- Screen lock: use a code or fingerprint, and don’t share it with anyone.
- Apps: go through the list and delete anything you don’t recognise. Some spy apps hide behind ordinary names.
- Location: turn off location sharing for apps that don’t need it, and check whether you are sharing your location in Google Maps or Snap Map.
- Photos: they carry hidden information (place and time). Turn off location saving in the camera.
- Backups: check who can access your iCloud or Google Photos.
- Updates: keep your system and apps updated; updates close security holes.
