After the last updated the scroll bar just stopped working on Android phones, it stays hidden on the side which is a pain to move to a specific letter index, you just can't! Also the search/short is so much on the top that if you are on Z letter it's easier to close the app and open again than scrolling all way through the top, again since the scroll stopped working. You could at least give the option to the user to choose the old layout, the UI is so messed up right now... Hope you fix this.
