"4. Ditch PIN codes and opt for biometric security."
This is problematic. Biometric data can be compelled against your wishes to unlock your phone. A PIN cannot be via legal precedence. This is bad advice.

Iris data is harder but fingerprints are ridiculously easy to spoof unless the phone also has a built in heat and pressure sensors. All you need is something that the person has touched recently.
