Summary of limitations with Stock Firmware - Galaxy Tab 2 General

Putting these out there so that dev's could address and all others should be aware of:
- No "USB Mass Storage" support. ICS out-of-the-box doesn't support this, however it can and has been added into ICS-based roms for other devices. Definitely possible to be addressed via software.
- Cannot move/install apps to the external microSD card. With ~4-5GB of available space on internal flash memory, this can become an issue for some.
- supports only microSD formatted in FAT32. Which effectively means if you have a video or other media file that is over 4gb in size, you cannot copy it onto the card. This is certainly a problem when you have HD quality movies you wish to play back on the device.
- wifi "can be" flaky. Many have experienced "low" wifi strength while only a few feet from their routers. Possibly could be improved through kernel driver updates, etc.
Please add on to this list as you come across limitations!
[EDIT]
- Per Macadamia Daze: Lack of Ad-hoc Wi-Fi support
- Per doraemon14: No face-unlock enabled in ICS
- [ CONFIRMED WORKING ]: Support for USB OTG (Host Mode).

I'm not sure who all cares, but it lacks ad hoc Wi-Fi support.

this is my first android device so not sure if this is only for ICS or all other previous versions.
- hope charging via USB is working even though it is not power-off.

Most tablets now need 2A to charge, USB only provides 500ma. I don't think it works, it's not an ICS limitation.

thanks for the info. just assuming (more on hoping) it might also work while on power-on since charging via USB is working if the device is turned-off.

as far as the - supports only microSD formatted in FAT32. Which effectively means if you have a video or other media file that is over 4gb in size, you cannot copy it onto the card. This is certainly a problem when you have HD quality movies you wish to play back on the device.
I found that if you use a rar. format you can break the file up into small file. which let you put it on the sd card and then extract the file and put it back together in the card. it may take longer doing that but it works.

Bluetooth issues... device tends to pair and connect, then randomly disconnect, say it's still paired, then constantly pop-up the "Pairing" dialog asking for the PIN number. Once this happens the device will not stay paired.
This is happening with my PLX Kiwi OBD 2 adapter in my car... happens to my friend on the stock original firmware (I'm on the updated version) we're both rooted.. this happened before rooting as well though.
Two more cases can be seen here:

[Guide] USB Host
--------------------------------------------------------------------------------
USB host lets you hook up external USB devices to your phone, like a keyboard, mouse, USB drive, etc..
Unlike devices which are designed to support USB host, the One S doesn't provide power to the peripheral. That means we need a few more adapters/cables to get it to work (and we need an external power source).
Purchase links are listed for all the required cables/adapters.
You will need:
•USB Host adapter (The otherwise unused 5th pin on a micro-usb connector is grounded) dx.com/m-129671
•Mini USB power Y cable (this kind of cable is often packaged with portable hard drives) dx.com/u-65630
•Mini USB Female to USB A Female adapter This package comes with two, but you only need one. dx.com/u-55613
•Your charger
Assemble the cable:•The micro USB of the "USB Host adapter" connects to your phone.
•Your peripheral plugs into the female end of the "Mini USB Female to USB A Female adapter"
•The "Mini USB power Y cable" has three connectors:1.Mini USB connector - connects to the "Mini USB Female to USB A Female adapter"
2.Male USB A Power (the thinner wire) - connects to your charger
3.Male USB A - connects to the "USB Host adapter"
That's all. As long as your ROM supports the peripheral, it will work.
Some fun peripherals to try:•Powered USB hub (You can also power the adapter from one of the hub's ports)
•Keyboard
•Mouse (a cursor will appear on your device)
•USB flash drives and USB hard drives must be FAT32. You have to run a few commands to use a USB drive. Mount manually from the shell (use Connectbot or Terminal Emulator):
Code:
su
mkdir /media/sdcard/usb
mount -o uid=1000,gid=1015,fmask=0702,dmask=0702 /dev/block/sda1 /mnt/sdcard/usb
To unmount:
Code:
su
umount /mnt/sdcard/usb

UPDATE on BT!
I just called Samsung Mobile Support and let them know about my issue. I mentioned that the original and current firmware's both have this problem, the agent put me on hold for a few minutes and came back saying that they are aware of this issue and the next firmware update (OTA) should be resolving it!
Thank you Samsung for having great customer service (I was only on the phone with Samsung 12 minutes total, including the non-existent wait time!)

yeah, recap:
you:Im having a BT issue
sammy: please hold, *call developers on other line* *yelling at developers* Bluetooth is broken! fix it!
sammy: *back on call with you*, we're aware of the issue and will be fixed in an OTA update.
just kidding although I love pounding Sammy every chance I get.

Did you test any of this for this tablet? Does it even apply to this tablet (you are referencing a different device)? USB OTG (aka Host Mode) is a combination of having the right hardware + the right modules compiled into the kernel.

I had the same problem along many others(on original firmware it wasn't even usable it rebooted constantly). I was trying to connect to one of this:

I ended up returning the device as I mainly needed it for that a the moment and as it crashed using the browser etc, but thinking of buying again.
Did they give you an ETA for the update? Or have you tried another ROM?

FAT32 has a single-file size limit of 4GB. Yes, you could use rar or any other archive format to break the original file into pieces, however for example, an HD .mkv video file can be well over 5GB (single file). You could possible copy 1 of those large files into the 'internal' memory if you had the space -- but defeats the whole purpose of having expandable storage.

i dunno whether the one i write here is considered as flaws or not...

Understandable if you needed it working right at that moment. I did ask for an ETA but unfortunately he said he didn't have one... he did say that it will be soon and to make sure my device is on wifi and ready for an update soon.. but I'm on a rooted stock firmware and froze the software updater lmao so that won't work... but I'll keep an eye out for am update and let everyone know. No I haven't tried any other ROMs yet as they all have some flaws that bother me... not too mention for my specific use I don't really need anything too fancy... just need BT for my PLX Kiwi OBD adapter for my cars diagnostics

is there anyone has stock room for p3100?

It's still too early, but there are some ROMs actively being worked on (and I'm hoping we see official support for this tablet from CM soon). With the recent MacMall $219 flash sale on this (they must have sold thousands in one day), and attractive MSRP, there could be a lot of interest from major developers.

Ebay tells you how much have been sold. It wasn't 500ish last I saw shortly before it ended.

I purchased the Samsung OTG cable and plugged it in the port. The cable has a female connector on the other end. I plugged in a 32GB thumb drive and it read it right away. I plugged in a small harddrive and the tablet reported that a high power device was plugged in and would not work without additional power. I paid $8.00 for the cable on amazon.com.

Would you be able to provide a link to that cable?
Thanks for the info! Does a mouse/keyboard work with no issue? The USB stick -- did it auto-mount and what filesystem is it formatted with (ie FAT32)? -- I'm curious if for example a USB stick that is formatted in NTFS can be used..
On another note, this confirms that the device itself can handle USB OTG to some degree -- meaning the modules are in place in the stock kernel and the hardware itself is capable of putting out enough power to handle certain devices.

Has anyone tried plugging in a USB HDD?

i was wondering, what if i got a USB harddrive, and plugged it into my hermes?
would WM6 even notice its there?
this is assuming i've got a externally powered HDD that uses the normal USBHOST.
i searched "usb harddrive" in the hermes forums and not many things turned up..
If you have one lying around, give it a go?!

that might be the clue to your answer..... the usb port in the phone lacks the capability to host an actual usb device, whether the external device is powered or not... But give it a go anyway... i cant think of any harm in trying... unless there is some kind of major power backflow, but that shouldnt happen unless your external device is faulty
the OS may support it, but hardware-wise - i dont think the Hermes supports USB hosting? or does it?
My brain says no...
But the hope in me says yes...
Wondered about this myself before.
Doesnt the HTC have the ability to act as an external UsB drive through the USB port when connected to a PC using the Advanced USB settings. Maybe its just a question of reversing the settings maybe with an added utility or something i have an external hard drive but not converter to convert the full usb to a mini usb

having the device mimmick and external drive and plugging in external storage through USB are 2 completly different things... and it all comes down to the USB host... when you plug your phone into your pc your computer then is able to act as a usb host, as it has the power and the drivers necessary for that... the phone itself lacks the abiltiy to be able to become a usb host...
but hey, at least your thinking
So it may be possible to access a USB HDD if we catered for it using a driver of some sort (written by us guys ofcourse). This may even show up in the file manager as something like /Hard_Drive.?
main procesor (and also OS itself) have support for USB host, but for some reason HTS decide to not enable this feature, it was asked many times, but solution doesnt exist yet... I used this functionallity on my old Fujitsu-Siemens LOOX n500 without necesity to install any drivers, or registry hack, after connection device had available after few second. It was WM5 device.
well think about this:
keep a laptop usb HDD in your car, 160GB of music at your command, with TCPMP who needs a ipod?
i've already modded my stock headset cable to have a 1/8" miniplug AND RCA's on it, so i'm set for the output, but my 4GB of microsd cards just don't cut it
so i'm working on tryin' to find a usb mini b male to usb b male cable right now, might just have to solder one up myself-- i'll post to see how it goes.
I think I've seen them for sale at Radioshack and Compusa - might try peaking in there though if you have a bunch of USB cables kicking around probably cheaper to solder
IF you look around on the net somewhere, someone successfully made a wifi hard drive, and i think it was fairly inexpensive... He loaded tons of mp3's and would access them from his phone via wifi.

USB hosting ENABLED on XOOM!

While I know that honeycomb does not support this yet (but likely will with the sd card upgrade), there have been rumors that the micro USB slot on the XOOM is actually capable of hosting.
Does anyone know this for sure?
Basically, im trying to decide between the XOOM and the unamed Toshiba tablet.
I like that the Toshiba tablet has Hosting with a full usb port, and Im wondering if the XOOM will be able to do the same (albeit with an adapter).
Though, I dont even know if The toshiba tablet will release in the US any time soon.
ALL THANKS TO ROEBEET WHO HAS ENABLED HOSTING OF THUMB STICKS ON THE XOOM! - scroll through this conversation to get to roebeets post!
http://www.bestbuy.com/site/Motorol...1218305636450&skuId=1946179&st=xoom&cp=1&lp=1
Look down the page a bit for ...
Note: Optical drive not included
Compatible with optional external recordable CD/DVD drives (not included).
This would imply it does.
Yes, it most definitely will have that capability. Please see the thread here that I started a while back on the Moto Owners Forum, where I was able to get not only Moto reps to confirm this, but also was fortunate enough to get the actual Moto tech who worked on the Xoom's USB to chime in with some info. My guess is, the same software update that will enable the microSD card will also enable the USB host capabilities of the micro USB port (both external data storage).
The USB hosting being locked down software wise, at least initially, is being done to get some quick cash on their accessories. The unlock that they MIGHT provide later would allow 3rd party keyboards and other accessories access to the Xoom.
I really doubt that they will do a software lock later but the fact that it is software locked and not hardware means that someone here in XDA will be able to unlock it for us eventually.

look at the thickness of Notion Ink Adam becuase of 2 USB adapters
I did a bit of research on this.
So it appears the same situation exists for the dell streak. It also has USB host like motorola (confirmed by moto engineer).
Some guy here: http://linuxslate.com/cgi-bin/forum/YaBB.pl?num=1286562168
Shows how to get USB drives mounted and usable on dell streak running android 2.1 - this appears not to work on android 2.2 and higher.
OF NOTE: with the right cable (apparently some exist that support OTG hosting capabilities) and the right developer - we can absolutely get USB hosting onto the xoom.
Likely, a couple of scenarios exist to getting this working. First, we wait for the microsdcard update for the xoom - which may make it easier to host from the USB port; Second - we wait for a smart developer to port this sort of code into and app or custom rom; Third - we wait for the toshiba tablet to come out (as it has a full USB port for host) and steal its rom and port it to the Xoom.
I have a Nokia OTG cable that I misakenly bought for an Archos 32 (didn't work), and I tried it on my Xoom. I can use a USB keyboard with it, FYI. But a USB mouse I tested does not work.
USB thumb drives may not work as there's no mount point - I might try to create a custom boot.img and test that out, if I have time.

Can files be written onto the thumb drive or moved there using a file explorer?

Just bought one of these off the net for the missus so ill be active around these threads as well. Personally i have a xoom this will be like my second to flash the heck out of lol but as I've been reading about these i have a couple small questions
1. Is the sd card working on stock rom so i can flash customs or will an update to 3.1 be required like the xoom?
2. Does the usb port work as host out of the box?
3. Whats the general stable oc you guys are achieving?
I have tried to search these but some are hazy on the specs or they are outdated

Fastest claimed speed is 1.64ghz, stable closer to 1.5.
SD card does work on stock, actually is required for flashing. As yet you can't flash from on board only external.
USB seems to work for some devices not others depending on whether you use the full size USB or the mini. Look on the market for USB mount all, you do need fat32 not ntfs though
Anyone want to contradict any of this?
Cheers mate thats good to hear except for the host feature thats the whole point hoppwfulky i get a good one

Yes USB host [the fullsize USB not the mini] works out of the box. If your USB device requires power though - like some external HDD's - it may not work as there might not be enough power draw.
The mini USB is for the connection to your computer and SDK/ADB/general File transfer use - along side the Acer USB driver install [so make sure you've got the Acer USB driver installed on the computer(s) you plan on using to push files to the tab though mini-USB].

I asked the other day if about this being possible, and turned out it already is!
I´m a noob, so I´ve just basically tried a little bit. All I did was:
1) Rooted my Xoom 2 10.1" Wifi following the Root Method by Dan Rosenberg
2) Installed "Drive Mount" from the Market (USB Mass Storage Watcher did not work for me)
3) Plugged my USB OTG adapter (http://www.amazon.co.uk/gp/product/B006R0XOLO/ref=oh_o01_s00_i00_details) to my HD IN THE FOLLOWING ORDER: adapter to HD, then both to the Xoom (I was getting constant freezes because I was plugging my HD to the adapter, once the adapter was already connected to the Xoom).
4) With Drive Mount opened, I mounted my old, NTFS, already partitioned, external HD, and it reads it fine!
Not only that, it even gave me enough juice to connect an old Conceptronic USB hub, then my external HD, then a 8 GB USB pen simultaneously, then move a 700 MB movie to and from the USB pen, without problems. I´ve even been able to watch a 4 GB movie from it!
More importantly for me, this actually makes the device capable of making copies on the go, and hopefully, replace the USB pen with a USB card reader, and download photos and movies from you camera to a HD, when you´re on the go. That´s great for me!
Like I said, I´m just a noob, so the only issue is that I have no idea if the Xoom´s battery could be "damaged", or its life expectancy seriously shortened, by connecting that many devices simultaneously. I´d appreciate if you guys could clarify this for me.
Enjoy!

No, as it's a near-certainty (anything else is amateur hour) that Moto installed current-limiting USB "VBus" regulators on the line you're drawing power from (limiting it to 1/2 Amp).
Thx for number 3. When i plug the adapter first to the tablet and then hard drive to adapter , touch screen stops respond (the tablet don't freeze but you can do anything ). I couldn't understand why sometimes worked and some didn't. Strange bug.

I have the exact same bug on my Xoom 2 Media Edition, also rooted.
When I plugin the USB OTG Adapter first in the Xoom and then a USB Stick in the Adapter the whole touchscreen is turned off, you can only force reboot with the back site hardware keys.
If i plugin the drive to the OTG and then the whole thing in my Xoom all is working great.
Have to try this with a Hub and two drives, would be awesome to save my Raw Files during Holiday.
Hope Moto fixes this bug, because sometimes i forget....
hello pals,
does it really need to root the device to use it as described in here?
can I do the same without rooting my xoom2 (10.1 inch)

USB 3.0 Transfers fail

Hi,
I've been struggling with this problem ever since I've had the Note 3 ( since December). I've been unable to find a solution so am turning to this forum in the hope that someone can shed some light on this.
When I connect via my USB 3.0 port and select MTP (usb 3.0), then try to transfer a file from the note 3 to my pc, the progress bar comes up but sits there at 0% for a while then a message pops up "a device attached to the system is not functioning".
At this point going to other folders reveals no files although the current folder still shows them. This suggest that there is a disconnection of some kind.
Switching back to plain MTP this transfer will work but obviously at usb 2.0 speeds.
I am running Windows 7 and the usb port I have is via a card attached which is an Asus u3S6 (usb 3 / sata 6) card. The chipset on the card is a NEC chip and my other use for it is a bunch of external SATA drives in a USB 3 enclosure. Needless to say there are no problems with running these drives through the ports.
I have Kies 3 installed so any usb drivers needed for the note 3 should be fine. I'm stumped so anyone that can help me troubleshoot this I'd be grateful.
Have you tried enabling " USB Debugging " ?

Yes sorry I forgot to add that fact. It makes no difference.
Guess no one knows
i have somewhat similar problem, at some point of usb 3 file transfer the progress bar freezes and so is "my computer". interestingly the file transfer to note from the pc always works fine, but it always freezes at some point when copying files from note to pc, even during kies backup. usb 2.0 works flawlessly.
i've messed around with usb 3 drivers (asmedia) and even updated its firmware but the freezeups still remain.
gonna try usb 3 transfer on a different pc tomorrow.

This sounds like a different problem but I did get to the bottom of my problem which turned out to be the Anker 2 port hub I had connected to the usb 3.0 port. I didn't think to eliminate this but when I connected directly the problem goes away so the hub I had bought purely to extend the ports for convenience is faulty or incompatible.
Perhaps you have an extension or hub too in which case I'd make sure you connect directly.
USB3 seems a bit flaky in implementation. I had probs with my N3, a Corsair USB3 stick and a USB3 ext HDD. Problem turned out to be the ports on the PC. They would work with most devices but were intermittent or non-functional on others. Of course, among the USB3 devices it WOULD work with were the ones the vendor had. For some devices it behaved like the USB3 extra connectors in the plug or socket weren't long enough - push it in harder or push it sideways slightly and it would connect but drop as soon as you let go. (not good to do 0 USB carries power and this is a good way to get an arc across the plug and fry things)
The PC vendor gave me an add-on front port panel and all is fine now. Even though it plugs into the same port on the MB.
Note the USB3 HDD still pops up the 'check drive' error every time I connect but I haven't taken the time to nuke it and rebuild yet. But the Corsair now works and so does the phone.
Ah, the joys of the MTP protocol...
Same issue here. As well as it stops responding halfway through a transfer, crashes the connection when making a new folder, takes about 3 years to copy 1GB, randomly disconnects...
My TF700 started doing this after the 4.1.2 update removed UMS. My S3, same story. My Note 3, same story. 29 different computers, 4 different systems (XP, 7, 8, OSX). Different cables, different ports, with and without drivers, with and without USB debugging.
I bloody hate MTP. It's useless, limiting (because now it can't be used as a drive to attach to a mediaplayer via USB..) and about as stable as nitroglycerin during an earthquake.

I thought I'd give up on hubs and just get an extension as my USB3.0 is on the back of the computer and not that accessible.
I've seen a lot of complaints about hubs and simple extensions that have this poor connectivity which seems crazy to me since it's a bit more important to have a solid connection on USB 3 plugs, besides which it's not as though the usb connectors are rocket science.
I'll try the extension and hope I get a reasonable one.
well i did try the usb 3.0 file transfer on a different pc with a different usb controller and it worked fine, copied my 5gb music folder to the pc without any problems. so in my case i guess it's some incompatibility with the asmedia 104x controller (i did connect directly in both cases and the same cable was used).

it seems like it is indeed MTP issue here ! i rolled back to the old 2006 microsoft driver and i managed to do a full backup including music and everything else with kies. but after a while i tried again and it froze up again, i'll keep experimenting.
Sorry to resurrect this 3 month old thread but is there any way to fix this?
Whenever I want backup anything from my phone storage to PC, I have to do it in chunks of like, 50 files or less (huge PITA with TiBU). If I try to copy the whole folder, my computer locks up and I have to hard reset it. I've tried everything mentioned here short of buying a new USB3 controller.
