Core Functionality
- Intrusion Capture: Secretly takes photos via the front camera upon incorrect unlock attempts and emails them with GPS coordinates.
- SIM Swap Detection: Alerts the owner if the SIM card is replaced, providing the new phone number and network provider details where available.
- Power-On Alerts: Notifies the owner when the device is powered on after being switched off in a locked state.
- Enhanced Media: Captures multiple photos per attempt and records a 20-second audio clip to be included in the alert email.
- Offline Queue: If data connectivity is unavailable, logs are saved locally and transmitted once a connection is established.
Operational Notes
- Trigger Logic: Android requires a minimum of four digits or dots for a PIN/pattern. Lockwatch triggers only after four incorrect characters are entered.
- False Positive Prevention: Alerts are cancelled if the correct code is entered within 10 seconds of a mistype.
- Permissions: Requires Device Administrator permission to monitor lock screen activity. Note that the standard Android system warning regarding data erasure is a generic prompt for this permission level; the app does not possess data-wiping code.
