Many people complain about UI6.1 navigation, me included.
However, after using it a while, it doesn't seem to be that bad anymore.
Go back the previous page - just slide in the middle of the page from left to right.
Go forward - same, but slide from right to left.
Go home - slide up from the bottom bar
Close all apps, or see all open apps - slide from the bottom bar up to the middle of the screen, keep it there for a fraction of a second, then release. You can switch between apps, close some or all.
Basically all the previous functions are there, but differently.
Bonus, we have the new bottom bar.
Hope this helps.
