Hello everyone, din anyone else experienced problems with the light and the proximity sensor? On my SGS2, after few minutes of intense usage (usually after surfing on net via Wi-Fi, when phone gets hotter) the above sensors get stuck.
More precise, using a Sensor Tester, the light sensor shows either 0, either 16000, whilst the proximity sensor doesn't update values at all (stays at 0) when putting the hand near (or on it) and taking it away.
Again, anyone else experienced? Might be a faulty unit or is it a general behaviour?
Thanks!
Bogdan M.
I have the same problem but with the proximity sensor only
I sent it to warranty, next week I will see the resolution. Hopefully they'll replace it as faulty.
cheers.
Same Here
Sames Here, went back to warranty still waiting the answer
Ya me also facing the same proximity sensor issue from the last few days. the sensor is not working during a call. It started after I updated a game (diversion) and the facebook app from the android market. god knows what is the reason. Tried DHD proximity Recalibration yesterday. it says Kernel not found "- ps_kadc not found.
I will try to reinstall all the firmwares using kies today and see if the problem get solved. will let you guys know

I have my SGS2 since two weeks and very pleased with it. All worked fine, also the compass or magnetic sensor.
I tried some custom ROMs but now use the original KE2 again. Since a couple of day I noticed that the magnetic compass does not work anymore. No movement at all. Also checked it with other apps (Google Skymap etc) but no compass.
I checked the sensor with code *#0*# and then select the sonsor tests. It shows MAGNETIC Sensor "Need for calibration" and the needle is stuck and indicates 0 degrees.
I have been trying to callibrate in many ways described on the net but without luck. Does anybody have an idea? or is the Magnetic sensor bad/damaged and should I send the SGS2 back?
Search works .

Mine is only a few degrees out. Using Stock KE7 XEU Rom.
Not too fussed tbh.
Magnetic sensor
Well, I read all what has been written on the magnetic sensor or compass on XDA developers and other forums. Learned a lot but nothing helped.
I would like to know a way to check if the sensor is bad.
I downloaded the compass app and checked my sensor.
I tried the program "Sensor Test / Plot" to check the sensors. No values at Magnetic field, Orientation, Gravity Sensor and Rotation Vector Sensor. It just says "Waiting" as the program probably does not receive any data.
Until now I beleive it is a sensor problem and not calibration. It could be a problem in the firmware as it occurred after flashing some ROMs. I tried all origianal Samsung ROMs again but without result, the compass stays stuck and phone doesn't know it's orientation.

Just downloaded the same app and all ok here.
I don't know what happened today but suddenly the magnetic sensor came alife. The test program is now giving readings and senses magnetic influences. Also the compas is showing some movement but is pointing always wrong. North is always down (towards me) and south always up (so compass indicating 180 degr). Rolling the phone causes the heading to change.
I tried calibrating the compass using several described methods and compass programs but without luck. I get tactile feedback of good calibration after figure 8 waving (using a standard compass program). When I start the app it notes that it senses an abnormal magnetic field and needs calibration.
I'm happy that the magnetic sensor seems to work again but I can't get it calibrated.
Problem solves, it was a bad magnetic sensor this time. The phone is under repair and I will get a new board inside. Hopefully I will have it back next week.
Problem indeed solved. Got the phone back with a new magnetic sensor

Dial *#0*#.. select sensor... then hold ur device and move it in air so that it makes an 8... do it a couple of time... it will solve your problem...
Right after I replaced the rear camera in my phone it seems like the proximity sensor died as when I try to call the screen immediately turns off and locks until the call has ended.
Proximity sensor finder indicates that there is an object 3cm away but there is nothing actually there and the indicator is just stuck on 3cm.
What should I do?
I'm on cm9 btw.
Bump
Same issue
I have my stock camera and run CM9 AOKP, and I have similar issues with the proximity sensor. I read somewhere that it was an issue with CM in general and always discounted it as such. I did set up volume rocker wake and use that to wake the screen on call.
Do you use facelock? Try disabling it. Its a well known bug in CM9 that effecting proximity sensor...
Sent from my MB860 using xda premium
Using the volume buttons doesn't wake the phone.
Note sure what facelock is.
Thanks for the answers.
my wifes proximity sensor started acting up along with many other problems. this all happened right after the last OTA update. I sent it in to moto for repair. I was suprized i didnt need a reciept. I bought it on cl used. went to motos site and they showed me how to check if warranty was still good
Phone was imported so no warranty is available.

Ok, I figured and putting the proximity sensor really close to a light source makes the screen wakes.
Also, using proximity sensor finder I did see that the proximity sensor responds when putting it really close to the light source.
It seems that while replacing the back camera, the rubber cover of the proximity sensor fell off. Is there any way I can replace it or improvise something that might suite?
Thanks.
Hi,
My gx2 was running cm10 and everything was working fine up until recently when my lcd screen broke.
So I ordered a new one and replaced the broken one, the repair has gone well , also the screen was good. Except there was a problem with the proximity sensor, when i tried to make a call the screen would go black and not switch on again, the only thing I could do was to take out the battery.
So I thought maybe I damaged the proximity sensor somehow while replacing the screen, so I bought a new sensor. The same Problem.
So I thought maybe it was firmware related even though I did not change the firmware and before the screen broke everything was working fine.
I flashed a stock rom, again everything went well , phone was working except the same problem with the proximity sensor.
Anyone know what that could be? Could I have damaged the motherboard somehow, even if that is unlikely because I was always extra careful and patient.

1. You should check if the sensor is really damaged. You can use e.g. Android Sensors app from Play store.
2. If it is broken, then try to disable it in ROM settings. I think there is at least an option in phone/dialer settings.
Maybe that can help.
Good luck !

I know how to disable the sensor, when I disable it calling works, but I want the sensor working . The thing is I thought I damaged it while replacing the screen, so I bought a new sensor, but the problem is still there.
android sensor box shows me a value of 0,0
typing in *#0*# and then "sensors" : the screen is always green an the phone is vibrating PROXIMITY: 13
the phonetester app shows Proximity sensor :near
I just figured something out.
The proximity sensor works when I hold the phone against a light source, when i do the *#0*# test and hold it against the light, the screen turns to white and the sensor works as it should( when i hold my hand near it, screen switches green and phone vibrates) , but only as long as it is near the light source.
Could the sensor just not be calibrated correctly? Is there a way to calibrate it?
than you
FYI, I just chatted with our Verizon corporate tech support and got this response when detailing my proximity sensor problems:
"There is a known issue with the Proximity sensor on that device.. LG is going to release a software update next month to fix it
I am just trying to confirm if it is for the same issue that you are having.. thanks for your patience"
Couldn't find a reference to this elsewhere, sorry if it's a double.
My problem is different as nothing will get it to stop reading "0ft" and the phone is pretty much a disaster at this point across multiple ROMs and resets. I'm having mine returned.
So what is the problem? I haven't experienced any issues that i know of with the proximity sensor
My guess is it'll fix the fact where if you're blocking the sensor, the phone won't turn on.

Isn't it a common feature of phones to do just that so they dont accidentally turn on in your pocket, hence the proximity turning it off.
Hi Everyone
Clarify me about something that is atrophying my mind. Does the proximity sensor exist on this equipment? What I want to say is this: when I am reading something on my cell phone, and when I'm not having any interaction with my cell phone (because I'm just reading), and how I have configured the settings to turn off the screen in 15 seconds. My question here is ... just because I'm in front of the mobile phone or just waving to the screen does not turn off (something I did in my Moto X 2014) why does it turn off? Should not it stay on because of the proximity sensor? I was using ROM Lineage 15.1 and I thought there was something wrong with this ROM in the proximity sensor, but I went back to the ROM stock and I noticed that I still have this problem. I was thinking that either this phone has no proximity sensor or it is simply broken. I bought this cell phone a week ago. Please help me solve this issue of the sensor.
Thank you
Regards :good:
