Best security practice for android users (opinionated):

- Restart Mobile 1x a week (wipes memory, and potential Malware)
- Keep it updated 
- Use a DNS firewall (NextDNS for example) 
- Shut down mobile when traveling in risky areas
- Get a Pixel 6+ (the only model with resistance to offline attacks, see image)
