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.

Go to Samsung ASAP to get it fixed under warranty

I've claimed the warranty, still waiting for the phone
Will I lose all my stuff on the phone? Or will It be the same?

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)
My reply was here.

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.

But i saw some post saying that Samsung fixed there note 8 without opening the device and it also happened to me after software update to oreo maybe it is just software problem and also saw some post about xiaomi devices got this problem by software update.

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)?

i'm really sorry but can not link them because i saw so many websites and can't remember and yeah i flashed all files with odin but this also don't work any other solution and also saw a video on youtube about xiaomi device sensors stoped after software update

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.

No its not a hardware problem and samsung knows this only happening to the xynos versions and if all ur sensors were working fine how the fock after u update to their ****ty oreo update that they didnt take the time to do ur sensors stoped work its like when apple sent the update to the iphone 5s now the finger print sensors dont work.

Mi A2 Camera Focus Issue

Hello, my Mi A2 seems to have a strange effect when focusing on the primary lens. I would just like to know if this is normal or not. It seems when on the low light lens the focus is even across the image but the primary lens it seems to wash from one side to the other.
Here is a video to illustrate.
Does anybody else's do this? Thanks!

I've been having the same issue for a while now! It's very annoying and I have no idea how to fix it! I've been using the low light lens and just taking pictures with that. I cannot tell if it is a hardware or software issue either. I'm going to install a custom rom soon, just haven't had time to do it, so hopefully that fixes the issue!

i think it's a software issue, because after capture everything is OK

I still have issues after capture. If I'm capturing text the top half is unreadable in portrait because it's so blurry, and when I tap to focus on the top it doesn't help.

Same issues here
I have exactly the same issue... It seems like the extremes of the picture are better and the sides really blurry. For text is really bad, and also for pictures when you want the focus not being in the center. As you mention, touching the focus does not help.
I have no solution for now, thinking on sending it back...

Doubed HW issue
I'm sorry to say I feel it like a HW issue as I am facing the same issue with GCam in my MI A2.

i too have the same problame even after capture...

It's fixed on my phone now, unfortunately I had to get a new camera module. The issue is likely caused by a misaligned lens element, so the only option is to swap the camera module or warranty the phone. Mine works great now. Shouldn't have had to fix it but I guess these things happen I guess.

It should be pretty straightforward, here's a teardown video: https://youtu.be/mo92gAwKv6s. That should walk you through getting the module out.

Can you send a link to the module you got? There's several between eBay and AliExpress I've seen, but am looking for a reliable one.

I have the same problem, I think it's began after update to pie 9, Is it possible? I try everything like clear cache, factory reset, hitting the camera. What is your solution ? Only change the camera with new ?

Half side blur photo (Unable to focus)

I am not much interested in camera when i bought Mi A2, it works fine. but recently when i was taking picture, it was half side blur and i was not able to make focus on upper side of camera. i tried all modes but no use. I have Note 6 Pro and it's camera functions and focus properly.
in mi A2 I observed when in MANUAL mode i select Lens as LOW LIGHT, it works (but in manual mode only).
do any one has some solution or give reason to behave camera like this.

Same here

It was a February patch bug and it seems to persist in March patch... Xiaomi.

This is a hardware problem, I also had this, give the phone a guarantee.
P.S. sorry for english(

How so we both have exactly the same problem and mine started with pie?

Looks like this is a hardware issue, I'm having the same problem after 4 months of use.

Same here, I also took it to guarantee and they told me it was a software problem, but when they gave it back to me nothing had changed. Camera still not working

I had ordered it from this website but I had paid the cheapest shipping, I'm from Mexico so it will take a while to arrive to my country.. maybe next month..

I had the same problem and replaced the camera module with a new one, and the problem was fixed... temporarily because 3 months after it started happening again with the new camera, so either I am super unlucky, or it must be some other defect in the phone that tends to breaks the primaey cameras...
At this point I don't think I am going to replace it again. Do you know of any way of recording videos with the low light camera?

I have the same issue. In fact this issue persists in the video mode as well. Its okay for videos of objects nearby but move even a few metres away and it becomes very difficult to focus. I was at this concert and wanted to record the performance but only got a very blurry video with muffled sound. For photos this issue is especially an inconvenience when taking photographs of documents etc where you could very well do without the unnecessary bokeh effect. In MANUAL mode this does reduce a bit, but not to any extent that helps.
I was just told by a friend that installing the Google camera mod might help, but I'm yet to try it out.

I have same problem with upper side blur. Seems that switching to "manual" mode and change "lens" from "regular" to "low light", as said by the original user. It works fine with me. Thanks for the tips ! ........ so it is not the hardware problem, it is a software problem. Changing camera may not work ! Don't know if they are going to release new firmware to solve it or not ?? Any idea how to upgrade the firmware ?

If it is a hardware problem I do not see why it would prevent using the secondary camera, it can be a problem with the lenses (Have you thrown or hit your phone?) and not with the module. There are those who have returned to Oreo and the problem persists.

How fix Face ID after replace front camera?

Hello. How to get FaceID to work after replacing the camera module. Are there ways?

I didn't think the front camera had anything to do with face unlock, it's the Soli module that does face unlock.

I suppose you've done a factory reset?

Clear system cache on boot menu.
Do a hard reboot (not reset!)
Clear data of all associated apks including probably Android Services.

I teardown my 4xl and replace rear camera module. After assembling it again, rear camera worked fine, but front camera and faceid cannot work. My phone cannot detect front camera. It show black screen when flipping from rear to front camera.
WHAT I DID:
1. Factory reset -> not work
2. Flash various factory firmware-> not work
3. Changed another whole front camera + sensor module -> not work.
Please help.
Thanks.

It seems the problem is physical... hopefully.
Closely inspect the ribbon cables and contacts of the front cam for damage or misalignment.
Use magnification as needed.
Make sure any ground points to this module were not overlooked. A longer screw perhaps?
The chassis is aluminum so that is a potential grounding point for mounted components like the front cam.
You did disconnect the battery first, right?
I looked at the tear down vid... I feel your pain.

Just like iPhones parts
pixels parts are married to the motherboard each part has a special SN number the motherboard will require
replacing them may cause a problem

So where's it stored? Firmware?
Or does the cam module need to be flashed?
Or both?

What is the trick behind Huawei P30 Pro fingerprint sensor?

Does anyone know what is the compatibility trick behind Huawei P30 Pro fingerprint sensor?
I have got issues with mine.After screen replacement it worked fine,until the microphone stopped working at the bottom board.So i went for a new one.And there the fingerprint issue started.I cant enroll a fingerprint.
I went for another board,new sensors,new main flex.It simply does not work,recognizes it,but does not work.Calibration tools and softwares did neither work.Tried to update/reset,also unsuccessfull. Actually it worked perfectly once,read the fingerprint perfectly,but after restart did not work again.
So,i am stuck... I know in the past i have replaced screens and sensors on P30 and P30 Pro without similar issues.
Is there an trick or must i bring it to Huawei centre to pair the hardware?

Hi,
Did you find a solution for this issue yet? I'm about to replace the fingerprint sensor, but cannot find how I can calibrate the fingerprint sensor afterwards. There seems to be some software app by Huawei which can start the calibration proces but it's nowhere to be found.
Anyone?

Well, i was waiting to get answer from joaofbc but no answer, i didn't try anything on my own, i use phone daily and didn't want to mess it, but face recognition is working fine so i don't care about fingerprint that much.
