How to access inventory on tablet
Top of the screen will be a button that says (Menu) once you open the menu on the right top of the list will be a button that says (Character) then their will be three tabs touch the one that says (Inventory) then just underneath there are more tabs for the different types of of item's.
Selecting is much easier if you have a stylus/phone pen and you may need to touch and hold briefly for some options .
Occasionally the touch input is offset a little bit to the left (that could just be my device) so if your inputs aren't going through try touching next to it.
