Unlock Check

See when your Android phone was locked and unlocked. Unlock Check reads Android's own usage events, so history from before you installed it shows up too. It keeps its own copy on the device so the history goes back further than Android keeps it. It has no internet permission.

Install on your phone

1. Open this page on the phone and tap Download APK.
2. Open the downloaded file. If Android asks, allow your browser to install unknown apps.
3. Open Unlock Check, tap Open Usage access settings, pick Unlock Check and turn on Permit usage access.
4. Go back and tap Show lock/unlock history.

Or install it from a computer with USB debugging on:

adb install -r unlock-check.apk
adb shell appops set ca.morristech.unlockcheck GET_USAGE_STATS allow
