The back button (seen at least from when moving from card search results back to search) is difficult to reach quickly on most large phones. Some other apps (such as apple’s safari browser) additionally support dragging from the side of the screen to move back, increasing accessibly and speed of use. Would be nice to get this in a round of UI tweaks.
True. Let me add that when clicking on a card and seeing it’s detailes: the back button (arrow in the top left) and the close button (x in the top right) are confusing. Both could mean back, but using them at the same place are
misleading, puts an extra cognitive effort on the users to figure it out which one to
use (because it’s not obvious which one does what).
The problem that the “x” clears the whole search, but I’m 1 level deeper then the search (the card details window is a popup, so closing it shouldn’t clear the search).
Suggestion: use only one of them. Eithet the back button or the x. As a UX designer, I’d only use the x in the top right corner and it would only close the details window. Reason: Top right corner is more accessible on the phone, users are more used to it to find the close button on the top right and the action in one window should only have an effect on that screen (closing the details), not on another screen (search results).
