[Q] Corrupt photos if larger than 5 MB, using any camera app

Hi,
I'm unrooted, stock V10h.
After noticing that the stock camera photos are very compressed (8MP photos never go above 3MBs) with no option to change that, I installed Camera Zoom FX. All seemed good, but then on a sunny day after taking *lots* of photos, noticed I couldn't view some of them on the phone, although thumbnails were there. Came home, transferred to PC, opened and noticed that the ones the phone couldn't display were corrupted. All of them, had a gray bar at the bottom, some more, some less. Obviously the compressed jpg stream was broken after some point.
Thought it was Camera Zoom FX's problem, because this never happened with the native camera app. Uninstalled.
Still wanting better quality, installed Camera ICS. Great too. But same problem too (on some photos again).
Went on to install Camera MX. Same.
Finally narrowed it down to this:
if resulting photo is > 5MB (more precise: if > 5130 KB) then it's corrupted
(and that's why the native camera doesn't have this problem: there's no way to choose better JPG quality for it to make 5MB photos).
I thought: memory speed problem. But then again, the photos were saved in the phone internal memory. Internal memory is not supposed to have speed problems. Anyway, I tried saving to Class 6 and Class 10 SD card, and the results were the same.
Anyone know about this?
Also, please report if your >5MB pictures are fine (in case you shoot at that quality), and what app you use to take them.
Note: the problem seems to be there with jpg photos in general, irrespective of device. Here's a link of someone experiencing the same photo corruption on a normal camera (Casio EX-F1). The problem with my photos is exactly as in the photo he posts a bit later in the thread.

Ok noone seems to know anything about it.
Could someone at least please report if you can get photos equal to or above 5Mb in size, whatever camera app you are using and whether the photos are ok?
(to get that quality, you must select 8 megapixels and then the highest quality in some other setting. For example camera zoom fx and camera mx have a percentage slider (set it to 100), while camera ICS names the quality (select ultra). Also a steady shot and lots of light is needed for the pictures to go up to 5Mb even in these settings.)

Just tested with Camera ICS.... Same issue as you. Photo was 5,266,434.00 bytes.
Using V10h Euro Open.

i had the same issue on deodexed ICS i had a week after purchase, and after i installed this mod:
http://forum.xda-developers.com/showthread.php?t=1855818
i tought the mod broke my camera, but i guess it was this bug/limit.

Thank you both for reporting. At least now we know it's an (LG implementation?) android bug.
Really annoying to me, as I would like to use the camera's full potential. Hope this gets fixed in the upcoming JB for 4X.
(although in order for something to be fixed, LG would have to know. And this problem surely hasn't received attention since it seems I am the first one to bring it up).

It would be interesting to see what would happen if someone with v20a tested this.

Yes indeed.
On another note, I also checked GeoCam and sometimes it gives an error (not enough memory or something). The photos that it saves with no problem are maximum < 5 Mb, so I assume it is the same problem. But this app demonstrates that there is a way for the programmer to know that during saving the photo something did not go as expected.
Where exactly the bug lies, is another matter.

i might try the mod in official 4.1 when it's out and someone releases a deodexed version, just to check if it works on JB.
this is quite a strange problem we have on our hands, i did some search on google, and haven't found many similar problems.

I too am anxiously waiting for the official 4.1 and was hoping that it would not have this problem.. just wishful thinking..

i already know it a long time ago, and i asked about this at the camera MOD thread by ksekhar http://forum.xda-developers.com/showthread.php?t=1855818. but no one seems to bother

Hello ksekhar. I found a problem in the LG firmware, it appears in your mod too.
In third-party programs (ICS camera+) and in your camera mod of the compression quality jpeg minimum, maximum file size.
In some conditions, such as the leaves in the sun, the size of the file begins to exceed 5 megabytes. Then the problems start.
This file is written to the error (broken jpeg file). I've been thinking why this is so and finally got it.
In your version, you just increase the compression quality to any situation the file size is not more than 4-5 MB.
Also, if you is not difficult, please do me a version (as we did earlier) which fixes only compression jpeg,
but the quality of compression should be a cross between the standard version and your version.
Or tell me how I myself can change the quality of compression.
For example (like photoshop - compression level from 0 to 12)
Original LG camera - compression 9
Your mod - compression 12
The required - compression 10.

i have this problem too
when photo taken exceeds 5MB.. it is broken...and it happened too often. any solutions?

Ok, that's bad...
For now, I check whether the thumbnail of the just taken photo appears correctly (inside the photo application). If not, it's a sign the photo has exceeded 5 mb. Then I go to settings, reduce the quality, reshoot.
Or, one can use Camera MX and set the quality slider to 90-95. Then the photos are better than stock camera, and they don't exceed 5 mb.
Since noone cares for this problem I can only hope the new firmware automagically hasn't got this problem. If it does.. we'll see then...

Bad news... Just updated to official V20a, and the same issue persists. a 5.02mb JPEG resulted in an image which was half ok, half greyed out and corrupt.

Only hope now a mod, or a custom ROM..
Ok, is there a way mother LG can be notified about this? (and don't tell me phone support in my country, they can only handle basic stuff. They won't understand what I'm talking about and respond like "use the official camera application"...)

thanks for the info.
yeah, my country doesn't even have proper support for LG devices. we could try mailing them?

I just noticed this problem yesterday. Is there any fix for this?

Not that I know of.

i have no idea why, but yesterday i took some pictures with my 4x (with the stock lg camera app!).
the most pictures had around 1,5-2,5mb , one hat 4,7mb and one 5,05..
the ->5mb pic is corrupt..

never saw this error on stock, im using stock camera app on my CM
Anyway, i reported this bug to CM on the 4X forum, lets see if they can help. would good if more people confirmed this bug on CM forum..

I have a little experience about this bug.
Last time I flashed google's camera 4.2 with photosphere, camera.tegra.so and libnvmm_camera.so (modded to disable denoise filter) and stock camera. The result was that wherever camera I used (stock, cm, google's) the pic were corrupted (taking photos in dark). Just few of them were OK.
Here are modded .so files - works with CM10.1 (made by me, if you want i can made thread for them):
http://db.tt/2Lfxuehq - camera.tegra.so pasted to /system/lib/hw
http://db.tt/LXdwvJUZ - libnvmm_camera.so pasted to /system/lib
Sth more I will say when I come from holidays.

front camera problems

Hi all,
Sorry to have to post again I have been having great difficulty getting good pictures with the front camera, the weird thing is that when taking the picture it seems a little grainy as you would expect from a 2mp but after the photo has been taken they then change and look really fake looking like I'm made of play dough. I've tried turning all the extras off and it's still happening, help?

Bit of an update, my friend advised me to try getting snapchat as that capture the image straight away and it doesn't go through any processing and yes it's true the pictures taken using this are better.
Is there any camera app that doesnt do the processing as this is what seems to be ruining my pictures. I have tried the stock app, instagram and also pixlr.

Front Camera Video P20 Overexposed / Soft

Hi
Will Huawei fix the overexposed soft image quality of the selfie camera on this phone.
I am still on 8.1.0.103 and wondering if its been fixed in one of the newer updates as it is really disappointing

Not sure they think it's broken, it was obviously designed to do this on purpose. I know a lot of people that use beauty mode. It is rather annoying though as it can't be disabled for those that don't want to be enhanced to Ken doll like proportions lol
If you hit the photo mode rather than the default portrait mode for front camera it does help a bit. Definitely better than portrait mode. I do hope that a future update will add more control over the processing, but I won't bank on it.

I've tried many different camera apps, and the overexposure and softening occur as soon as the camera detects a face. Haven't been able to find a solution yet.

im 99% sure it can be disabled with root - its got to be a setting that detects faces.
we;d need someone to go through the source (if they ever release it)
once i root my p20 ill stalk around to try and find a property.

Sorry, i dont have phone yet. But, if you use some other camera application, will it be the same problem?

Its definitely a setting built into the kernel/source code because using another camera app will not override the setting. It only focuses on the subject (face) and blurs out the background which should not be the case

I have rooted P20 pro, and there is a ton of properties and definitions xml files for different modes and effects in odm/camera folder. For example there is something called "casiobeauty" among others But, to mess with those parameters someone has to have knowledge. So, i guess effects can be modified, if there ever will be someone of knowledge and will to do it

You all may want to install CameraMX from PlayStore.
It gives out high resolution and high qualoty images. Selfies taken by it are noticeably sharper than the p20 pro stock camera. Also, there is a slider to adjust exposure for the front cam (something that is missing from the stock). In addition, the app also supports HDR for the selfie cam as well.
You can give it a try...

What region? I am currently using the .120 for C636 but there is still the annoying overexposure and lack of details esp in groufies

You all might want to use the CameraMX app... I use it on all my selfies now. Ive compared it with the stock front cam and it's way way way better. See for yourself...

Uploaded the wrong photos the last time sorry..
For the photos below, the washed out one is taken with the front camera native app. The better one is with cameraMX app.
Note: No editing done, same lighting condition, almost the same hand position, same angle.
It is very evident that the native camera app is washed out/overexposed.
Well, the CameraMX photo isnt perfect but for me, it is 80% better than the stock camera.

Hi - Is everyone certain this is a SW issue? I don't know a ton about cameras but is it possible there are defective front facing cameras on a bunch of these devices?

Hi, I'm pretty much sure it's a software issue as the original photo can look so much better when you edit it. And, you can also use other camera apps

There is a workaround on the overexposed p20 front camera images using the Google Photos Editor App
(I've read it from another XDA thread).
The results are stunning! It's almost as if the photos were taken using an actual Google Pixel front camera! (In my opinion)
I suppose the image enhancement algorithm for the Google Photos app is similar to the image post-processing of Google Pixel phones.
Note: Google Photos is commonly preinstalled along with Gmail, Hangouts, GMaps.
Step 1 - Snap a selfie using the native app
Step 2 - Preview the photo and click the (...) at the bottom right
Step 3 - Click Advanced Edit ---> Select Google Photos
Step 4 - Select the second icon next to the filters menu.
You will find 3 sliders (Light, Color, and Pop)
Step 5 - Slide Pop all the way up, as well as Color.
You may tweak the settings more for Color and Light too!
(There are more options when you expand it)
Step 6 - Click Save.
Find sample photos below:

Just got a P20 Pro and this is seriously my biggest hate with this phone! The rest is great (except my google pay not working) but the front camera makes me look like a ghost on any image!

I'm on update 128 and the front camera still overexposed.

Why don't instagram stories go up in 16:9?

I come from many 9:16 Huawei phones and an iPhone X and in these I never had many problems with uploading stories and that the sides were cut, but now I notice that in my p30 pro it becomes impossible to upload 9:16 videos to instagram, I cut the videos and photographs completely, I need 9:16 upload for my work, since I am a community manager but I can't upload videos in these dimensions, is there a solution? force instagram to 16: 9 or just change cell phone?
Sorry my bad english.

Image processing suddenly disappeared from snapchat and instagram

So we all know that image quality of pictures taken from snapchat and/or instagram is generally very bad when compared to stock cam right? Especially for androids. But I was seriously very surprised to see that my note 9 was performing very very good in terms of sc and ig pictures.
Normally in androids, snapchat takes screenshot of the viewfinder, but my sc used to process the image, like the image viewfinder was showing was of bad quality but once i clicked on capture button it processed the image and you couldn't tell the difference if it was taken from stock cam or not. Seriously I was loving it and I was alot surprised.
Just additional info : This significantly better image processing only worked when I wasn't applying any filters,or recording video, or boomerang or anything other than normal pictures.
So now since like last two weeks, I have been noticing that the image processing is gone, in both apps, the images captured are the screenshots of viewfinder.
Now the twist is that its still processing some captures; not all. After experimenting alot I figured out what it is processing now and what is just a screenshot, so if I focus on something then take picture, it only captures the screenshot, and if I open up snapchat and just point to an object and take picture without tapping for focus or anything, it processes the image. Seriously if there's anything I can do bring it back like the way it used to be, that'd be great cos I loved that feature. It was amazingg.

Sheesh that guy must be blind. I managed to fix the snapchat processing issue by installing an older version of the app (11.9.0.51), anything past 11.10 seems to break it.

I really prefer to take the photo using the stock camera app,
and then post the photo to another app.
The stock camera app has too much settings than other apps.
It's just a suggestion.
