Bug in the camera app? - Xiaomi Mi 4i

Hi all,
Has anyone noticed this? When you use the camera app on the Mi 4i in Performance mode, it runs a lot slower than it runs on Balanced mode. I have noticed that everything else works much faster and smoother in the Performance mode, but only the camera app lags. If you switch to Balanced mode, you will notice that the camera works perfectly without lags. It should be the other way round!
Just FYI, when I say 'LAG', I am referring to the time required to switch from rear camera to front camera, switching to gallery, HDR shooting etc.
Can anyone else check and let me know if this is happening?

yes, you are correct. There is lag when switching front to back camera and turning HDR on and off during performance mode. But, this seems like a Software issue (the camera is very sluggish anyways), so there might a future update from Xiaomi for a fix. Remember, MIUI 6 is still very new and still has some issues (RAM management, etc.), so I wouldnt worry too much about it.
cheers!

Camera crashes with RAW and Slow Shutter

The stock camera crashes when I:
-enable RAW
-select slow shutter
-select a shutter speed of 2, 4 or 8s in camera settings
The annoying part is that I have to reboot every time to fix the camera as it seems to be unable to connect again after crashing. Is there any way to fix this without rebooting? There is a play store app but it doesn't work.

Is this with the new update that came out today?

Question:
Stock?
Bootloader unlocked?
Rooted?
Custom Rom?
Custom Kernel?
Any tweaks to the device other than stock?
I'm just curious...if stock users are having trouble, or is it just the tweakers?
Have you tried a factory reset? And as above, any mods or running 100% stock?
Rooted with stock rom and stock kernel. Clearing the camera cache doesn't help.
I'll try a factory reset as some users don't seem to have the bug.
I've noticed that too. I've also noticed two more things:
- 4k UHD + RAW = bad time. As soon as I hit record it gives me a black screen, I stop the recording and it freezes. I have to force close the camera app to be able to do anything with it again. Oddly enough, 4k DCI works fine.
- Slow-mo video + RAW = choppy. The video seems to be playing back at a super low frame rate. Everything seems to have a lot more motion blur too.
Using raw any time there is low light results in camera crash as well
Sent from my A0001 using XDA Free mobile app
rooted, with stock everything. after taking 8 sec slow shutter, when saving it lags, then black screen then crash. then when i reopen all the menu still there but black screen. anything i do from there it will just crash.
I have the same problem as the poster above.
Any clue?
The other problems described here were correct with the latest update.
Anyone with anything on this?
Same issue here. Will it be fixed ever?
Yep, this has been a known bug from day 1 bro.
Just to put my 10 cents, same problem here even in Auto mode.
This is the only issue I have with my phone now. Hoping CM12 fixes it.
Hello, in CM12, as says Spectre, camera works well, but is there way, to fix this problem in latest official CM13.1, or Lineage14? Thanks much
edit: well, sorry, in CM12.1 problem still here, seems aka HW problem... overheating?
No working solutions? ((

[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:
https://community.republicwireless.com/thread/26076
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.

In the one plus one camera app this bug is not there! In all others that I have used its there!

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.

camera shutter lag and autofocus speed

I am using a lava pixel v1 that has a very poor shutter speed which doesnt have settings as well and also very poor autofocus speed and after clicking the capture button the camera takes almost a second or even more to actually capture the image. is there any way out? I tried different camera apps other than the google camera which is the default however there is no improvement at all.
Only the preinstalled camera is compatible with that camera. So other apps will not work or may face problems because of compatibility issues.

Is burst mode broken?

Hi everyone,
I'm facing an issue with burst shooting.
When I burst-shoot photos in mid to low light conditions using the HTC stock camera app, I can see that most of the photos (except the first 3-5 photos) are filled with colorful noise all over them...
I'm using an EMEA HTC U11 128GB model with 1.27.401.5 software and camera app v9.20.9740975.
Am I the only one that facing this issue?
Please refer to the attachments to see the problem yourself.
Left image is the third burst-shot and looks OK.
Right image is the fifth burst-shot and looks very grainy (all the burst shots from the 5th and on look like that)
There is nothing wrong with it. Burst mode does not have the noise reduction algorithms which are available in hdr auto mode. Therefore these shots are perfectly normal in bad light conditions. Mine does the same.

When I capture burst shots on the ported google camera app, all photos are looking just fine without all that densed noise so I think you are wrong. You can try it yourself.
Something is very wrong with this feature on stock camera app on my side, I'm sure that it doesn't need to look like that at all.
I see a clear difference between the 3 to 5 first shots and all the rest, it's like they were taken by a different sensor!
I thought you were asking if your phone has a problem or not, so I answered according to what I understood.
It's how the stock camera app is. It needs some updates to fix these issues, there is nothing we can do about it except waiting.
I do believe that google camera is superior to stock app with good settings in almost every condition therefore I use google camera.

Thanks for the clarification.
Meanwhile I will continue to use burst captures only on Google Camera app.
Hope that HTC knows about this issue and trying to fix this as we speak. :fingers-crossed:

Question Strange post processing bug when zooming on stock camera

Has anyone else also noticed photos come out with weird, massively boosted brightness and everything when taken with 2x zoom or higher on stock camera? Strange thing is even at 1.9x zoom everything is fine but 2x and beyond the photo is basically ruined because of this. Very annoying.
HDR and other enhancements are turned off, yet this occurs.
Doesn't happen on GCam. Any idea/solutions? Thanks
Tried here. No issue. And 2x zoom photo from stock cam was better than GCam 8.3 for me.
Didi you activate HDR and IA options in stock cam?
Yes they're all deactivated. No problem upto 1.9x zoom, but as soon as 2x zoom is engaged, there's a sudden although small change on viewfinder white balance. And final photos look extremely bright and noisy compared to 1.9x and below, as if some weird filter is put on. I've downgraded the camera but still happens.
Btw, bootloader is unlocked, not sure if that's got anything to do with it.
Its interesting if you don't have this problem. What's ur software channel and build number? Thanks
Without this bug, you'll generally get better zoomed images on stock camera because it'll use 64mp crop instead of only 16mp recognized by GCam. But this bug ruins it.
Unzoomed though, GCam's HDR+ is still the best.
Just discovered this thread.
Yes, I have the same problem. But it looks like the effect is not the same everytime. Maybe depending on light (indoors vs. outdoors)?
I noticed it happens when i zoom in in worse scenes. It could be that the automatic camera mode is overcompensating by cranking the iso way too high. Have you tried using the pro camera mode?

Yes, but I don't think pro mode uses 64mp crop like auto mode, just a crop of 16mp, which doesn't have much detail that's required during zoom. Also it's annoying trying to switch to pro mode everytime.
