I am using a UE55JU6400 model, already late to the party and the TV is on latest firmware something 15xx. Youtube now doesn't play 4k videos, don't know if it is youtube's fault or samsung. 4k60fps videos never played even before in youtube app, instead 4k24fps versions were played for videos which were 4k60fps before. TV performance is slowly getting crippled I think
Need to root and install old or any custom firmware badly.
