My experience concerns the last two Updates of Opera for Android (used with Android 4.1.2 on Galaxy Note N7000): some weeks ago I made 4 Bookmarks with Opera on my Homescreen. After each of the last updates Name and Picture of these bookmarks were chanced in "Opera" with the red "O". The bookmarks lead to the wished pages but cannot be distinguished anymore. This is anoying for me. I always had to renew the bookmarks.
