Re: Kingstone sdcard unsupported into my note 4

I had a similar problem with a Kingston 16gb class 4 card. I had it 18 months on a Galaxy S2.
It started to say it was unmounting, then remounted.

You may have a failing, faulty or fake card. Don't save anything precious on it.
Stick to Samsung or SanDisk cards. I now don't use any card on my 32gb Samsung Note 3. With smaller capacity phones they are essential, of course.
