Android version: how to use the 3rd flipper.?

[Mad07]

how I can use the 3 Rd flipper?
On different table there is a 3rd flipper available (most of them in the left upper corner). But how can I use them?
I haven't found any place on the screen to activate them
e.g. (the ball hang at this position

Its a bug. It did it to me yesterday. The flipper will work when the wonky robot voice says "shoot for the center". I am confident they will fix this in the next update. Zsolt checks the bugs listed on this forum when fixing up new updates. You can use the 'call attendant' button when this happens to you

on other table, the 3rd flipper doesn't work, too. Not only on robot...
