Search icon changes its position every damn time this app starts. Take a look at your picture number 4 and 3. At startup  search icon is near the upper right corner. Then after a second it is near the center top. When I open this app  most of the time I will have to search the article I want read. But when I hit the search icon  I usually end up clicking the star icon because suddenly it is now occupying the previous search icon position.
