issues!
EDIT - cancel that, managed to try out a load of different suggestions and got it to work (uninstalled Skype?, took a photo & video with the front camera and soft-rebooted), was probably the reboot that did it tbh.

The black screen (or blank screen) is usually from a build up of dust, blocking the light sensor, which comes in from the earpiece and headphone holes. If you look at the phone in bright light you will be able to see dust around front facing camera. The light senor is hard to see which is just to the right of the camera. The collected dust makes the phone think that it is close to your face, which in turn simulates reduced light in the sensor and the phone thinks that you are still on the call and the screen stays blank (to conserve battery and keeps your face from randomly pushing buttons).
So, to easily fix the problem, hold the phone in bright light (so you can see the dust) and used compressed air to blow out the earpiece hole, the headphone hole and the area of the screen between the glass and the case close to the front facing camera. You will see the dust disappear and your phone use should return to normal operation.

I have the same issue caused by dust under the screen where the proximity sensor is. My camera on the front is also very poor quality due to the dust now. Nokia should have known dust would get in nearby and sealed the camera and sensor areas to prevent this issue since it will compound over time and continue to get worse. I bet most people experiencing this issue put their phone in their front pocket facing down and the lint and dust accumulates. Women using purses are probably much less likely to have this issue. I will be exchanging my phone and have it noted on record since I can see this happening every 6 months at so unless they modify the design.
