So when I opened USAA it said my phone was rooted, and that theyre not responsible for whatever happens if I continued. Now from looking into this it seems like, multiple times, an app has thought a phone with GrapheneOS is rooted when it's not, so I'm guessing that's the issue. But I want to be extra sure that something hasn't happened to my phone that I don't want, so where do I check or what do I do to make absolutely sure my phone isn't rooted?
