It appears every few times I open the app and the usual android back button doesn't make it go away, and there is no cancel button. What you have to do is toggle the toggle, then the button will change to "do not back up" and then you can press it. It annoys me how easy this makes it to accidentally turn on backup.
google's android camera app is designed to open google's gallery app. Google built an OS that has support for user selected app launching. They built a system that lets an app request the user's preferred gallery app to view photos, but then chose to not use it to force anyone using google's camera to also use their photos app. fuck google
Ya, ran into this one recently. Had to install gcam instead of stock camera on my OnePlus just so I can use alternative gallery.
Android is not truly open source project anymore.
And then if u try using alternative roms - half the cameras your phone has and banking apps are not going to work - Google intentionally castrated the functionality like this.
Was super disappointed to figure this out after installing a different gallery. And AFAIK, there's no alternative camera app that actually works properly, either.
I use Open Camera on my device, there are some very rare instances where it shows an obscure error saying it can't find a gallery app. Most of the time though it opens Fossify Gallery just fine
I'm rooted and Google Photos was removed from my device before a single photo was taken, so never seen or heard even a peep from it
