With both firmware 3.0 and 3.1 my auto off timer no longer works. It's set for 10 minutes and hours later it's still on. I'm currently using the modified 3.0 so I can have the bolder fonts. Why would they go with tiny and hair thin? Also, I went to take the M2s out of my bag and the wheel had fallen off. I was very hesitant to buy this in the first place because I saw that as a problem. Fortunately I was able force it back on. I can't say if it feels the same as before, because it isn't the sort of thing you pay attention to until it's too late. I have a couple 128GB cards that I use with it. One for single artist albums, the other for various artists. They are all Flacs. I've tried playing MP3's on it, but there is a perceptible gap between songs that has been there with every firmware since I got it with 1.2. Gapless playback works flawlessly with both Flacs and OGG Vorbis q10. Those are the only file types that I've tried. I do notice, however, that it cuts off the very smallest part of the first song, regardless of file format, and there is a very distinct click after the last song with every firmware I've tried. Also with firmware 3.x, when the screen is off I can hit the Play/Pause button and it will pause, like it's supposed to do, but when I hit the button again a minute or so later, it won't start playing again. I have to push the power button to turn the screen back on and THEN hit the button to un-pause it. Over all I like the sound of this, but I wouldn't get another one without a touch screen, or at least some kind of wheel guard and firmware that didn't have so many little problems. I'm thinking I'll go back to my Rockboxed iBasso DX50 for a while. The sound is a little brighter than I would like, but that thing plays like a dream. And I can always adjust the equalizer a little to get a smoother mid/upper bass.
Update: Installing the modified 2.2 firmware fixed the problem with the player not turning off.
