Security problem with screenshots

[trikaphundo]

The problem

The application does not allow screenshots on the main activity, the activity listing all the entries for which you have OTP setup. But screenshots can be taken in editing activities, where all the sensitive information of entries is displayed.

Steps to reproduce the problem

1. Open FreeOTP+.
2. Try to take a screenshot (Android will prevent it).
3. Select an entry and edit it: entry -> Edit.
4. Try to take a screenshot (Android will not prevent it).

Other related issues

The problem here is, not only the possibility to take screenshots, but the information that is displayed in the activity: secret should not be visible at all!

Agreed. All screens should prevent screenshot.

I think the choice whether to allow screenshots or not should be up to the user. Even my banking app and password manager provide respective options.
