Note 8 sensors not working - Samsung Galaxy Note 8 Questions and Answers

Hello there!
Well just like the title says, I have a Note 8, wich is almost like brand new, not even one drop to the ground, not a single scratch, and also no funny apps, just the basics for everyday.
Thing is out of nowhere, several sensors stopped working, no matter what (factory reset, hard reset, wipe cache, safe mode).
Fingerprint scanner: WORKS
Proximity sensor: DOESNT (calls never turn screen off)
Iris scanner: DOESNT
Auto bright: DOESNT
Auto rotate: DOESNT
Heart rate: turns on, but doesnt register your pulse
I've read a lot of people having this issue, some say it was right after a security patch OTA, other it's a faulty batch of motherboards, yet no definitive answer.
Do anyone knows if this can be fixed? It can't be a hardware problem since its like brand new, unless the update somehow fried something inside...
Hope I was clear enough about this, any ideas you have could help!
Thanks!

Did you perform HW test, USSD code *#0*# in phone dialer?
May be useful to report your phone model (Exynos - N950F or Snapdragon-N950U or other)

Yes I did. Everything is stuck at 0.
Oddly, today I tried the heart monitor again, and it registered almost 50%, and then says finger is not where it should be, not reading anymore...

Problem with the Front Facing camera.

I was wondering if anyone else had this issue with the front facing camera. There's a couple people that had this issue as well, check the
mentions for SamsungSupport on Twitter a couple days back(at the time of this post)
There's even a video of it in action: https://twitter.com/Hired_Assassin5/status/918633351510200320
As you can see at the top, there's some major discoloration going on. It's almost like a negative image.
https://i.imgur.com/2ipVzgS.jpg
I got the phone on Sep 15th, release day. The camera was working fine up until around Oct 5th that I know of. Taking selfies with the dog, etc.
Well, I opened it up on the 12th, haven't used it for a while, and I noticed that issue you see in the first image. I contacted Samsung and they had me
go through the whole troubleshooting process, all the way to me factory resetting my device. Factory Reset, then skipped all the setup wizards
and went straight to testing the camera. Issue is still present!
So the next day, I went to my carrier store, they said they never seen that before. So they're ordering me a shipment to replace it, possible defect.
Well, that night, I decided to try and look deeper into the issue. Flashlight on camera lenses, didn't see anything. Then I remembered from previous
android phones, there's hardware codes you can enter into the Dialer, so I input *#0*#, which is the hardware testing screen.
It looks like this:
https://i.imgur.com/RhJD4WJ.jpg
So obviously, one of the options is "FRONT CAM". I thought I would "test" it. I clicked on it, and it was working fine! I said oh sh!t, WTH.
This is the screenshot of it:
https://i.imgur.com/2BiaA7U.jpg
Then I took the picture as well, and it turned out just fine, like a normal camera. Well when you tap the screen again, it backs out, and switches
into a different mode, or something. And well sure enough, that issue I was having in my main camera app showed up!
This is a screenshot of it:
https://i.imgur.com/kGgJDD1.jpg
Now this is where I'm wondering if the Geniuses and good people here at XDA can figure out.
If you notice in the first screenshot of the "test" https://i.imgur.com/2BiaA7U.jpg
It says SUB AP at the top left....
Then in the next one, the defective one or whatever https://i.imgur.com/kGgJDD1.jpg
It says SUB CC.
Does anyone know what those are, or what they stand for? And if possible, how can I get my camera app to go back to using the correct mode or whatever that is.
This issue happens in all camera apps, the Samsung default camera app, play store camera apps, etc.
Thanks.

I'm not having that issue *knocks on wood*
But it doesn't sound like a hardware issue though.
Sub AP, Sub CC are probably different Samsung settings not available to end users. Any advice I'd give is to back up, hard reset, test if problem still present, if problem fixed restore data.
When does the problem usually happen, in bright or low light?
What if you use the front camera "flash" does it still happen?

I originally thought it was a hardware issue, but seeing it function normally when I did the diagnostic testing, I knew it had to be
something that triggered the software to not work correctly.
the issue is still present no matter what settings I change. Changing resolution, flash on/off, picture size, HDR on/off/auto, all the settings
I can find, the issue is still exists.
EDIT: Is a hard rest the same as a Factory Reset?

Dam, that's unfortunate. That's 4 people now that have had this issue. I wonder how much worse it will get. Hopefully the new replacement doesn't have this issue.
It's weird because it was working fine for a few weeks, and then something happened. Not sure if it auto updated without me knowing and caused this issue.

sounds like they're sending you a replacement. make sure you are satisfied with the replacement because they might send you a refurb.

Nope, Samsung never got back to me. I just went to the Tmobile store and they were like, yep, never seen that before. So they overnight me a new one.
I just begun to have the same issue on my phone and I'm not happy after spending 1k on it. I'm going to my career tomorrow but unfortunately don't know I this will be resolved. Please Let me know what Samsung did for you.

If you did not mistreat the device, dropped it or fiddle with system settings or something of the sort, warranty is the all time solution for these problems
Hey my note 8 front camera just experienced the same issue. I've talked to Samsung support, and frankly it seems like it is a hardware issue. It is recommended that you use Samsung Support to make a service request. Free shipping both ways, so if you can live without your phone for a week or two (or have a backup phone to use), that's the route I recommend people going.
Original Problem:
MENU / COMMON APPLICATION ( NATIVE) - CAMERA / VIDEO - CAMERA EFFECTS NOT WORKING
Problem found:
FRONT CAMERA FAIL
Solution:
REPLACED COMPONENT

My front selfie camera has the same problem!
sorry to raise up this issue again.. my s8+ is from Indonesia region, and facing the same issue when try to use front camera is failed with notification Warning Unknown Error Occured.
already try Wipe cache partition and hard reset but still facing the same issue..
but if i use front camera for video call thru whatsapp it's working fine, but yet again if check thru *#0*# for Front Camera it's Camera Failed..
is it hardware issue or FW issue ?
Front Facing camera has double image
Has anyone found a fix for this issue yet? Mine started this issue last year and I haven't found a remedy for it yet. Ugh.

Note 8 "The Iris Sensor not responding...": HELP

My Note 8 cannot use Iris scanning any more. I got the message "The Iris Sensor not responding..."
My question is "is it HARDWARE related or Software problem"
Because if it is hardware issue, I should prepare myself to see if I can do the exchange.
Thanks

Things to try to rule out software. First just restart the device. Check. Still broken? Shut down device, boot to recovery and wipe cache and then restart. If it still doesn't work try a factory reset. If a factory reset doesn't clear the problem then I would exchange. I personally would exchange regardless. That isn't expected behavior IMO. I would assume the device itself is faulty. Even if a factory reset corrects it, what's to say it won't happen again.

Impossible to diagnose without more info.
I have the same issue, none of the sensors work, i mean proximity, gps, auto brightness, and gyroscope don't work on my Galaxy note 8.
Does anybody know what should i do?
I also rebooted my phone.
When i am on Google maps, and turn the location sensor on, suddenly the phone finds the location, after that, the sensors doesn't recognize the location.
it also happens for auto brightness sensor, when i unlock the phone, it works, suddenly it stops working and doesn't change.
I tried *#0*# none of the sensors values are changing.
I don't know what the problem is? Is it about the software or the hardware?
I updated the phone, did factory reset, wiped all the data, but nothing's happened.

Yes it sounds like hardware. As long as your phone had been damaged or we you should be covered under warranty

Hi, did anyone figure the problem out? Bought mine 10 days ago only. Thank you. hardware or software?
If you have not been tinkering with the phone by means of flashing things, rooting, etc, then it is hardware related, go claim warranty ASAP!
Thank you. I'll look for the guarantee tomorrow!

Samsung galaxy note 8 sensors not working

Hello,
My Galaxy Note 8 GT-N950F sensors are not working. Proximity, heart rate, barometer, rotation, iris scanner and other sensors are not working.
Any HELP please !
Happened today, i saw some people got same issues since the new Android 8.0 updates.
ANYONE HELP ME PLEASE!!!
Did you check sensors from test menu:
*#0*# (in phone/dialer)?
Yes already dialed. Nothing is working. Download CPU-Z too, nothing is working. Hard reset too. Same issues.
Any other solution?

Same thing happened to a friend on 7.1.1 with a 950F.
He had to claim warranty on it since we tried multiple firmware's, but nothing brought the sensors back.

Chances are you won't get your exact phone back. But a refurbed one. Just use samsung backup app. Works pretty well. And of course factory reset afterwards.
I'm having the same issue with my device past few days (Exynos Chip)

I haven't experienced it myself, but previous posts in the thread indicate a hardware problem... If you already flashed the latest stock firmware with full wipe and it's still not working, then it seems to confirm that hardware issue.

Can you find those posts you mentioned and link them here? If it's software related then flashing the latest stock firmware should help. Did you do a full wipe and used csc instead of home_csc in Odin (along with the other firmware files)?

As some buddies stated before, take your device to claim warranty, that's it
I'm getting GPS errors lately, very very weak satellite signals even under 100% sky, I don't know if they are related. Ugh, so much for a $1000 phone
Echoing the responses of others. I would take your device to either the retailer or a Samsung Service Center. As this is probably a motherboard issue.
Facing same issue, all sensors not working. Will be going to care center tomorrow.
I had this problem after I had my phone led screen repaired (under warranty at samsung). Lucky I check everything after every repair.
They took the phone back and got it fixed in 5 minutes. Said the tech forgot to flash in some files.no idea what files but all they did was change the screen and battery.

Many problems with my Mi9

Hi I bought a Xiaomi Mi9 not even a month ago.
These days I found a really annoying problem, my Mi9 unlocks itself in my pocket. I state that I have done all the possible tests, that is with and without double tap, with and without unlocking via mi band4, with and without lifting option, password, fingerprint and face detection. Trying various combos (thinking that maybe some of them would conflict with each other) I arrive at the same conclusion. Start the emergency keypad on your own, or if I receive notifications it even opens me up or I find myself navigating through my apps.
This is the main problem.
I have found other problem, like if I talk at the phone, I put the auricle in the right ear, everything is ok, while if I move it in the left ear I no longer feel anything. (proximity sensor
defective ultrasonic?)
Another problem that perhaps seems to have solved was that of bluetooth devices, the saved devices menu was missing. With a reset I fixed the problem at the time.
The fingerprint detector every 10 attempts, 3-4 never go through if the screen is in total standby, while if you wake up the screen in any way and then use the fingerprint it always works.
The most important thing I would like to solve is that of unlocking in my pocket, it particularly bothers me. I read that in June they had to fix this option, optimize it, but apparently it doesn't seem improved. I know that here the pocket mode is automatically inserted compared to other devices. But apparently it doesn't work at all.
I have the device correctly updated.
Help me discover something more or at least solve this problem and sorry for my bad english i'm italian boy =P

Hi
Which firmware, rooted or unrooted?
I can recommend to root and use firmware of xiaomi.eu
If you have the latest firmware with pocket mode included your only two options to fix the pocket unlocking’s are: 1. Get at flip cover. 2. Delete all fingerprints and use another unlock option like face recognition or so. This will also get you noticeably better battery hours.
The speaker problem I think is a problem with the position. It is very critical that you put the tiny speaker hole exactly in front of your ear opening, a couple of millimetres aside will make the sound almost silent. This is if you by feel mean hear. Try to hold the phone at an angle out from you face with the upper part pointing to your ear and move the phone up and down to se if you can hear better.

This is the main problem.
I have found other problem, like if I talk at the phone, I put the auricle in the right ear, everything is ok, while if I move it in the left ear I no longer feel anything. (proximity sensor
defective ultrasonic?)
Another problem that perhaps seems to have solved was that of bluetooth devices, the saved devices menu was missing. With a reset I fixed the problem at the time.
The fingerprint detector every 10 attempts, 3-4 never go through if the screen is in total standby, while if you wake up the screen in any way and then use the fingerprint it always works.
The most important thing I would like to solve is that of unlocking in my pocket, it particularly bothers me. I read that in June they had to fix this option, optimize it, but apparently it doesn't seem improved. I know that here the pocket mode is automatically inserted compared to other devices. But apparently it doesn't work at all.
I have the device correctly updated.
Help me discover something more or at least solve this problem and sorry for my bad english i'm italian boy =P

Let me suggest a fix for the fingerprint issue.
Turn off the show "fingerprint on lockscreen option"
There really isn't a pocket mode for the mi9 because of the in-display fingerprint reader
About the "unlocking in your pocket" issue, I think you should try a different unlocked method, maybe a password to see if it's still there, and also ensure you don't have "On body detection" enabled in settings.
where did you buy it?

All (almost) sensors stop working

Hi everyone,
Almost all sensors stoped working after few days on my brand new Pixel 5 :
Failing sensors :
- Proximity sensor
- Accelerometer
- Gyroscope
- Compas
And maybe others I don't know of...
Fingerprint & cameras are still working.
I've contacted Google support, and they advise me to clean my screen :-/
I'll try a factory reset today before asking for a replacement unit, but my hope is low...
Anyone facing the same issue ?
Any advise ?
Edit :
After a factory reset : same situation
Same here. Had phone for about ten days. All seemed to work. Then thinks went weird over several days. First thing I noticed when going to hang up a call I was no longer presented with phone dialler screen. During calls phone was also spontaneously switching to handsfree. I suspect this was wall tilt related. Then camera images were in incorrect orientation. Google photos not longer rotating images and so on. Installed a sensor app and it reported gyroscope as missing. Clean booted - no change. Factory Reset and still no change. Arranged for an exchange with Google. While waiting for that to pan out, after about a day the gyroscope has come back to life. Although presently reporting no compass. Doe the P5 have a compass?
Anyhow given it working again now I am wondering if some power saving activity is killing the Gyroscope? Waht was the out come with your sensor failure. Did they recover or did you need to exchange?

I tried a random app from the store : Sensor Test with my bad unit and it reported 0 sensor !
I've exchanged my P5 and now the same app reports 30 sensors.
While waiting for the exchange , mine never came back to life : can't rotate, screen stayed on during calls (and auto brightness not working), compass was not working in Maps...
Also on the faulty unit I noticed that the OTA update tooks ages (30 minutes or so, for a ~30MB update). On the new unit, the same uptate took just a normal reboot time.
Thankyou for the update.
While mine has a working gyroscope (at the moment) the proximity sensor is still borked and the screen stays on during calls. I just installed the Sensor Test app and it says I have 16 sensors!
30 for me

30 sensors also for me.
Oh my god yes exactly this happened to my phone since yesterday. No auto rotation, no auto brightness, no tap2wake.
I have to send mine back, I hate it. Sensor app does not recognize a single sensor. Factory reset didn't help either
When rebooting like 10 times it changes between 0, 1 and 16 sensors.
I factory reset my phone again and that made it worse. Has gone from 16 to 0 on Sensors Test!
Has lost screen rotation again.

At this point, you should contact Google Support and ask for an exchange.
Like my old one, I doubt this is a software issue...
I hope my new one does not have this flaw.... but this definitely hurt my confidence in P5 devices....
Sounds like issue with corrupt persist partition caused by update gone wrong.

Indeed ! I didn't know about this.
But it seems that the solution is to root the device, and this void the warranty (Google asked me if it was rooted before the exchange).
Weird. It did not happen to mine right after an update, more like 20 days later. Btw Google did not ask me if I rooted the device, which I haven't, but I did unlock the Bootloader for a short period of time to use the android flash tool from Google.
I'm not very familiar with partitions on android but all I can say is that a newly flashed stock firmware from Google itself did not help me
All my sensors work according to that app - it shows 30 sensors every time I launch it - except the proximity sensor sometimes does not actually work right. I was noticing an issue because KinScreen would think my proximity sensor was covered and would turn the screen off because the proximity sensor looked to be covered when it was not, even though the app should have kept the screen on. I downloaded multiple sensor testing apps and the proximity sensor works most of the time but sometimes it does not. Weird. Not sure if I should exchange the phone, I got this with AT&T.

Took a couple of weeks, but I now have a replacement unit. 30 sensors showing and all working properly now. I took it for granted how reliant these devices are on having sensors working for basic things like the phone to work properly. Glad I found this thread and was able to get it sorted out. thanks for the help.
I had to get a replacement PIxel 5 through AT&T for the broken proximity sensor. This one works fine.
Couple of weeks?
I got a new device within 4 days where 3 days were for shipping
Just out of curiosity, am I the only one Google asked if I have rooted my device before sending it back ?
They asked me 5 questions for the warranty (I live in France/EU btw):
- Has the device been impacted, or is the screen damaged?
- Has the device come into contact with liquid?
- Has the device been in contact with a heat source?
- Has the device been rooted?
- Has the device been repaired by unauthorized personnel?

I started an RMA process on their website and no I'm not 100% sure about the other stuff but I'm sure they didn't ask if I was rooted.
Germany
I see where Google announced that a fix in the December update could possibly fix the sensor issue for some. I'm guessing you guys got the update and it didn't work huh.
idk I got a new device in december
