Topic: Back Key on smart phone screen

I am using Juicebox pro not embedded, and I have set a url for the Back key to return to the webpage that calls the gallery. This displays correctly on my large screen Laptop.

When I display on an Android mobile phone I get the thumbnail only display that I should expect on a small screen, but neither the thumbnail display or the full image display seems to display the Back Key. What am I doing wrong?

Re: Back Key on smart phone screen

Set showSmallBackButton="TRUE" (in JuiceboxBuilder-Pro's 'Customize -> Back Button' section). (The default value for this configuration option is FALSE.)
