Hi. There are some key differences between iOS and Android devices. We can't neglect them and applications need to adapt somehow. One of those differences is the back navigation. On Android you always have access to application manager, home and back button. You can use that back button to navigate back in history - you don't need to reach 3 dots menu.
On iOS you have built in navigation gestures (swipe from left and right edge to go back and forward), but it's convenient for all users, thus we decided to put back navigation in the FAB menu. This however meant we had to remove Reload action.
If you don't like vibrations, open settings and turn them off (this is android specific feature).
