"Back" - Button 

At the moment if you go back from a picture/ comments within a profile you dont get on the side immediatly before (the profile) but on one of the main pages. 
E.g if you go on "community", choose a profile and look a certain comment section of a profile  and then use back you will not get back to the profile but back to "community". 
Same behaviour if you start from newsfeed or trend page.
