FWIW I have much the same syncing issues with the Sony Xperia S LT26i Android ver 4.1.2
MC18.0.211
Using device internal memory (no SD card option on Xperia S)
Syncing 1,211 files in 41 playlists using default paths and re-encode set for incompatible and high bit rate files
Log file attached was with Xperia in SB debugging mode, however results don't seem to be any different out of debugging mode.
Specifically;
- Upon plugging in the device MC shows in the Action pane "Device is fully synchronized" (it is not), while the pane under the Device tab shows "Working..." After around 30 mins (Resource monitor shows MC Av CPU 1.4%) before the display populates with the device contents
- Shows 41 items (no apparent exclusive distinction) In Queue to be synched even though they are already on the device and have not changed
- On synch shows Uploading: 100% then Error in status, yet the track is there on the device
- Playlist pla files copied to device, but empty with 0 byte size
In another issue;
When synching a large number of files for the first time, with many requiring re-encoding, set file path for music is not honored and most files are transferred to the root of the device.
I'm thinking to adopt this work around until there is a fix
