I'm using a 16gb card now but I want to upgrade to a higher capacity. I don't really know the difference between Class 4/6/10 or the different types out there. Also, does the S4 actually support 64gb and had anyone got it to work?
Thanks ahead of time.

The 64 gig works fine once you are booted into Android.
There is a huge difference in classes of cards. I wouldn't buy less than a class 10. I would suggest a class 10 "pro" that has read speeds up to 70gb/sec. I had a class 10 sandisk that was 64 gb in my phone. I just learned that my backup clockwork recovery will not access a card over 32 gb. I just bought a 32gb samsung class 10 pro card from Amazon. It was nearly $50 but the speed tests on it are much better than the old class 10 sandisk. If you plan to root and use custom recoveries and ROMS, I would definitely suggest a good 32gb card. Hope this helps.

if you're planning to go 64GB, it comes out of the package exFAT. Some ROMs and custom recovery does not read exFAT and needs to be formatted to FAT32. As mention, get class10 due to transfer speeds.
Samsung 64gb Class 10 Pro
Old thread but just an fyi...
I bought the Samsung 64gb Class 10 Pro and it did come formatted exFAT.
Just to see what worked and didn't work, I left it like that and copied all of my music, data, videos, etc. and put it in the phone and everything worked great with one exception. CWM recovery doesn't read it, I was bummed because I am a die hard CMW user.
I went ahead and installed TWRP and it reads the card fine, I have made a complete backup and then a restore and all worked well.
Guess I will get used to TWRP
Hmmm so Samsung Pro card over Sandisk?

I thought it was custom kernels that had the problem with exFAT due to licensing (and not open source). Not meant to exclude CWM as I understand there is an issue there as well.
Just format the card fat32
Here is a good explanation of the differences between the different formats.

It is speed. Sandisk has the fastest random write speed which is what seems to cause those lock ups. SD card class is just measures one (relatively unimportant) indicator of SD card "speed" (sustained read).
Sustained read and write are great if you're using your card to backup large media or picture files but more or less worthless for running an operating system. Same principle is in place for SSD. Manufactures advertise sustained transfer rates but the important stat for a OS drive is access time (which determines the speed of random read/writes).
Here's a link to a 32gb sandisk for $30 http://slickdeals.net/da/mem-i/p46847290/k4569/u125110/r4
These work just as well as the 16gb ones.

32gb is theoretically the maximum, since 64gb cards will all be part of the new SDXD standard. Then again, several people have found that the 64gb SDXC cards work in their SDHC devices so we'll just have to wait until someone tests one in the nook color to know for sure if it'll support it (I wouldn't hold your breath, our hardware is fairly old).
I can certify that the 32gb works fine, as can numerous others who I've seen post.

Yep, same here. Stupid FAT32 doesn't let you copy files bigger than 4Gb though, so that sucks. Now if only there were some way to format the SD card using EXT2,3,4 or whatever, or get the Tab to easily recognize exFAT.
I did notice when i tried to copy a file from the internal memory to the external memory
It didnt work while i was unrooted. But since i have rooted i have not experienced this again..

I use 64 GB card and no problem.
Most manufactures says their devices is supporting microSD up to 32 GB, but really it's just a phrase.
I've tried 65GB microSD on my Galaxy S II and it worked then I tried it on my Galaxy S I also worked !! which made me try it on little Sony Xperia mini and also worked !!!
Just try it, Im sure it will work.
Yep no problems over here either.. Just need to format the card when it's in the device..

I have 64Gb Kingmax MicroSDXC. Works fine.
Confirmed a while ago:
http://www.androidnz.net/2011/09/sandisk-64gb-micro-sdxc-cards-confirmed.html
My 64GB card has worked in every Android device I've tried it in, check that blog post for my list - also confirmed working in many other devices by others.
looking to maybe getting a micro sd card, not sure if i should go for the 32gb with price range of $30-$70 or fork out the extra money for 64gb, over $150. what would you guys recomend? and is it even worth it going for the 64gb at this point? i have the 16gb tab and using 16gb from original 7" tab.
Well.. currently the cheapest one i could find was at play.com and that's not cheap at all... can't we use the usb adapter and connect an external HD to the device?
I went ahead and bought the 64gb card ($152USD on Amazon) as I like to keep as much as possible on my tab. As far as a usb hard drive, I would think it would need to be on that does not need to be powered through the usb connection.
it works just fine, i have 64GB almost used up on my SGS2
In terms of whether the 64GB is worth it: only you can answer that. Mine is basically full and I would like even more storage, some people can't even fill an 8GB card, so it's quite a personalised thing really.
You can use pen drives via the USB adapter if that suits your use.
It seems from other posts that 64Gb cards are entirely satisfactory but my additional question is "What class is optimal?" There are Class 4, Class 6 and now Class 10 cards with price generally higher for the higher class. I note that another poster has successfully used a Kingmax 64Gb MicroSDXC which, I believe, is Class 6.
Does anybody know what the specs are for the MicroSD slot on the tablet. Obviously, it would be overkill and a waste of money if the device cannot read and write at the higher speeds that the card supports. Has anyone done any benchmarking?
I was considering a 64Gb Class 10 card for AU$125 but am wondering if the tablet can actually make use of it and a cheaper card would suffice.
the Sandisk 64 is a Class 6
http://forum.xda-developers.com/showthread.php?t=1343164
I think when it comes to the difference in class, the simple explanation is the random access speed vs sustained data transfer speed.
Correct my current understanding if I'm wrong, but generally speaking, lower class = faster random access speeds, but slower sustained data read/write, whereas higher class = faster sustained read/write speeds, but slower random access.
Can anyone confirm or expand upon this?
that's why a Class 6 is just the sweet spot right smack in the middle of both
yeah Class 10 are faster to transfer huge files but slower on smaller files
and class 2 to class 4 are faster for smaller files but extremely slow for huge files like a 4 GB movie file for example

Aren't speed classes for the microsd cards themselves and have nothing to do with the device loading them? Or are you asking up to what class will the s3 support?

I'm considering...
Samsung MicroSDHC Plus Memory Card - 16GB, Class 10

You might want to go for the fastest class you can afford. This way, when you plug in the sd card in your computer you will be able to load it up quickly.
I really don't like waiting to finish a 30gb dump of data due to a slow sd card.

So when I got my S4 I had a 32GB sandisk card (don't know what class it was, came with my HTC thunderbolt). Needed more room, so I bought this. My sd card f*cking unmounts 4/5 a day. When it does I have to reboot it and take it out until it fixes itself. Then it'll go a week or two without any problems. My 32GB sd card did the same thing, just not as often, and I gave that 32gb sd card to my girlfriend who got the AT&T version of the S4 and it did it to her a few times, she accidently had the phone format it, now she has no problems... the 64gb is formatted to exFat, I'm in the processs of formatting it to fat32 and transferring data as we speak, but am I the only one with this issue? I read on the CleanRom thread that S4 have issues with SanDisk brands, someone said they switched to Kingston becauee their S4 wouldn't mount their sandisk.
Is it software / root related? because my girlfriend is stock unrooted and hers works fine and it's an older card but it's also not the same size or class (honestly I know it's not just asking maybe there's a mount issue with debloated firmware) Or is it a defected card/phone?
The card itself is fine. Reads fine on my pc. I checked the sectors and partition with Ubuntu gparted utility and it passed the tests... but I still heard they can be defected and it's a big problem and they'll replace it.

TL;DR: Buy a class 4 SD card
I bought the S4 on day 1 and started having the unmount issues with my 64GB SanDisk Class 10. When it started messing up my Spotify, I knew I had to try and figure it out. Well after testing with 4 S4s (2 of them mine as I returned my first S4 because of this issue), and a bunch of SD cards, I really think it comes down to the class. Class 4 provides a faster random write speed than 10s do, and I think that might help the issue. Both class 4's that I tested did not (and have not) unmounted once yet.
I bucked up the cash and bought all of these cards brand new for the testing. I ended up returning the Class 10's that I could and keeping both the Class 4's - 1 for a co-worker.
SD Cards Tested:
SanDisk 64GB Class 10 (x3) - One was brand new
SanDisk 32GB Class 10 (x2) - One was brand new
SanDisk 64GB Class 4 (x1) - Brand New
SanDisk 32GB Class 4 (x1) - Brand New
I have an open case with SanDisk and they are testing one of my 64GB Class 10's right now, and then are supposed to send me back another new 64GB Class 10 to help solve the issue. Pretty sure that one is going to unmount too though :silly:

Fat32 is only bad for 64gb cards because fat32 apparently doesn't officially support file systems over 32gb. 32gb cards obviously don't have that problem.

Hello, I need a definite answer if the p780 (im on s124 stock rom) can support a 64gb micro sdxc. Official specs say no but apparently some people tried it and it works.
Would really appreciate knowing before i waste money on a 64gb samsung evo or sandisk ultra
Bought SanDisk Ultra 64Gb, reformatted to FAT32 (it comes as exfat formatted), and had no problems.
Running ROW_227 on 2014 CN version.
Maybe the phone can also handle exfat, but I wasn't in the mood to copy 32Gb of data to the new card and then find out it doesn't work
FAT32 has it's disadvantages probably, but so far, card works well, total capacity shown is 59.45Gb on phone.
Yes, 64GB sdxc works. I have 64GB A-Data Premier UHS-I with file system fat32 and everything works fine. I am using ROM life v. 07

Perhaps the only difference between working or not, is the way you format it ? Both myself and the other poster have converted it to FAT32 before usage...

I just launched into my TWRP and learned that it can't read the sd card. Anyone have that trouble with fat32 format?
Okay. Got it working with TWRP. Just have to make sure it is set to primary instead of logical and it runs fine: Backup, restore, and file management.
