https://community.sony.si/t5/xperia-archive/problem-walkman-lockscreen-z1-compact/m-p/3241454#M391433 Sorry for my english. Walkman and Vkontakte player work normal at 4.3. I can change music or pause/play it on lockscreen. Problem appear after 4.4.2 <A href="https://www.youtube.com/watch?v=y2KOqFwjAY0" target="_blank" rel="nofollow noopener noreferrer">https://www.youtube.com/watch?v=y2KOqFwjAY0</A> - you can see how it works now. I meet someone who have z1 compact with the same firmware like my z1 compact and there is no problem. I've rolled back walkman to first version - no results. Update walkman to the last version - no results. Delete Vkontakte - no results. But I don't want reset phone to default. Maybe may there is another solution.
