Do we have to do a factory reset everytime we update a newer version of software? And if we do,do we transfer all our songs elsewhere before doing a reset? Currently I'm using the 1.1.7 version,felt that the SQ is wonderful already... Is it better to upgrade to version 1.2.3 from the previous version?
IMO no. It messes up the sound. Distored bass, boosted treble and mids in 1.2.3. But to get some benefits of 1.2.3 (if you have album art imbedded into your tags) you can update to 1.2.3. Then do a factory reset. Then let the player fully load up. Then play all music/albums from the main player tabs. Then revert back to 1.1.7 and have all your tags show up without downloading extra stuff and keep the great sound quality. I also like 1.2.3 wallpaper better (looks more luxurious).
