[Q] Dead Sensors - T-Mobile Samsung Galaxy Note 3

Hi there everyone,
I've been a long time reader but first time poster hehe
I just got a slightly used Note 3 (build N900TUVUBMI7) and upon checking that everything was working properly I noticed some issues with the sensors, so I checked by dialing *#0*# and this is what I got on the Sensor tab: (you can see it in the attached picture) All the values are at ZERO!
I know chances are I just got broken hardware, but if that's not the case, are there are software solutions I could try to restore Sensor functionality?
Thanks.

Did you put your hand over the sensor to see if the value change?

I just checked one out, that had the same problem. In that case, the previous owner had replaced the screen and damaged the front camera with the sensors. Camera is very easy to replace and cheap. But he'd also broken off two contacts on the motherboard, which must have had a role in the sensor control. Got the camera working again, but not the sensors. If you can't return the phone, it might be worth buying a replacement front camera with sensors, but maybe open it up first, and see if anything is loose or disconnected.

[Q] Proximity sensor problem(?)- can flashing a ROM solve it?

Hi,
I've searched high and wide for a solution (other than sending it back to Motofailure repair) and am failing at finding one so far. So I'm hoping I can get some help from here.
So, this is the situation: I make a call, screen instantly turns dark and will only light up again when I press on the area where the light (&) proximity sensor is.
I've already tried the following.
1.) Done a factory reset (3x) - with mem card, with reformatted mem card, w/o mem card.
2.) Clearing the dust on the earpiece hole using an air duster.
3.) There were times that I worked properly after I've uninstalled apps but the issue came about again after a couple of tries.
So, now I'm thinking that I might want to root my Defy to set things right. I'm quite familiar with RSD Lite as I've used it before on my RAZR2 V8.
A bit of background: I bought my Defy on pre-order so this is one of the earlier models. I had the earpiece problem and sent it to Motofailure repair and the whole process took a month (32 days to be exact - long story. I'm avoiding having to send this PoS back. They updated the software when I got it back.
As far as I can recall, I didn't had this problem before the earpiece problem. And I'm thinking it might be a software problem hence I'm now looking at a solution by rooting and flashing the ROM with an original one.
I have no way of finding out (as far as I know) whether this is a hardware problem (hence hesitating to have it sent back to Motofailure repair).
What I've also observed is that when there is direct bright light, it works normally but when its dim, then the problem appears.
I don't have any screen protectors, just so you know.
Can anyone advise me on what to do?
During a call proximity sensor is activated to turn off the screen at the moment it detects proximity and asumes you are using the phone against your hear, so it turns off screen to save energy.
I think you might have some app installed in your phone, using and reversing the sensor status so it detects proximity when there isnt, and viceversa
You might want to try removing apps using that sensor and see if problem gets solved, there is also an app in the masket called sanity; which makes extensive use of proximity sensor for vaqrious things, and have an option to reverse proximity sensor, you might want to try it and see if problem gets fixed.
You might try this things: remove apps using proximity sensor, test phone. Deactivate in pocket detection; test phone, and install sainity, test phone, install a new rom?
If speaker is bigger than original one, or there was an assembly error, light/proximity sensor won't fit into right place.
I've seen such reports and you can't do anything unless you open up thing and check the problem, but you haven't seen the right assembly so you may not know the right place.
Are you using any screen protector? I know some screen protectors cause this problem.
Edit: Nevermind, I see that you're not using any.
how to calibrate the proximity sensor?
My new defy 's proximity sensor seems cannot work correctly,when i making a call ,the screen shut off immediately,and the screen could not light on by any key,but when i touch the proximity sensor with my finger,the screen may be light on!
so i download a app to test the proximity sensor which name's"Android sensor data",this app fingue out the state of proximity sensor,"near" or "far",sometimes I just passing my finger over the proximity sensor, the reading will show 'near' and then remain 'near' even when my finger is moved away!
Can anyone else help me to calibrate the proximity sensor?google told me some android phone can do this ,such as htc, zte etc.
goole tell me android phone have some standard testcode,such as *#*#4636#*#* can show the phone statue,it works correstly in Defy,*#*#0588#*#* test the proximity sensor ,but it doesn't work in defy!!!
I don't think this issue could be solved trough software tweaks. Chances are this is a hardware problem. Maybe you should contact the Motorola support.
try disabling in-pocket detection
have the same problem. it started 2 days ago. Im using CM7. It just turns dark and wont wake up unless someone else is calling me. Just got it tested, and when i cover the sensor with my finger it says 0cm distance for long time.
I've tried data wipe and similar, but nothing helped so far.
EDIT: I've just tried wiping the place where proximity sensor is with some soft cloth and alcohol and for the time being, it works. O.O
Could Wipe Dalvik help?

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

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.

Desire HD Proximity Sensor Replacement

Hi all i have a DHD with a screwed failed Proximity sensor and was wondering if it can be replaced.
I have looked at all the videos of tear downs, done the calibration the works and Sensor doesn't work at all not even it its factory stock rom.
So how does one go about replacing that part if its possible.
I very much doubt it will be as simple as replacing the casing.
Please help.

I have the exact same problem, phone has been flawless for 2+ years. Was away on holiday recently and used the night clock mode, power attached with the phone in landscape mode - following morning, no more rotation, calibration tool doesn't register anything, other market proximity tools show a sensor present but don't function.
Cleaned the sensor with a fine brush, no change, re-flashed a couple of roms with full factory reset, no change.
I can only assume the sensor has failed - shame this phone has been excellent - especially with the dedicated ROM community behind it.
I am now facing a full tear down next to try and clean the sensor fully, although suspect this will make no difference.
Can the proximity sensor be sourced as a part, or does anyone have any other suggestions/ things to try?
UPDATE: Following the guide on this thread fixed it for me!

Problem with Proximity sensor and Network Issue on note 2

Hello Guys,
I'm facing issue with my Samsung Galaxy Note II proximity sensor and Network Issue on it,
Network Part:- First of all it was working fine, after getting patch for KitKat 4.4.2 and installing network issue arise, like suddenly i'm not able to make call's or receive it or even unable to access 3G internet on it, it will show 2 tower on device and "H" symbol but no calls will be done or receive it, while network goes unavailable.
Proximity Sensor:- Proximity sensor is not working properly from last 15-20 days, I tried resetting device, blowing air on sensor on whole device, executed few application gyroscope explorer and few other, but issue still persist.
Today I came to know, when I press front camera part or near to it, then proximity sensor is working fine with out any for a while, then again I need to press it near front camera.
Thanks waiting for your solution's....
Did you managed to get a solution for that!

Appreciating your feedback.
It would be great if you explain a little how to install such part! And from where I can buy it.
Many thanks for your valued support.

Which board on the nexus 7 contains the gyroscope?

So, I recently installed Lineage OS on my n7 and noticed auto rotate wasn't working. Then flashed it back to stock thinking the lineage rom was bugged, still no auto rotate, it used to work last time I used the tablet around 3-4 months ago, so im wondering did the gyroscope get fried or something?
Anyway which board contains the gyroscope, the motherboard or daughterboard, anyone know? Recently replaced the daughterboard so im thinking that may control the gyroscope? I want to replace whichever board contains the gyroscope as it doesn't even show it moving in check my android app, don't really want to waste money on the wrong board if possible, so if anyone knows for certain it'd be a huge help!

The gyro is on the daughterboard but it never fails. Connection of the wide silver cable between the boards is the problem - see my earlier post https://forum.xda-developers.com/showpost.php?p=66952073&postcount=3

But then wouldn't the gyroscope show as moving in apps that can test it? It shows up as stuck, and on the twitch app it acts as if i am shaking the tablet cause it just keeps going from dark mode to light mode because twitch app has a feature that allows you to shake to enable dark mode/light mode.
Anyway I have tried re-seating the ribbon cable about 20 times now and still nothing shows up on gyroscope, even tried 2 different cables

The gyro and compass sensors share the same I2C data line connecting the two N7 PCBs. Please check with a sensor test app if the compass works - if yes, then the gyro has failed indeed.
Some apps will show you the sensors names - N7 has:
gyro Invensense MPU-6500
compass AKM AK8963
:good:

Hmm, the compass seems frozen as well I don't understand though the ribbon cable seems to be fine no matter how many times I disconnect / reconnect it nothing seems to change... Very odd
I have same issue, I use rotate app to manually rotate and also automatically rotate some apps. Eg auto rotate YouTube and media player to landscape.

With the silver ribbon cable connected at one end try and get it tightly moulded around the battery hold it there and connect the other end. I found this out recently after a battery swap it helps to push the connecters in a bit more those few microns matter. I was having screen rotation problems after a recent battery swap after doing this everything's perfect again.
