[Q] Weird SD card

First of all I'd like to say Hi to everyone I bought a 16 gb class 4 sdcard for my hd2. After few days of using my ROM started crashing so I installed new one, then this repeated. I went back to my 8 gb class 4 card and everything is working fine but it's not enough memory for me. So there is my question, is it possible to make something to make this card work normally or I need to buy better one ?

Which SDcard did you bought and what means "crashed" ?!

There is some wrong with your new card. I also faced a similar problem and I return the card. Then I got a another one which works well.

I bought EMTEC 16gb class 4 card. Crashes means it freezez phone, apps shows FC errors etc. So what card 16 or 32 gb do you recommend to our HD2 ?

i am using samsung 16 gb class 6 sd card and it works flawlessly..
no problems at all .. you should buy that one if available.

Sd card has 16 gb but only 896 mb shown?

My SanDisk sd card has 16 gb on it but on S4 and all devices it has only 896 mb? How can I fix it? Already tried reformatting.

Google search "counterfeit sd card". Maybe that is the issue.
Or if you have a windows 8 PC with an SD card reader and a full size SD card adaptor, try using the built in "Disk Management" utility to see the actual room on the card and to reclaim it if it is there.

they pretty much are I never had an issue with them just exchange it if you just got it and test it while your still in the store..

I have read about the San Disks having issues with this phone. Forget where. The 64gb Samsung solved those issues. They didn't talk about smaller Samsung cards. And don't remember if it was only a certain size San Disk card.

The OP said the card reported limited storage on other devices as well, but didn't say what other devices, so I'm thinking it is a problem with the card in general this time.

i'm running a Sandisk 64gb right now for about a yr had it in my S3 and now in my S4 and a 32gb sandisk before this one no issues

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.

Anyone using a Class 4 SD card on S4?

Hi!
I am afraid of buying a Class 10 card for my brand new S4 as I saw lot of bad reports on the only brands we have here in Lebanon (Sandisk and Kingston).
So I am wondering if a Class 4 of these brands are more reliable on the S4.
Are you using a Class 4 card?
If yes what is the brand?
Did you have a problem with it?
Will it slow down the S4 when taking photos or opening the gallery??
I don't mind waiting a minute or 2 when sending a big file from PC to SD if it will keep my data safe VS speed and unreliability of class 10

i use a sd card 16bg class4 brand trascend, in my gt-i9505and telephone is ok, very fast for all

I have SanDisk 16gb class 4, had it go corrupt (raw file system) 4 times using fat32. After I re did it as exfat I haven't had any issues after 2 weeks, *touch wood!

Is it fast enough for camera and gallery?

I've been using a Sandisk Class 10 for half a year now with my GS4 and never had any issues.
I don't recommend Kingston but Sandisk Issue as far as I know was sorted long time ago and why limit yourself to a slower Class 4.

Yes it seams to be ok but in comparison to what? I don't have any other sdcard to compare with, so mine could be really slow...
If I copy a 200Mb mp4 from internal storage to sd card speed fluctuates around 10MB(yte)/s

Tried the Transcend 16gb class4 from my Cowon on the S4, the test results given by the app ''SD tools'' gave 4.5mb/s write speed which pretty low no?
I wonder if Sandisk class 4 are faster in writing

I'm using a 32GB Class 10 Transcend microSD. Works like a charm. Better than SanDisk any day.
| Mobile Message

Used a Sandisk class 10 32gb microSD card for a couple of months, it gave me a lot of issues like random unmounting and photos getting corrupted. Got it replaced but the issues still persisted. Using a Samsung 16gb Class 6 now and i'm super happy with it. My mom is using a Sandisk Class 4 16gb microSD and doesn't seem to have any problems with it!

I just copied the 200MB mp4 to internal storage the speed was 17MB(yte)/s.
So the read write would be
10MB/s write and 17MB/s read I guess.
