    Welcome to Android Central! Unmount the card in Settings>Storage, remove it, and insert it into your computer's SD reader. Run chkdsk to see if there are any bad sectors: http://forums.androidcentral.com/amb...d-sd-card.html.

    Sandisk is generally pretty reliable--where did you buy yours, and how old is it? If you bought it online from an independent seller, it might be counterfeit--run SD Insight to check. If it's several years old, it might just be failing due to normal wear and tear--SD cards don't last forever.

    If you got the card from a reputable seller and it isn't very old, you might consider contacting Sandisk and seeing if they can replace it.

    You may have a bad micro SD card, do a google search on it and you'll find lots of cases, it seems there was a bad batch of the 64gb cards when they first cam out specific to the Scandisk 64gb ones. I also had one for my S3 that did that, I sent it to Scandisk and they replaced it for me free of charge. Hope that helps.

    I purchased mine about that same time. You should have better luck with a new one. Why not hit them up and get it replaced especially if they will do it for free.

    I bought it from eBay though.....I don't think if I contact the seller that I bought it from, that he would send me a new one......

    I am having the same issue but it still looks like the Micro sd is working. I used this sd Card in my GNote3 before bringing it over to my GNote4. Never had an issue with it in my GNote3.. I am Upgrading to the 128GB Microsd.

    Get a MicroCenter card. They are cheap and very reliable. We use them in all the GoPro cameras in our drone program. I have never had one fail in my phones and my friends phones. Just waiting for a 128 GB version to come out. Based on current pricing, theirs should be around $69.

    Most cards are from the same supplier. You are paying for packaging and advertising on name brand chips.

    I turned off my phone took out my SanDisk 64GB put it back in. For safe measure I pulled the battery put it back in put on the back turned it on and so far so good no more Unmounting message while saving to my SD card.

    FWIW, I had all kinds of problems with many different "brand-name" SD cards with my Note 3. I bought a Samsung-branded card and it's worked great (my wife now has that phone). I have a Samsung-branded SD for my Note 4 and so-far-so-good.

    Not sure why the Samsung branded cards seem to work better, but others have commented on this as well.

    Hate being a pain in the *** and I appreciate the help.....so I think I'll get the 64gb Samsung PRO.... I read in a different thread that you can't put a 128GB in a Note 4.... Any idea if I can,cause if I can,ill get that instead of the 64gb,unless I can't go that big.....

    You getting bad info!! .

    You can bang a 128gb in the Note 3, so you know it will fly in the Note 4..

    BTW, I never had any problems with 2 Sandisk Ultra 64gb micro sd cards in my Note 3, and my Note 10.1 2014.. I always FORMAT the sd card in the device I am using it in, and I never turn it off when I am doing a write to the sd card..Never a problem.

    Now, I have a Note 4, and I am pushing a Sandisk Ultra 128gb Class 10, it hasn't blinked. I took the Sandisk 64gb Ultra and put that in my Tab Pro 8.4, and it works like a charm..

    I got a zillion movies, music and pics on my Note 4, and still got mucho space left.. However, for the price, right now, the 64gb Class 10s are the best bargains out there.. I got a PNY 64gb Class 10 for my wife S4, for $24 free shipping.. Can't beat that with a stick..

    128gb microSDXC most definitely works on the note 4. I am using one now
