Saving parameters on Android app

I see everything on my Samsung TAB 2, but i cannot save the parameter when i want to change this.
How do i do this?
When i’m in the parameter screen i see the value i want to change in green, but what than??? :mrgreen:

I cannot find a “save button” on my TAB 2 either.
So any sugestion is more than welcome…

Did u try the menu key on the device itself?

My galaxy note 3 has 1 physical button (home, etc) and 2 soft keys, menu and back. My other tablets have 3-4 soft keys and there is always a menu/home/back on a Android device at least on my 5 devices.

Good luck.
