Otherwise, everything is already said, but not yet by any ;-)
Must now also make conclusion, my phone rings.
Update 9.3.15
One star less because with Adroid 4.4.x deleting and moving files no longer works from the memory card with any app. Is not attributable to Samsung - located on Google - but still more than annoying. I just hope that the S4 mini still participates in the update to 5.0.
