Hi there,
Greetings!
I have read your project screen and I would love to fix the specified functionalities of blocking unwanted app installed on phone, prevent installation of apk from play store, on a standalone mobile app for Android devices (Phones) that has already been created (I have the Gradle based source code for the apk). There should also be custom page for blocking of the websites and for Accessibility permissions and the App uninstallation prevention feature should also be added. I've also checked attached images.
I have developed many android and ios apps by Native, Hybrid(ionic Flutter,, React Native) for 8 years.
If you want to see latest portfolio please contact me on chat and discuss this?
regards
Bharat S.
