A couple of days ago I logged on to Facebook on my Samsung Tab 4 and an 'update app' icon appeared which I duly clicked.
Now the page isn't full screen, with a trending subjects column on the right taking up a third of the screen.
I have tried to look for a setting to disable this but to no avail.
Can it be disabled and return to full screen?
