Why it does not unlock the screen?
No app can unlock the screen at this time. When you press the power button your phone literally sleeps. In this situation no app (including this one) can detect whether you double tap to the screen.

Why it does not work with biometric security?
Biometric security technologies such as fingerprint and face recognition does not work with the app due to Android security policy.

Notes
- This app uses device administrator.
- "DTTL" is the abbreviation of "Double Tap To Lock"

How can I uninstall?
Go to device administrators under security settings and deactivate "Double Tap To Lock" then uninstall like an usual app.
