Two of my three J1's updated smoothly. Today I noticed that the one I use for listening music (original media player) did not find anything to play. I have around 12 GB of flac-files on 200GB sdcard (ext4). Checked with file browser, the files were there. Tried even opening one with the file browser and it woke the media player. So far so good. But it was plying list of one song. So I thought that indexing was issue and wiped the index with the auxiliary settings application. Didn't work. rebooted phone, no help. Reinstalled player. No change. A new reboot and then presto, player found my music files.

Now there is one J1 to go, and Xperia X. I have negletted the Sony, but I guess I need to spend some quality time with it too.
