Hi have a Lexar class 10 sd card that I purchased ~6 months ago for my Evo. Had issues with other cards, and this was the one card that was rock-solid for me on the EVO.
This morning, my Photon started acting very laggy. Programs would refuse to launch, and it was generally having issues.. Upon rebooting, my sd card was gone..
In windows, the sd card has a partition, but requires formatting now this card was rock solid for me in the EVO, so concerned that it died within 24 hours of having it in the photon

No issue here from my 2 year old 8gig and it has been in since Sunday.

I had problems with the same microsd card, and wound up having to RMA it. I've heard of others who have had similar failure issues. I'm highly skeptical that the Photon actively caused it, as opposed to just poor coincidental timing.

I'm a Sprint Launch Ambassador supporting the Photon and I would also recommend backing up the data on the SD card and reformatting it. Keep me posted on progress.

it was corrupted to the point of not being able to see it in windows
A recovery program that I tried (EASUS recovery) showed the files and gave me the option of recovering them, but since I didn't have much on there, I opted to just format it..

wow! my wintec 16g class 10 stopped working today , going to see if comp recognize it .. no cool!!
Sent from my Mopho 4g using XDA App
While I do not know about the wintec card, but the Lexar one has been known to do this. There are a few xda threads scattered throughout the forum as well as over in Amazon that have mentioned the card as well as a few others that work for a while and then poof they act like this. it seems to be common with 32GB class 10. Another one that has issues is Patriot (see xda thread) but at least Patriot has acknowledge the issue.

FYI. Estrong's File Explorer does not work correctly on the Photon. I have a 16gb sd card and Estrong's File Explorer will only detect 8gb of it. Use the factory installed file manager instead. I thought my card got wiped when I first got my Photon but that was the culprit. Windows showed all my files still intact.

Are you sure you're not seeing the internal media partition?

All I know is that when in Estrong's File explorer I can switch between sdcard and phone memory and it only sees 8gb of my 16gb card. Im very familiar with Estrong's File Explorer. I've been using it quite a while. Not sure what else it could be because the stock file manager on the Photon sees all 16gb of my memory card.
If you're not seeing internal phone memory, internal SD card, and external SD card) three separate locations) then you're just not accessing the SD card correctly.
Try browsing to /sdcard-ext

I have a microSD card in my phone and I don't have any problems with it not recognizing it. Maybe you have a bad card. Make sure the card works or the files you have are corrupted.
I a Sprint Product Ambassador and would love to look into this further to help. I need to narrow it down to any specfics I can get. So...
To anyone having the issue:
What was the brand? (i.e. Sandisk, Lexar)
Size of the card?
Any other information that may be pertinent.
One thing I noticed about file explorers in general, esfile explorer, astro, etc, they detect the internal memory as the sd card and not your actual sd card.
Also, I reformatted my sd card from my 3vo after backing it up, because in general when you put an old drive, or something similar into a new computer it may handle it differently than your previous computer did, in our case our phones. Now this may not be the case, but this is just my thoughts on how it may work. Which could in turn bork your card. Should be okay after a reformat.
Sent from the phone you wish you had, using the XDA Premium App.
Just had my SDcard become corrupted while in phone. Showed "Damaged SD Card" warning in Notification bar. I then had to reformat the card. It's working just fine now. I think perhaps some data while writing to card becomes corrupt.
Others report if you have similar issues.
My card is a 16GB Class 10 Patriot (I think)
I have an 8GB SD card in my Photon that used to show up just fine, but now the contents are no longer accessible. Under file manager, it says no SD card is present. But I also use App2SD and all the apps (games mostly) that I had moved over to it are still working. I can launch those games just fine and even in the App2SD app, it shows my SD card (total space and used space) along with all the apps on it.
When I take this same SD card out and plug it into my Win7 PC, all the old contents are still there (pictures, music, videos). I can view/listen to them just fine, so the SD card is good.
So I'm not sure wtf is going on. The only thing that I did that may have caused this was installing QuickPic. When I first launched it, it tried to do an index of all my content on the SD card. But now when I launch it, it says no SD card is present. I've rebooted several times, powered off/on, reseated the SD card, but the end result is the same.
Anyone have a clue on what I should do (short of formatting starting over)?
In file manager are you browsing to /mnt/sdcard-ext ?
I was able to browse there under QQPlayer, but it was empty. For File manager, I simply select SD Card (choices are Internal Phone Storage, SD card, Shard folders) and it says "Please insert memory card". But for further testing, I installed Zedge and moved it over to the SD card with App2SD. It still allowed me to do that and the app still worked.
Lemme guess....el cheapo no-name branded micro sd card ?
Wintec or some other crap ?
Time to go buy another....this one is toast with no butter

Keep guessing, it's a Sandisk. And like I said in the OP, it works fine in the PC and in the Photon, as far as App2SD is concerned, just not with the rest of the phone.

And you think it's a bad card exactly how? Are you reading my posts or just randomly responding with crap? If the best of your troubleshooting skills is to replace the suspect part, then point taken. However, I disagree.
So for other folks on the forum that have some basic troubleshooting skills, here's something else I've done to test. I've placed the SD card back into my old HTC Eris and the card works fine in there as well. So my guess is that the issue is somewhere in my Photon. Just not sure if it's the hardware or software.
Then live with a bad card
I have had issues with my sdcard, but not to the extent you seem to have. I swapped the Radioshack Photon for a Best Buy Photon last night to get a hunski back and backed all my apps up with astro. The only thing my new Photon recognizes are the pictures I had from the old Photon. My wallpapers, ringtones, apps, etc... are not seen by new one and Astro does not find any backed up apps. AND its a new 8gb ScanDisk. Weird.
Finally did a factory reset on my phone but still kept getting the same behavior. Called up Sprint, got a support ticket number and walked into a Sprint store for them to test it further. 2 other known good SD cards were failing to mount on my phone. Tried them on another new Photon and they worked, including mine. Luckily, I was within the 30 days period and was able to simply get my phone swapped out. POS Motorola...
Hi Folks,
now i snatched me an ZU because teh price tag of 222€ was to tempting. Mainly because i like strange phone Sizes... and why carry two devices, when you can have one awkwardly big one ^^
Now, I have an SanDisc Ultra 64GB Class 10 Card...
And guess what, when i fire up Comic Rack, it tells me that the SD Card is removed and tries to read it again.
Now is the Card Broken? I formated the card new, and after two tries my Laptop was able to format it? Sonds like something is messed up in the Card?
I still have warranty on the Card? so is it best to just send it back and get a replacement?
Thanks in advance.
EDIT:
I'm pretty sure the card is done. Walkman always freezes when it tries to read from the card
And it's said again that the card is removed.
Even with no activity at all the card struggles and is removed from device.
Thread is done. Mods can delete.
Thx guys
For the 2nd time in a week, I've got my SD card entirely reformatted by itself, and lost all my docs, photos, mp3... Not fatal, because I have most backups...
But I'm extremely mad at my Android (Samsung Galaxy A6 plus 2018, not rooted), as I can't understand how a SD card can get wiped out by itself and, I think, while on screen off. What app could have done that?
I've read that the card could be hardware faulty , but It worked perfect in my previous Note 4 android for a year, and never gave me trouble.
I also need some advice on recovering docs from the card, as I've lost my most recent photos. Thanks.

Well just picked up my new A52 5G really enjoyed it at first but now my SD card keeps getting unmounted every time I restart the phone. ( The best part about this is the SD cards are made by Samsung tried 2 different ones both are 128G) (SAMSUNG: EVO Select 128GB MicroSDXC UHS-I U3 100MB/s Full HD & 4K UHD Memory Card with Adapter (MB-ME128HA)
The typical SD problems Samsung is known for. Asking Samsung for solutions is not very informative. Please any suggestions would be great.
If not I guess I just ditch Samsung A52 5G and go back to the other evil the iPhone. Heck at least every time you turn that on it always works.
This sure seems like a great phone but that SD card issue is really a big deal at least for me.
HAve you tried the same SD cards on other phones or a different SD card on the same phone?
Yes, I actually bought 2 exact same cards, no issues anywhere I use them except in the new Samsung A52 5G.
Reading a lot of other posts seems to be a pretty big issue with Samsung and Android 11.
( https://eu.community.samsung.com/t5...afely-to-prevent-your-phone-from/td-p/2967455)
What about if you borrow a card from a different brand? I swtiched the old SD card i was using onto my A52 5G and never had any issues. Could it be a problem with samsung cards? For reference I use a Kingston 32GB MicroSDHC with UHS 1
Try formatting card in phone if that doesn't get it try doing a low level format on the PC with a 3rd party app do not use the Windows formatting utility.
Then format again in phone.
Load card through phone.
Formatting the SD card was the first thing I did using a Linux PC. (Manjaro OS ) This was always my goto if I have formatting problems. The SD card was done in exFAT, however no luck.
The other option is buy a different brand SD card as mentioned above by "ImGonnaTryScience". (Thanks)
The card I'm looking at is the
SanDisk 128GB Extreme MicroSDXC U3, V30, 4K, A2, Micro SD.
I'm thinking maybe the Samsung SD cards are to slow, but who knows.
What doesn't make sense is the Samsung SD cards work everywhere with no issues.
I even have an old Galaxy Tab 7, Samsung SD cards works great in that. Speaking of my old Tab 7 I tried formatting the SD cards with that and then put them back into the A52 5G. This didn't work either. My thinking was Samsung should like Samsung but my thinking was wrong. (Maybe I should stop thinking.)
Speed in SD cards matter sometimes (for example the SD card I use in my dashcam needs to be a certain minimum speed otherwise it won't be able to record properly), but I find it very odd that it wouldn't work for a phone.

Not giving up just yet, I really like the A52 5G.
V30 should be fairly fast from internal memory to SD card less using the C port.
If you did a low level format then put it in the phone with not data on it, then formatted in the phone again... it should work.
I've had issues like this on my S4, now you see it, now you don't. I had to do a low level format to make it readable even on Windows. May have been a bad card but all sectors were intact.
May be card brand. Even afterward it would not see the requiring a reboot.
I'm using the Lexar .5tb V30 card in my Note 10+ and unlike what happened on the S4 the 10+ recognized immediately. Formatted it in the phone and zero issues since.
OP I feel you. This is a frustrating issue that really jams a monkey wrench in the cogs.
I be seeing red.
Pedal to metal, no brains diagnostic solution; get the Lexar card if the size and speed rating fit your needs.
$64 and known to work out of the box.

Well I may have solved my problem. I completely wiped the SD Card using MiniTool Partition Wizard. However I didn't add a partition or any kind of formatting. Once the card and partition was completely wiped I put it back into the A52 5G and let it do its own partitioning and formatting of the SD Card. Everything is working really well no more SD card errors, just hope it holds. ( 12hrs and still working, before that the error would pop every 30 minutes or so.) ( Still using my original SAMSUNG: EVO Select 128GB SD Card)
I'll update the progress in a few days.
Some reason the wipe of the partition seemed to do the trick. I don't really understand why since like I said the card worked well in everything except the A52. Maybe Samsung changed the format structure compared to there previous tablets and phones. Maybe its even an issue with Android 11 . All formatting in the past was always exFAT however something changed with this phone. I hope this will help out others who may be experiencing the same problem.

It's possible there was some app on it with a secure partition or something.
It may take or do what one card* did in my S4+, while never lost data it would go through spells of not being recognized by the phone requiring a reboot. No rhythm or reason to it.
Having to low level format a new card is not a good sign.
Next card get a Lexar, slam it in, format, good to go.
* it wasn't recognized by the phone or Windows. Only the Lexar formatting app could access it. After a low level format it was visible to the phone and Windows.
Really?
Well I said I would let everyone know the progress. Simple terms FAIL.
6:00AM this morning the error came back. ( SD Card was removed unsafely )
So I guess now I'll try the new SD card I mentioned above or the one mentioned above by Blackhawk ( Thanks for the info. )

Format in phone.
I would leave the card in the phone and up/download data via the phone rather than removing the card to do so.

I have no love for 11 and running on Pie quit happily on my Note 10+.
Can't say that Lexar card is know good for your phone because it uses a faster and different memory controller as well as the imfamous A-11 OS.
However before blaming the hardware or firmware I would give the Lexar a shot. It's a nice card to have regardless.
Well I picked up the sd card member Blackhawk was talking about this morning. A Lexar High-Performance 633x 512GB MicroSDXC UHS-I Card. I put the card in fresh out of the package let the A52 format the card about 4 hours later same as before, the fault came back. After reading the post the Blackhawk wrote about his pie made me think I'll try that. Fired up my pie4 and let the pie4 do the format. Well no luck there either within 30 minutes the fault came back. Well now I know its either the A52 or its Android 11. The cards both work really well in all may other devices. However the A52 5G is the only thing running Android 11. Now the question is return the phone or wait for Android 12.

Sorry to hear that. I meant that Pie as in Android 9. Try the Lexar low level formatting utility if you can find it. Again, format in phone before you use it to be on the safe side.
It seems it's the phone.
Try clearing the system cache.
Doubt check setting and clear data in associated apks. It still may be something not so obviously obvious... Androids wuv being played with.
Well I finally got the respond for Samsung I was looking for. It's not the SD card but an issue with there firmware. They claim it will be addressed with the next update. I used the Samsung Members App to send them an error report from my device and the response was quite pleasing.
( See there response)
Congratulations, you're a remote Samsung beta tester!
Just sloppy and unprofessional on Samsung's part and no fix... yet.
Eventually they'll get it but it should have never made it out for retail sale like that
Personally I'd consider asking for a full refund as without a working SD card slot the phone becomes a liability for me... as if this little ride hasn't already. That used 10+ is looking more tempting to me.
Wow. Well done
Hi another issue with SD. When I have tried to make a backup on the an SD card via the setting app it stuck after 85% and the result of it I got an SD with "write protection" which I can't change not via DOS not with other 3rd party tools. by the way its working on Samsung tablet including format and copy files but when I put is back to my mobile or try to check it on PC to delete the portion or make any change it still same issue "write protection". Would appreciate any idea before I put it to garbage. Thanks
