Who are interested in shooting in raw on this phone? It is in the engineering menu. It works. I decoded the output file. Is a much higher quality than stock or other camera in jpeg. It's clean, unprocessed raw (15MBt)! There is a desire to get the application: to somehow pull (decompiled? Remake) of the module EngineerMode.apk shooting (test camera), add the raw decoder output file into something normal (tiff / png /? /). Decoder exists in the source code (java, but for the computer). Must somehow combine it to get a full application. I do not have enough knowledge of the language. And I can not understand decompile EngineerMode.apk. So I can not do it.
Here are four photos in the archive View attachment test.zip two in jpeg, reaped by the android, and other tiff (converted from raw, untreated, as-is). The only disadvantage we have to somehow adjust the white balance (often obtained images like this, with a greenish tint). What are the advantages: no artifacts jpeg (cubes), more dynamic range (shades easily into focus - see for yourself).
This applies not only to my phone Jiayu G3, but also to the entire platform MTK6577 (maybe more). I think this application will be very popular. Who made it?

Anybody Know how to to convert Debayer Raw BGGR to DNG when I capture QCOM 10 bit Ideal Bayer File I'm unable to decode it with dcRaw I can view it on 7yuV but only the blue channel is visible can't find any Qualcomm Documentation apart from these sources www.androidcodesearch.com/source/device/asus/flo/camera/QCamera2/stack/common/cam_types.h it would be cool to have raw instead of jpeg .

JPG (Joint Photographic Experts Group)
JPG was a filetype developed by the Joint Photographic Experts Group (JPEG) to be a standard for professional photographers. Like the method ZIP files use to find redundancies in files to compress data, JPGs compress image data by reducing sections of images to blocks of pixels or “tiles.” JPG compression has the unfortunate side effect of being permanent, however, as the technology for the file was created for storing large photographic image files in surprisingly small spaces, and not for photo editing.
GIF (Graphics Interchange Format)
GIF, like JPG, is an older filetype, and one generally associated with the internet as opposed to photography. GIF stands for “Graphics Interchange Format” and employs the same lossless LZW compression that TIFF images use. This technology was once controversial (for patent enforcement issues) but has become an accepted format since all patents have expired.
PNG (Portable Network Graphics)
PNG stands for Portable Network Graphics (or, depending on whom you ask, the recursive “PNG-Not-GIF”). It was developed as an open alternative to GIF, which used the proprietary LZW compression algorithm discussed earlier. PNG is an excellent filetype for internet graphics, as it supports transparency in browsers with an elegance that GIF does not possess. Notice how the transparent color changes and blends with the background. Right-click the image to see. This is actually one image that is on four different background colors.
Which to use?
From left to right, these files are: 24-bit JPG Compressed, 8-bit GIF, 8-bit PNG, Full Quality 24-bit JPG, and 24-bit PNG. Note that the file sizes increase in this same direction.
PNG is the largest image type for bigger images, often containing information you may or may not find useful, depending on your needs. 8-bit PNG is an option, but GIF is smaller. Neither are optimal options for photography, as JPG is much smaller than lossless PNG with only minimal loss of quality. And for storage of high resolution files, JPG compresses to tiny proportions, with quality loss only visible on close inspection.
In short:
PNG is good option for transparency and non-lossy, smaller files. Larger files, not so much, unless you demand non-lossy images.
GIF is largely a novelty and only useful for animation, but can produce small 8-bit images.
JPG is still the king for photographs and photo-like images on the internet, but be careful, as your file can degrade with every save.

Hi all, I tried to do some shots in RAW mode. After the shot I have two files: a JPG and a DNG. The jpg is perfect as always, but the DNG File is pixelate and it's very bad. I asked at the Honor official page and they said that's normal because I'm watching it on my smartphone and that on PC the quality would be different, but is it really normal?
To my knowledge, the phone shows just the jpg thumbnail of the raw file (since it would be quite cpu consuming to "develop" the raw data each time). So if you open the raw file in Lightroom or raw converter, it should be fine. Also if you edit the dng on the phone and save the result as jpg, the jpg quality should be ok. At least this is my experience (I use raw mode quite a lot to later edit the raw files in Lightroom).
So there's no way to see a clear image while elaborating it. I will se the good results only at the end.
What exactly do you mean by "pixelated"? And what app do you use to watch the raw image? On the Honor's builtin Gallery app the dng is quite ok quality. If you use a third-party app, it's possible that it cannot dig the best-quality preview from the dng file.
I mean this
While the jpeg is this
I have tried several apps but they either don't recognise the phone's camera app's DNG format or they are simply useless for other reasons e.g. always writing the output to some directory (folder) in the device filespace which one then has to move them out of.
I need something which can convert them from the SD card
e.g. 0000-0000/DCIM/Camera
to the same place.
The S7 is rooted, with SDfix etc.
I would appreciate any tips. Basically I would like an app which works with the Samsung DNG format and which has configurable in and out folders.
Android v6, not v7, rooted.
If you have RAW enabled in camera settings, the phone also stores a JPEG of the exact same photo, so no need to convert them really
Not sure about Android apps, but on PC just load them into your favourite RAW photo editor and export them as JPEGs (Lightroom for example)
Not quite... taking the DNG and processing it with say Lightroom produces a vastly better quality photo.
See e.g. here for examples

The Jpegs from the phone are over-contrasty and over-sharpened. One should never apply unsharp mask until the image is resized to the final resolution (if at all).
Yes I know that, which is why I suggestion Lightroom
Converting on the phone is not going to give anywhere near the same results as PC Lightroom
Use a PC

The real issue IMHO is that all the camera apps are mostly just control panels for the camera API. They don't AIUI get the image to play with. That is why e.g. all of them have the same contrast steps, same exposure range, etc. The JPG is done by the OS and the app gets what it gets. One camera app developer explained this to me.
Is it possible to somehow (via adb or similar) change the default camera compression for jpg and heic to improve the quality of the photos?
Use Expert raw app. Can't be higher than that
The jpg's that expert raw generates are smaller (so I understand with more compression) than the ones that the stock camera makes.
