Review summary

User reviews are mixed. The app is valued for enhancing lock-screen security by blocking quick settings/power access and is generally seen as functional and protective. However, recurring concerns include the need for device admin rights with uninstall risk, instability or lockouts after reboot, device-specific compatibility issues, and privacy worries about data access. Overall, it’s useful but comes with notable reliability and security caveats.

Pros

Locks the lock screen to block quick settings and power menu without a password, creating a security boost.
Generally functional and associated with increased phone safety; many users report it works.
Positive user sentiment and frequent favorable feedback (ratings like "great", "best", "very good" appear across reviews).
In some cases it remains operational after reboot, showing resiliency of its functionality.

Cons

Requires device administrator permissions and can be difficult or impossible to uninstall, raising security/privacy concerns.
Prone to instability or lockouts: may stop working or lock the user out after reboot or over time.
Compatibility issues on certain devices (e.g., TCL 60 does not work; behavior varies across devices like Motorola vs Pixels).
Privacy concerns about data access: some users worry about potential data access or misuse.

2026-07-24	Ja*****	Pixel 9 Pro XL I was hoping for the best but this app, same as the LOCK SCREEN PROTECTOR app, periodically turns the screen off with no way to wakeup, except for a hard reset. Deal breaker, appreciate the developer but until this is functional on a Pixel phone with latest OS I've uninstalled from both our phones. 3 stars for effort 😊👍

2026-07-19	Ma*****	Does what it needs to do but it often also makes unlocking your phone difficult, since it will interfere with normal unlocking of the phone, so it sometimes will prevent you from unlocking your phone (Pixel10, Android 17).
