It can be done with adb:
You can if you use adb shell:
Developer Options > USB debugging turned on CMD prompt > adb devices Allow connection from the PC prompt on phone
Then add shell pm uninstall --user 0 com.sec.android.gallery3d
This will remove Gallery, BUT… The stock camera will not allow you to view the pic after you take it (it will show up in Google Photos still)
To restore the above removed app:
cmd package install-existing com.sec.android.gallery3d
There used to be a website called exitreviews.com but it redirects to looria.com now, which is an actual company and I can’t tell if there’s bias or not.
It used to be intended for reviewing any product (usually upon failure).
