Removing compression from whatsapp - Android Q&A, Help & Troubleshooting

How to remove compression from whatsapp pictures. I tried a method with editing whatsapp_preferences file and setting the image quality to 99 but that doesn't seem to work. Any other ideas? Thanks

If you send the image as "document" instead of as "image", the image is not compressed.
I hope it helps

Camera - RAW - Kernel

Well, i read somewhere that most camera settings and capabilityes are Kernel related.
We hav ea very good movile camera but we can only enjoy the 75% of its power... Adding to the kernel RAW image format would be freaking awesome.
Is possible to add it?
Since everyone uses a different file format for RAW photography,it is not possible to use "The RAW format".
Another good option would be BMP.. notcompressed image file XD

Mainly, on file size affects images and sounds used in the application. You can compress it's more using special programs for compressing sounds and images.
Also, using of ProGuard decreases size of apk file.

Trim.txt on bootanimation [HELP]

Anyone know what is trim.txt on bootanimation?
can anyone explain how to use it and how to make it ?
Because I see the PA (Paranoid Android) rom bootanimation using trim.txt
You can download from here https://github.com/AOSPA/android_vendor_aospa/tree/sapphire/apex/bootanimation/media
in the folder there are also images that do not use a background
Is there anyone here who can explain in detail to me? Or can you make me a video how to use it until it bootanimation ?
The documentation is here: https://android.googlesource.com/platform/frameworks/base/+/master/cmds/bootanimation/FORMAT.md
I tried to get trim.txt to work but even when you specify background in desc.txt it doesn't seem to work, at least on my system.
Although I looked in bootanimation -> libbootanimation.so and it seems to support trim.txt
Edit: So I solved it. None of the files inside the bootanimation.zip may be compressed.
The PNG files obviously don't need it, but if the text files (like trim.txt) are compressed they will be ignored.
Usually desc.txt is so small that it will not be compressed, but while trim.txt is longer (and repetitive) it could be compressed.
Easy (-est) solution if your zipper is stuck? Rename trim.txt -> trim.jpg, compress as usual, then hexedit the zip in two places to turn jpg into txt.
The attached file is an example of trim'ed animation. It's designed for 1072x1448 so smaller screens will not see anytihng.
OTOH, this will work with any size display if you adjust the numbers in trim.txt
(It shows a countup in the lower right corner.)

Exif/metadata accidentally changed, how to edit them to previous data in bulk?

I uploaded lots of files to the Google Drive, after the upload all the photos were tagged with 'Today' as the date of upload. How can I fix this rather than going one by one? I found some exif viewers so I can view the original creation date, then I can edit the files metadata on a file editor. The problem is that I have over 5000 files, so I can't do it 1 by 1.
Any idea how I can copy the original creation date to the modified date in bulk?
Thanks.
All the suggestions seem to only work for images.
@CXZa
Any idea?
