Firstly, why Android I?

Why yes:

  • It is open-source - easily and completely auditable what is crucial for security (iOS, Blackberry, Windows Mobile are proprietary closed-source platforms) - you know there isn't anything hidden that might violate your privacy (e.g. Carrier IQ)
  • There is a "privacy-aware" Android distribution - Lineage OS / Replicant that has removed any Google spying functionality & includes incognito mode, torification etc.
  • It supports all advanced Linux security features (e.g. SELinux, full disk encryption, etc.)

Why not:

  • iOS marketplace is more conservative, it may contain less malware/trojans than Android app repositaries
