Front camera crashes pixel experience (caf) - Xiaomi Mi Mix 3 Questions & Answers

Hello, when i open my front camera it crashes, like it works for second then it crashes in 3rd party apps, in the main camera app when i open it its just going home.
Sometimes if i open it too many times it starts working normal but like for example if i leave it overnight the next day it doesn't work
Also from the experience with it when the camera is seeing only one color for example white or when the slider is closed (black) it works but if i show to it more details like the smallest one she just stops and it is bringing me to the homescreen
Please someone help its really annoying

Which camera are you using?

[Q] Front camera exposure bug

Hello guys,
I don't know if it happens to you, but I've got some ugly bug on my front camera. Wherether I'm trying to shoot photos, I've some good exposure in preview, but after I shoot a picture, the exposure goes under or over exposure, but never the one I get on a preview screen (before hitting the button). Is this a known bug and is there any way to fix it.
I didn't see anyone complain about it, so I think it's not common. By the way, I tried to use different roms and diferent camera apps, it all the same.
The only thing I found on the internet is this site:

Yea, it's a common bug, that haven't been fixed.
To me it only happens in very good daylight and the photos end up overexposed, HDR doesn't help.

So I have this bug too, any pictures taken with the front facing camera outside during the day are almost entirely white, you can just about make out what the picture is of. But the preview and movies taken with the front facing camera are fine suggesting it's software. I have no screen protector, no case, unrooted, KitKat out of the box. Tried different camera apps with no difference.
I know this was posted a while ago but any updates on this? Can lollipop change anything? I have a moto g LTE in the US so no L for me yet. Can I adjust settings in the camera app (I downloaded the apk for the moto camera that has settings access)?
This issue, along with the multitasking problems that mean I can't even listen to music while surfing, have tempted me to give up on this phone entirely.

Dunno if it's fixed in Lollipop, but I can test. I just don't use the front camera much.
I got no such problem with multitasking at all, even on Lollipop, let alone KitKat that was way better in the memory management.

Thanks for offering to test it - I'd really love to know if L makes a difference. I don't often use my front facing camera either, but just knowing I don't have the option to use it is seriously off putting. Last week I ran into a friend of mine I hadn't seen in years, and after trying to take a picture together you couldn't see either of our faces. It was so disappointing.
As for the multitasking, it seems like some phones have an issue while others don't - all I know is that when I have Google Play open, launching Chrome causes Play to close after 30 seconds, no crash error or anything. Same with the home screen having to redraw after exiting almost every app I use, and Chrome tabs reloading every time I switch between them. I've gone as far as uninstalled the memory hogging facebook and other apps, but the problem persists. Painful is the only word for this phone at the moment.

Tested and I couldn't reproduce the bug on 5.0.2. It takes pretty normal pictures now.
Can you tell me if on KK you can enable HDR? On lollipop this is not accessible at all.

I have hope for the lollipop update then! Yes on Kk you have three options for HDR, on, off and auto.

Does s8+ camera need a second to be fully stable

hey
once i open the camera, specifically from a third party app (snapchat) ...I noticed colourless blackish lines moves on the screen just for a second a 2 and everything is stable after that.
For eg if I make a video in emergency, without waiting for camera to be stable, the video will show few right moving lines for a a moment at the inception nd then its all good.
The samsung main camera also shows moving visions if looked closely upon starting but is not that prominent
Is this some sort of camera adjustment at beginning or defect?

Instagram stories and front camera problems [Lineage 15.1]

I've searched here and on other forums but can't find an answer to some camera related problems.
I'm using 15.1 Osprey June, 1st build on my Moto G3 2Gb Ram (XT1543).
PROBLEM 1: front camera not working.
This is happening for a long time, since I was using stock ROM (my phone came with 6.0, but that time both camera worked fine).
Don't know when this starts, cause i didn't use front camera very often, but when on 6.1 this already happened, the change camera icon simply disappeared.
I've tried all tricks, format the phone, boot on safe mode, clear chaces, etc.
I've used Lineage 14 for a while and now I've made a clean install of 15.1 and same thing.
Back camera works fine for photo and video using Footej Camera — the first time I opened this app, there was the change camera icon; I clicked and get that camera error message, and now the icon disappeared again. Installed MotoCamera_Mod_6.2.5.16 and same thing: back camera fully functional, front camera no icon or options.
Didn't drop my phone, but i'm considering some hardware problem.
Anyone has a link to a DIY fix (or at least try)?
Here in my country, the cost of the repair probably does not pay...
PROBLEM 2: Instagram stories not working
photos works fine, a click the button and can add to my story, but when I record video, after it's finished the buttons doesn't appear and the app freezes.
on "hands free" the image freezes during record, when try to make a boomerang "an error occurs" message appears and the **** goes like this...
I've removed and install back the app, have the last update, etc.
Is someone else having this problem?
thanks!
problem solved!
if someone else is having similar problems, here's the (obvious) solution:
just do a clean flash!
I did it and everything is working now (instagram stories, other camera apps functions and GPS).
except the front camera, probably due to some hardware stuff.

Snapchat - Push screen down notification + other camera queries

Recently got the Mi Mix 3 and having some quality of life issues with the camera.
Firstly it doesnt seem to play well with Snapchat, in that if Snapchat is set to currently use the front camera the notification "Push the screen down to open camera" does not go away, so even if I am just chatting or something, that is there. Any ideas how to remove it?
I am also wanting to leave the slider gestures on so that when I slide the phone down it will open the front camera in the camera app. However again this does not play ball with snapchat or whats app, it will automatically open the camera app even if another app is trying to take a photo.
Any ideas how to fix either issues?
For me the notification goes away after a few seconds if I don't touch the phone
I keep the camera orientation on the back camera for those kind of apps. Then it won't bother me until I need to use it. But if you want to keep it on the front ig it's something we just have to deal with. At least it goes away though.
I also have my slider settings to open the camera and it works fine when I have other camera apps open. Just need to make sure you've turned to front camera in app before you slide.

Yeah I have got used to it. Do you have your slider options set to "Take a selfie"? When I do that even if Whatsapp is on front camera and slide down, it opens the camera app itself.

Is there actually a method (with root or flashing ofcourse) to get rid of it altogether?

Yeah they're on 'Take a selfie ". And I just checked that out on my Whatsapp and it opens the camera within the app. I don't know why your device seems to be doing that.

Front camera not working after installing custom rom. Please help :(

So I just decided to unblock bootloader, recovery and all that stuff to get on the custom rom.
Have been tried 2 rom: Evolution X and Pixel Exp
The rom seems to be working perfectly fine and the camera app as well but when I switch to the front camera, it just crashes all the time for any camera applications, I can use the camera and toggle the front camera then slide the phone down a bit and actually seeing the camera works through the small light gap appear on the screen but as soon as the slider full slides down, the app just stops right away without any warning.
How do I troubleshoot this ? Does anyone here encounter the same thing ?
I facetime my mother a lot so this really sucks for these recent couple of days already. Should I switch back to og software ?
If your on EvoX and use this camera: https://www.celsoazevedo.com/files/android/google-camera/f/changelog590/
When you slide down your front camera should work immediately.

Just swap back the rom and tried the app. Well it still doesn't work. Its go black screen for a sec and close the application.
None of the application with front camera works as well.
Is this a common thing ?
No, it seems like you are the only one with this problem. If it above does not solve it, I don't know.
This is a known issue. Start the camera, switch to portrait mode, then switch to FFC. It works fine with the latest Google camera port than with the Xiaomi camera. Once the app has crashed, to recover it, dismiss the app from Recents.
I had it too i switched back to stock then i formated from twrp then if you don't know what to do when you dont have an os don't freak out just connect it to the pc and drag and drop the files/rom into the phone install and you should be good to go
