Front Camera Problem - Can't Connect To Camera - Xiaomi Mi MIX Questions & Answers

I just bought this phone. When I try to use the front camera I get an error: Can't connect to camera.
I've searched.
I've rebooted.
I've force closed the camera app.
I've cleared the cache and data.
I've flashed the Global Stable ROM.
I've updated the Global Stable ROM.
I've rooted.
I've tried freezing and uninstalling the stock camera app and replacing it with a third-party app.
I've tried flashing a different ROM. (Total failures, btw. Nothing but Error 7 issues.)
I've tried everything I can find that tells me how to fix the issue.
Is my camera screwed, or does anyone know of something that can fix it?

That sounds like everything I would have tried too. Some phones have hidden diagnostic routines in them. I wonder if this phone has diagnostics..
Honestly though, I'd return it before it's too late because it really should have worked out of the box. That camera sounds broken.

Settings » About phone » Tap to kernel info 4 times to get into hardware test, if you mean it by diagnostics. 27th line tests front cam; no idea if it makes sense since it launches the camera apps.
Mi MIX
7.5.4 Épic

Yeah, I've tried that too. Even in diagnostics it errors. Pretty sure the camera is either not hooked up or broken. I spoke to a US rep for Xiaomi. They won't warranty it because it was never launched in the US and I purchased it from a guy off Swappa. I guess I'll either have to live with it or open it up myself. Replacement cameras are $27 on AliExpress.
Thanks for the help.

Problem with Front Camera

I already install UltraPop ver1.3 and ver1.4.1 with ver 1.3 before It's still ok. But after about 3-4 days using this. the front camera stop working. and then I flash ver 1.4.1 but still my front camera can not work.
The back camera is doing good, but when i change to front camera it's freeze and then crash. Does anyeone have this problem like me. Or someone know how to fix this. Do I need to flashback to stock rom?
Thanks you.
The front camera may be damaged. You can clearing out the camera app's data and see what happens. If not, you may need to replace the front facing camera.
I had the exact same issue with mine after a month of having it. I formatted and restored factory default and brought it back to sprint store. They replaced the camera and it still didn't fix it so they ordered me a new one. Worth mentioning I didn't pay the $75 repair fee, I don't have insurance, they just replaced it for me completely free because it was a manufacture issue. They did mention that I was supposed to go through LG for this issue but they didn't hassle me. Also worth mentioning that my device was not rooted and I had made no changes other than downloading normal apps.
Edit:
Check out this thread by soulysephiroth, explains that this is a known issue...likely unrelated to the changes you made.

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.

i am seeing when i open camera ,camera failed
can anyone advise on how to fix?
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.

Warning: Camera Failed

So this randomly started happening the other day, whenever I try and open my camera through any method, double tap power, use the app, from the lockscreen etc... it loads than says "Warning: Camera Failed" and there' an OK button that exit's the app. I've tried everything I've found online, factory reset twice, wiped cache partition, and safe mode. It also doesn't work with other camera apps. Another thing I've noticed is that the flashlight is highlighted with a light blue in quick settings but you can't turn it off or on, same with NFC. I didn't drop it or anything, I also bought it used and when I got on Samsung support the person said that they couldn't find the IMEI in their system so it's probably not available for service. Any suggestions? The only idea that I have left is that one of the third party camera apps that I downloaded said something about the camera being in use by another application, any possibility this is actually correct and I can find out what's using it? Other than that I really have no ideas
Did you dropped your phone? There's a possibility that the camera cable got disconnected form the mainboard
try the camera without your sd card. I had same issue on s7, caused by faulty sd card

I didn't drop it but I'm thinking this might be the case somehow as much as I don't want to admit it. Samsung support (however useless they were) were pretty adamant that it was a software issue.
This is becoming a widespread issue:
https://us.community.samsung.com/t5...lfie-camera-on-Note-8-not-working/td-p/208206
This may have been caused by the CRHA update that added AR Emoji and Super Slow-mo:

1.*#34971539# Do you get a menu? and is the phone to cam FW Write greyed out?
2.*#0*# Mega cam test works fine?
This issue is so strange, I have note 8 with same problem when phone is on full Stock Rom even *#0*# cam test fails reads 0 cam. However when I installed Combination Rom (Factory Binary) The camera/flash works fine in the *#0*# and even in more extensive testing menus(Its stock in combination ROM or you can use Info phone Sam app), But I don't know how to flash FW for cameras , since the options are greyed out , I believe I have to place camera FW files (get them from system image?) in a certain folder in root directory(using root explorer) then initiating *#34971539# to enable Phone ---> Cam write, anyone who had this done successfully or experimenting too, your input is appreciated.
Note: When I flash stock rom back, the same problem occurs.

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.

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.

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.
reddit.com/r/Galaxy_S20/comments/j6cdu0/s20_fe_5g_smg781bds_has_a_touchscreen_hardware/?utm_medium=android_app&utm_source=share
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
Robin Arora
