Answer 1

The app was installed in other user. It is seen as uninstalled, but actually it is installed in multi user environment in android. Press the app in the settings, then press again the app to go into the details. Press the three dots on the top right corner of the screen, the select uninstall for all users.

Answer 2

Make sure that you have generated a sign APK. To generate sign APK you have to follow the instruction they have given

https://facebook.github.io/react-native/docs/signed-apk-android

This is not affected to debug build.

If someone still have this problem, try to deactivate in the device configurations google Play protect options. That worked for me.

Answer 6

You should check if there are any files related to the app in your device, i had a similar problem and solved it by removing all the cache data from the device. So, make sure to delete the data/cache of the app before unistalling it.
