It's hiding! Go to the "Puzzles" screen and select "Stats" from there.

I also have a T5, and that little menu worked perfectly during the very early builds (a tap would take me to 'home' and holding it would bring up the menu), but it has gotten 'flaky' as time has gone on. I can sometimes get it to go back to home, but it usually brings up the little menu no matter how I tap it.
