Now i don't know if this is just me, currently im playing through the android version, i have played it on my computer and noticed a few things...
1. On the android version i am currently unable to view any item effects to see what specific items do what, i know on pc version if you hover the mouse curser over the item you'll get a description of the item but there isn't a way to view them on the android verion
2. I also noticed on the android version i am unable to open another players window in order to send them a private message.. to add or block a player.. to send a pvp or trade request anything that has to do with right clicking a player to bring up that window
