Having made a password visible in the Keepass2Android app, if the screen saver locks the Android screen (for example, while I am typing in the password on another machine or if I am interrupted by a phone call etc.), the Android OS automatically makes a screen capture of the app and uses the captured image in the application selector. This makes the unmasked password visible in the application selector (the choice of currently running applications), even if the Keepass2Android database itself is locked, for example via the Android notification "Lock Database" button.
Keepass2Android should not let the OS make screen captures of passwords.
