Android over notification bar

[mikesid39]

Hey guys,
A few minutes ago i opened the Amazon music app on my galaxy s7. Then there was the half of the Android Icon (the green Android) upside down on top of the screen over the notification bar on the left side and a text next to it, which i can't read (bc of black text at black background). It disappears after tapping on screen. What was that? Did someone of you had that before, too?

Can you get a screenshot of it when it happens?

I moved this from the Android Apps forum to the General Help forum since the former is intended for developers to promote their apps.
