5rlyn You are assuming every single application is going to stop working, or at least a lot of them
Banking may become an issue, but you can still login through the website, Ticketmaster has its website as well.
"Work and my graduate program expect me to have certain apps on my phone", some people don't have a cellphone (or a dumbphone), I would recommend asking what to do in a situation like that
Discord/WhatsApp also works, I don't think they use any integrity checks anyways
The main issue is going to be apps that want a controlled env, like banking and DRM content (Netflix)
