📜 "We are the Original Good Lock—started before the rest."
We are often misunderstood as a clone because we share a name with a corporate service, but we are the Original Service that launched first and paved our own path.
Today, as an independent developer, I pour my heart into every detail using advanced AI tools. We ask for your support over misunderstanding.

[App Permissions Guide]
We request the following permissions to provide a seamless lock screen experience.

1. Required Permissions
- Display over other apps (Overlay): Essential for displaying the lock screen and providing uninterrupted service.

2. Optional Permissions
- Phone/Contacts: To enable direct calling and contact integration in Mini Home.
- Files & Media: To save wallpapers and use your own photos/videos for customization.
- Camera: To operate the flashlight directly from the lock screen.
- Calendar: To display Google Calendar events on your widgets.
- You can still use the app's basic features even if you do not grant optional permissions.


[Android Version Check]
Works on Android 6.0 and above.
We recommend updating to the latest OS.
To reset permissions, please uninstall and reinstall the app.

Use more ram than the previous version and always appears in the 'recent app' page. The previous version was never.

We apologize for the inconvenience. RAM usage has been optimized in our latest update for better performance. We implemented the 'Recent Apps' visibility for standard usability, but we are open to re-evaluating this based on your feedback. We’re also leveraging AI to further stabilize and refine your experience. Stay tuned for more improvements!

Very nice and cool...but it lacks some important things like Always On Display Future does not work as it should as the screen does not appear directly when the phone is locked, rather you have to open it on the lock screen for it to appear...and the music player also needs some work as it should be There is an option to choose the music player from the phone and not just create a new list within the application. Also, the design needs some re-measurement, but in general it is good.
