is this expected behaviour or a bug?
when i'm viewing any screen with the A-Z selection options on-screen, if i select any letter it correctly jumps to the content starting with that letter.
however you are then locked to that letter in terms of scrolling back up, ie you cannot scroll back up to the top of the screen. you can scroll down to the end, but scrolling backup beyond the letter you selected is not possible.
this seems like a strange UI decision as to get back out of that letter selection you have to select #.
i would have expected that no matter what letter you choose that full scrolling would still be possible.
