Transfer very slow (copy/paste) on my J3 :(

[snayk]

Hi everybody,

Since I have my J3, when I copy my music and paste in my J3's Music folder, it's very slow! About : less than 1mo/s like hmm 350ko/s

And it's the same problem when I delete songs

I hope someone could help me :/

I have a J3 16go (without SD card) firmware 2.23 (not the last one just before)

Thanks
