[Q] Proximity sensor calibration

Hey,
is there any way to calibrate the proximity sensor one the One X?
For some reason my proximity Sensor needs very high brightness values to activate the screen again, when calling. This happens on every ROM I use, even stock. Does anyone else have this issue and is there a solution? I've been looking for a while now but only found solutions for other devices. Help would be very appreciated

Are you taking about ambient light sensor?
Proximity sensor is sensor made for distance detection.

No I actually mean the proximity sensor. I know it shouldn't be depending on light but it does. I don't know why. First I thought the sensor is broken, but if there is enough light it reacts to movement. If not I'm not able to get the screen back on until the other person hangs up. Its really weird. Sometimes even the little red light stays on. In the DHD forum i saw a thread about someone who developed an app to recalibrate the proximity sensor, so i thought this could also be done for the HOX.

For your knowledge, the proximity sensor on One X is kind of binary type (return 0/1;object detected /none). There are some sensors test tool offers on play store, you may try them out..

Ok. I did that already. Same happens there. Thats why Im not sure if its malfunctioning or just needs to be calibrated.

Well, this is enough. I have to assume that its a hardware defect and I wont send it in a 6th time.Getting rid of this contract next week.

i had exactly the same problem. You can fix it with http://forum.xda-developers.com/showthread.php?t=1882725 this patch. All you need is a custom rom with init.d support. Cheers!

You can use this.

proximity sensor always on

Hi guys m facing a strange issue. I have observed that sometimes my proximity sensor remains on. I tried to find out the app causing it by Force Stopping each app one by one but that doesn't solve the problem. .
I am not using any motion like quick glance which uses the sensor or any other app like turning the screen on off (eg smart cover etc)
only a reboot fixes this issue but after sometime (say few hours or 1-2 days) the sensor turns on. . Can you suggest me what else shall I do? coz m observing more than normal battery drain in stand by mode. . Please help!

Try turning off "quick glance" under settings--> motion.

me too same here dagnamit

I too have noticed it and posted it on a thread also
I also notice this..only now i came to know that it is proximity sensor..will appear as a dim red right and if it stays on, it turns off only if restarted..might be a bug..should we report it to samsung so that they will fix it in updates?

I have noticed one thing that after 2+ or more (random) days of usage if I receive/make a call the sensor doesn't turn off. .might be this is a s/w bug. .but this is what I have noticed after closely monitoring my phone. .

I've noticed this too! Didn't know the dim red light was proximity sensor. But i've noticed it only twice (with battery below 40% on both occasions).

Viber has a known bug that cause the proximity sensor to be always on. If you uses it, u need to update to the latest version i think its v2.2.3.109.

Even though I first got this proximity sensor bug after I turned on "increase volume in pocket" (only 1 time so far), I'm pretty sure it's not related, because I did a few tests and as far as I could tell the phone increases the volume based on its position (and possibly movement) in the second it receives the call. If it's vertical (like in a pocket), or on its side (like in a bag), when you get a call, it will increase the volume. If the phone is horizontal, like on a table, and starts ringing, the volume doesn't increase, and it won't increase even if you pick it up and move it around while it's ringing.
I also thought initially that it uses data from the proximity sensor, but I tested and it doesn't care if it's covered or not when the phone rings, it appears to use data from the accelerometer/gyro exclusively.

I'm try turn all motion off right now. Let see if it can solve the problem

I have the same problem.
I resolve it by pressing volume up + home + power.
Let it restart and so far after about 1mth+ did not encounter this issue any more.
Hope this help :fingers-crossed:

i have the same problem
all motions are off
and still have it random....only restart to close the sensor

[Q] Samsung Galaxy Note 2 Motion Sensor and Gyroscope not working

hi i just recently bought a galaxy note 2 phablet, im very happy with it every thing works perfectly fine, however i did come across a slight problem which is bugging me alot, as i loaded the phone up it shows you all the tutorials and stuff, for panning and zooming in using motion control.... i did not realise the problem before as i was really happy to just get the phone after so long, My motion sensor and gyroscope functions are not working
i have tried everything from factory reset to restarting , taking the battery out and putting it back in, has anyone stumbled upon this problem, and is there a solution to this problem, whether this is a software glitch/problem or a hardware issue. if anyone can help me please and thanks in advance

hi thank you for the quick reply, i had a look at what you asked me to do and i did manage to find all the settings, however it looks to me everything is working apart from the light sensor one, all the other settings came up as a PASS apart from the light sensor which came as level 0, which i dont know what that means, while i was on the sensor screen i swiped my hand across the sensor and the screen shifted colour from white to yellow, which is a good indication that it is working , however i went back on the operating system and tried the palm swipe and it did not work, niether did the quick glance, and the pan to zoom features are not working either, i did test the gyrocope settings and it came out as a PASS too, could you explain maybe why this may be happening and what does the level 0 on the light sensor option means, please and thank you , i really do appreciate it.

Lavel 0 says to all phones I have tried including mine. As long as the LUX changes it is working.
Now for your primary problem try to recalibrate gyroscope.
Do it by going settings-motion-advanced settings-gyroscope calibration.
If that does not help try clearing cache in recovery.
If that does not help then backup and try reflashing your rom.

Hello in response to your issues with the motion sensor. Have you installed a screen protector on your note 2? i noticed that after installing the screen protector on my Note 2 some of the motion actions did not work properly. So if you do have one on remove it and see if that corrects the issue. :good:

Useful help.
This was a very Useful thread, thanks. I've done the tests and came up vitha a fail when i tried my motion sensor. Is it likely to be broken? I'm going to reset to factory settings and pull of my screenprotector and se what happens before i do anything else. Is there anyone out there who has replaced the motion sensor? Is it soldered to the main board? Hard to replace?
Thanks beforehand. Tommie.

i thnk my sensor is nt wrkin... when i do the test, d color is alredy green nd isnt changin nd is vibratin continuosly?? is it broken or somthng lyk dat??

Samsung Galaxy Note 2 Motion Sensor and Gyroscope not working
hi my samsung note 2 was working well for last 2 years bur recenrtly its motion sensor has stopped working.
i have checked all settings, it isnt working at all..
gyroscope and motionsensor tests are fail on checking. please help me, what to do?

I have had the exact same issue. The only way to fix it is to get the whole motherboard replaced. I went into Samsung store and they said that. Issue here is that it costs £145 to replace the main board. The sensors are on the main board itself and that is why it costs a lot to fix. I've been using my Note 2 with no gyroscope for a few months now, going to buy a new phone. Rather buy a brand new phone than get it fixed

just loosen the screw nearest to the microsd card. motion sensor is under it. it work on my phone.

Hi,

Yeahhh!!!
You are a Hero! I tried nearly everythink since January 2016! I took the screw out, shut down my phone, put it into download mode and pull the battery out.
Im not shure if a restart would do it alone, i did all to be shure. And it now works again. My srew was magnetized! Maybe that was the reason or the chip has
a loosen contact.
Up to now it works great! I thought my sensor was dead.

Huge heat when in pocket

Today I kept my OP3 (Stock Rom Rooted) for 10/15 minutes the phone in my pocket and it become extremely warm (seems to be nabk with my OP2) !!
I made the following thoughts:
- the ambient display wakes up the phone and make it warm
- the FPS feels "something" and it wakes up the phone
- the proximity sensor doesn't work properly
Does some of you ahve the same issue ? Any feedback is welcome !
Now I disabled the ambient display, and let's see what happens.

I am facing same Heat issue when in pocket and riding the vehicle. Have disabled Gesture control in phone setting, Let us see the result.

yes..me too facing the same heat issue

Same here

I didn't used your thread just because you talk about energy and not heat (even if usually mr Joule said these are linked)... BTW I read it's because of fps: could be... I want to try the setup without gestures and ambient and than I will confirm it!

Hey!
it also generate heat here...
It's definitely the fingerprint sensor. Face the screen outwards inside your pocket and the problem doesn't occur anymore (thanks @Rauttis)

This happens to me also but I have no gestures enabled on the lock screen so it can't be that. Thus as MagDag says, it is probably the fingerprint scanner. I'll try to face it outwards to prove it.

It's not due to gestures. As I said above, I have gestures turned off (and ambient display off too) but this problem still occurs for me, frequently.

Hi, yes, I think it is due to the fingerprint sensor. I must have placed the phone facing away from my skin after disabling gestures (which was pretty stupid).

Lol. Proximity sensor.. Whenever that's blinking, put your hand over the phone, the screen should go off. Like when you on a call.

You can set around notch only.

That is the proximity sensor, see that it activates when you play your voice note on whatsapp, if you call you will also see it. Notification led apparently will be the ring around the front camera, sane way as it activates when you switch from back camera to front
