4. I recommend it for youI got this app, and in the course of using it I was looking for faults in it like in many other applock apps I had tried, but interestingly I found no faults in this app.

5. Would love to give 5 star if its working properly..the password screen is popping eveb when any notification is coming for the locked app.

6. I hope dev fixes these issues because this locker really really nice.your app is in need of improving when screen or apps are locked i can still go through them .

7. I have to open the mydevice app first and then it starts working on other apps.

8. Other than that it's good.

9. Otherwise its not asking for password on the other apps.

10. 1st the app should have administrator enabled but it doesn't have that feature so this can be force closed/uninstalled and it doesn't relaunch unless you launch it.

11. Why does the fingerprint ID not work with Android 9? It's irritating me.
