Hi,
This week I'd noticed a little problem with my XP, when I unlock the phone, or remove the phone from my face after a call, there's a backlight lag of about 10 seconds. The screen is responsive, but I can't see a damn thing on it.
Who can help me?
This problem is most likely to be because of a damaged proximity sensor or light sensor. It also could be because of a damaged screen but I wouldn't count on that. Hope this helps!!!

Is there any way to test these sensors?
edit: I'am going to try this: https://market.android.com/details?id=ctsr.android.SensorTest&hl=nl
They don't show up in this test.
Maybe this is 'cause I've turned off auto backlight using some sort of script?

Hi all,
My light sensor appears to be broken on my phone, I put it to my ear when making a call but when i return the screen is still black.
The screen does not return to normal till the other person hangs up (anserwing mchines are giving me the rage lol)
Does anyone know how to fix it? or just turn that function off? Not sure why its suddenly broken.
cheers for your help
yes go to settings and screen disable auto light
Could be an issue of your Rom...
you can check if it is actually broken with this app: http://forum.xda-developers.com/showthread.php?t=951858&highlight=proximity+recalibrator
Take a vacuum cleaner and vacuum on the top left of your screen,around the screen seal, small dust particles can get in there and affect the light sensor. It worked for me... give it a shot!

Added some basic testing how-to. Let me know "ok" or "not ok". I will have to return my phone today if this is not a generic issue
250 views - no responses from the nexus owners?
anyhow, just realised LIGHT sensor works in daylight (at least from 10 to 160 lux). However, still no cookie on the proximity sensor - can anyone confirm or deny please?
My prox sensor works just fine. Not really had chance to check the light sensor as Ive only just bought the phone and had it set to full brightness. Ill post back shortly..
mine seems to be functioning fine here.

Right then i can confirm the light sensor works in mine too in daylight
Proximity sensor not though... anyone else?! this is really strange
Both work on mine.

Mine is OK as well.
Mine seems fine for both
Both work perfectly on mine! For the proximity sensor, try it during a call! It might be trivial but just saying.

AndroSensor says both work but auto brightness (auto dullness?) is useless and I triggered a keypad press while on a call...

see - thats exactly the point. The sensor does NOT work (on mine)
Proximity Sensor - will switch display off to avoid the keypress or other issues while on call when you are holding it to your face(ear). And re-enable display when moved away from the face
Autobrigh: measures ambient light and then adjusts brightness accordingly
you may have both confused?
check with AndroSensor:
proximity sensor - cover it with your hand (next to the front camera) and the values should change in AndroSensor - but they dont. neither does the display switch off during calls when detecting your face (actually just detecting "no light")
I will return my GN. I had enough.
The light sensor works according to AndroSensor but auto brightness simply dims the screen to a useless level. Likewise proximity sensor works (values are either 0 or 2 inches) but whilst the screen does indeed dim during calls key presses are still possible infuriatingly. Software fix would cure both.

Light sensor works fine.
Proximity sensor does not work. I think it stopped working after the volume fix OTA.
For my device, the proximity value changes fine however the screen doesn't turn on off when answering and ending a call. hv to lock the screen and unlock the screen manually to prevent mistouch..
Just tested and the screen turns off just fine for me on a call.

I know this topic is kind of old, but I'm still having the proximity issue, do you think I should return my nexus?
Mine doesn't work either, since 4.02 I think. Are there any settings that should be enabled for it to work like gprs or location services or is the proximity service always running?

Dear all,
Seems some dust is stuck up on my i747s proximity sensor. I will get it cleaned at a later point, but for now I need to disable the proximity sensor. The phone screen just turns off as soon as I dial a number and wont come back up until the call has disconnected. So cannot access the screen while on call.
I am rooted and on CM11 (kitkat). So do not have the TW option to go and disable proximity sensor in call settings. There is an option to disable the driver using hardware disabler app but I found by searching that that is causing a lot of battery drain. Anyway if someone knows the driver name and location for the proximity sensor of i747 then please do share that.
I have tried a couple of sensor test apps and all report that the sensor is active but it has something close to it so basically the sensor is always thinking that its close to the ear.
So need any ideas to disable the proximity sensor completely or at least from being invoked as soon as I place a call. Thanks for any help.
Do you happen to have a screen protector on that's covering the sensor? It can cause the sensor to think its covered. Thus having your screen always off

Thanks for your reply. No Screen Protector on my phone. I have gone through a lot of search results and screen protector has been a common culprit but after hours of searching I think my only option is to disable the sensor. Long term I need to open the thing and clean up the sensor.

Bump...please help!
Does anyone know with which application to do calibration proximity sensor on E988?
I tried these hidden codes
3845#*988#
5457#*988#
3845#*980#
5457#*980#
3845#*240#
5457#*240#
and none of them fit for e988.
The problem is that when i place the phone on my ear screen turns off,and i move phone away display not on. I tried all possible ROMs and hard reset and no help...
You can go to your build.prop and change your proximity delay that way. Or I know vanir and some others have the option to change that.

I tried that,nothing. I think it is hardware problem. When i press pleace on display in the top right corner sensor starts woking. It works for a while,5-6 minuts and then again the same problem occure.
Is it possible to solve this problem without replacing the whole display?

Hi guys, am i the only one with this strange behaviour? Phone screen unlocks when in pocket, seems like it is sensitive to the touch of my legs. Can i prevent it from unlocking?
Put the screen facing outwards?
Sent from my ASUS_Z00AD using Tapatalk
Same thing happens to me. They should prevent the screen from waking up when the sensor detects something close to the phone like LG does
Happens to me, I put it facing outwards. It seems to happen when there's a notification and the screen lights up.
Sent from my ASUS_Z00AD using Tapatalk
Same for me, but put the screen facing outward isn't very comfortable in the pocket.
Maybe enabling the sweeptosleep feature instead of double tap to wake is can help to solve the problem, but i don't want do unlock the bootloader.[emoji52]

It's sweeptoSLEEP, not sleeptowake, so it doesn't help.

No, or at least it didn't when I tried it.
You can actually use the proximity sensor to decide if the device will wake or not with doubletap2wake if you're using xposed with GravityBox. So if the sensor detects something's in front it won't wake. But expect some delay to wake your device.
Sent from my ASUS_Z00AD using Tapatalk
I turned off the double tap to wake feature and haven't looked back. It was never cnsistent for me anyway; sometimes I would need 4 or 6 taps altogether, with delays to see if it worked. The button rarely misses.
i had same problem.decided to remove double tap to wake.

This may help, or you could enable a pattern or pin for the lockscreen.

Tryied but it opens the emergency call dialer and send calls... lol
Moreover, type the pattern every time i have to unlock is very annoying.

Completely understand. I've tried taking my phone out of my pocket without any issues (the screen is still black), I also have double tap to wake enabled, but haven't experienced the problem. I'll bring it up with our team.
If i cover the phone sensors with my finger, dttw doesn't work, so it shouldn't work in the pocket. It's proximity sensor related.

I just tested and covering the sensor does in fact stop it on my phone, and yet I'm still getting random wakes in my pocket. I know it's dttw because I feel a short, single vibration, so I don't know what's going on.

turn off double tap to wake is a nightmare with zen 2
leave it on and get used to it

I have found that the thickness of the lining of my pants pocket greatly affects whether the phone turns on. If the pants are loose and the phone can bounce aroudn a bit is even more likely. Jeans are never a problem, but my suit pants are always a problem.
