I think the picture delete behavior has to do with the google connection. One of the "services" google has on most phones is "automatic backup" onto their servers - especially when you're signed in. Which sign-in remains in affect, once it's done, until you manually sign out. I think you can prevent, or at least reduce, this behavior but it takes 30-40 minutes of very carefully going through the phone options and then going through the google account options. There may be apps installed on the phone which, once they get the sign-on credentials, will sign-on silently every time they come alive. Thus, it's also important to go through all the apps and review their settings and what connections they make in the background.
It's a real pain that I go through once or twice a year. Any new apps I install, I try to very carefully review their settings and permissions. Some apps insist on getting certain permissions in order to install, but after they are installed one can go to the Android "Settings/Apps", open that particular app's properties and "deny" settings which you don't like - and the app will still run, albeit complain occasionally if you ask it to do something it can't reach. I do this routinely, denying access to camera, mic, location, CONTACTS (a big one for me), etc. for those apps which, for my purposes, don't need such stuff. I _never_ allow apps to archive or "sync" with the cloud. And if you use an email app, you pretty much have to be signed in and it can be difficult to find the "sign-OUT" button.
But that's just me and it takes time and there's no guaranty.
