I had a strange problem happen to my SD Card on my SG3. I have a Patriot 16GB class 10 card that I used on my EVO 4G for a almost 2 year without a problem. After when I got my new phone I clean all folders that I no longer needed except my pictures and some applications. Put the card in my SG3 and everything was OK. I was able to copy files take a pictures and everything seems to work the way it should. Last week I was on a trip and during the process to taking a picture I got a message that my card was removed and basically disappear. I reboot the phone and nothing happen. then a little bit later I saw another message that card was found and everything show up again. Then I check do I have all the pictures and most of them were there except on a last one was (when card disappear) basically it was look like that picture was taken a half way. So I delete that bad picture and continue. A day later it happen again but this time when card show up again instead a normal card I have that message in notification bar with a little sd card that it says Blank SD card. then if I pull down and click on it phone is asking me to format the card. I try to mount the card but got the same message Blank card or unsupported file system. Ok so I didn't have at that time my adapter to plug in to my laptop and wait until I got home to try to repair the card.
Here is what I got now and I'm not sure is phone damage the card or card slot on the phone is not good.
I use minitool under windows and GParted as well under linux. Both of them recognize my card as 60 GB Unallocated space (it is a 16GB). when I try to recreate or format both of them said successful but card is not show up. I have to plug it back and then it goes again as a 60GB unallocated space.
Does any one know how to format a 16GB card as FAT32? I mean the settings I have to use to put to get back again this card as a 16GB not as 60GB.
Sorry for the long explanation and thanks for you help in advance.
P.S. I' not rooted and on LG8 update.
Bro,did to trid any other sd?

Windows will format it just fine under Disk Management. The fact that its reading it as a 60GB... I'd bet on the card as bad. I have hours and hours trying to save thumb drives and SD cards. 97% of them had no hope. Sometimes the card reader can act up... but not likely, and the phone's kicking it out too. Try to stick with Kingston or SanDisk even if you have to pay a little more. Yes, Cards do go bad like that.

Thanks for the reply. It is look like that this card is going bad. It kind a surprise me since I didn't have any problems under my old phone. I will play a little bit more to try to repair it but....... looks like will be a lost a time.
Do you think that because it was a class 10 card causing a issue? I saw a couple treads but most of the SD card that people use are class 4.

Probably 1.5 year. I got my EVO 4G back in sept. 2010 and bought the card a couple months later when rooted my phone.
Yeah, like root said, the class wasn't the issue. The different phone might have pissed it off but you really never know. I never liked Patriot myself, but then some people like them. Gotta back stuff up or have it auto upload somewhere.

last week suddenly received a message that the card was blank. did everything i could not to format it. finally gave in and tried formatting the sd card but couldn't. had to buy a new one. sounds like yours is going bad as well.

When I first got my SGS3 I used my old card from my OG Droid. I got an OTA update and my phone quit working (I got the "Unfortunately the process com.android.phone has stopped working" message). I took the phone back and they asked if I had ever had an SD card in it. I said "Yes, my old card from my Droid." I was told that this is a "known issue" with the SGS3 and that any SD card I used should be formatted in the phone itself. I'm not sure if this is the issue here, but it might be.

P.S. I did play with couple more tools but unfortunately no luck at all. It is time to look for a new one.
I have a Bell Note 2 and I recently bought the 64GB SanDisk Ultra microSDXC UHS-I card. Since using it, I noticed that (when installed) the Device Status of the phone changes to Modified and I can't check/download Android updates from Samsung. Also, the Samsung Video Hub app won't let me use external storage to save movies (which I could do using my old 32GB PNY card). The card seems to read/write okay though.
I contacted Samsung by email, the reply was laughable (solution was for a different issue on a different phone). I also contacted SanDisk and they suggested reformatting to FAT32 using a utility from www.sdcard.org. I haven't tried this yet but I know that FAT32 will reduce file sizes to 4GB. I don't know if it will have an effect on the read/write speeds of the card.
Just wondering if anyone else using this card was experiencing the same issues. If you haven't checked, maybe you might want to.
I miss the build quality, sleekness, and how quick the battery would charge/how slow it would drain.

Well, I tried to do what the SanDisk guy told me but the formatting utility that he mentioned doesn't have the option to change file formats. Started out as exFat, still exFat. Some of you have mentioned using other formatting/partitioning utilities - the folks at www.sdcard.org say the following:
"The SD Formatter was created specifically for memory cards using the SD/SDHC/SDXC standards. It is strongly recommended to use the SD Formatter instead of formatting utilities provided with operating systems that format various types of storage media. Using generic formatting utilities may result in less than optimal performance for your memory cards.
The SD/SDHC/SDXC memory cards have a "Protected Area" on the card for the SD standard's security function. The SD Formatter does not format the "Protected Area". Please use appropriate application software or SD-compatible device that provides SD security function to format the "Protected Area" in the memory card."
So there you go.
I am using the card with the t-Mobile version and it working fine.

Works without any problems in mine.
The weird thing is that it starts out okay and only shows up after I've reloaded all my apps. Even then, I can still read and write to the card. I just can't get updates because it says that my phone is modified. I can't see how an app would cause it. There are no side-loaded apps. And it doesn't happen with my 32GB card.
Just a quick update for anyone who might be wondering....
After making this thread, I went to my local BestBuy and bought another SanDisk microSDXC that was exactly the same as the one I had. I put the same files on the card and the phone did exactly the same thing. I did discover however that the problem shows up when I reboot the phone with the card installed but doesn't show up (at least not right away) when I unmount/hotswap/remount the card with the phone left on.
Then I took the card to the BellAliant store where I bought the phone and had them try the card in a brand new phone. Same problem on the new phone.
Nothing funky on the card, just my songs (transferred using DoubleTwist AirSync) and my photos (transferred via PC). This card hasn't been reformatted and my phone hasn't been rooted.
So I don't know what's going on, if its only a problem with Galaxy Note 2's that are being sold in this area. I can't believe that no one else is having this issue.
Anyway, I put in a support ticket with Samsung (again), not expecting anything new. The Samsung tech that I spoke with did say that only TWO (I think) 64GB microSDXC cards were tested and approved for the Note 2 and that the SanDisk was one of them. Also, the girl at the BellAliant store said that they were told that the phone only worked with a TOTAL of 64GB (internal + external) but I KNOW she was wrong about that. Just some of the things you hear when trying to troubleshoot something that no one seems to have an answer for....
iMHO you really should format it fat32 and retest.
-- other suggestions for tools --
Might search for mini partition tool or gparted live cd. I've used the gparted live cd to partition my 64gb sandisk previously for dual booting my og atrix.
-- I'm sure there are better suggestions on tools, but I strongly suggest converting it to fat32 before further testing / actions.
The Note II ONLY supports FAT32
When I got my new 64GB SanDisk card I powered off the phone. Pulled the back cover and replaced my 32Gb with the new 64GB micro SD card right out of the packaging and then replaced the cover and powered it up. Phone recognized it and accepted file transfers to it without issue. No problems to date and I have been using it for 3 weeks without issue.
ExFAT works fine with my note 2 on perseus. Doesn't play well with note2core though

If the Note II only supports fat32, then someone needs to tell my note because it's working fine with my card on exfat. stock kernel and all.
I too have bell note 2 with 64gb sandisk and everything is fine. I jusy put the card in the phone and formated with phone. Its exfat btw.
I suggest u to format the card with phone so it can format with the appropriate fike system.

See, that's the strange thing. The card DOES "work" - it formats fine and I can transfer files to and from it. The ONLY problem is that, when I put my files on it, the status of my phone changes to "modified". Then, when I go to updates, it won't even try to connect to the servers, just tells me that my phone is modified and that updates are not available. As I mentioned above, I've duplicated the problem with two identical cards and in two different phones (one of which was in-store, brand new).
I realize that I can just take the card out of the phone when I know an Android update is available to download, I just don't always know when updates are available. In either case, doesn't seem like it should act that way. And I didn't want to force-format the card to FAT32 with a 3rd party format utility because that would destroy the "protected partition" on the card and void the warranty (those 64GB cards are expensive).
I understand that I might just have to live with this, it's just odd that no one else is experiencing it. Think I'm going to let this thread die. Folks on XDA tend to not like re-reading the same thing over and over. Thanks to all who replied.

Why do you think formating an sd card with fat32 would void the warranty? Never heard such thing before. You can format any file system you want.
here's a real puzzler. Today I noticed that my SD card wasn't mounting anymore. I'm rooted on stock ROM. Everything else seems to be working. It won't mount. I've tried using root Explorer and TWRP. Nothing. Thoughts? Anyone?! TWRP sees the card while I'm in recovery. Once I reboot into stock ROM, I lose it. I try to mount it, then I'm getting a 'safe to remove card' notification.

Stupid question, but have you tried physically re-seating the card? I had odd issues like that on my S2.
Other thought, can you mount the card using a PC?
I've tried reseating the card multiple times with no luck. TWRP will see the card while in recovery. But when I boot into the OS, I lose it. I'm stumped.

One random thought, and probably isn't your solution ... Is the card formatted with exFAT or ntfs. Gs4 won't natively support ntfs formatted cards. Plug it into ur pc and check the properties... Worth a shot

If this was the problem would it cause all sd cards to unmount? Or could it just effect 1?
I have a 32gb card that unmounts and remounts randomly. My 16gb card doesn't seem to have the problem.
Im not sure if the 32gb card is faulty or if it has a correctable error. So far formatting it does not help.
The difference between me and the op is that my card will mount, it will just unmount itself at a random later time.

Have you by any chance flashed a different kernel? I believe ExFAT file system is closed source and is not supported by most custom kernels, even if you're still running the stock ROM. If not, can you think of anything that you've changed between the last time you remember your card mounting and now?
Same here, plus viewing media on the card in the gallery seemed really laggy. I switched to a 16gb and have had no lag or issues with the card being mounted. The cards I got are both SanDisk Ultra cards

Back to exFat, formatted with PC, Mac back to fat, either AOKP, or touchwiz. Same issue. At first it was fine. Then slowly started dismounting and remounting. Then refused to mount...worked around the issue by formatting in exFat, mounting in TWRP.and reformatting... This seemed to fix it for about an hour, I started downloading my music from Spotify...again with dismounting... Drove me crazy...ordered Samsung 64gb

Yes, as a matter of fact. Look up at the link I posted above. Turns out it has to do with rooting and needing to flash a SetUID kernel prior to flashing Super SU. Something in there about exFAT not working. Flashed the exFAT fix and I'm up and running! :thumbup:

My phone is completely stock and unrooted. It's an SGH-M919. I've had it for less than a week.
I too am having an issue with the SD card. I bought a brand new 32gb PNY card, class 10. At first it mounted fine and there was no problem. I transferred files to it from my old 16gb card that was in my Sensation for 2 years.
The following morning, after the phone slept and charged for the night, the card unmounted itself. There was an error message in the notification bar. I tried repeatedly to remount the card to no avail. I reinserted it a dozen times, rebooted the phone several times with pulling the battery, but the card wouldn't mount. I then tried the card in my wife's brand new S4 (we got both phones the same day) and the card didn't work in her phone either.
I then plugged the card into my laptop and it mounted just fine, and all data was still on it. I tried it in the phone again, but it didn't mount yet again. I even reformatted the card in my laptop, but it still didn't work in either of our 2 S4's.
I went back to Frys and exchanged the card for another PNY 32gb card. It mounted in the phone just fine, and again I transferred files to it. This morning, again after a night of charging the phone, the new card was unmounted with the same error message. However, when I woke the phone up, after a few minutes the card remounted itself without having to take it out and reinsert it.
So far it's been about 7 hours and the card has stayed mounted with no issues. We'll see what happens overnight again, when the phone is charging and sleeping.
On the other hand, my old 16gb card has stayed mounted in my wife's S4 with no problems for several days now.
Like the title says, picked up an SD card, doesn't show up under the Storage menu or when I connect to PC via USB. I've downloaded an app that lets me format the SD and it shows up there, but after formatting I still can't access or even see that the SD card in installed.
It's a GSKILL class 10 64gb SDXC
Hmmmm. Have you tried a different card to see if you get the same results? I'm using a Lexar 633x 64Gb card. No problems to report so far.

Hmmm, investigation with a torch and loupe revealed that one of the MicroSDXC reader pins were bent down.
Managed to lift it with a needle and now it works fine.
This was on a new phone, wonder if other people's problems had a similar cause ?
Format the SD Card in storage settings. It should format and be useable
Try couple things:
1. Try (may be borrow from a friend if you don't have one lying around) a different brand name card. Some generic brand cards (especially from eBay) are little flimsy and does not provide proper contacts. It happened to me on both HTC M8 and LG G3. Tried SanDisk card and all went well.
2. Try formatting the card using PC into Fat 32 format (you can always reverse this formatting to ex-fat) and see if this make any difference.
3. This one sounds very basic but under storage, sometime you have to manually click on "mount SD card".
Good luck!
Ok try this
1- but it in lapttop slot (card reader of laptop ) dont try another way .
2- use SDformatter 4 .
3- ok now put it in your device.
I hope it will work properly

I have this problem too. April 2017 and LG STILL haven't sorted it out. Impossible for so many owners to have faulty phones. Definitely a SOFTWARE issue ! Terrible customer service. I actually NEED to use an SD card in my work. .Never getting an LG phone again.

Have spoken to a repair shop and what they said is that this is a typical issue with the LG G3, another one (which I also see a lot) is spontaneous reboots, even when the phone is seemingly doing nothing. And these issues get only worse over time. The only way to solve them is to replace the mainboard, which probably isn't worth it. Looked at alibaba.com, they are around 30-40 USD. I have reflashed the stock firmware in my futile attempts to get both issues solved, but it is obviously a hardware issue.
Yeah stopped working too. I've noticed an issue with a pin in the MicroSD card slot. I imagine this is the issue. I'll open it up when I have time.
Take the card out, insert it in a PC and check it for errors. DiskGenius or MiniTool Partition Wizard can help you here. DiskGenius can also check for partition table errors.
Also make sure the card is formatted exFAT, not FAT32 or NTFS and that the cluster size is either 8K or 128K.
If that doesn't work back up your files, format as exFAT with 128K cluster size, then copy the files back. You may have to do this anyway if a partition table error is detected.
For the longest time, I have been unable to use my 128GB Sandisk MicroSD card properly with my GN4. I have tried SD card fixes, foldermount, and messed with the platform.xml file as well. What I used to do back in the days of ICS/Pre KitKat 4.4.4 was take the SD card and plug it into my computer (via SD card adapter) and transfer the files I needed directly since it takes a while longer if I connected the phone to the computer. I can still transfer files to the microSD card if I plug it in, but they are not able to be read. This is starting to piss me off as I have a lot of music that I would like to store on the card. Anyone have anything else they can suggest?
I used foldermount last week - Some of the music files work properly, while some don't play and I get the message "unable to play this file."
I bought this card brand new and I'm hoping it's not "a bad card"

I also use a 128gb Sandisk Card, the "ultra" I believe. I never had a problem with it, I just came from the Note 3 and put it in the Note 4 with no issues. Is yours the "Ultra" also?
Maybe a bad card. I got 3 fake ones on eBay before I got a real one. I flipped out on the sellers and reported them. Each time I got a bad one I spent hrs copying data over to the 128. I would copy over around 20 gb, and another 20 and so on. When I went to look at the files that I had first put on there they would be gone. There are programs u can download for free. Just Google how to tell if sd card is fake. A fake card is really a 2/4/8/16/32 card changed to look and act like a 128 and once it hits it's limit that u don't know what that is, the earlier data that was put on the card, disappears.
Here is a link for a program I used:

This happened to me back in Oct/Nov when note 4 was launched. I ended up paying $120 on eBay for SanDisk's highest r/w 128 gb card.
The first seller claimed he didn't know they were fake and promised to stop selling them if I retracted my bad feedback as it was the only bad feedback he had ever received. Once I saw they were removed from his selling list I retracted the feedback. The second and third sellers I was not nice to, did not even have to send them back the pos card. My response was something like refund my ****ing money now for selling me this fake ****ing sd card. Ten minutes later both had gave me my money back. Assholes. After I got a good one I had contacted the first seller again and explained how much trouble I had and the scam artists there are on eBay. I feel that he was genuinely sorry and had no idea. He also stopped doing business with who he was getting the fake cards.
This good card has been great, note 4 32 gb internal, 128 external, both full, zero problems.
Plug it into your computer and check if it's formatted correctly (fat32 vs NTFS). That might solve the problem. Don't quote me, but I think it needs fat32.

Yes it does need to be fat 32.
Also if is fake, u might format it, move data, insert in phone, and it says it's not readable and needs to be formatted.
Yes mine is the ultra version as well (in red letters on the micro sd card)

the two options are exFAT and NTFS. I formatted on exFAT and it seemed to be working just fine until today.
So I use my sd card as direct storage for when pictures are taken. I was at dinner today and took pictures of the food we ate. All of a sudden when I go to the Gallery, I see a black and grey image with an exclamation point for the pictures taken at dinner with the exception of one. I am wondering whether Samsung/Google is releasing updates that put the phone back into the main issue of not being able to R/W to the external sd card? I don't know what else could be the reason. I also tested the card to make sure it wasn't fake. SO DAMN FRUSTRATING!
Shouldn't have to format it. Already exfat when it comes. If it's real, contact sandisk with pictures of the card and it's serial number and a copy of the receipt. They will replace it.
