Small print in the Go App ?

[The Springs]

Hi, since I updated the GO app from the first one I had( I still might be few versions behind now) I have found the font is very small and it doesn't fill the tablet width or depth making it very hard to read.
The individual battery status display used to fill the screen for a start. Is this some setting on my S Tab ? Can it be changed ?
I searched this problem and did find someone with the same complaint but no answers
Thanks
