Personally I purchased the Sandisk 32GB card but both cards should work fine. Check out this thread for more info: http://forum.xda-developers.com/showthread.php?t=1150369

I would go with sandisk just make sure it is authentic

sandisk it is

Sandisk. Mine behaves like a Class6+ card, and is able to deal with everything the phone asks. Great value, would buy it again.

Definitely a Sandisk. I bought a 32gb Class 4 from eBay. Handles everything I throw at it with ease. Authentic and real card too! c:

I am getting a transcend card for less price compared to Sandisk.

Which one is worth buying?
Transcend is cheap compared to Sandisk.. So do they differ in performance?

Well it really depends on how you plan to use your card. Do you plan to use it for storage only, or a mixture of storage / application use.
If you plan to use the card purely for storage, then I would suggest you purchase a class 10 card from any vendor for the faster read speeds.
However, if you plan to use the card for storage / application use, then I say go for the Sandisk card. It's been shown to provide the best in term of random write speeds which is essential.
Unfortunately I wasn't able to find a CrystalDiskMark report for the Transcend 32GB class 4 card so I can't comment on that.
Hope this helps.

Better read speed around 20MB/s
http://forum.xda-developers.com/showthread.php?p=15269669

Sandisk performs better even at the same class.

Been using a Sandisk 32GB ( Original ) and it performs fine, transfer speed is a little low only going as high as ~6MB/s but mostly 5MB/s sustained.
I use it to store HD movies, first time though it stutters when playing something its a 3.87GB file and it jitters at fixed locations of the movie, I placed the same copy in the internal sd and I dont get the same jitters.. Im not sure if its the card not fast enough or its a sign of the card going bad.. other movies with a lower file size like 3.3GB plays w/o any stuttering at all.

Hi guys, I'm a new owner of the GS2 (got it 6 days ago) and I would also like to ask about micro sd cards.
In particular, anyone having bad experience with ebay orders? Like fake products (ordering a class 6 card and getting class 4)?
Was thinking about 16gb class 6 sandisk, I don't think that I need 32gigs. Or should I go for 32? I mean, I really can't imagine filling all that space...
Thanks in advance!

Ordering from Ebay nets you mostly fake cards as in the size you ordered turns out to be extremely less than what you purchased. Like a 16gb card turning out to be only a 2gb card.

32GB or 64GB MicroSD cards for Galaxy S3

I picked up samsung galaxy s3 today and looking for a good sd card. i am considering these two options:
SanDisk Ultra 64 GB microSDXC Class 10 UHS-1 Memory Card 30MB/s with Adapter SDSDQUA-064G-U46A
and another by Samsung
Samsung 32GB High Speed MicroSDHC Memory Card
samsung one seems like a good deal, compared to pricey sandisk.

64gb because it has exFat format 4gb+ file won't be a problem. I have got the same one.

Hi,
I bought mine from amazon a few months ago and costed me 78$ $54 Class 10 64GB Micro SD
You should get a 64gb card, because you will have a lot of space for yout stuff and you can format it as exFat!

No issues with it formatted at exFat? I know someone else with a S3 had issues and had to format it to FAT32.

64gb because MOAR IS BETTER! I formatted mine to FAT32 because from what I've read and experienced with my other devices, it's just safer that way. I've had issues right off the bat using exFAT on some devices (mostly Samsung) or gradually the card will become corrupted (I've lost about 3 full microsd cards full of data so far). From what I've read this is due to Samsung using a half baked implementation of exFAT. exFAT is a patent-pending, proprietary file system created by Microsoft, so if Samsung, or any other OEM wanted to use the full implementation they would have to pay licensing fees. So while you can format it to exFAT using a PC, the way Samsung devices handle it there is high chance of it getting corrupted.

How do you format with FAT32? Just using format option in Samsung S 3?
I've been experiencing problem where from time to time, it just corrupt and give me SD card error, and refuse to mount it. I have a 64GB Sandisk Micro SD on Verizon S 3.

I used my laptop's built in SD reader that supports XC cards and just formatted to FAT32. You can use any PC program that formats. I personally used an app called guiformat (http://www.ridgecrop.demon.co.uk/index.htm?guiformat.htm). It's a simple app specifically to format stuff to FAT32. I've heard you can simply use the window's formatter but I've also read of some people that had issues with that.

help lol
hi, Im a noob. Im getting galaxy s3 today. I been reading threads and searching within the tread but someone say something some one else says something else. so Im confused! especially since im noob. Which one is it for god sake!!! lol
Q. Which is class is better? I hear on other threads a class 2 or 4 is good but a class 6 and 10 is not necessary because for a higher speed the manufacturer use the randoms speeds, access speeds to make it faster. That class 10 don't necessarily means better,class 10 is too fast for for the phone that it will freeze or ppl having problems. You need a class 6 for apps2sd or Data2sd.
So im thinking a class 6 would be good for me since I use apps2sd alot, roms, I will download some music, vids and movies. 32gb class 6 SanDisk - Mobile Ultra 32GB microSDHC Class 6 Memory Card bestbuy sale 4 $30 has anyone body tried it?
Can someone who really knows tech stuff about sd cards answer plz
Thank you, sorry for all the questions...

I've personally been using Class 10s for my devices and haven't had any issues as long as it's formatted in FAT32.

The difference between the sdhc cards and the sdxc cards is that the xc are intended to be used on usb3 systems so that they can take advantage of the speed. This is important when you are loading the card with your music library or unloading it with your photos. (and you don't do it mounted inside the phone.)
A Sandisk 64GB sdxc class ten card won't get the 30mb read speed advertised. It gets regular class 10 speed, the gs3 has no speed improvements when using this type of mcard. Here's a speed test in the phone of the Sandisk 64GB sdxc I got the other day.
IME, exfat is sensitive to power level change and anything that stalls or disrupts any read/write operation. However, if the phone says that it is damaged, just put it in to your adapter and a pc with exfat support and run chkdsk /f (with the fix options selected).

Hi. I'm getting the SanDisk 64gb class 10 tomorrow. So formatting it using the phone will make it FAT32? As previously mentioned in the thread it isn't worth formatting to exFAT, right?

The default system as far as I know in SGS3 is exfat. Use a free downloadable tool by name mini tools and format the card to fat 32. I have a 64 GB micro sd class 10 sandisk. I have no problems using it . My 32 gb card was running out of space because of music files If you are getting a new card you can do a surface test with the tool i mentioned above so that you know whether it has any defective sectors. It does take some time though.

This is correct, it formats exfat on the 64Gb. I did this yesterday and using myTerminal app, the mount command shows that the card is formatted exfat.
Now, it's an interesting thing, exfat is a licensed format, and Samsung paid for a license, however anyone with a rooted phone has some sort of Busybox installed which replaces most of the exfat commands with Linux standard ones.... is this better or worse?
I have a question for the people who have formatted fat32, how big is the space on the 64Gb? on exfat it's 59.47Gb what's yours?

Thanks for the reply guys. As I'll be using files bigger than 4gb exFAT would be the best choice. I've read in some threads though that this file system corrupts in the s3 over time, she was the card fills up. I don't know if this is true since it was only mentioned thrice in 3 different posts. Can anyone verify this?

My old 32gb is mostly standard stuff that I keep from phone to phone (like contacts backups music). So I have a copy on my desktop. Anyway, I had 29Gb filled on the card as a normal condition with Nandroid backups and TI backups.
When I was transferring this to the new 64Gb card, I was trying to use a 4 port USB OTG with the old card in the USB stick adapter. I fumbled with the power supply to the 4port and the phone didn't like it and unmounted the card, and wouldn't mount it again. I put it into my desktop with an adapter (on XP you need a patch for exfat from MS) and ran a chkdsk /f on it (took some time as I don't have USB3). The chkdsk finished (I made a backup to the desktop since some of the nandroid was new.) and put the card back into the phone. It worked for a few hours, I was listening to music on the card. The battery ran low, and I shut down to swap batteries and the card wouldn't mount again and claimed damaged and needed a format. Since I had everything backed up (and still had the old card, too), I just formatted it in the phone. Used the OTG to get the data back on from the old card. Everything's been good since 30+ hours without turning the phone off. But as I write this, I swapped batteries (full shutdown) and when I rebooted, the card wouldn't mount (and doesn't say that it's corrupted).
It also takes more than a minute (maybe two or so) to mount the card when the phone boots. This also makes it totally unusable for applications being stored on it or data for applications on it or for swapping apps like App2SD where it links the external card to the internal card and visa versa. If the app tried to access data on the card while it's being checked, it may not have the code to support the error returned. If the app needs to be running at bootup, few are going to wait until the card is ready, and the os will query for the card. I know that this was a problem on GB, and is one of the reasons so many oems are including more very fast internal storage in the phones.

Thanks guys. I would probably try exfat and see it works... FAT32 is always an option!

Just got my card an hour ago. Right out of the box I tried copying a bunch of files and I encountered an error. Reformatted it using windows and now it runs fine. So I guess it would be best to format it again and not use it right out of the box.

fwiw. I kept trying to mount the card, and finally got to the point where it said it was 'corrupted'. I put the card into a windows box without problems, could read the data, etc. Ran a chkdisk /f to find and fix any errors, no problems. Tried to put it back into the phone and it still wouldn't mount. Gonna give Samsung a call since it works in Windows, it either Samsung or Busybox that's the issue.

I ran a chkdsk /f again, no errors. Then I downloaded the sdformatter from the sdcard working group. https://www.sdcard.org/downloads/formatter_3/ this is a free formating program that will make sure you have formated to the sdcard org standards. You can not choose the file system. You can choose to do different types of erase as a part of the format.
Anyway, after the chkdisk, I tried to mount the card but it would not. I then made another backup of the data, and did a long format (exfat) with a simple erase rather than the zeroes erase. Copying the data back and lo and behold it mounted. My phone though hasn't been off since though. Since I don't have usb 3 the formatting and data transfers take hours to complete. I am going to have to get a usb3 card for at least one pc and a usb3 card reader.
Samsung was not any help and wanted me to do a factory reset.

Ordered a 64GB class 10 from buy.com today for $48 shipped! Should be perfect for me brand new GS3 :good:

So which Micro SD card DOES work? Please Report in.

I thought I would start a thread on which Micro SD cards were recommended vs. those that fail early or are simply not compatible. I saw a thread earlier that appeared to show that some cards (and sizes) were better than others.
I can report that the Samsung 64GB card (says Class 10, HC, 24MB Read, 7MB Write) does NOT work in this tablet. I was able to use it just fine in my Note 2, and a laptop. However, the card doesn't work properly in my 2014 Note 10.1. An older Pansonic 16GB MicroSD card worked just fine however. I've tried formatting it in other machines, and it's still a bust. Currently, these cards are selling like wildfire on Ebay for $30.
So, what DOES work for a 64GB card? Any help is appreciated by myself and I'm sure a lot of others reading this forum.
Thanks in advance.

I have got a SanDisk 64GB card in mine. Also got the same type in My Note 3.
The SD card issue seems a bit odd, both of my cards were also fine in my older Note 10.1 and the Note 2. I've never had a problem with either of them

Samsung 64GB works just fine.
I have a 64GB Samsung MicroSD and it works just fine, haven't had to do anything to it, worked right out of the box.

Hey guys, thanks for the info. After some research I discovered that this was indeed a fake card I ordered from Ebay. Looks like this is a common problem as the packaging is *almost* perfect and you really can't tell the difference without some serious research. Luckily, the seller refunded the full amount back to me. Based on your feedback here I've ordered a SanDisk Ultra from Amazon.
Thanks for the help and & Happy Thanksgiving!

A really good way to check them is to simply try to fill it up. Only 4G of data will be saved and readable, whereas the other 60GB is corrupt.

It's sad that a lot of people get duped into buying fakes. But sites like ebay don't/can't do anything about it.
Memory cards/Usbs should only be bought from reputable sellers only (Amazon, Currys, Play.com etc) as there are wayyyy too many fakes out there.

I'm currently using a Transcend 64GB SDXC UH-1 Class 10 card which was formatted using the tablet.
It works fine except for one annoying problem. When transferring large, singe or multiple files, say 1.5GB+ HD movie or a huge amount of photos, from internal to external storage, the device would freeze. After it starts up again i notice that i can no longer access my SD card even though the device says it's still mounted. The only way i can fix this is by removing and reinserting the card or rebooting the device. Although there's no problem transferring files from a computer straight to the SD card.
Anybody encountered a problem like this? Is there anyway to fix it?

Yes, I'm having the same issue. Except the SD card will randomly lose the files even though it still shows the card is still mounted. Just recently I was watching a movie from the sd card and this happened.
I am using a SanDisk that was being used in my note 2 for the past year (never had problems with it before).
This is especially frustrating when trying to sync files with Plex.
Anyone have any ides?

Same for me

I know I'll sound like a noob, but my 32gb Samsung micro sd card just doesn't seem to work on galaxy note 10.1 2014, yet it worked perfectly fine on my previous note. Would i have to format the card on my computer? A little bit annoying since I don't have a reader for it.

My Sandisk does not work
I have a SanDisk Ultra 64 GB microSDXC Class 10 UHS-1 Memory Card 30MB/s SDSDQUA-064G-U46A that has a lot of problems working in my GN 10.1-14. It has worked fine for a year in the old Note 10.1. The New Note would not even format it. Formatted it in my Galaxy S4, and it kind of works. Often it simply reports no files, although it will report in Settings the correct size and space available. Sometimes I have to reboot several times for the card to work. then sometimes I will try to open a file and get an I/O error. Then sometimes random reboots, especially if I try to unmount it.

I use a Samsung Pro 64GB microSDXC (UHS-1) Class 10 card (MB-MGCGB/AM) reformatted to FAT32. Works great. I've been using the same type card on my LG Optimus G for almost 8 months 100% problem free (also formatted to FAT32). I did have issues with a SanDisk Ultra 32GB in that same phone that used to dismount itself all the time and I know others that have had issues with SanDisk cards in GoPros as well.

ok, so which one of these sandisk ultra microsd cards will work in the 10.1 2014 edition, and what is the difference between them?

[Q] [Micro SD] Anyone having issues mounting a Lexar 32gb?

Hi guys,
I doubt I'm the only one here.
I got my G4 (h812 LMY47D)and im ecstatic about using my micro sd slot (S6 was the main deal breaker paying top dollars for more storage) but now I'm running into issues with my Class 10 micros sd from Lexar, This darn software does not want to mount the thing (tried several format including a full 40 minute format @ fat 32 default allocation).
The G4 detects an SD card but won't mount it. This thing works flawlessly on my old S3 so it has to be software related as using a cheap Kingston 1gb class 4 works fine.
Anyone else running into issues with their sd card?
Thanks for sharing any info or tips.

Are you sure the g4 does not require different format. Been awhile since i had this issue. Was a format issue for me.

gonna have to give them a call as their user guide states
WARNING Some memory cards may not be fully compatible with the device. Using an incompatible card may damage the device or the memory card, or corrupt the data stored in it.
Not to found about this flagship! having issues reading a descent memory brand when an old rival device of 4 years is capable of doing so...

FIX
Just taught of leaving what got me to sort this out after playing around... Fun times :good:
After tinkering around with another SD card, the LG device formatted it to FAT16.
I've formatted the sd card using http://www.partitionwizard.com/free-partition-manager.html under FAT/Primary
It created a 4gb partition and left it the remaining untouch
Popped the SD on the G4 and it finally mounted the partition
Performed an erase via the phone 2x to make sure and the entire 32gb is now accessible.
Hope that helps others having mounting issues.

I have facing same problems with my 64 GB sandisk sd card on new LG G4
can you explain the procedure to make it work

I've been using an AData 128GB for the last month or so with no problems. I turned the phone on yesterday morning and for whatever reason it went straight to my home screen but locked up and took half a minute or so to unlock and then goes to the lack screen, then I also got a SD Card inserted notification, I figured nothing of it and ignored it. The micro sd runs fine on other devices (formatted as ex-fat) but it causes that issue on startup i mentioned above as long as it's in the phone and it also refuses to mount.

I'm using the SanDisk SDSDQUAN-200G-A4A 200GB ULTRA MICROSDXC UHS-I since 2.5 months ago formatted in exfat with 128k clusters which was what it was out of the package and it works fine.

SanDisk is the only one with something larger than 128GB at this point in time and notice it's 200GB instead of 256GB as size usually doubles in capacity, heard the 56GB was used for something else or maybe not usable. I have a new 200GB card in there now. There is a 512GB card coming soon from Microdia as well.

Microsd getting unmounted and remounted

I just installed a new 128gb microsd (sandisk ultra), and for some reason it keeps unmounting then remounting a few seconds later. I tried formatting it but theres no option in the settings. Is there any way to fix this? Is it only an issue with cards > 64 gb?

I face the same problem with 64gb SDxc sundisk card!!!!!
Any help....... please

I had 64gb microsd fitted last few months, a Sandisk card. No problems at all. Recently fitted a Sandisk 128gb card from Amazon.
Had constant unmounting problem, reformatted to fat32, and still unmounting virtually every hour. Draining battery fast as well.
So, fitted 64gb Sandisk again, problem solved, it doesnt like 128gb card. 128card now in a Win10 tablet and working fine !

Although ASUS only qualifies 64GB MicroSD as max, you should be able to use up to 128GB as long as it is formatted as FAT32. Some users had their's work fine with this size.
Zenfone 2 supports microSD, microSDHC, and microSDXC, with speed class up to Class 10
Sincerely
ASUS_USA

Thanks for reply Asus_USA. It could be a compatibility issue, the card I tried was a Sandisk Ultra SDXC class10 (newest version) supplied by Amazon.
Has anyone else had any success with this microsd in the Zenfone 2, I have the 32gb, 4gb ram version.

I have a similar issue. Read the forums and it is obvious many asus ZenFone owners are experiencing this problem. Can't asus just admit the problem and fix it and announce the fix? Or is it a bigger issue that asus will not publicly admit to?

I thought I would chime in as I too am having the same issue with my phone. I put an sandisk 128gb sdxc card in my phone when I purchased the phone it worked fine until New Years Day when I got an OTA. Since that OTA, the 128gb card will keep mounting and un mounting itself. I put an 64gb card in and for a whole day, did not unmount once. Called amazon to replace the card thinking it was the card, amazon gladly replaced the card, inserted the card and it is still unmounting-remounting. Like I said before it worked for 1 month straight with no issues in Dec. before the OTA, but after the OTA, its intermittently unmounting-mounting. Thought Id chime in since ASUS was responding and noticing others having the same issue. Obviously its a software issue with ASUS.

There are already so many issues regarding to sandisk sd card on Zenfone, I used to have the same problem, then I replaced my sandisk with samsung, problem solved.

Thanks for your help! I kind of figured it was the sandisk card because I put a little 64GB sandisk card in and the phone wont even recognize that card at all. I put a sony 64GB in and it held perfectly for 1 day, no unmounts. Off to Amazon to purchase a Sony 128GB!

After updating the latest version 2.20.40.160, my micro SD Card Adata 64G is assembling and disassembling every hour.
In previous firmware version that did not happen.
Something bad that ulima update.

My Adata 64gb card did that on the previous update, and more often at times. With the latest, the problem ceased.

i have 16 gb and facing the same problem. Maybe the cause of this problem is the firmware it self. try to update to the latest firmware

Have you tried formatting it to fat32 and remounting it?
From what I've tested, exfat has given me issues. But I'm on a custom ROM (CM 12.1 based), so YMMV.
If you're rooted you can try Aparted on the Play Store and not bother with the PC route. Just make sure you know what you're doing!

That latest update definetly caused issues with SD cards not over 64Gb but with specific manufacturers. Of course ASUS will not assist in this nor claim responsibility as this was in improvement update. Even though it was quite large for improvements. I would like to see what they say as even some 64GBs cards are not working either and they approve all cards upto 64GBs. Unfortunatley, your going to have to switch card manufacturers to get your card to work. I put a Sony card in and it works fine now. I could'nt get a 64GB sandisk to even recognize let alone the 128GB mounting/unmounting. Good Luck!

Having the same problem with 128 SanDisk (also class 10).
Looks like I'll have to buy a new card - am I better off with 64 GB or changing companies?

Yes.. it's a know problem, without a concrete solution... also me I purchased first.. read after... so I sold and I bought a kingston 128gb and since then, it works flawlessly (except it's 3gb less, but I seriously actually don't mind )

Luckily I had a 64GB and a 128GB card and they both had issues. So I just left sandisk all together and went Sony 128GB and it works flawlessly. It just seems like sandisk and this phone does not get along.

Both of you that have 128 GB but other companies, no issues experienced at all? Are you also on the 32 GB version and which firmware?

I have all sizes of sd card , 16,32,64,128 and 200gb...
I have both the 32gb phone and the 64gb phone. I have used exfat formatted sd cards, both 64 and 128gb, in both with no problems. I haven't tried the 200gb as I use that in my tablet but it is the ONLY Sandisk I have... All other cards are Samsung or the 128gb Lexmark. I have these as Sandisk had problems in other phones too... Never had a problem, ever, after changing away from Sandisk...
Sorry, should've added I'm on 178 firmware - the latest...
