Force JPEG quality to 100% on S20U - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

Hi,
Does anyone know the way to reduce the compression of the jpeg file generated by the camera? surely in stock mode it is close to 96% and I would very much like to increase it to 100% and I am sure that the quality of the image would grow a lot.
thanks to who can help me !!

so you need 100% root to modify the system files

Jpeg on itself is a compressed format. It is always 100% compressed. If you meant by details, you can shoot in raw format which the camera saves every detail it captures.
You'll need to shoot in pro mode though. And you'll need a post processing software to process the camera raw format.
On pc there is adobe lightroom or photoshop for that. For phones there is google snapseed. You can even enhance the photo from these softwares.

Hi, you found a solution?

100% JPEG quality is possible via a build.prop edit
ro.media.enc.jpeg.quality=100
attached is a simple magisk module to achieve this systemlessly if you use magisk (setting is in system.prop in the module due to the way magisk works)

increase camera bitrate?

In nearly every device I've owned, there's been a way to improve the image quality by increasing the bitrate and/or lowering compression, either in the stock camera app, or by a hack or mod.
Is there something similar for the LG OG Pro camera?
I'd like to see how much we could squeeze out of it by increasing the bitrate and reducing compression ratio, etc.
nevermind.
Here's the mod
40MP Panorama, No compression and I can't recall more. It's not my work, found it somewhere around xda but lost the link now.
Don't forgot to backup original media_profiles.xml before using rootexplorer(or adb push) to overwrite the file in /system/etc
**This is not a flashable zip**
Do post your result
Tested on SphinX v 2.0 and Stock KitKat
Device E980

Moto g4 plus camera mod [email protected]

Improved 1080p recording and picture quality
root required
Open media.zip and find media profile xml file extract it and then you can replace.
steps
1) open es file explorer go to device>system>etc
2) find media_profile.xml in etc folder
3) replace it with this media_profile.xml
4) save and reboot.
1) Increased photo compression quality to 100%.
2) Increased video bitrate from 17mbps to 24 mbps can go upto 30mbps but fps drops so 24 is best.
3) Increased audio bitrate to 14000.
4) Increased front camera video bitrate to 20mbps.
5) Increased memcap to twice .
pros
1) Better 1080p video recording from both front and back camera.
2) Image quality of front is improved marginally.
3) In daylight video from rear camera are best .
4) More clear audio .
5) In low light pictures are better than stock.
6 ) sharp and clear video.
cons
1) In low light because of high bitrate video look more contrasted.
2 ) Very small change in picture quality in daylight.
This is screenshot of front camera video bitrate
Does it work in roms too?
Yes any rom
And could it be a way to improve slow motion camera, or default options are the only one??
I got bootloop
edit: nevermind, my mistake xD
I got a boot loop after replacing the file. I'm on aosp extended.
Same here..got boot loop on RR

Use a different app that supports that feature, as the stock camera app doesn't have settings to do what you want.

Enable RAW support for photos in settings for a lossless image file. JPG is a lossy format, even at 100% it still compresses and there's some loss due to that.
Thanks everyone

Raw photography

Hello,
What is the best camera app to shot in RAW so as I can edit?
Do you know a better raw files than the original?
Thanks
RAW files are direct from the sensor! Any app capable of shooting RAW will give you the same file!
Only difference is if a third-party app let you save the 64MP RAW images from the telephoto sensor
Edit - it appears I may be wrong in this statement as others have outlined below.

Ok I asked because with my older OnePlus 5T with GCam has much better RAW files than stock camera.

Lightroom (for Android) is a complete software ..you can don alot from your RAW phone image.
But not free.

Because it's not true what he says. Gcam for example uses a lot of image processing technologies like even before the demosaicing process, that contribute to a better picture. as far as i remember even burst images are melted into the raw picture. That's why you have much better dynamic range and details and noise as in other RAW-Cameras. As long as this is not standardized and enabled via API for all new Phones/Apps, using RAW in Smartphones beside GCAM does not make any sense.
Ok, so for me the RAW from GCAM is way better than the original RAW.... it's not all the same RAW files finally.
The one of the S20 is not really good to me... What do you think ?
Do you think that it will be possible to shot RAW with the Ultra Wide Sensor and the 64mpx? One day...?

Question Question about photo image size

Hi guys, I have a problem regarding Pixel 6Pro photo image size. not sure if any of you might have already noticed.
Image size of my previous Pixel 4XL is generally around 3-4MB. However the image size of Pixel 6 Pro is generally around 2-3MB. Photos taken from both phones are in 4:3 with full resolutions in Google Camera settings.
One more interesting discovery is, once I make any tiny adjustment in edit mode (e.g. increase brightness by 1), the photo size is immediately boosted up to 8-10MB from a photo having original size of around 3MB. Also, I found that the image is not very detailed when I take a steady picture of flower under great weather, when compared to iPhone 13 Pro. Lots of details of the flowers are lost.
I personally expect and indeed prefer having the larger image size right after capturing, as it might theoretically include finer image details.
Hi @junocaj. You can always enable JPG+RAW saving in Advanced Settings, although from my understanding, working with RAW files really requires a lot of professional work, as by default it won't look as good as the JPG (or other image formats - not that there's a choice for other formats with the Google Camera app).
You can also try a different camera app and see if you like the results better, although the Google Camera app will likely have new features from time to time that gives it some advantages. It all depends on what you, as a user, want the most out of your camera app.
@roirraW "edor" ehT . Yeah, I understand that can enable JPG+RAW for professional photo editing.
just that I am a little confused on why the image size of a 3MB picture can be boosted up to 8-10MB right after a super minor editing. It appears to me that the picture size is originally 8-10MB, just that for some reason it is compressed down to 3MB, even I have set the resolution to be full resolution in settings.
Ain't sure if the details of the picture is erased by such compression by the AI. The reason I raised this observation was that one day I used iPhone 13Pro to take a picture at the same spot together with P6P, iPhone output a jpg of around 10MB directly, and lots of details is maintained, while the picture of P6P is around 2-3MB.
@junocaj As to the smaller size of the original file, it could be a change in the JPEG compression they use. Sometimes only lowering the JPEG compression value by a little bit results in a much smaller size while still looking good. Also, the AI possibility as you mention - i.e. maybe on the P6P the Google Camera app is able to routinely save JPEGs at the same compression setting as on previous Pixels but with AI work is still able to reduce the size.
There are several possibilities for the change in size. The new file could be including the editing steps you took - so that you can restore the original. It could also be keeping the edited file in a less compressed state for some reason.
All that above is just speculation on my part.
Sizes of image files definitely aren't the final determination in quality, either. Even a PNG file (not talking about on the phone) can be optimized and take up a lot less space while losing zero data compared to the original file.
I have noticed this too. The P6pros pictures are heavily compressed. I have pictures from my Nexus 6p and pixel 2 that are larger size with fewer artifacts.
One way was to use a Gcam mod that has jpeg picture size selection. At 100% quality the jpegs are 8-13MB. This really does help with details.

@86rickard would you mind sharing where could I get this gcam mod?
I'm guessing Google have set the compression around 80%, mine are always 2.5MB to 4.5MB dependant on how many colours are in the image, very similar to the size they were from my Pixel 5 which given the image is all but the same size isn't a surprise.
I have never understood why all the phone makers cant just include a compression slider and let the user choose. Re-editing a compressed photo and resaving it and it being significantly bigger is par for the course, that's nothing new.
All that said i cant say my photos are absolutely terrible or full of artefacts even after Google Photos has compressed them even further.

Playing with the gcam mod above its about 30-50%. Depending on the details in the image. It looks like the camera app is choosing a compression rate based on details too.
Needless to say in low light, noise reduction and jpeg compression make for a poor image.
@86rickard Great! thanks very much!
Found that the latest version that have the JPG quality option is the Gcam_8.3.252_V2.0_MWP one. Perfect to have the uncompressed output! I will try it out more comparing this mod against the stock gcam, lovely.

the MWP Pixel gcam mod is great (use the first non-beta in the list)
You can force higher quality and HDR+ enhanced (and also change the custom libs option to MWP_xHDR in Mod Settings). this mod is a gamechanger for the 6 series.
I wonder how long it will be before they start sending cease and desist letters to distributors of these hacked versions of gcam like they did for utube?
Another option besides these that will work for a lot of people, is to use alternate camera software. GrapheneOS Camera, for example, works very well. Its not as "feature rich" as gcam maybe, but the default compression is less, and you can override the default by specifying a jpeg quality level.
my p6 pro is my first pixel. i noticed something that might answer your question. when you save a photo after editing it, the default is to save with the ability to revert to original. if you select save as a copy, the original data is not included in the file.

Yeah I think the issue with YouTube was the lack of ads Google was losing money on. There are no ads in Gcam but stupid stuff happens and one will never know what a big tech company may do in the future

Well that's low light for you, unless you are letting the phone do its stacking magic sensor noise as the ISO increases will get worse and worse which then makes everything else a problem. Upping the ISO on a digital camera isn't like it was with film, all you are doing is pushing the exposure which then brings any noise and artefacts to in to view, you aren't making anything more sensitive and it isn't doing anything you couldn't do with the exposure slider in an editing package.
I am sure Google will tweak it in the months to come but i'd sure like the option to lower compression in the standard app or better still save night shots as a PNG so there is no banding in the image, maybe it is time to bite the bullet and introduce HEIC.

HDR+ enhanced has to be enabled. The ISO/exposure adjustment won't work on ZSL (zero shutter lag) aka HDR+. Should work in Night Sight mode as well.

How in the world did you get a photo from pixel 6 pro over 1 MB in size... I took a beautiful full rainbow shot, which looks nice, but when I downloaded it it was only 116 kb in size. Way to small for my tastes. 1036 x 780. Very disappointed and can't find any settings except for higher resolution which is selected.
