I have bought an 128gb sd sandisk class 10 for the s7 edge but it recently has been having issues. It just randomly started to say sd unrecognized and wouldn't read my sd card even though it was working hours before it. I do 4 restarts and it goes back to normal with nothing deleted on it, but this is troublesome. Anyone else have this issue?

Ill post an image if it happens again.

Have you tried to reformat it? When you insert it, it should ask you if you want to reformat. That might help make it compatible with the phone.

Formatted when I got it, it does display that but it has 60gbs of information on it. Shouldn't have to do it more then the one time I wouldn't hope :/

Are you better to format the card on a computer first or better to format it in the actual phone first?

If it's a SanDisk card, go to SanDisk microSD Tech Support and you'll see 'live chat' in the upper right corner. Talk to them. If it's a known problem, they'll tell you how to fix it (or at least to prevent it in the future). If it's not a known problem, they may ask you to send them the card so that they can determine the problem. They're really nice people to work with.

If it's anyone else's card, contact the manufacturer and see what they'll do for you. El Cheapo Cards will probably lose the ability to speak English, Companies like Samsung probably will eventually help, but it'll take you a while to get through the telephone jungle to someone who can help.

(When Samsung messed up an update to the S3 that messed up the data on SD cards, they eventually fixed the bug - long after SanDisk had modified their cards to work around Samsung's bug.)

Thanks Rukbat, I'll try that out because it was a SanDisk.

Sandisk and Samsung phones don't play very well. I've had SanDisk cards go bad in my previous Samsung phones. Google it and you'll see.

Also, if you bought the card online, where did you buy it? Lots of counterfeit cards are sold daily.

Use an app called SD Insight to check if its legit.

I got it on Amazon and it's a legit one. I had SanDisk get corrupted in my Note 4 just figured they would have figured out something better on this phone lol
