This is why I’m paranoid about crypto and cellphones

Was reading this article this morning about a critical update for Samsung Galaxy users with WhatsApp. Maybe In overly paranoid but I have a dedicated airgapped computer I use for only for crypto. Don’t use my cellphone for any crypto activities because of stuff like this. How do other people manage their crypto security? https://www.forbes.com/sites/zakdoffman/2025/09/12/samsung-issues-emergency-update-for-most-galaxy-users/
