When I make a phone call screen goes black without taking the phone near my ear and it doesnt recover and it remains black.... While the screen is black i can hear the person who am calling to...
Yep. I had the same issue after installing the Cyanogen Mod 7.1 ROM. There is an option to recalibrate the Proximity sensor. After doing that the problem got fixed for me. So might want to try this out.
It was under Open App Drawer--> ZTE BLADE settings--> Proximity Sensor Calibration.

heyy,
im using Mdeejay_FroYo_Sense_v._2.4_Clean_S6.1 on my hd2 and when i call someone i get a black screen and i cant get out of it even if the call ends unless if someone calls me back
any ideas how to fix it ?
Hi, do you use a screen protector ?, you should not recover or clean the proximity sensor in the upper side of HD2
no
everything is fine when i use wm6.5. it only happens with android !!
Help please !!!
when you call, the head is next to the proximity sensor, hence making the screen black.
im running full stock everything for starters.
When i am in a call sometimes up to my ear or speakerphone the screen will go black and i wave my hand in front of the light sensor and nothing works. The screen stays black. I like having the lock button hang the phone up so i want to keep that option on...
Just wondering why it is doing this, thx.
Its a thing to save battery usage,
do you have a case on it?
from my experimentation, the sensor is somewhere at the top, left of the power button when the phone is facing you.
prehaps your hand, hair, or case is covering it causing it to turn off - as it should
it thinks your in a call and you dont need to look at the screen.
My defy+ proximity sensor is not working.
As soon as I make a call, the phone screen goes black. The call goes thru fine, but the screen goes black.
No, I don''t have my finger or face near the proximity sensor.
No mods on the phone OS.
I did some debugging-
Cleaned the back of the phone by blowing air.
Tried the screw loosening like in the youtube video
Changed brightness settings from auto to manual.
Changed display turn off from 1min to never.
Finally, I downloded a sensor app and checked for change in the value of the proximity sensor when put by finger in the sensor area. The value was stuck at 3%, no matter what I did.
I was playing around and when I pressed the speaker area near the proximity sensor, the sensor value jumped to 100%
So I think the glass is blocking the sensor (or acting as a reflector).
Just to make sure the glass was the issue, I made a call by keeping the speaker area pressed. It worked as expected - no screen blanking after call. It does go black if I put my finger in the proximity sensor area.
I have no idea how to fix it.The screen & sensor need to be pressed closer.
Only thing I have tried is tighten the screws in the back. But no use.
Any help?
Since you don't have mods, it's probably broken, go to customer care.
Or you can maybe try factory reset
Do you have a screen protector?
Out yes remove it.
If not your sensor is broken.

My nexus 4 Lollipop 5.1 Seems to have a problem when I make a call. I hit the phone symbol, select the number I want to call from my requent call list. I hit the dial button and make the call........ The problem comes when I go to end the call the screen goes black such that I can end the call. I just have a black screen........
Does anyone out there have any idea whats happening and what the fix may be?
Thanks for any help

The screen is supposed to go black when you make a call--or, rather, when you place the phone to your ear. There is a "proximity detector" along the top edge of the screen, and it detects your ear when your ear gets close. The phone then turns off the screen sensors so that your ear or your cheek doesn't push any buttons while you are talking, and turns off the screen illumination for aesthetic reasons. However, the proximity detector is supposed to cause the screen to turn back on when you remove the phone from your ear. That isn't happening for you. When it didn't happen for me, I took it to the shop. The tech said the proximity detector was broken, and ordered a new one. But replacing the proximity detector didn't help. He finally disabled the sensor so that proximity was never detected. that worked.
This story does not have a happy ending for me. The phone worked for a couple of days. Then I tried to reboot, and it went in to a boot loop. None of the standard cures for a boot loop is helping me. I doubt if the two problems are connected.
Proximity sensor turns off screen when you put it to your ear to avoid your skin touching the "End call" button or something else

I am not using a a "screen protector" But thanks for the input
Ok, was worth a shot...
Then you must likely have a faulty proximity sensor, as stated previously.
Download an app, like AndroSensor, and see what the output for the proximity sensor reads. When nothing is covering the sensor (top left corner) it should read 5 cm/2 inch, or something similar. If it reads 0, it's busted...

I did as you suggested and the results say 2" uncovered 0 when covered
Hmm... The plot thickens...
That means you have a working proximity sensor. No idea what it could be then.

I'll keep looking for a solution.......... It's a pain especially if if I have to respond to a VM and hit a Number.......
Thanks again
I have the same issue. In my case, the proximity sensor may have been broken or blocked by dust.
My "temporary" solution is using the power button to disconnect calls. While using a Bluetooth headset, the screen can be turned on. I hope there is a better solution.

That's what the proximity sensor is for - to switch off the screen based on interactions. It goes off so that your face doesn't accidentally touch any button and cause problems. It's normal behaviour.
Yes bro ik that but the screen should go black when the sensor is covered with the face or hand. But it goes black as soon as my phone starts ringing. I need to cover the sensor to bring the screen back up so that I could answer the call. Similarly, as soon as I start listening to a voice note received on WhatsApp the screen goes black and the volume goes low I don't know what to do I have tried flashing stock ROM then latest lineage OS unofficial latest build, any help would be appreciated

Well, a complete wipe (Dalvik,Cache,System, Data) should ideally fix such things. But if doesn't, I think your sensor is damaged. Just take it to a service centre then

Sigh, I thought so man, I was hoping it was not the case. Turning the sensor off will fix the issue but no xposed for N yet. I'll keep using this one seeing it's fine usually lol. Thanks for your help mate.
