No worries! If I may, a few other suggestions -
Try not to place buttons too close to screen edges, on "frameless" phones people will touch them by accident.
Also, on many Android phones the navigation bar is invoked by swiping on the bottom of the screen. You have "Poker hands order" button there, so it causes it to open/close all the time. Not a big deal, but it feels like a poor UI design.
And in "Poker hands order", when you tap on little question marks, the text that appears is too small and difficult to read.
