When I make or receive a phone call on my new Nexus the screen blacks out. I understand that it should black out when the phone is brought up to my ear, but it blacks out even though the phone is eighteen inches away from me. There is nothing on top of the proximity sensor and it is clean. The phone is not in a case. The sleep timer in set to two minutes. The cache partition has been cleared.
I think this happened after upgrading from Android 5 to 5.1, but I cannot be certain.
The AndroSensor app always reports that the proximity sensor detects something at 0.0 inches (with 12.7 mA), even though the sensor is uncovered.
I have seen several threads in various forums on this issue with the Nexus 5, but I have not seen a definitive answer as to what is wrong and what can be done about it.
Help would be very much appreciated as I need to know if it is a software bug that will be fixed as part of routine updates, if it is a user fixable problem (operator error!), or if the sensor is actually dead, in which case I can exchange the phone (Amazon uk).

Thanks for this, but if the power button it set to end the call it does indeed turn the screen on again, but of course also ends the call prematurely. If the power button is not set to end the call, then nothing happens when it is pressed during a call and the screen stays black. The only way out of the black screen under those circumstances is to hold the power button down to turn the phone off and then restart it!
Prior to the upgrade 5.1, from the version of 5 that came with the phone, when I made or received a call the screen remained active until I put the phone to my ear.
Further advice would be much appreciated.

if i make or answer a phone call, and put it on speaker, after a few secs it will turn the screen off automatically. If i then press the pwer button (i don't have the accessibility option on), it WILL wake the screen but doesn't end the call.

Thanks for this, but the problem was that the screen blacked instantly on making or receiving a call and was unresponsive, so the only way forward was to press the power button. This either terminated the call or shut down the phone, according to how it was set, so neither was useful.
As I said originally, I suspected the proximity sensor was faulty as the a proximity detector sensor app always indicated that there was something close to it. Hence the phone would assume it was next to my ear when making or receiving calls, and so black the screen. This morning, for reasons that I don't understand at all as I have not changed anything on the phone, the proximity sensor is reported as working and the phone behaves as it should on making and receiving calls!
I suppose that either the sensor has an intermittent fault, or something in the phone's software has changed to permit it to work. I have a couple of week's left before the Amazon return window expires, so I will monitor the situation.
Thanks once more for the help.

I have the identical problem with my nexus 5 running stock kitkat. Makes it very hard to use the keyboard to reply to automated requests to "if... press 1, if.... press 2".
Is it possible to turn the proximity sensor off? I don't need it and it just causes problems for me.

Does anyone know if there is an issue with the proximity and light sensors in the Samsung Focus v1.3? Neither of them work on mine.
When I go into Diagnosis, the Proximity Sensor test shows XXX where the detection value would be, and the light sensor says "Val: 0000" in red where the ambient light value would be.
This means whenever I make a call, I have to hit the sleep button on the phone to turn the screen off, lest I accidentally press buttons on it with my ear while I'm talking.
All other features and functions of the phone work just fine. I've dropped it once, but the Prox/Light sensor issues started occurring before that.
Any assistance would be appreciated.
Might be a hardware issue i have the same problem, i tried to fix it by installing the factory ROM. No luck. I'm gonna bring it back to rogers to see if i can get it fixed :\
Similar problem
My phone will go to blank screen as soon as I hit "Answer" or for outgoing whet I tap "Call" so I can't put on the speakerphone or hangup. All butons and functions are disabled. I have to remove the battery to reset the phone or wait for the caller to hang up. On calling "VoiceMail" it just goes on and on before hanging up so removing the battery works faster and restarting the computer.
I have tried to adjust the proximity indicator as I read on another forum but it doesn't seem to make any difference. I have to add that this seems intermittent and sometimes it works normal and sometimes not.
Maybe "dropping it" has something to do with it. One forum said customer service wanted him to do a hard reset which I assume is the only way to get rid of the Mango update or any apps installed that may be a contributing factor. If anyone has any ideas let us know.
Not sure if any of you had this but I notice my phone when placed on speaker mode, after calling my screen goes blank and none of the key function work (all buttons including home, power, etc) and I had to do a battery pull. I assume this may not happen as often but I recently get it a couple times already.
I spoke with the S2 guys and notice this happens to their handheld due to the sensor set. One best way to work around is simply Turn off proximity sensor under Call setting.
This happen when I had a 2.3.6 TGY KK5 stock rom.

yeah buddy same thing happens with my device as well.. bt it doesent always have to be on speaker mode. on normal mode also sometimes my device goes blank..
anyone here help please.....
Several users on our russian forum have reported same problem on different ROMs (2.3.4, 2.3.5 and 2.3.6). Most of them are using phone calls about 60-90 minutes per day.
I never had this issue with my 2.3.5 Germany ROM, but I am using my phone for calls just for 5-10 minutes in a week.
Tip
You don't have to replace battery. Just long press power button (over 10 seconds), and phone should reboot.
I've seen the same problem on my phone, but after I pressed the power button for about 7 seconds and let go, the screen came back and I was able to hang up the call. I've turned off the proximity sensing (settings -> calls -> proximity sensor) and haven't seen the issue since then.

okk i wll give it a try........
my gf is experiencing this issue on her SGR as well. After a call, the phone will become unresponsive and the red spot(light sensor) near the speaker at the top of the phone will be lighted up.
using stock + ardatdat's 1.3A kernel (default settings).
will try the proximity sensor solution and hope the issue goes away.

yes buddy after unchecking the promixity sensor in call option it 0does work... bt still sometime red sensor glows and slows my phone down..... if anything of this kind is experienced then do share..
should be fine once you switch the proximity sensor off as thats what it seems to cause all the prob and the only thing u have to live with is ur screen doesnt go dim when you stick it to ur face while talking
The problem is like this:
SOMETIMES when I call someone, the screen turns off without approaching the phone to my ear. The screen is not turning off by pressing the power button or the volume buttons (I enabled using GravityBox to turn on the screen using the volume keys).
After I end up the call, after a couple of seconds, the phone comes back to normal.
Once again, this behavior appears just SOMETIMES! Usually I don't have this problem!
Any ideas to how so solve this problem?

I wouldn't worry too much about it, its just a glitch, it happens to me sometimes too , when i put it on speaker and i get close to the phone , the screen turns off and it comes back after a while. it doesn't bother me too much. It might be that the sensor is too sensitive. Have you tried a custom rom ?
This issue happens to my son's phone too.
Anyway, it shouldn't be random, please double check if it happens ALWAYS after a phone reboot, this is the behaviour of mine
I want the moderator to ban me.
display issue
Hello,
I have started to face the same issue mentioned above.
On googling I came across the motorola forum (google search: Moto G Proximity Sensor Software Issue)
It seems the issue is being discussed there and apparently they need more moto g users with this issue to help them out solve this.
On using z device i noticed the proximity sensor value stuck at 3 with no change covered/not covered (sensor) [Phone running without restart for 6+ hours]
After restarting the phone the sensor value in z device changes. 100 (uncovered) to 3 when covered.
I will keep checking this every few hours to see when does the proximity sensor stop working without restarting the phone. (uptime)
Can the DEV's here help us out? looks like Motorola may take some time in finding a solution to this issue.
This seems to have went away with 4.4.3 and the new Dialer app.
I've had an odd problem with my 820 almost since getting. I'm hoping one of you geniuses have some advice.
When I turn it on it works perfectly, sometimes for hours. Then the screen goes blank, and then random pixels begin to appear, starting at the top of the screen. Outdoors rather than random pixels the screen goes almost totally green. Strangely, if part of the screen is obscured the green only covers rhe exposed area.
Pressing the on button repeatedly usually brings back the lock screen and reset (on+down) fixes the problem for another few hours.
By the way, eventhough I can't see the screen the touch sensor works. For instance I can hold theon button and then swipe downwards to turn off the phone. I can also answer and hang up using earphones.
My daughter who purchased the phone said it worked fine until the amber update. I had hoped the black update would fix the problem but no change. I found some posts from people with the same problem who sent the phone in to be fixed and got it back in the same condition. I really don't want to go through the hassle unless I expect to get it back fixed. I'd rather try fixing it myself.
My question is whether this is a firmware problem an whether it is likely that re-installing the stock black rom would do any more than the ota install that occurred automatically did (or didn't do).
Any ideas?
Nobody?
By the way it seems to happen only, or mostly when in standby.
I installed an app that displays a clock and doesn't allow the phone to go into standby mode,
and the problem doesn't appear to occur (unless I forget to leave the app on top).
I would set the phone to standby = "never" but the option isn't available on my phone, though
I understand that there are those with the standby = "never" option.
Any idea if I can set standby = "never" with keyboard commands, perhaps?
Good morning, i have a Note 20 Ultra exynos version and when i test the proximity sensor i have no response. It's possible ??
Thanks
yes, it is implemented differently. it works fine with apps that support it
What do you mean by "test"?
When you're on a phone call it should turn off the screen if you cover the sensor.
No if i cover the entire note the screen is always on.

Using the mic not in speaker phone mode?
If so it sounds like it's not working... phone screen should go dark when it's against your face on a call.
Try clearing the system cache on the boot menu, this may fix it.
Try it in safe mode for the off chance a 3rd party is the cause.
When i try with a call it seems to work but after two or three attempts the screen remain on also if i close the cover..

Not sure but that sounds like software.
You said cover as in a wallet case?
There may be a setting for that but if so I have no clue.
Doesn't sound like a normal operation unless it's a Samsung case and it's suppose to do that.
Don't think there's even a visible specific system apk for it. You could try clearing the Android Systems cache maybe data too but that may cause more trouble with lost settings... and end up worse off for the trouble.
On the note 10+ a small faint blinking circle is visible about a quarter inch to the right of the front cam cut out when the proximity sensor is active. Not flashing, not active.
If that helps you any...
Note: if it's active during a call and I trip it 2-4 times with a second or two spacing, the screen will remain off until I turn it back on.
This is normal operation.
Ok thaks a lot for your explanation..
I'm having the same issue which started today. Every time I put the phone up to my ear to place/ receive calls the proximity sensor isn't working and I'm pressing all random buttons accidentally with my cheek. I've turned my phone on and off to try to get it to work and no dice. It was working fine before today so I'm not sure what happened. I didn't drop my phone or anything. A google search showed this has been a problem since the S10 when Samsung embedded the sensor under the screen and dropped to turn on/ off this feature under call settings.
Advice anyone?
Try in safe mode. If it works there it's most likely a 3rd party app.
Was -anything- updated or just installed?
Did you change any settings?
Try a "hard" reboot and clear System Cache in boot menu.

Is a hard reboot restoring everything to factory settings? If not can you provide me the steps I need to complete to get there and If I need to back up everything and how to go about doing that? I'm a novice who's learning everyday so I appreciate your patience

No! Not a hard reset!
Hard reboot simulates pulling the battery...
I think I got it to work again. Hard reboot I guess according to google is pressing the “Volume down” and Power / lock key for 10 to 20 seconds bypassing the options shown on the screen until the phone turns off by itself. I then pressed the volume up key and the power/ lock key until the android recovery menu came up on the screen. I then chose "wipe cache Partition" and rebooted the phone after that.
It seems to be working again and hope this helps anyone who starts encountering this problem like I did.

Clearing the System cache can fix a lot of Android voodoo gremlins. I clear mine regularly or if the Android is acting erratically.
Hello
I am the owner of a Note 20 Ultra starting today.
I previously had a Note 10 Plus, where the proximity sensor showed as a blinking white light near the front camera.
At Note 20 Ultra there is no sign of its presence, no blinking light. Is this normal? Can the real owners check and confirm?
I also checked with secret codes:
Using *#0*# and selecting Sensor opens a menu where I cant find any proximity sensor
Using *#77692# opens a window with proximity and light sensor; for proximity sensor I turn on and wave my hand over the front camera area, it vibrates and turns display green each time, but after several attempts (7-8) it stops working.
So, is this normal? It has a new algorithm or type of sensor?
Please check and confirm.
Thank you

Its possible that there is no sensor, I have not done any research on this but it is possible to use front camera as proximity sensor. It would mean that the function would activate when you are on call and not on loudspeaker, it should not be tough to implement.
It has a discreet proximity sensor...

I have seen this article but it is useful only to locate the proximity sensor. But regarding how it is actually working, there are no details.
I was expecting something similar with Note 10 Plus but there was no blinking led/pixel to be found when having a call.
And honestly, I am not very impressed with its functioning. When using phone on left ear especially it skips activating many times.
Also, during a call (normally not on speaker), when I cover the top of the phone with my hand, the screen does not go black instantly (I must keep it covered about 3-4 seconds) but if I puck up the phone to my ear it seems to activate, which makes me think it has an algorythm that includes other sensors like gyroscope. Or maybe my proximity sensor is faulty... but as I said, if I test it with proper code, it seems to be present and work.... Which makes me thing it is a software problem.
So, I come back to my previous details and kindly ask other Note 20 Ultra users to replicate similar behaviour.
Thank you
My note 20 Ultra sensor works fine if the speaker is off. Turn the speaker on and the proximity sensor is disabled.
Try using this code in dialer.
*#77692# and then turn proximity sensor on and put hand over top part if it lits up green then it's working as it should. But if it remains white and nothing happens then there is an issue with sensor.
