So for the phone side, no complaints, it deserves 5/5
As against the side audio / video player, if you want to buy it, past your way
Already the audio library is worthy of Samsung players: you will have beautiful edit the tags of your MP3, sort the files using folder trees, the phone will always show you by ... alphabetically by title.
Moreover, it is a very bad play MP3 tags, and impossible to get out the songs of a singer or a particular group: 2 to 3 it will put the artist is unknown.
And no need to use the software supplied with the phone, "Kies", it does not allow to fix these problems, and also it has an unfortunate tendency to crash.
Finally, the best for last, impossible to put videos, even if the software can convert and redimmenssioner specifically for the telephone, both the video setting on the memory, the phone can not read them.
And there is also sometimes the same problem with the pictures, sometimes it does not play some photos, for unknown reason.
In conclusion, so for all the phone side, as I said above there is nothing to repprocher him, this device is really perfect, it does what it must, and does it well.
But cons for the player hand, if that's really what you want, better to take another phone.
