My little kids (less than 3 yo) like to view photos on my Samsung A5 cell phone. That's great, and they are allowed to do so. I can even pin the screen to make sure they can't leave the gallery app and start deleting e-mails, which is good.
Unfortunately, both the built-in Samsung Gallery app as well as the pre-installed Google Photos app allow them to (accidentally) edit and delete images, which is bad.
Can I somehow make those image viewers "child-safe" and turn off all editing features?
I also tried looking for alternatives, but, apparently, all highly-rated gallery apps have lots of "useful" features (like renaming and deleting files). There are also "kids mode" apps available, but they don't give access to all photos taken on the device and would require me to select the ones I want to show my kids (I want them to see them all).
