I have an e140 mp3 player, the firmware version is 2.0.001a.
I usually set the shuffle mode on, but it it does not shuffle very well the files. Once you have a set of files recorded in the memory, any time you turn the device on the playback always start from the same song. Besides, it repeats some songs a lot, and others are played very rarely.
Only if you add or delete some files, it changes the first song to be played.
It could be solved just with a firmware update, probably. Is my device firmware the latest or is there a newer one?
