This application and your ideas are good. But I have experienced some security issues. I locked my 'File Manager' with this application. When I try to open it, it will only open after I press my volume key up to a certain time that I fixed. But if anyone tried to search any files keywords, then it will show the concerned file and it can be viewed or played if it as a video file. Remember...it is a application locker. Then, how this type of files are protected...?

This Apps is good, its worth using it. I've tried many other Apps but non other Apps can be compare with this. But one setting needs to be update, ie. APP LOCK SETTING. In SCREEN LOCK , we have Screen lock style ( Default, Black, Transparent and Custom ). But this is not applicable for APPS LOCK , and I want this SETTING in Apps lock too. Besides VIRTUAL BOTTON is too limited, if we can place on our own desired position will be Awesome.

I am a big fan of your oops app lock. But now with my new phone with android 10, I am facing an issue. Here's the scenario. 1. Lock an app with oops app lock 2. Open the app 3. The app does not respond. It will unlock only with volume key combination. Until this point everything looks fine. 4. Now I press back button 2 times and open the app again. The app works normally. So the app lock is defeated by pressing back button 2 times. This happens only in android 10.
