As I've posted a few times in this forum I think Google excluded the SDcard on purpose due to issues with the use of an SDcard with Android 3.0 and higher. I've seen this first hand with my Xoom tablet.
Here is a recent post by a developer on the Motorola Xoom forum on the details.
https://supportforums.motorola.com/message/493078#493078
Android is a really wierd beast. As much of the functionality in Android OS really isn't Anrdoid functionality but is functionality provided by the linux kernel and services underneath. Below might be a little over some folks head, but kind of sumarizes everything I currently know of the "external storage" issue with 3.2 and ICS going forward
Right now as it stands in Honeycomb 3.2.2:
SDCard
Tablet recognizes external SD Card and mounts it for R/W (/mnt/external1)
Special new android permission required to write to sdcard
Permission exists but is only to a few specific services in Honeycomb
Permission can not be requested by installed applications so they can't directly write to external SDCard via Java file IO commands. (apps can request permission for internal SDcard /mnt/sdcard but not external)
This means no write access using traditional Java.File IO methods you have to access files through the MediaStore provider API's as it can access the files for you. (Am working a utility app for this)
USB Storage
Linux Kernel in Android recognizes USB volumes when plugged into Xoom (but doesn't mount them)
Vold Daemon (http://vold.sourceforge.net/) is not configured (on GED device) to mount USB volumes when connected to device
MediaScanner/MediaStore service in android appears to scan all mounted volumes, but has issues with volume removal and doesn't store volume name with file information (covered in depth in other threads)
NO USB Storage mouting/read/write as configuration of Android default config doesn't have it setup
ICS - What I know so far:
External SD Card Storage
Issue of External SDCard access could be solved at either Kernel Level (just fix permissions on mount point) or Android Level (make android API for file access easier to use)
Don't see any evidence that anything has changed at the exposed API level. BUT the API's might be doing stuff differently on the back end that makes things work
The undocumented permission for accessing the external storage that you can't request for an application in 3.2 doesn't seem to be documented in 4.0. (Still don't know if an app can request it though)
Don't know if additional applications are given the "special" permission by default in ICS. In 3.2 things like Camera App, MediaPlayer, Email, etc don't have "special" permssion to write to external SDCard.
Don't know if they are changing the mount point locations in ICS, which could also change how its accessed. (permissions, priviledges etc)
USB Storage
No new documentation or changes (in SDK doc's at least) on MediaStore or other API's that traditionally deal with media storage.
Since most of the things keeping us from using removable storage are "behind the scenes" stuff there is no way to know if this will work or not untill Google tells us, or we have ICS and can test it.
MediaStore API "technically" has correct fields in current API's to allow it to support multiple removable storage devices, but with out more documentation, source code, or binary code there is no way to know if back end was updated to support it. Content would still need to be mounted by Vold first though.
Important to note that Google coould have implemented removable USB storage support just with modifications to Vold config without making changes to Android API's. And it would have some functionality (as it does on Custom Made Xoom 3.X roms) and it wouldn't show up as a change in the SDK docs.
Google made a big deal about how they were looking at new ways of handling external/removable storage in a way that made a file's location irrelevent/transparent for the user. Based on those comments earlier in the year I personally expected to see many more modifications to storage and file handling API's. All throughout the Android documentation they mention this is how the API's access the "primary" storage, but they don't get into details on how to access "secondary" storage, but they do hint that it exists.
The API's in theory could have been extended without changing their call arguments (just add new options to existing function arguments). But if that has occured, then its not in the current documentation. Incomplete documentation of the SDK is fairly common though on major revision releases from google, as their developers aren't exactly the best documentation writters.

They didn't have SDcard expansion on the Nexus S either....
The Nexus S also didn't have an SD card slot. Would that be the same reasoning behind that?

That could've just been a way to show off the new support for devices without sdcards that was a new feature in Gingerbread though.

Wait, what? The Motorola Xoom shouldn't have an internal SD Card. With Honeycomb, the internal storage of a device is only partitioned into boot, recovery, system, data, and cache. There is no FAT-formatted partition on the internal storage that is mounted as a fake "SD Card" partition, because starting with Honeycomb when a device is connected to a computer file transfer is accomplished using MTP with the help of a FUSE daemon. So since there is nothing mounted at /mnt/sdcard if all you have is internal storage, then if you plug in a real SD card it should just mount at /mnt/sdcard and apps should be able to access it just fine using the old API and permissions used to access SD cards that have been in Android for generations.
Basically the problem he described boils down to Android's inability to deal with apps reading and writing to multiple external partitions. The API only deals with one external storage partition (http://developer.android.com/guide/topics/data/data-storage.html#filesExternal) so if you have a device with the internal storage partitioned like, for example, the Nexus S, where a large chunk of the internal storage is in a FAT-formatted partition mounted as if it were an SD card, and if this device also has a slot for a real SD card, then apps can't request permissions to read and write to the real SD card because the API only lets you deal with the fake internal SD card.
But this shouldn't have anything to do with devices like the Xoom and Galaxy Nexus, where there's only one internal storage device and on that device there is no FAT partition mounted like a virtual SD card, so any real SD cards you plug into the device should just mount as regular old SD cards that Android has always worked with.
EDIT: It just occurred to me that on devices like the Xoom and Galaxy Nexus, probably a directory on the /data partition is mounted at /mnt/sdcard so that poorly programmed apps that hardcode that directory to use for external storage will still work. Unfortunately this means that the API for accessing external storage will only be able to return file objects pointing to this portion of the internal storage and won't be able to make use of a real SD card. Until the Android API is enhanced to let apps read and write to multiple "external" storage partitions, this is indeed an issue.
I believe ICS will have full support for sd card slot.
Why?
There are lots of devices that can be upgraded to ICS, and it has sd card slot.
Otherwise, people will be mad if they upgraded to ICS, then the sd card slot becomes read only :-*

It won't be read-only. They fixed that in Honeycomb already. However, apps still won't be able to read and write to it using normal file IO operations. They'll have to use the MediaStore APIs. Assuming nothing has changed from how it works in Honeycomb right now.
Personally I think we are giving Google/Samsung too much benefit of the doubt here. They are not putting in an SD card slot for the same simple reason that Apple doesn't have expandable memory on their devices; so that they can charge us more for higher capacity models. If they actually had a good reason for it then they would have explained it officially a long time ago.

The other reason is that they can control the speed of the storage. How many class 2 sd card disasters are out there where the person didn't know it was a slow card and wouldn't work with video recording, or even slow the experience down?

I have an asus eee pad transformer and it has had full sdcard support (read and write access for all apps I installed) since its release with honeycomb 3.0 and it still has now on hc 3.2. Xoom was just crappy in this case. So this cannot be the reason for no sdcard on GN. But as some said before, the Nexus S also didn't have a sdcard.

Docked the transformer actually handles 2 SD cards and can also handle additional USB drives just fine. They get mounted to /removable/MicroSD and /removable/SD.

Then why did Samsung put an SDcard slot in the SGSII models? And they're surely going to sell millions more SGSII's than Galaxy Nexus'. If they wanted to make money they should've taken SDcard slots out of the SGSII.
I think they did internal storage only on purpose, but not to make money... my guess is its for speed and chassis space reasons.

That's right, I own the dock also. But even without the dock, SD card worked perfectly from day one. Additionally I think that ASUS offer the freakin' best support in terms of fast Android&firmware updates and (useful) pre-installed apps (like Polaris Office, Supernote, Splashtop Remote, MyLibrary, a nice File Manager, ...) of any manufacturer I know. But that's off-topic now

Bingo. This to me sums it all up.
True, iPhone 16gb - $199, 32gb - $299. Not bad, 16gb extra for $100. I'm not sure it will work the same way with a Google phone. It's the exclusivity, you want an iOS device then you'll have to buy Apple's, with Google you have many other options and manufacturers.

Well, Samsung did it with the Galaxy Tab 10.1, it has no SD slot and on introduction the 32gb version was $100 extra.
Which is rather rich considering that a high quality 16gb microSD card can be had for $25. As an extra insult the internal memory in todays devices is almost always eMMC, which is more or less an SD card made to be soldered down, it has no better performance or features than a normal SD card. So it's a $75 markup straight into the manufacturers pocket.

Format your card with exFAT & you should be good to go. If you go that route, make sure you are using CWM since TWRP doesn't support exFAT SDCards.

What does CWM and TWRP stand for?
How do you install CWM on the Galaxy Note 2? Is there a link for this?
cwm is clock work mod. it is a replacement bootloader like the bios on your computer. it requires you to root. i cant remember what twrp stands for but its a competing bootloader.
TWRP= Team Win Recovery Project
Anyone knows a good, reliable software that formats to exFAT? Or does windows offer the option on it's own when trying to format? Still haven't received my micro sd, but I want to be ready for when it arrives.
Also, are there any cons to using exFAT, besides TWRP not supporting it?
the phone itself should do exfat samsung licenses the patent for it from microsoft. the stock format is fat32.

FAT32 is the limitation that will not allow >4GB file size. That is not a problem on exFAT or NTFS, but I'm not sure SGN2 reads either standard.

Partially my fault for not researching jellybean...just read about how smooth it was & didnt expect them to take features away. I recall reading the article about the bs reason saying people confuse the internal & external memory. U would think they wouldve learned from wp7 when they took away sd support & started being like apple. I figured it was bs article. I wasnt even planning on buying a phone but my 4g slide tapped out after a few case less drops. I was just gonna buy another mytouch since theres not much of high end qwerty selection but gn2 note caught my eye.
I was sort of mad too, but around 10gb for apps has been plenty for me when I put everything else on external memory.

It's not that people confuse the memory. The problem is that when an app is put onto your SD card, it cannot sync correctly with the operating system. Therefore, Google is doing what they can to keep users from putting apps onto their SD cards. Hence the lack of the SD slot in Nexus devices.

u sound like a pr rep lol...im still a android newbie but Ive never have ne problems with apps relating to my sd. If a app/game works best or only on the phones memory most developers ive came have stated up front it even back to my wm days.
I'm pissed at this too. This app2sd and the "no more free tethering" thing is pushing me over the edge to go rooted.
I'll never buy a Nexus because of their flawed philosophy that Google has adopted:
1. Non removable battery.
2. No removable storage. "Everything belongs in the Cloud" I call BS!
I've got a 64 Gb SD card that's somewhat useless if I can't install apps on it. And since only the 16 Gb versions of the Note 2 are in circulation it's very disappointing.
The ship has sailed. Google hates external storage. Don't expect to ever see official OS support for it going forward. It's irritating but reality.
I agree this is total bs. I will not buy another phone that doesnt have external sd. Had an Htc one S and I hated it for that reason. (sense is terrible also)
Hope there's an easy fix soon since I use the GN2 as my table and smartphone now. Didn't have any issues before since I had most games on my N7 but now I'm out of room
There are work arounds. But real fix as of this date.
This is Samsung following Google wishes. I just hope the GN3 will have at least 64gb of internal storage. Then we can use the SD the way Google wants SD cards used. The worst part is that many apps that download media content into your device doesn't allow to save the media content within the extSdCard. That is really annoying. Without being able to use the extSdCard as a media content storage then what does Google expect we use SD cards for?
Samsung is part in fault too. Samsung is well known to put too little storage and main memory into PPC devices. I remember my Samsung Omnia i910. I had to move so many files from the main memory into the storage memory and even into SD card. Then I had to work on other files, like the registry, ini files, etc.. to point to the files I moved. All just to get more space within the main memory for more apps. Windows OS, even Windows Mobile, added major files within the Windows directory every time you install another app that took so much room within the smallest main memory. Samsung is doing similar with GN2. 10gb is barely any room now days with Android.
Samsung needs to lead the pack all the way. SD card, large screen and large capacity of removable battery, 1.6 quad-core, 2gb RAM is not enough to lead the pack all the way. They also need to lead the pack with 1080+ res screen and 64gb+ internal storage memory. I feel that Samsung miss the "leader of the pack" mark with GN2. Samsung needs to realize they are competing against other Androids as well as iPhone.
But the blame starts at Google on app2sd issue.
Switch internal to external(sdcard)
want to have more app storage space for your HD games and what not, here’s a simple App2SD script you can use to store all of your apps on your microSD card. *This will essentially swap your internal storage with your microSD card and allow you to use up to 64GB of space (if you use 64GB microSD card).This should work on all the Galaxy Note 2, test on international GT-N7100, T-Mobile SGH-T889, and Sprint SPH-L900.
Step 1. First, you will need a rooted Galaxy Note 2. *This will work on any custom ROMs except CM10 or AOKP.
Step 2. Second, I highly recommend you to format your microSD card before using this. *Also, after formatting you can copy the contents of your internal storage to your microSD card
Step 3. Download the script on your phone: downloadandroidrom.com/file/GalaxyNote2/app2sdNote2
Step 4. Install and open Script Manager app on Play Store.
Step 5. Using Script Manager app, find the app2sd script on your microSD card and enable “SU” and “Boot”. Step 6. Reboot. *You should now see your microSD card used as internal storage and internal storage as microSD card.
Will this work with a rooted phone but with stock rom? How effective is this method?

I've been running the storage swap script for a couple months now with no issues. I've used it on stock based roms kernel s along with custom ones as well. I'm using a 32GB fat 32 and am not sure if it supports exfat on 64 cards. Go look for it via search. It's in the sgs3 section somewhere. It's truly a lifesaver for us app/game hoarders

This really is more of an issue with app developers not allowing data to be stored on extsdcard. They would only need to pop up a box with options of were to store the large data files. It could look like this:
search device for sdcard implementation (/sdcard, /extsdcard, /sdacard/ext/, etc.)
pop-up box displays radio button with each storage location, really cool deb's would add option for custom location.
Set location to variable, use variable throughout program.
Just my 2 cents, I think that either this needs to occur or google require a set way of implementing internal/external SD cards.

I have a post in the themes & apps forum with an app I found on the market that let's you store your game data onto an sd card.
It's called gl2sd, you can check in that forum (there's a direct link to it), or just search the market.

Excellent point, friend! You always make good/useful comments and could always use more users like you.:highfive: A few minor points, I do miss move to sd option so the lack of kinda falls in line with this forced move to dropbox, cloud, lack of sd card etc. Oh sh!t don't get me started on the Nextel line these days. I have to say the manufacturers and Google are just as responsible as developers. They're all guilty really lol Besides those poor moves though, Android is doing great. I am so glad I preordered that G1 many moons ago. I guess its all who you ask I guess and sometimes we are stuck in our old ways... even us techies. Fo example, I was really stubborn about qwertys and surprisingly don't miss it. So who knows? It's either we're too stubborn to change or we don't like being told what to do.... maybe both Either way, the storage swap script works flawlessly once you set it up properly. As I mentioned earlier, not sure about 64 exfat but I'm sure you can switch it to fat 32 plus all you cm10 fans will have done this already. Hope that helps some...

I have not seen much information on having your nandroid seamless with the GS4 and able to also use the XFat system too.
What's with XFat? you might ask.... It's the fastest read/write system yet that is available to us GS4 users...
My backups used to take like 45-50 minutes, now it's a tad over 18. Recoveries are as well much quicker. Copying data ie. movie files, or the like, to the external SDCard is a whole lot faster! XFat gets the Class 10 SDCards performing at it's rated speed. Not to mention movies have better playback definition as well.
How do you get this performance gain?
I re-formatted the External SDCard using XFat. I was using FAT32 before due to the inability to use CWM on the XFat format, but I found out that this version (and probably other flavors as well) now supports XFat.... and so does even the Stock Sammy ROM does.... (proves that the hardware is well capable of it.)
Go here, and if you're using anything that is capable of read/writing to an XFat format, get the file!
http://goo.im/devs/philz_touch/CWM_Advanced_Edition/jfltetmo
You can get either:
philz_touch_6.15.4-jfltetmo.tar.md5
or
philz_touch_6.15.4-jfltetmo.zip
of course the "Zip" version is cwm installable right from your recovery, and the md5 one is easily flashed using Odin.(PDA)
I am impressed with this version, as it's very customizable.... Screen colors, menu colors, screen dimming, etc. and so far, I have had nary a problem using it. I like the fact that it will reboot the device after the completion of a backup or recovery, so I really don't have to "babysit" it's operation....
Sorta like a Ronco TV Informmercial product.... "Set it, and..... Forget it" LOL
Anyway, I just thought I'd share the information that has put a whole lot of spunk back into my aging GS4!
Good Luck and Aloha!

In theory, yes. However those specific cards have been known to fail. Not because of formatting, but just in general. There is a specific set of serial numbers that were defective. You'll have to search to see what the range of serial numbers is.
As for backups taking 40-50 minutes...that's the recovery more than the format of the card. Philz is just known to take forever. For all it's benefits, speed isn't among them.
Twrp takes about 5-6 minutes for a Touchwiz backup, 2-3 for an AOSP backup. Doesn't matter what the format of the card is. But TWRP isn't as fancy and customizable as Philz. So it's a tradeoff.
Ill keep that In mjnd thanks

Hi,
I recently bought a Lexar 633x 128GB SD Card that is rated at 95Mbps. Formatted with Android exFAT, the card shows only 20Mbps in Android but in Windows, the same partitioned card shows 96Mbps. I therefore suspect that the problem lies in the cellphone' software or its compatibility with exFAT extension. I have no option to format other than exFAT with Android. I have tried ext4 with TWRP but Android will not detect or mount it even with the mount command.
Any ideas on how I can get the right speed out of the card?
p.s: I am running the latest 2.19.40.22 firmware for ZE551ML
Have you tried formatting to fat32? You'll need to download a program separately to do that on windows
Hello,
FAT32 does not support filesystems larger than 32GB from what I have read. Windows only gives me the exFAT option. Is there a modded tool to bypass this limit?
Is ext4 faster for large files sequetial read?
thanks
EDIT: I found the utility and it works ok under windows but it freezes the cellphone after I insert the card.
@aziz07 hmm, what software did you use to format it? I used this. http://www.ridgecrop.demon.co.uk/index.htm?guiformat.htm I always felt fat32 was more stable on my Android device. It doesn't freeze my phone though my sd is 64gb
EDIT: actually, I just did some benchmarks and it looks like it does only read around 20mbps, regardless of the SD I use.
What are you using to test speed? I have a 64gb Evi and sometimes music stutters a but over Bluetooth. Not sure if it's a slow card, a problem with power amp, or just something that happens with Bluetooth audio occasionally

Just a random SD card benchmark app lol (a1 SD card), I would say that is more likely to be a problem with Bluetooth because you don't need high speeds for audio playback.
Yes, I used the same format utility but my card is 128gb. I will try again. May I ask what allocation unit size did you use and what is the fastest one?
thanks
Edit: I used the default allocation size and it worked. Its because I changed it to highest value before. I don't know if A1 app ratings are real for read but it shows 201mbps read and 47mbps write. I manually copied a 800mb file and speed was 48-62mbps write. For sure, its caching in RAM somehow to achieve 201mbps read. I guess the 20mbps was surpassed as I was getting ~12mbps write before. Worked A+
Try reformating the card. Whats the make of the sd card?
I had kernel mods applied long time ago though. ZRAM at 1Gb, noop scheduler with 2048Kb read ahead.
I like FAT32 because its the most compatible and the fastest for flash memory from benchmarks.
You guys using the 128gb card show all ur space on phone? Asus was telling me it will only show 64gb.

Same here. Yes, eventhough its advertised as 64gb sd card limit, 128gb cards work perfectly. The thing with FAT32 is the 4Gb file limit, many HD movies or high bandwith video shootings will require >4Gb files. I am still not able to mount ext4 formatted sdcards though. TWRP would recognize but not Android ...

Sorry I completely forgot to check back on this thread. I'm glad to hear its working better with the default allocation size, I think I probably changed it to the highest as well because after formating with the default size as well its working great .
