They are too focused on X5 3GEN. firmware !!!  

Same issue for me, this function is useless and permanently turned off.Hope in a short time serious updating!!

Same think for me.X1 II go too slow and bluetooth turn on in 10 sec while smartphone turn on in 1 sec !! X1 first gen. is perfect !!

Both embedded and external cover whit mp3tag for mp3 and flac file.Resolution and format cover are various.Whit x1 first gen.cover are perfect !

It is still unable to solve the problem of the cover display. All the problems that this update was to fix I've never had them !! I hope you manage to get a firmware such as the X1 first generation that's perfect !!

I tried to change sd card and now the flac files show the cover of the previous file !! I did reset the library and factory reset but nothing !! I inserted the card in the first generation x1 and all is well

The wheel speed can be adjusted in the future ? It's too fast !!

The cover is not embedded but added whit program mp3tagpro.The same card and file in fiio X1 show cover but in fiio X1 II not.

Cover display switch is on,firmware 1.4.1.Only on flac file whit cover album added with program don't show,mp3 file cover album show regular.

Why, when I pass the card from my fiio x1 to x1 II this one does not show the album cover?

No,theres no audio with only headphones plugged and bluetooth off

I try everything but don't work whit other headphones,only bluetooth !

I have problem whit my X1 II.With no reason do not hear audio whit headphones plugged in but only whit bluetooth.Somebody can help me ?

Done ! For first connect bluethooth device and then remote contol rm1 !!

I know,but x1 don't control remote rm1 and other bluetooth device like wireless earphone at the same time !
