Rear Camera and Flash not working. (Possible Camera Firmware problem)

Ok, the rear camera doesn't open. I can't switch to it in the camera app or snapchat etc. Flash doesn't work either, and if I do the "V" gesture for flash when the phone is locked, it restarts. I have:
* Cleared cache/data
* Disabled and re-enabled the app.
* Dirty flashed OOS 4.1.7 multiple times and have also flashed Franko's Kernel which I normally use (currently running stock kernel though).
* Google camera app multiple times. (had this before too, then I deleted it after this camera problem arose)
Not sure if relevant but TWRP has been giving me some error I haven't been able to fix for some time, and can't delete the file that it says it can't open (through twrp itself or cmd+adb) . Relevant SS attached.
Thanks.

You may want to try to flash the phone using the unbrick tutorial. Make sure you have a backup of internal memory

Hmm, I haven't tried that. I just did a clean install with no success. I deleted everything except USB OTG from TWRP. This has become much harder to fix than it should be . I didn't even do anything to set it off, I was in snapchat and took a pic and then it stopped and the rear camera/flash haven't worked since.

Just to update, I just tried a clean install of NLOS Lineage OS and the rear camera/flash still didn't work. Also, if I try to take any type of video with front camera the phone says "Low memory, adjust the picture resolution or delete some files" even though there's only 3.3 GB of space used.
Also, after a clean flash and wipe of everything the error reported by TWRP no longer exists. So that wasn't what was causing the problem.

Just used the unbrick tutorial. It worked perfectly however the problem still persists and remains unchanged. Anyone have any other ideas?

After some deep diving through forums I decided to use the phone's inbuilt hardware tests, in particular *#808#, as the camera test given by dialing *#*#34971539#*#* doesn't work. Firstly, the flash works through the hardware test (although quick settings still doesn't). The "foolproof camera test" gives BackCamera PASS and FrontCamera Fail. This makes sense as when I go to the individual tests the "backcamera" shows the front camera image, while the "frontcamera" just says "cannot open camera". The PDAF/Cam_EEPROM info test says "FAIL Qualcomm", which I believe is the camera firmware not working. The storage test says "sdcard is unavailable" which I assume is why the camera isn't allowing me to record any video through the selfie camera and says "Low memory".
In summary, how do I fix the camera firmware problem and the sd card error?

RMA your phone, hardware fault.

Ok Thanks.
So there is no way to update/fix the firmware problem?

No.
P.S. "Thanks" button is for thanking, by the way. Use it in the future on this forum, whenever somebody helps you.

Im having the same problem on my one plus 3...did u find any solutions??? if yes plz lemme know.

I haven't found a solution.i replaced both The front and back camera and even played with old/new cameras in different configuration (old front + new back / new front+old back / no front + new or old back and so on) varying the result from "Back camera pass/Front camera fail to both Fail ) .the funny thing Is that if you just remove back camera and do the diagnostic menu *#808# > foolproof camera test it still says back camera pass

I have the same problem... And my camera before of this beta worked awesome... Beta 24 **** our phones...

Experiencing the same problem with the front (away) facing camera and the flashlight.

Same Problem for me since the latest official Beta. Ich tried resetting and reflashing the Phone with the last official stable rom. Did not help.

I think I solved this. I let the phone cool down then i powered it off. I let it cool down a bit again and then booted it back up. The camera and FL work.
It seems that this happends when the phone gets heated, at least in my case.

I have the same problem, camera was working fine yesterday. Foolproof camera test shows front camera fail. But the front camera works

front camera not work (stock camera, gcam camera, custom rom camera)

my problem not solved.
its very hard.
if i switch to front camera (stock camera), its not switch to front camera. it only switch to secondary rear camera.
why?
and, i try with another apps, my front camera is missing.
I've tried all ways, Flasing with stock oreo, pie, custom rom experience, MIUI (convert to mi 6x) BUT ITS NOT WORKING
Clear data, factory reset, and another way, I tried it and NOT WORKING
There is other member tell me "replace front camera module" and i try to buy it and waiting for 2 week. waiting for the front camera module for 2 weeks and after i replace front camera module, ITS NOT WORKING TOO.
WHY?
the age of my mi A2 was not yet 1 month old but it was crash.

Same issue I'm facing, my phone is also 2 weeks old yet.

Same problem in mipad4
Hi guys. I have the same issue in mipad4 plus. have you found a solution?

Same problem, any solutions?

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

Please let us know if this fixes it. I have this problem too and I'm thinking about ordering a new camera module.

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.

Focus issue on main camera with close objects

Hi there, I have an ongoing problem with the main camera on miui 12. My camera works fine with all the shots except for macro photos or when I try to focus on something near. I use both gcam and stock camera app and both results are same.
Here are some example photos. Last one is ultra wide, its not clear because of low Light but it can actually focus.

Up!!! Nobody else has the same issue?

This close focus problem is occuring on my device too, i reset my phone and after using again like a new one, this problem occured ,plz i need a solution

How to solve this issue?

Shockingly poor front camera quality

Hi all,
I recently purchased S20 FE 5g (Snapdragon, india) few days back for my wife. The screen of her previous phone Redmi k20 broke after a fall and screen was not available (and even if so it was going to cost around 50-60% of phone's original purchased value. So instead we decided to buy new phone. And after lot of back and forth we settled for S20 FE.
The main camera is good. But the front camera and selfie is really poor for this kind of phone and price. In fact Redmi K20 which was almost half of the price of this one had better front camera.
The photos are grainy and blurry half of the times. And smoothening effect even after turning off all filters. This doesn't have autofocus I am aware. But most of the phones do not have for front camera.
Night mode and Gcam improves it somewhat but overall very disappointing front camera.
I checked with service centre and they mentioned there are no hardware or software issues. So I cannot get any return or refund as well.
Shockingly very few reviewers mentioned the issues with front camera and overall camera reviews were good. Now after doing some research see many users complaining about front camera. Seen some posts here and many on reddit as well. My 3 years old Pixel 3xl takes miles better photos and even almost 2.5 years old Redmi K20 was better in front camera marginally which was almost half of the price.
Given S20 FE was released almost 1 and half years back I do not have any hope of fixing the front camera by software updates from Samsung (they would have already done by now)
Or if anyone here have any idea if the front camera can be improved by some tweaks? (already tried night mode and gcam which are better but anything for normal shots?)

Is it better than the stock camera?

stock camera and stock camera app are two completely different things. Sometimes custom apps perform better.
You should look at it, then you can decide. I have the luck that I did not buy the same phone..

I bought the S20 FE and back then there was a screen bug that was enough for the seller to take the phone back - you'd have to search for the thread but it involves multi-touch on the screen.
There's an app you can DL to check it but it shows as when you do multi-touch swipes the screen malfunctions. Might work with your retailer as a faulty phone?

I would return it.
Try clearing the system cache and cam data first.
If the cam app has been updated, roll back to factory loaded version.
Also try in safe mode to rule out a 3rd party app causing the issue.

Tried the first and 3rd suggestions but same result. Second one means factory reset?

It's better to find the root cause. A factory reset is the last option. It's used after a major firmware upgrade, if a poorly written app alters hidden user settings or in the case of malware.
Problem being is you never learn what the root cause was... if the issue reappears in the future.
In the long run a conservative troubleshooting approach wastes less of your time. Use factory reset as a last ditch option. Always clear the system cache before you go full nuke as it can fix many strange glitches.
Also try a hard reboot (simulates pulling battery).
Did you do any firmware upgrades?
Did you use SmartSwitch to help load this phone?
If so factory reset. Do Not use SmartSwitch on the next load...

It's called Touch Screen Test - there's a thread on Reddit about it here...
NOTE: Put a www. in front of the addresses and copy them to your browser - if I put the link it posts the entire threads in this post, which seems a bit impolite for others.

I found another thread that claims it was fixed in updates so check you have the latest firmware also.
reddit.com/r/Galaxy_S20/comments/jau31s/s20_fe_touchscreen_issue_thread/

For me i found that i get the touchscreen issue, more like the glide keyboard plays up
Reboot always fixes it.
And its usually after phone has been on continually for days on end that it acts up
As for the front camera, I agree its poor.
I find i have to add colour to the images and chuck on the warm filter to full to get warmth.

I had the same bad luck of buying this phone. Have been facing the same issue. But there is something surprising I have found in the front camera of this device (S20 FE). See the difference between the photo mode and video mode of Front camera. I found the difference quite noticeable. This confirms that there is nothing wrong with the front camera of this device but definitely with its software. In video mode of Front Camera I see no lag as in photo mode and the camera is as smooth as it could be. Kindly see the difference and do let me know.
Regards
