The article I linked mentions work profiles, but I’m gonna be honest, I have no idea what a work profile is, or how it’s related to Multiple users, so I can’t say anything about that.

I don’t understand what you’re saying. What I gather is that this bug happens because of the Multiple users feature, which I assumed was synonymous with multiple profiles.

Thank you. Settings > System > Multiple users, if you want to make sure, but it’s pretty much impossible to enable it without knowing it’s on. AFAIK using multiple Google accounts is fine.

I know that. I don’t really care about my signal or WhatsApp data. That was just to make sure people know how to not lose any data. That is not the part I am blaming google for.

The main point of this post is to warn people so they don’t make the same mistakes as me, and so they know that having multiple profiles can cause your phone to factory reset itself.

I have never needed to load a backup so I didn’t think it was going to be necessary (this was a mistake and I acknowledge that in the post, I am not blaming google), but I do think the fact that you can’t do a full backup onto your own hardware is silly, and definitely the reason I never did a full backup. (Again, my fault).

I put almost all of the Google blaming in a section marked as spoiler and labelled Rant. If you disagree, that’s ok, that part isn’t the point of the post. But I think it’s reasonable to expect that the software in my phone has been tested, at least to the point where it doesn’t do random factory resets, and that if something like that were to happen there should be at the very least an acknowledgement by the company, if not a warning/taking back of the software update that caused it/a fix.
