Thanks for sharing.

You forgot to disclose the manufacturer and model of the card. Havent had a problem with any micro's in my v20.

It's a Samsung SDXC
$oul€$$ D€m0n!

Im having issues with sd card with camera saving to sd card. Also when i crop a photo it won't save. Using my 256 card from my Note 7 that cane with phone. Never had a issue on the Note, with the V20 km.about to just use it for the DAC only n go back to Note 5. Permissions in Google have been charged to give permission but still cant saved edited photos

I recently had a Samsung sdxc evo class 10 fail (suddenly couldn't write anything despite having 80gb of free space left).
Did manage to copy the data off of the card but I ended up having to get a new card, this time I went with SanDisk class 10. So far so good.
Wonder if there is a defective batch going around (I purchased mine about a year ago)

I have the same card from Samsung,( it was free with the Note 7). Unfortunately, I'm still having problems playing videos. I've tried VLC and MX, but both only play some of the files from SD. Any suggestions would be greatly appreciated.

Definitely have to format. If you'll notice the card is assigned I don't know what to call it and filesystem may have been handled differently. I had to do same. Took time but works proper.

Same thing happened to me, 128gb card bought about a year ago. I had to buy a new one.
This new one has been "corrupted" twice now to where I had to format it.

Thanks for sharing. But none of those is related to my issue. My card isnt corrupted. My v20 just wint read it but when I put it back in the v10 all is fine also my computer reads it. But the v20 dosent even see external storage that is my issue

Sounds like it may be a hardware issue.

I believe you are right I just popped in a 8gb san disk I had brand new never used and phone doesn't ever register it. But as far as I know regardless of Sd card inserted ir not the phone should show external memory in the menu

Probably needs format on phone.

That is correct. The phone should detect it regardless of the need to format or not.

I solved this by moving the SIM from the main slot to the side slot (dual SIM model). Weird thing was that anything < 64 gig would read fine, larger SD cards wouldn't. Only thing i can think of is a design flaw whereby the SD card is getting pushed up and not making contact properly due to the SIM underneath it. Try taking the SIM out and seeing if it will read/format/re-read it then?

I have an ATT LG V20 that experienced the same symptom so I tried similar procedure by remove SIM card and insert the micro SD then boot up to see if it would first see the SD card and it did, after that I shutdown and reinsert the SIM card and everything is still working.

Problems when it comes to new 32gb micro sd card

ok so i got my 32gb mirco sd card in the mail about 4 days ago and nothing but problems cause my sd card is still BLANK.... I connect it to the computer and transfer all my music to my sd card in a folder called Music and in that folder i have all my artist then in album folders then lastly all the songs so yes i like my folders organized but heres where ive been having the issue i unmount the sd card and when its done scanning media files on sd card the music folder is all thats left and all artist album folders are gone along with music files ive been trying for 4 days and same out come ive reformated the sd loads of times and still no luck and the spec on the vibrant says it can handle 32gb card ive looked every where i can for an answer to this issue but no luck only thing i found was that someone was having the same issue on the htc Incredible and its getting really aggravating considering i spent $40 on the sd card which yes is a bargain compared to tmobiles $80+ for the sd card but still I want to know if anyone else has had this issue and or knows how to fix it right now i am currently doing another reformat of the card and with the quick format unchecked and its been going for like 20 minutes and looks about 5% done so far so if i have any luck with this I will let you all know when im done other then that if any one can help please do.....
Remember the phrase to good to be true? $ 40 for a 32 gb? You probably got ripped. Try formatting it for 16 8 4 2 or even 1 to see what you really got.

Don't trust what T-mo reps say. Most of the time when they can't answer your question they make up the most obvious answer. I'm sort of thinking that it is the card itself because if the phone didn't support it, you most likely would get an error.

all the card says on it is microSD HC 32GB nothing else but its labled the same way my 8gb card is and the 8gb works fine only thing is with 24gb total im out of memory already with all my music i want on it but tmobile says according to their user manuals the tmobile version supports up to 16GB
The phone supports Micro SDHC, which is a standard. The same way any old camera made before 512mb, 1gb, and 2gb cards even existed can support those sizes, so too can any phone that supports MicroSDHC support 32gb cards. I am almost 100% certain that it is not actually possible for the phone to not support a 32gb card. Any issues you are having are likely something else. I recall a similar problem with my 8gb miscro SDHC card in a sansa Clip+, it wouldn't copy more than a certain amount onto the card before windows would just stop and fail. It was just a software issue in how I set something up. You are likely running into a similar problem.
Did you format the card on the phone? If not, try that.
Sent from my SGH-T959 using XDA App
Not to be a downer, but $40 is quite a steal for a 32GB microSDHC card, as they are about $100 more than that. It is likely not a 32GB - Have you tested using a computer and formatting it and filling it up with say 32GB of data (music, videos, etc)?
I have a 32 Gb sandisk micro sd card that i put in my vibrant the first day I got it and haven't had a single issue with it. I didn't even have to format it. I just dropped it into the phone and transfered my music and movies an such to it no issues at all.

My 8 Gb drive, as formatted by the Vibrant, shows up as two logical drives when mounted on my computer via the USB cable. Is this the case for you? On my Windows computers, those happened to be assigned as the E: and F: drives. Your assingments may vary.
I noticed when I was copying the Movies folder containing Avatar to this card that I needed to copy it to the logical E: drive, which was otherwise empty. It did not work when I copied the folder to the subfolder called /sdcard on the logical F: drive. But other simple data files, copied to the root of F:, show up on the phone's SD card and are accessible.
So maybe media folders are treated special somehow? I don't fully understand. But if you do see two drives, you might try copying the Music folder to the other one.

I'm not sure what's going on in your particular case as far as what you can copy where, but the reason you have two volumes showing up is because you're seeing both the interal 16GB and the microSD card (which Avatar is on).
As stated above the vibrant definitely supports 32gb. Have you tried the card in another phone?

eh, I don't want to hate directly, but knowing the guy's luck it's probably a class 2 or something if it's that low on price.
kelmerp is correct as to the other reason - the guy is not looking at the right share. When the phone is mounted via usb, you will see 2 shares on your pc.

Umm... Class 2 is all that's out right now for 32GB as far as I know. And they're running upwards of $100 easy. The Sandisk one is the cheapest at $99 from Verizon.
I bought a 32g off of ebay and it was ~85 dollars and it works perfectly. I stuck it in the phone formatted and then transferred everything over. Sandisk.

Swapping out the MicroSD card of HTC Surround

Ok... I'm not so sure If i was supposed to make a new thread or reply to an old one... but If you replaced your MicroSD card, then what kind did you replace the 16gb card with? I put in an older 8GB C4 card and my phone is not working as well as before. It is not responding during sync and it opens applications a bit slower. Every time, after about 5 minutes into the sync operation, it stops responding and I have to reconnect it to my computer, and I fear that it is overcharging the battery.
So just curious, what brand, model (if you have it), size, and class, are you using currently?
SD Cards
Hi Kuree,
The first time I replaced my SD i used a Lexar 16GB Micro SDHC (it has a 4 in a cirlce on it as well). This one worked perfectly, syncing and there were no slow downs what so ever.
The card i have in my surround now is Also a 16GB MicroSDHC (with a 2 circled on it) this card also works perfectly. i'm not sure on the brand name as this one doesn't say it but I'm pretty sure it was a Lexar Mobile version.
I've only used 16GB cards so i can't exactly tell you if the 8GB card is the root of your issues.
Hopefully this helps you out!
If you have any more questions let me know and I'll see if i can answer them.
Take care,
Coockoo
problems....
I guys, sorry to resurrect an old thread. I'm having issues with upgrading to 32g... after hard resetting the phone and setting up time, the phone just gets stucked in "installing apps". It just seats there.
Any suggestions or things I should try??...
Any help will be highly appreciated...
thanks

Hi,
Is "ADATA" micro SDHC 4
They told me (were I bought this) that this card should work.
Now I can't even read or format the SD card....
Thanks!!

I didn't even know the surround had a memory card slot, where is it?
Any chance to revive the "adata" card?. I would really hate to trash 26 bucks...
To LKMR, search youtube, there is a nice tutorial on how to expand the memory of the phone.

I used a Sandisk Class 4 32GB. No problems at all... WELL worth the price and effort. They are also VERY cheap if you keep an eye on Deal a Day. I've bought 4 from there so far, the last was like $20.

S5 and SanDisk 64GB UHS-1 problems w/ camera

The first few photos went to the SD card then I get error messages saying...
http : // i807.photobucket.com/albums/yy360/sell90254/IMG_9360_zpse1bc05a4.jpg << this is the image but I'm too new to post pics.
"Unable to save file to SD card. Default storage has been changed to device memory."
So, I Googled around it it seems that this problem has popped up before but I haven't yet found a resolution.
I have the latest SanDisk 64GB UHS-1 microSD card. I thought that the problem last night was because I corrupted it by writing to it from my Windows 8 PC but I've since reformatted it with the fat32format.exe utility so that should be good.
Any advice?
I keep switching it back to the SD card but it worked for only a few hours.
My first Android device...
Maybe it's OK? Maybe my answer will help other NOOBs (like me)?
It seems that it depends on which shooting method that you use. And, I knew that because I read the entire manual while patiently waiting for what seemed like FOR-EVER for this thing to come out.
Anyway, I wasn't in one of the special "shot & more" modes so I thought it would be good but 'burst' somehow got checked and that was the problem.
:silly:
did you try formatting it?
it should work...i think its either a formatting issue or a problem with your card

YES. I did reformat the phone but learned a lot more about this.
--- THIS IS NOW A USEFUL POST ---
The problem is the version of this memory card and the exact part # and mislabeled packaging (can't post pics and URLs because I'm still too much of a NOOB to be allowed).
Here's what I wrote to the guy that I bought this from and he agreed to accept my return.
"I am so sorry to do this but the part # that you sent is different from the one you advertised and it therefore doesn't work in my Samsung Galaxy S5.
#1. The ad that I purchased from clearly said that I was buying a SDSDQUA-064G-A11A (Class 10 / UHS-1) but I instead received a SDSDQY-064G-U46A which is actually a class 6.
Regardless it is a different part #.
#2. This is documented on the SanDisk forum.
Question: Is "SDSDQY-064G-U46A" the same as "SDSDQUA-064G-A11A"?
From http://forums.sandisk.com/t5/Mobile...he-same-as-quot-SDSDQUA-064G-A11A/td-p/273971
Answer: SDSDQUA-064G-A11A is a class 10 UHS-I card in US packaging that has the android logo on it. SDSDQY-064G-U46A is a class 6 card in EU packaging #
3. I tried to use it because 64GB is 64GB but the phone requires a certain memory speed in order to support the camera and it automatically switches photos to the internal memory because the memory isn't class 10.
#4. I ran benchmark testing on my phone and confirmed the speed. The package is opened because I did try to use it but I've got all the material. Please let me know where I can send it back in order to receive a full refund."

Google for "SDSDQY-064G-U46A SDSDQUA-064G-A11A" and you will find other articles.
My solution was to buy the 'Extreme version", I know it's 2x the price but not being able to take certain types of photos or videos on my SD card is unacceptable.
Specifically...
SanDisk 64GB 64G Extreme micro SD microSDXC Card 45MB/s 300X UHS-I Class 10 +smal multifunction Case
I have seen this same complaint on forums at Amazon, eBay and NewEgg. All supplied the much slower card which I can confirm does not work in the S5.
PS Here's a picture of what I bought that says Class 10 / UHS-1 but isn't really...
Just make sure the part # ends in A11A because the one ending in U46A won't work properly in your phone.
I have the extreme plus version and it works great

Thanks.
I was pretty sure but that's EXACTLY what I wanted to know myself. I bought "extreme" and not "extreme plus" -- seems that there is a 2x difference here in speed. Hopefully the 'extreme is enough'. The lesser version of the "Ultra" (U46A) clearly is not.
I bought this one from http://www.rakuten.com/prod/sandisk-extreme-64gb-microsdhc-uhs-i-class-10-memory-card/256138497.html
and not this one from www.rakuten.com/prod/sandisk-extreme-plus-64-gb-microsdhc-class-10-uhs-i-memory-card-with/263090059.html
Some part #'s:
Extreme = SDSDQXL-064G-A46A
Extreme Plus = HK092 ???
Seems like most sites don't always list the full part # (example above) and many others list one but sell a different one like when I ordered the non-extreme version.

I've had a similar problem, it started in my S4 with the 64gb SanDisk but I thought that the camera had gone faulty! Upgraded this week to S5 and put the sd card in it and all the pictures I took were OK for a minute then went corrupt? Also noticed that I couldn't put apps on the sd so process of elimination brought me to the card. Turns out it had gone faulty but had a second one in my gopro so put it in the phone and all is working perfectly but the other card is dead and can't even format it. Not sure if this helps or similar to your experience but thought I'd share

I tried the Ultra and not Ultra-Plus. The Ultra worked for most things for me but not high speed cam/camera functions.
If you tried it please let me know.
From this point on I buy the Extreme Plus and never looked back.

SD card unexpectedly removed...?

SD card unexpectedly removed... The heck does that mean? I didn't take it out nor jar or drop the phone. That just popped up and I didn't have access to the SD card until I rebooted. It's a 128gb samsung evo microsd that was formatted in the X. Anyone else have this issue?

No issue here. Could be a sim tray or contact issue. 64 gb card forget which brand. Sandisk pro I think.
I'm having the same issue. Love this phone! But this is getting a little irritating
I have not had this issue. Been using the phone for two weeks with a 64 GB Samsung Pro+ card in it since day one.
I just boxed my turd up and sent it to moto today. The bootloader was unlocked but flashed back to stock unrooted, hoping for the best. They gave me a code to get a new one made...it said it will be here Oct 1st.

So, far I've only had it twice in the 3 weeks i had it
Like other folks stated, it has to do with the SD card. If you purchased a SD card from eBay or something generic, you are bound to have this issue. I think it has to do with the flimsiness of the plastic. Borrow a good brand card from someone and give it a try. Chances are issue will be resolved. I had the similar issue which was resolved by purchasing a genuine San Disk card.
It is not necessarily the card. I have a genuine 128GB Sandisk microSDXC (exFAT file system) that's very fast. After no problems for several days, the Pure gave me the message that the card had an incompatible file system and asked if I wanted to format it. I reset several times, got the same message twice, then after that the Pure didn't recognize that a card was even present. I pulled the card (and SIM!?) and reinserted it, and it works fine again. Only catch is that now all the files on the card have that day's date and the time I reinserted the card. Bizarre and very troubling. My plan is to format the card in the phone and reload it from the backup on my hard drive.
I had this problem for a while on my old Samsung GS3, and it turned out to be a firmware issue on the phone that Samsung never addressed. I hope that it's not the same case here.
same problem here. i use my old sd card for two or three weeks. this card works fine. its a 8gb sandisk micro sdhc. now i bought a new 64gb card (SanDisk MicroSDXC Action SC 64GB Extreme 90MBs SDSQXNE-064G-GN6AA; this one: http://amzn.com/B013CP5C02) and got this problem. yesterday the replacement card from amazon arrived but the problem persists.
This is my 3rd moto x (pure) edition, the first 2 I had no problems with using the same card, so I'm kind of assuming it's the tray on this particular phone, but I'm going to try and format the card and see what happens
I have seen this before on multiple "tray" devices... place a couple layers of scotch tape on the back of the card and reinsert it, adds just a bit of pressure to the connection... often enough since tolerences are pretty tight on these things.

S7 & S7E killing my SD Cards....GRR! Any ideas?

I don't know if it's something I'm doing, but this has happened twice now (both with an S7 and now my new S7E).
I bought my S7 with a SanDisk Extreme 64GB Micro SD. After a few months, I kept finding that on taking a photo, it was diverting to internal storage over the SD card. Rebooting sorted it for a while, but it reached a point where it locked itself and could only be read, but not written to. I sent it back to Sandisk and they issued a replacement.
Since then I've now got an S7E (I was part of the N7 scandal). I'm using the replacement Sandisk card I received and today EXACTLY the same thing has happened. The card has become completely locked. I can see the data that was on it from the S7E before it locked up, but I can't write to it. In fact, I can't even format it. If I put it in my PC I can read everything on it but otherwise it's bu**ered.
Where am I going wrong with my S7's and SD cards. Any ideas?
Cheers.
I had the same thing happen. My Sandisk 128gb got corrupted, sent it back for replacement to Sandisk. Then the replacement got effed. Then I bought a Samsung Evo 128gb and it got locked somehow. There are files on it that I can see with a PC, but when in a phone shows as corrupted. Cannot format, cannot do anything with it. I got another 128gb Samsung from Amazon and so far is working. I am worried it will do it again.
Can i ask which version of s7/edge you guys have ? I got the exynos model (n7 scandal as well) I popped in a 128 gb evo card, I'm worried it might do that to me :/

Mine is also Exynos!
Well for me, it started when I had the AT&T 935A S7E with the SanDisk, but I now have the Exynos S7E and it is the one that the Samsung micro SD went bad on. So both models caused issues. I do flash custom roms and things and know the risks, but have never had this happen on any of my S2, S3, S4, S5, or S6 phones.
I got the same issue but I think its the card with the HC card I didnt have problems but with the XC card it got corrupted...
Try a different SDCard manufacturer to SanDisk?
Possible the replacement was from a faulty batch of cards the original was also from
Think I'm using Kingston
Did you read my post? It happened to me with a Samsung too.
Same issue here with Silicon power 64gb.
Might be the whole XC thing.... I have an old 32GB Samsung EVO knocking around. I'm gonna see if I can kill it haha! Otherwise I'm going to have to send the dead one back AGAIN.
I had te same issue on 3 SanDisk cards all SDXC, I concluded to stick with SDXC, got for the extreme versions.
I tried everything to recover or format.

For those with locked files on the SD, what did you when sending it back?
Probably connext ur micro sd card to the pc and done diagnostics and correct disk sectors.

Doesn't work. Already tried that.
There is a command you can use on dos that fixes read write or bad partition errors on sd cards . Check this link

Yes that's what's I've run already on my cards. I have tried everything I can find. I do work in the IT field though I'm not a programmer. The closest I've come to getting somewhere is using an application called testdisk. http://www.cgsecurity.org/wiki/TestDisk It will help you recover any files lost but that isn't my problem. The one thing I will say is I'm pretty sure all mine have been formatted as eXfat vs fat. I had one go bad when I was messing around with adoptable storage.

I also used to work in the IT field! I spent about 8 hours last time trying to repair the card the first time around - in the end I just sent it back to Sandisk. You need to request an RAM on their web site.
And yea, no CHKDSK /f, or DISKPART CLEAN will touch it. It's so odd how the phone can render a card useless - yet still be completely readable.
I have an sandisk extreme pro 64Gb sdxc since april. Only use it for photos and downloads, sometimes to listen to music. It still works flaweless *knocks on wood*
Have you guys formated the card in the phone? This cause some really bad performance for me, i formatted it with my pc and SDCardformatter and the performance is better now. But sadly not as good as out of the box. Maybe samsung screw something up while formatting with the phone?

When this happens, the card is locked. If I format the card in the phone it claims to have worked - yet nothing has actually been formatted. If I use SDCardformmatter (or Windows, or any of the 3rd party tools) they all fail. "This disk cannot be formatted"!
Yes I have put them in the phone, and my card says corrupted when in the phone, yet works fine (other than being write protected) in my PC. I did request an RMA on my first 128gb SanDisk, then it happened to the replacement, then it happened to the Samsung 128gb, and I am on my 4th 128GB which is a Samsung EVO Select. I thought it might have had something to do with not doing the full wipe of data in TWRP recovery before switching roms. It does say doing full wipe removes encryption as well as wiping data.
