Pretty handy app for old devices with a faulty power button. Feature request: double tap to unlock screen (newer Android versions have this, but old devices with faulty power buttons don't generally have modern Android versions available).
★★★★★Keith Wiley· Aug 2, 2026
My previous phone supported a double tap on the screen to lock it. After upgrading. I found this app to be a godsend. I just leave it on the main desktop screen, so it's always there. The problem is that some Android 17 has made this app unusable to the Advanced Protection feature. The only way to re-enable the app is to turn this feature off for the entire phone for all apps forever. The developer needs to make a code change apparently: (isAccessibilityTool="true")

Why does it ask permission to read screen ? You just need to lock, no others. Suspicious other lock apps never ask this.

Before enabling why it's giving alert that it can erase all data?

App no longer works on my fully updated Galaxy S26+. It's completely dead totally unresponsive.
★☆☆☆☆Kimberlee Tanner· Oct 2, 2026
It does NOT work at all. My screen still has full functionality even when it's supposedly locked.
