Phone security when you photograph and share outdoor projects

In 2019 Samsung pushed out a software fix for the Galaxy S10 after reports that some third-party screen protectors could let unregistered fingerprints unlock the phone through its ultrasonic in-display reader. That episode has long passed, but it remains a useful reminder for anyone who uses a phone as their main camera and filing cabinet for home projects, whether that's a new deck, a pergola build or a council application for a carport.

Our phones now hold a surprising amount of sensitive material about our homes: photos that show the layout of a backyard and where gates and side access sit, site plans, quotes from tradespeople, signed contracts and correspondence with council. Losing control of that information is more than an inconvenience.

Practical habits worth keeping

  • Install system updates promptly. Security patches for biometric readers, cameras and messaging apps arrive regularly, and most fixes only help once they are installed.
  • Check accessories. If a screen protector or case interferes with fingerprint or face unlock, use one recommended by the phone maker and re-register your fingerprints after fitting it.
  • Use a strong PIN or passcode as the backstop to biometrics, not a simple pattern.
  • Strip location data from photos before posting them publicly. Many phones embed GPS coordinates in image files by default.
  • Think about what's in frame. Shots of a finished pool enclosure or verandah can unintentionally show house numbers, number plates or security cameras.

Sharing photos with builders and councils

When sending images and plans to designers, builders or certifiers, use the channel they specify rather than public social posts, and keep originals backed up somewhere secure. Clear, well-lit photos taken from consistent angles also make it easier for professionals to give accurate advice.
