I bought a new 16GB Class 10 micro-SDHC card and put it in my phone. Every time I lock my phone and unlock it, I get a notification message that the "SD Card was unexpectedly removed" and then it says "Preparing SD Card...". The card appears readable after that. I tried reformatting the card on the phone but it hasn't fixed the issue. Is anyone else seeing this? Suggestions to fix it are much appreciated!
Not sure if this will help but it can't hurt. I'd try formatting the card with SDFormatter which I'll link below. It could be that it needs to be formatted properly. Sounds like it's more a hardware issue though from what you're saying but again, doesn't hurt to try.
SDFormatter - https://www.sdcard.org/downloads/formatter_3/
What brand card is it. Some companies have big time inconsistencies throughout. It might be a bad card.

It is the AmazonBasics 16 GB microSDHC Class 10 Flash Memory Card.
I tried putting the card into a friend's AT&T Galaxy S2 and he gets the same error. Then I had another friend who has a Sprint Galaxy S2 try it and this time no error messages. Strange that this card has issues only on the AT&T version...
I will try the formatting using the sdcard.org tool later today.
I have the same card and I have no issues.

Cheap class10 cards are notorious for flakiness and compatibility issues...
I returned the card and bought a new 32GB PNY Class 10 card and that works just fine. Thanks for all the ideas!
Using this same card with no issues.
Is anyone else having the issue where the SD Card randomly unmounts itself and then remounts? I have already wiped and reformatted the card with the Note2 but the issue is still present. any solutions or answers?
I have the Tmobile version, but I have the same issue. I even did a full format of the card on my pc, but it made no difference. The card sort of works, but sometimes instead of the 'preparing sd card' I get the 'blank or unrecognized file system', and then I have to wait for the phone to go to sleep. It will usually wake up and recognize the card then, but all links to files on the card are broken. FYI, my card is a SanDisk 32GB Class 4. I tried an older 8GB card and did not have the issue, but then again, my 32GB card worked for a month with no issues. Very perplexed.

I have a Sandisk Ultra 32GB card. I only have music on it which I've only tested out a couple times, but never had this issue pop up at any point. Perhaps it is the format of the card? I do not remember reformatting mine before putting stuff on it. If you can, try testing another card or putting yours in another device to see if it's the card itself.
I had a 32GB Class 6 Sandisk Ultra, which was also used and worked perfectly in my GS3.
I went to my verizon store had my phone replaced.. threw the SD card back in, and it still had the issue. Put a normal 16 GB SD card in it, haven't had the issue yet. So I guess somewhere in the process of switching between my GS3 and the Note2 the card somehow got corrupted or broke??
Looks like I'll be buying a 64GB class 10 card soon lol

Okay so awhile back I posted a help thread asking why my 64gb class 10 sandisk microsd card kept dismounting / remounting. Ended up that the card wouldn't read in my phone at all but it would on my computer. I called sandisk and they said it was a Samsung problem (it's not). The Samsung representative told me that sandisk was fully aware that their 32gb / 64gb class 10 cards were malfunctioning on Galaxy S4's causing SD cards to fail, sd readers to fry, and even in extreme cases causing dead batteries/frying your phone. She gave me a direct number for sandisk that directly dealt with this issue and they will replace your card (they have limited life time warranties regardless). The new cards are fixed as it was only a certain batch of cards but if you ever had a random dismount problem or it's a reoccurring problem call sandisk to get your card replaced. Don't believe me, call bs as it wasn't a news worthy droid life or bgr post, I don't care I'm just sharing info that a Samsung representative told me and it may save someone's battery or even worse phone.

Ugh. My wife has intermittent dismount issues. PM me the number?
This was actually brought up a while ago. Your TLDR is misleading. A while ago sandisk produced a whole lot of 64GB cards prone to failure. Its not that this isn't news worthy, it is just old news. Of course it takes time for stock to clear, and you got one of the bad ones.
I still recommend Samsung UHS over a c10 sanfisk though

I hate you all for not having this post on the front page where I could've seen it before I replaced mine lol
One day it dismounted, and I didn't think anything of it. went to use it and it wouldn't work in my phone, so I put it in the computer, and it still wouldn't work. I just assumed it died on me, but maybe it has something to do with this issue. Any chance I could get that number as well? Maybe I can get another, or send this one back and get a replacement or something. It's not the money, it's just the principal of the situation.

Confirmed.
I went through 3 Sandisk class 10 64GB cards. They start to mount and dismount, it gradually gets worse then one day they dismount and don't come back. Can't even read them in an external reader on a PC.
When my 3rd one started doing it I just gave up and ordered a Samsung 64GB card which works perfectly. Gave the Sandisk to the wife to use in her S3, works great there.
My wife's GS4 was doing the mounting/dismounting thing with my old 32 GB SanDisk Ultra (class 10) card that worked fine in my Note 2 for a few months before I upgraded to a 64GB card, so I gave her my 32GB card. I kept it in the phone, but just manually dismounted it so she wouldn't see it anymore (good thing I got her a 32GB GS4 so she had plenty of internal storage too), but it would still occasionally freak out when she let the phone die and then booted it back up. But I just installed the 4.3 OTA update today and it seems to be functioning fine now. I haven't seen it spontaneously dismount the card at all in the past few hours and I was able to use it to store pics on from the camera. So maybe this was an issue with the GS4 and not the SD card? Like I said; it worked perfectly in my Note 2 for a few months and I tested/formatted it on my PC several times to ensure it was a good card, but her phone still freaked out with it consistently before the last update. Its only been a few hours so far though, so it could very well start wigging out again, but I'll definitely post back if it does. Also, her GS4 worked fine with some old 16GB cards that we had from previous phones too, so it seems that both the phone and the card were at fault somehow.
This happens to me all the time (I have the 32GB ultra lass 10), every time I unlock my phone it has a notification saying the SD card has been removed or improperly unmounted. I' on 4.3 and it didn't solve the issue.
I hope it's an issue with the card and not the phone, I wouldn't be able to get a replacement since rooting left me on custom status...

its the card.. it does that when they start going bad and eventually will not mount in computer either. I always keep spares around.. with 4 phones and 2 tablets.. at least one per year goes bad.
i had a the sandisk 64gb card you are talking about and it fried after about a month. sandisk was cool about it and sent me a replacement card pretty quickly. i haven't had issues with the replacement card yet.....
I think you all should knkw that the nonhlos modem files are causing this behavior. I just tried upgrading from mdk to mj7 nonhlos file and this exact behavior occured. I confirmed by going back to the mdk nonhlos and everything is fine. This is with a sandisk 64gb

hi guys me and the mrs both got Samsung s3 and with bought both 32 & 64gb micro cards to load music onto but though the music does load with in days the phone says the card is corrupt and needs formatting and so we lose all our loaded music and have to reload it all again, this is happening every few weeks or so and now becoming a real pain.
we bought the cards of ebay and are just cheap branded cards we have tried around 4 different cards now and all do the same.
do you think it may be that its just cheap cards or has anyone else had this problem of losing all the data on there cards on Samsung phones?
was thinking of buying Kingston cards but they cost loads and don't want to pay that sort of cash out if there not going to work either
any advice would be great
Thanks

Easy way to check is if the phone say's it is corrupt and needs formatting don't format it take it out plug into your pc with a sd card adapter and check the contents.If you can read and play the contents then it is the phone software that is the problem if not the cards are at fault and it would probably be a wise investment to get a better card.
Cheap sd cards on ebay are usually fakes, much smaller cards rigged to read what is printed on them.
You can download a tool on your pc to check the real capacity.
I have a 64gb class 10 Kingston sd card.
Sometimes I get an sd card error.
It can work for days without errors or I get an error per day.
After rebooting my phone the sd card works again.
Is there something wrong with the sd card or the phone?

ive had the same problem to a point it corrupted my sd card
honor knows its a bug yet refuse to notice it
will guess your on marshmallow?
Before i updated to MM i had a 32gb class 10 and had no problem with it. Upgraded to MM to find that it would constantly reject my card stating that it is corrupt even after various formats and even a factory reset. Replaced it with a 64gb card of the same make and speed and never had a problem so far. I placed the 32gb card in my tesco hudl tablet and its never caused a problem so far. I'm guessing the phone was just being a bit picky with what card i used.
Which brand sd card are you using now?
And yes, using MM.

Stick to Samsung or SanDisk. Don't want any other brand and never had a single problem with any (many) device.
