[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.

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.

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.

ogp sensors problems

Hello.
I bought my ogp a week ago and i discovered a problem with the motion sensor and the proximity sensor - both dosent work.
Some one know how to fix it? The seller said it's a software problem and an update will solve it.
Thanks.

Is your phone rooted by chance? There's a program I use called kernel tuner and it has live statistics of all the sensors.

Do you have a screen protector on that covers where the sensors are by chance?

No, my phone is not rooted, i checked the sensors with another app and all my sensors are turned off, no one is working and replying data.
About the screen protector it dosent cover the sensors so it is not the problem...
More ideas?
Thanks!

Did you try to check for software updates in the About phone section of the settings application? If there's an update there's a chance that that could fix it.

Light Flow issue

Hi guys, i'm having some troubles with Light Flow and KitKat on my Nexus 4.
I have set the led notification color etc.. but when there are notifications the led doesn't pulse.
I also try the testing mode of any notification and the led doesn't pulse but the led works..
Someone else has this problem? solutions?

I dont have any issue on my nexus...and you're wrong forum section..it should be on QA and Answer..

Same thing happens on my N4 with the paid version on stock rooted KitKat. I did a LED test in Light Flow to make sure everything works and it does, but the LED lights up about 20-30 seconds after I begin the test.
I then tried the free version of LEDBlinker and the LED lights instantly during the LED test and actual notifications.

No problem, at all.
Light flow works like a charm to me.
Stock, rooted, clean install of 4.4.

I have a problem on KitKat it notifies me but sometime a notification isn't dismissed from the app so the led just keeps flashing. Its annoying but as KitKat is new it'll hopefully be fixed.

I have a issue with lightflow too .. sometime the led is working like a charm, then sometime (like 20% of time when i got a notification) nothing happen, i mean there is no led notification AT ALL !
Didn't try LEDBlinker because i like light flow for its feature to open screen for 5 second when a notification income

I have the issue where if I want read a text message after my screen is turned off then the light blink continues to go off. Its really annoying

I had also wait a bit to see if the led was pulsing, but now it doesn't works..
I couldn't find anything on internet so I thought it was only a my problem..

Make sure to turn the accessibility service on and tick the notification access. (Security->Notification Access.)
Works perfectly fine for me, haven't had any issues with Lightflow on KK.

Try using Light Flow in "Foreground Mode" (No idea what the setting is called in English - i'm using localization), it sometimes gets killed by Android to free up ressources for other apps.

There's a new update out that has a few fixes for Kit Kat. The long delay of LED notification was fixed on my phone and all my custom settings react instantly.

With the new update, my hangout sms led never work now .. before it worked sometime and sometime not, but now, it doesn't work at all .. i'm very disapointed ..

The same happened to me, I found a temporary fix for that specific issue, though. If you go into the Lightflow there should be an option called like "Hangouts - All Notifications" or something like that, enable that one and the LED should start working again when you get an SMS in Hangouts.

The update isn't perfect... Sometimes it fails in SMS, but i think it will b just fine in the next couple updates, it's a very good app.

Maybe there is dust...try to open phone i clean it from inside

Are you on 4.4? Did you did a fresh and clean update or simply updated 4.3 to 4.4? There are some people experiencing issues when they just updated..

Flashlight not working

hi,
on the quick settings, there is a flashlight button,
but when i click on it the button becomes activated, but flashlight doesnt turn on
i first though that the flashlight was broken, so took a picture, and flashlight worked
then i installed a flashlight app, with that app flashlight is also working
then i tested again from the quick panel, and it was working
now, after some hours, flashlight from the quick panel is not working again, only the from the app/camera
thnx

am i the only one with this issue?

Have you matched your firmware and rom, either to MMB29K or MMB29P? My suggestion is to use fastboot to make sure everything is matching, so flash at least boot.img, system.img and vendor.img if you are on stock rom. Then try it again.

hi, i am on MMB29K
i ame not rooted or unlocked or anything like that, just everything stock

Oh, then fastboot is not an option. Hmm, have you tried clearing data for the camera? This is the first I've heard of a 5X flashlight issue on stock.
Sent from my Nexus 5X using Tapatalk

that doenst help, clearing data
when i open camera, and enable flashlight, then the flashlight from the "quick settings" is working
i reboot the device, not working anymore
also when enabling it from the quick settings, the flashicon doesnt turn on white , like other quick short settings

I am not sure why that would be the case. Do you know when this first started occurring? Do you have an overlay on your phone? Something to decrease the screen brightness or that applies itself over your screen, like a constant floating notification.
Sent from my Nexus 5X using Tapatalk

No overlay or anything like that, but i maybe found the bug, i think it has todo with battery/doze mode... When camera app goes to sleep mode, it doesnt work... Added camera app now to whitelist of battery optimazation, lets see what happens now...

ignore last post, that didnt help either
