Galaxy S4 killed my 16GB Kingston microSD

Ok so I turned on my p hone the other day and it says "SD Card damaged, please reformat". I ejected it and put it back in, and now the phone acts like there isnt an SD in the slot. Wtf. Anyone know why Samsung phones destroy SD Cards? And could anyone recommend a card it wont destroy? Ive heard good things about the 64 gig Samsung card but idk..

Can you read it on your computer/laptop?
I would try reformatting on the phone after dumping any data to your pc.

agreed

Did you get this card on eBay? Or from a reputable store? As others said - make sure you try the SD card in a computer or elsewhere.

I believe this is just a fluke issue. I had the same problem. I shut phone completely off for 5 minutes turned it back on and everything was fine with me. So before you go panicking try shutting phone off then back on.

I also have had this happen with two separate cards. The last time it happened the data was a complete loss. Unreliable if you ask me.

16gig any brand should not be having issues at all, format fat32, and it will work, now 64 on the other hand, s4 and 64g have serious issues playing together.

I have an 8 gig and 16 gig card that I have used for YEARS and my S4 runs them just fine. I don't really think it's the phone.

I've had this issue a few times on my SanDisk 64GB. I panic at first, then just reboot and wait and it comes back fine... No data loss (yet) but I have everything backed up anyway..

only one thing to do, kill the S4...

I have never ever had any issues with the micro sd card on any of the Galaxy's phone. It might be a bad card. It's not your phone that killed the Kingston micro sd card. If your phone was a killer, it would have killed internal sd first before even killing this innocent 16 GB Kingston micro sd card.

OP I TOTALLY feel your pain! I've killed 2 64GB SD cards with my S4 since it was new. They were both sandisk ultra class 10 cards. I finally got a Samsung brand, and haven't had one single issue! It even runs faster than the sandisk ones.

Kingston SD cards .... the *** NEW Kingston SD *** cards are now working with Samsung devices.
My first Kingston 64 GB SD card stopped working months ago and asked Kingston for a RMA and they sent my new card. Now this new card has stopped working as well ... i asked Kingston what the problem was and they mentioned the the last batches of 64 GB SD cards were not compatible with Samsung Phones. I have two (2) Kingston 64 GB SD cards. Check the numbers on your Kingston SD cards NOW...
the two cards i have now are being returned via RMA and the numbers i have are
31461-001.AOOLF
NO427-003.AOOLF
Please check your SD Card numbers now and BACK UP your SD cards and

sdcard goes bad

I just lost my second 32gb class 10 Sandsk SD card in the S4. I didn't take the card out our do anything special. The card is now unrecognized in my computer and phone. This is the second SD card I lost. Any ideas on what may be causing this and how to possibly repair a card that isn't recognized?
Sent from my GT-N5110 using xda premium

Try a card reader and pop it in a computer. Mine went unrecognized after a hefty download from the play market failed. So I copied everything off it and put it back in. And it worked. After backup if ur pc sees everything u can format it even once in the phone. Good luck

Just ordered a SanDisk 32GB sd card also except mine is class 4... wonder what the difference is, hope it doesn't happen to me :fingers-crossed:

It is disturbing at the cost of these. Fortunately I have a backup that isn't too old and I decided not to move all my apps to the SDCard.

The class is a speed rating.
A class 10 is 2.5 times faster than a class 4 at reading from and writing to the card.

I have just lost my second 32 gig. Lots of data lost. Can this be coincidence. I am worried and will start to back up the next mem card for piece of mind. I will guess the first one worked for 1 year and the second for 2 hope thurd times the charm.

Found out what the problem is with 10.1 2014 stuck on start up!

The problem is if you have an sd card. Guessing there's fault where it's taking to long to read it. I've had no problem with this. Got a 32gb sd card today. It's a samsung class 10 one too. Went to restart my device . Got stuck on start up. Tried again. But this time when it got stuck I removed the sd card and instantly it went to lock screen. Weird fault but if you have an sd card only way around it is to take it out while its booting up. Hope this is to help to anyone. Any comments or similar thoughts?

Did you accept an update while the SD card was inserted in your N10.1-14? It can randomly change the device to "custom" status which could cause issues with certain DRM protected content. Rebooting (maybe twice) corrects the issue. Later Samsung devices have occasionally corrupted SD cards too. I'm using two 64GB SanDisk cards in my N3 and SM-P601 and haven't had any issues even after accepting updates. It's kind of "spin the wheel."

I have no issue booting up with my 64gb Sandisk inserted.
You should format that card again perhaps.

Ok I've played around a bit more trying to reboot it about 4 or 5 times but it gets stuck In a loop. Flashes the lock screen for a couple seconds then be to the the start up samsung logo. It will keep doing this over and over again. Took the sd card out... worked straight a away. Weird!! An y ideas?

Ok I downloaded an app called sd booster and I selected for my internal storage to be selected at boot up. This seems to have solved it. Lost everything on my sd card though and it is having trouble reseting it

New stock update now no sd card

My s5 is a completely stock UK model on Tesco/O2. It's had a couple of system updates.
I last did one a couple of days ago and now the phone won't recognise the sd card. It initially flashed the message "sd card unexpectedly removed" (or similar).
I've tried restarting, removing sd, restarting then putting card in. All to no avail.
The card works fine in my son's s4.
Any ideas please?

Have you backed up and reformatted card?
I'm having another problem, in that I can't get music to my SD card!
Have you got music on your external SD card?

No music. Got a few films and work pdfs.
I'm wondering if anybody else has any problems after recent updates

Just remembered something. When I tried to move a couple of movies to the sd using ESFILEEXPLOR it wouldn't let me. I managed to move them with the stock file explorer though.
I was reading another thread about compatible sd cards and it seems there are a few people with issues, mainly caused after transferring music to the card as opposed to leaving it in the system memory

I heard there were a few problems with this stock update and I was trying to avoid it because my phone was fine, no problems with really anything. It updated when I connected to WiFi... oops. Now it won't read my SD card and pretty much every time I unlock my phone, it tells me to check my back cover because it thinks it's not all the way attached. Realllyyyy annoying and I have no idea how to fix this.
Edit; I'm on an att s5

The warnings wont go away unfortunatly but had no sd card issue....if anything after update my screen was unresponsive till i pulled the battery

If you tried on two different devices than it is probably just a problem with the SD card.

Brand new and formats no bother on computer etc. Androids formatting seems to be struggling with it.

Wont even format smaller cards either.

You could try installing TWRP and format the SD card in TWRP.

I am trying to remember if Ive done that already [emoji23]. I have rooted tablet so will try that again.

It could be that the card is counterfiet. There are a lot of them on the market. I bought 4 of them on Amazon, each from a different supplier, that were all counterfiet. Put them in a PC and they would appear to format to 256gb and pass the Win 10 check disk. But they would only write 32gb of data, even though the copy routine would appear to succeed. Copy 50,000 song Karaoke library to 1780gb of disk, but only the first 32gb would be readable. I will no longer buy large capacity SD from anywhere but Newegg.
