Android vs. iOS: Which mobile operating system is more secure?

This is one of the eternal and key questions when deciding which mobile phone to buy:

  • iOS (Apple): It stands out for its closed ecosystem, strict app review, absolute update control, and secure storage of biometric and personal data. Fragmentation is minimal, and users can rely on simultaneous updates for all supported models.
  • Android (Google): Its open nature and customization by manufacturers means that the level of security varies greatly from model to model. Google leads development and provides monthly patches, but each manufacturer decides when and how to distribute them. "Pure" phones (Pixel, some OnePlus, Fairphone, LineageOS, etc.) are generally much better protected than highly customized devices.
  • Notable differences: iOS is less vulnerable to malware and attacks due to its app control, but it still collects a lot of data privacy-wise. Android allows for more customization and control, but requires more advanced users to maintain maximum security.
  • Android has improved a lot: Play Protect, advanced permissions, sandboxing, and new encryption systems have raised the bar, but manufacturer heterogeneity remains a source of risk.

Ultimate security depends on both the system itself and the update policies, user usage, and the specific hardware of the terminal..
