Has no one ever seen this?
Kernel settings probably or sensor problem.
But you better try another compatible with your ROM kernel or search how to edit it's settings.

I used several different roms and this is always the case.
The proximity and light sensor are different. The intensity sensor sure has more sensitivity at night, but the proximity sensor has its own IR. It will work just well in both day and night.
If you have this problem on all ROMs, you might have a hardware issue. Try updating your firmware.
Happy to help.

I'm running 3.33 firmware and this happens on all roms, not sure why but light and proximity stop working at same time and they both start working when room is dark.

I updated my Xoomto 3.1 right after unboxing it. Then I found that its light sensor does not work.
Setting screen brightness to auto has no effect, it just keep the same brightness regardless of ambient light. So I must set the brightness manually, it is very annoying.
I installed some sensor utilities such as AndroSensor, Light Sensor,... but they don't display any value (just "waiting for event").
Does anyone meet the same problem? Is this an error in the sensor or a bug of Android 3.1?
(My Xoom is CDMA version)
Yeah I noticed the same thing the other day. Auto does nothing.
Could you give more details?
Did it work before upgrading? How is it now?
I'm not sure if it was doing it with 3.0, just noticed mine the other day.
Same here...
I have no light sensor issue--before or since the update.
I downloaded a sensor app and confirmed that i have no light sensor readings. I'm jusrt not sure when it happened or if it ever worked. could it be a kernel thing?
Thank you all for your replies.

What do you mean? Does it work or not on your Xoom?
Anyway, as I see, this is not a common issue, so I returned my Xoom.
Actually I take it back, the auto brightness is working for me
I didn't even notice mine wasn't working until this thread. I'm just going to go with it.
so this is weird. I upgraded to the new Tiamat kernel today and my light sensor is working again. It must be a kernel thing. I'll post a message in that thread.
Well i am very confused whether our phone has a light sensor or not. In the official user manual of I5801 (English-India), at page number 17, its clearly stated that the left one of the two sensors on top left side of our phone is proximity sensor and the right one is light sensor. If there is one, then why is there not any option for automatic brightness? and what its use is? And if its not there, then why is it given in the User's manual ?
Does anyone have any information on this at all? Was/is there any rom that supported automatic brighness via the light sensor?
So why isn't it included in Samsung' Stock Rom ?
Do you think really that no-one ever try to use it .

There is no light sensor on Galaxy I5800/5801. The proximity sensor is actually a pair of sensors, one sends an electromagnetic/Infrared radiation while the other one is to receive it back for the sensor to get activated.

Wow, this is kinda shocking news!
is there anyway to calibrate the proximity sensor on the sensation, not 100% sure thats my problem but worth a try if poss

Would like to know this as well.Proximity and light sensors not working properly on my Sensation (only occasionally).
I'd like to know how to recalibrate / get it functioning again.
Yes,i like to know that to.
Still having problems with both proximity and light sensors...
The proximity and light sensors cannot be calibrated, as they put off specific amounts of voltages based on results from the input. It is up to the ROM/Kernel to interpret the voltages from the sensors as usable values to produced the desired results. If you wish, you can download a testing program such as AndroSensor to view the interpreted sensor readings.
Hello,
After clean install Android 5.0 on Nexus 5 I have lost all sensors.
Do you have similar problem?
Is there any solution to fix it?
What app are you using? This looks like a bug in an app, than in Android itself.
I had this problem even before installed any apps. In android l developer preview I didn't have sensors also, so after installed final version of lollipop the first thing I made was check sensors. On kitkat everything worked perfect.

i don't have light and proximity sensors too...
i did full wipe and flash stock OTA
hope they will fix it soon
Since upgrading to Lollipop my proximity and light sensor also stops working after a few minutes. It works again after a restart, but only for a few minutes.
I have flashed 4.4.4 again and the problem is not present there. After upgrading to 5.0 again the problem came back.
the apps are the issue here gentlemen.
1.On call as you bring your phone to ear, screen turns off?Proximity working
2.Adaptive brightness enable and use the phone on same brightness settings in bright and dim areas, screen brightness intensity change?Light sensor working.
3.Screen rotates views?Accelerometer working.
4.Play asphalt or any other motion requiring game, car turns?Gyro working.
5.Open maps, get pointing direction?compass working.
6.Use pedometer, counter change?step counter working.

No sir, it's definitely not the apps in my case. After a restart the light and proximity sensors work as expected, but a few minutes later they stop working. I could confirm this with the Sensor Box app as well as with no's 1&2 in your post.
I noticed it first because my adaptive brightness did not work and the screen did not switch of in call. I only installed Sensor Box to see if the sensors still work, this confirmed that they actually stop working and that it is not a calibration issue because Sensor Box shows no reading from these sensors.
This is definitely an issue with Lollipop because I flashed 4.4.4 again and everything worked fine confirming that it is not hardware, but after once again upgrading to 5.0 the sensors stop working few minutes after the phone starts up.

That's interesting, have you tried any other custom roms or kernels based on lollipop? I know that is a long shot or even that best advice but could you, or have you checked on other roms?
SO only your Proximity and light sensor the issue? Or all the other sensors a bust?

I haven't tried any other Lollipop ROMs, I thought about it and I might actually give it a go to see if the problem persists on other ROMs as well, but I would prefer to have stock Android running on my phone, so I'm really hoping for a fix from Google. I'm on few other threads about the same issue, so I know there's a lot of people with the same problem. I had this on the dev preview as well.

I have tried Code-Blue kernel as I have heard it's a good one, but the problem is still there. I might try a different ROM in the near future.
For me it is only the Light and Proximity sensors, all other sensors work 100%

The Same Problem For Me As Well, My Light Sensor & Proximity Sensor Arent Working. I have downloaded the Final Image from Google Website for 5.0 hammerhead. But still the problem persists.
Nyk
After I got the Play services (with secure locations) update two days ago my light and proximity sensors are gone too. They will work for a while after reboot, but eventually they die.
All other sensors are working fine and only other updates have been to Skype, SwiftKey and TuneIn Radio.
Edit: I'm on stock OTA, no root and never unlocked the bootloader.

So uninstalling the play services update resolve the issue? I'm back to KitKat as without light sensor I find uncomfortable to use the phone. Will await the fix before moving to lollipop..

"Clean install" using factory images? I did, no issues here.
It seems to be working until I get a phone call, after that the sensors will die.
Have uninstalled the Play services update now and the phone has been up and working 100% for a little more than 4 hours now. Will try to make a phone call to see if it still works after that.

Did you reboot after disabling update?

Uninstalling Play Services and Play Store update made no difference here. Problem still persists.

Hi I have the same problems . Sensors are working after restarting my phone random time. Also you can read here
Uninstalling Play services didn't do it for me either. Sensors work for approximately 4-5 hours then they die.

Installed Play services update again after a few days and now my phone has been running fine for 50 hours with all sensors working 100%.

Hello everybody!
Recently i bought one Motorola Photon Q and I found one weird problem with my Photon Q.
I cannot regulate the screen's backlight. When it is on 100% it is very bright, but anything below this point (in example 99% or 50%) it goes very dimmed. So, basically I have two levels of backlight. Minimum and maximum. Nothing in the middle.
I tried to regulate it from the recovery mode, but issue stays the same.
Phone already had TWRP and CM 13.
Any ideas what can I do about it?
Regards.
Wow you joined in September 2008 and this is your first post?
Congrats!!
As for the issue, it almost sounds hardware related. Like someone swapped the proximity sensor for the ambient light sensor... If the issue persists in recovery, I'm not sure flashing stock would do you any favors (not that you would want stock, it would just rule out any low-level software issues if you flash thru RSD Lite).
Yes yes, I know. There was nothing I could give from my side. Just usual user.
Changing the sensor? But does it have anything in common, while backlight sensivity is chosen manually?
I'll try to flash it by RSD lite.
Thanks.

Honestly was just firing off the hip based on you description - it sounds hardware related not software, especially since it persists in recovery...
To rule out software entirely, RSD Lite is the best way IMHO. Good luck.
Assuming it is a hardware issue... I'm not sure replacing that sensor is worth the effort. I guess it depends on your desire (and ability) to get this old PQ working properly
It might be the hardware problem. I installed some application to check sensors, and it does not detect proximity sensor.
I was wondering about dismounting this sensor, but probably it would not help at all.
