Phone Doctor

A security check-up for your Android phone. Plug it in, press one button, get a plain-English report.

1 · Get the phone ready (2 minutes)
  1. On the phone open Settings → About phone and tap Build number seven times.
  2. Go back to Settings → System → Developer options and switch on USB debugging.
  3. Connect the phone to this computer with a USB cable and unlock it.

Menu names differ slightly between brands. Phone Doctor reminds you to switch USB debugging off again when it finishes.

2 · Run the check-up

Your browser will ask which device to use. Then the phone will ask Allow USB debugging? Tap Allow and leave "Always allow" unticked.

What it checks
  • Apps that match published stalkerware lists
  • How old your security updates are
  • Rooting, an unlocked bootloader, and switched-off system protections
  • Screen lock and storage encryption
  • Apps that can read your screen, read notifications, or act as device admin
  • Apps installed from outside an app store, and what they can reach
  • A proxy that routes your traffic through someone else's server
What it does not do
  • It is not antivirus. It does not inspect what apps do, only how the phone is set up.
  • A clean report does not prove a phone is safe. Advanced spyware is built to hide from checks like this.
  • It does not read your messages, photos, contacts or files.
  • It does not fix anything for you. You decide what to change.
