Thus microSD card worked fine for a year in my Samsumg Note II. I mostly used it to listed to downloaded music from Spotify. It has actually failed &#34;twice&#34;. When it failed the first time (the phone couldn't &#34;see&#34; that I had a card installed) I thought maybe something had merely corrupted it, so I formatted it, put it back in my phone, and re-downloaded all my playlists. It worked for two months and then failed again. I don't plan to try formatting it again, I'll switch to a different brand of card.
