Can't see SD in MTP mode

I've been having troubles connecting in MTP mode since I bought this 32GB AData UHS-I uSD card.
First, didn't connect at all, deleted MTPApp data, checked "Install PC Companion" and sometimes it connects BUT I can't see the SD.
All is working in Mass Storage but it seems like MediaGo does something wrong and I can't see my music in my phone.
Also, I hate having things not working in my phone.
How do I fix this?
Thanks in advance.

Me too....
But im too lazy to search for it. I just use MSC to transfer files....

This happens to me especially when you put MP3s on it. I don't know but if there weren't any MP3 files, the sd mounts quickly in MTP mode.
But if you wait awhile the sd mounts in MTP. Even though at first the Play is detected but no memory card.

Uhm... how much is a while?
I remember waiting for as long as 10~15 minutes.
Also my SD has no media on it besides the game files a couple of ringtones in their proper folders and so.

Try switching from MTP to MSC them back again while the USB is inserted. It's a tedious process but it works with me. Otherwise, do a pc companion firmware repair.

I've got the same problem and I've long ago abandoned the idea of fixing it as I tried lots of different tricks but nothing really worked.
So now I just use it in MSC mdoe.

ICS ROM
I got tired of this and some other issues with Link2SD and finally flashed an ICS ROM (Darkforest ICS, based on Sony's official ICS beta).
The ICS' implementation of MTP seems much better than the GB one...
The only thing I kind of miss is the frontal camera .

[Q] HELP: any way to enable the mass storage mode on the galaxy note 2 ?

can any one help me and suggest a method to enable the mass storage mode in my note 2 , when connected to my laptop ?

Firstly why? MTP is better when you get it working as you don' t need to unmount anything from the phone first!
Secondly, it is likely to be possible yes probably very similar to how it was hacked to work on the s3, however it only worked for external sd and caused lots of corruptions to sd cards... so it is far from perfect.
My advice would be to get used to MTP.

i was need it to let my stereo car read mp3 files i solved by installing an s3 hack that can make the extsd a mass storage unit take a look here http://forum.xda-developers.com/showthread.php?t=1711009 it worked for me i'm with omega v4 rom

I understand what you mean but. ..it becomes virtually impossible and frustrating to transfer stuff to internal memory or even external memory because it is slow. ..Very slow
External memory I can manage by taking out my card and using an adapter to plug it into my laptop card slot..
Is there a way to mount internal memory as usb mass storage? I don't mind if I have to turn my phone off or something

Did you try Airdroid?
Sent from my GT-N7100 using xda app-developers app

try Kies over wifi...
it transfer data using local connection and transfers GBs of files in some minutes definitely MUCH faster than MTP and prefer it to AirDroid, but it hasnt been working lately (last time i checked was a week or two back)

This is a problem for those like me using Ubuntu. I never managed to make MTP work on it.
Wi-Fi transfer of files can be done with X-Link, but the lack of mass storage is a nuisance.

Yes, MTP is a big problem on Ubuntu. I have tried 3 implementations of MTP protocol on 12.04 and 12.10, no dice.

i'm searching for an answer. worst thing with mtp is the fact that it hides directories from you! so you can't backup everything properly. annoying

bump! MTP is too/painfully slow. Reminds me of 1995. We need an alternative. Whoever put up this technology without due consideration and testing, before deploying it on these popular devices needs to be consider a different job.

looks like I wont be getting this phone until mass storage mode is added

Unfortunately, there is no way to enable UMS mode without rooting the phone.
I had to find a solution for my car stereo be able to read mp3 files.
I just rooted the phone and install SGS3 easy UMS ( PlayStore ). Yes its working just perfect on NoteII.
I'm using Ubuntu at work and it works like a charm as well.
Don't forget to unmount the drive in Ubuntu before unplug, and stop the service on Windows.
Also, on the UMS app, switch back to MTP before unplug, to avoid files errors ( no problem if u are just reading, ie: car stereo)

Hello,
one question - how to make two-way sync folders between my laptop and SGN2?
I always did it with GoodSync, but now it is impossible...
thx

Haha isn't this a cool icon? ---->
Gah.... I was hoping there was a way to USB mass storage on this phone. I guess I should have done more research on the phone before I bought it. I'm still in my 2 week return it period, but that's not THAT much of a deal breaker. Just really stupid... Why can't I have it all?? I mean we finally got USB host (OTG or whatever; same same) from a stock phone, only to lose USB Mass Storage! Oh the frustrations!
Dramatics aside, will a custom ROM allow something different? I'm not clear on what layer this MTP mode is operating at. I did think it was funny that it popped up as a camera type device in Windows. Right now I'm only using internal flash. Usually I want to browse pics on the phone from the PC, and in this case, if I use IrfanView to open one on the device, it copies it local and then opens it, so I can't scroll through them. Silly, and mildly frustrating. :-/
I'm going to look into some networking options to see if those work (Kies, AirDroid, maybe FTP). Actually, Dropbox might solve this particular problem for me now that I think of it.
I saw the thread for mounting external SD as USB mass storage. I take it there's no way to co-mount the internal storage as a USB mass storage device?

Well, Samsung turned off the USB Mass Storage for obvious reasons. But anyway, I can access both memories from my computers, using MS Windows.
On windows, there's no problem at all as you can manage all the files directly from explorer.
On Other systems, the problem is different. For some reasons, like with all other systems (ie car stereo or media player...), the galaxy will not be recognized because MTP needs drivers. Then, you have to use UMS and the only way to install and use it is to root the phone. But keep in mind UMS will only permit access to external memory card.
Well, if I have to transfer files from internal memory through UMS, I copy the files I need to external memory before using it..... That's not a big problem , is it ? And because your phone is rooted, you can even find a script to copy some folders automatically.
Hope I'm clear enough and it helps.

What I really really hate about this phone? No native USB support

The usb storage. MTS or whatever you call it . Very slow, terrible for navigating/editing multiple directories/windows at once. Frustrating. Can only find size of files by going in the directory and selecting all files. Anyone know of a good quick solution to this? I've played with the common game editor but don't really see it as encompassing the solution to all the problems of not having the classical USB mount

You think thats bad? Try having Mac. I can't even get it to recognize me phone lol. I'm forced to used my windows machine.
And I believe its a JB thing, not necessarily Samsung.

I had this problem too with my macbook pro then I found a solution tonight. Try this:
1. Install Kies if you haven't already, if you have make sure it's updated.
2. Connect your phone.
3. In Kies, click Tools, then Install Drivers (this will reinstall drivers
4. Download Android File Transfer.
Should work after this. Also make sure you have USB Debugging on and use PTP not MTP.

I will be sure to give this a shot tomorrow and send along an update. I rarely use Kies, updated it yesterday but never tried the drivers thing. Android file transfer never used to work but maybe the "install drivers" step is all that's needed.
And thats why I love it here on XDA. Thanks for the help brother!

I agree... coming from a s2 skyrocket, I really miss UMS. Why bother having expandable storage when it takes hours to transfer to a class 10 32gb sd card? That is if I can get it to transfer at all.
I'm now resorting to unmounting sd card and putting it in the computer to transfer files...big PITA
SGS3 Easy UMS doesnt work either.
Edit: Actually, I'm using kies now... still miss drag and drop

Agreed. Always had driver problems with this phone. Sometimes it wouldn't connect because drivers failed to install or "bad hardware ID" pops up in the corner. Only way to get it to work was to restart comp. And it would only work until I disconnected it, then gotta restart again. -.-
I'm gonna switch back to linux once I get some free time. I recommend you do the same.

It was a problem in ICS as well. I think the reason for that they went with MTP is that users would create a "messy" file structure when they randomly dragged and dropped files anywhere on both the internal and external card. Samsung can keep things organized when they encourage you to use Samsung Kies to add files to the device.
The mandate for MTP is also to reduce piracy of protected media files by ensuring the DRM is properly done. In the past, I could connect my phone directly to my Samsung SMART TV and play 720/1080p movies via UMS. This is now blocked with MTP.

Thanks I also noticed the slow data transfer speed when I upgraded my SII to S3. Thought it was something I was doing wrong. I've changed the default transfer to PTP and will check it out tonight.

Don't bother with PTP. PTP is just a camera. It's not like UMS so you might as well leave it on MTP

I was annoyed by this as well. Now when I want to add something to my sd card I just take it out of the phone and put the sd card in my Mac and add files that way. It's a little annoying but its not that big of a deal.

I think the closest you'll get to a true UMS experience is using Samba Filesharing Server (https://play.google.com/store/apps/details?id=com.funkyfresh.samba). You can then treat it like a network shared drive.
Of course you'll be limited by your WiFi speed. I think a possibility would be a USB host adapter and a USB ethernet adapter. I'm not sure if Android has support for a USB ethernet adapter but if that works then you should be able to connect to a gigabit switch/adapter and just be limited by USB2 speed.

It's not just this phone in general. They're all going that way as of ICS (Honeycomb as well) and up. If you use Windows it's not terrible but it is still slower. And yeah trying to use it with my Mac or even my Linux box is just frustrating. The primary reasoning was to merge the data and application volumes to give more space for applications. This is a better explanation of it. I do miss USB storage mode though.

Yep, totally frustrating for me also.
I remove my microSD card when I need to do lots of file management. But it's a clumsy workaround.

[Q] My Nexus doesn't connect to the PC? Help?

Just came back from holiday so I've got some pictures to store on my computer, but I can't get my phone to connect to it. It charges fine when connected which is also bemusing, since it can't do anything else. It's definitely not my computer's problem as I've tried other computers to no avail. I've been looking around the internet but none of the solutions worked for me.
My Nexus is rooted with stock ROM on 4.2.1 Jelly Bean and hasn't had many other problems in it's lifetime, although sometimes when I go into the Gallery app it will tell me "No external storage available" and I cannot use it until I restart the phone, where the problem diminishes and reappears after a few days. I was wondering if these problems were linked in any way perhaps?
Thanks for any input guys, would really appreciate it

You tried a different USB cable? Just a thought...

Is USB fast charge enabled?

I had the same problem - turns out it wouldn't connect on my PC's front USB ports, but does work on the rear ones.

first be sure that fast charging is disabled, second try other usb port if not try other usb cable if not try another computer, if not...i dont know!

Maybe usb-debugging is on and your PC has a driver Problem with usb-debugging?
Else: Go to device management and look if the device is properly shown also galaxy nexus.
Else2: I don't know. Maybe open the window and throw your PC as far as you can

That cannot be the issue. I did not have USB debugging enabled but I was still able to transfer the files. But, you can try re-installing the Google USB Driver or Samsung Driver for I9250 or was it I515?
Cheers

Check on computer that device is showing in devices and has correct drivers installed. If not samsung official manuals and downloads website (google it) has a driver pack (approx 30mb) which when installed should have every samsung driver you could need, download and run then reboot computer and plug in phone, all drivers needed should now install correctly.
Also check in usb options when first connected that mtp is checked so storage is visible to computer. Best of luck and if all else fails pc out of window sounds like fun
P.S. try flashing latest gapps to fix gallery issue, after dalvik and cache wipe, may solve gallery issue...

It will be shown as mtp device but not usb mass storage...he wants to mount the internal and maybe external sd card as mass storage like you would plug the usb flash drive to pc/laptop...but there is at the moment no way or method/workaround to get it working...but mtp should work on this phone fine so that transferred files shouldn't be corrupted etc

Why? So the phone and computer can both access the storage at the same time so apps don't FC when you use mass storage. It's been like this for 2 years now so a bit late to be getting angry!

It would be nice if you could have the choice between the two. Sucks I can't hook up to my car's media interface.

In http://forum.xda-developers.com/showthread.php?p=54035979 I may provide a partial solution; depending on your exact need. Look for the post I sent a few minutes ago. More to come in the next days; I will test other apps, and report.

People that have problems probably don't have good drivers setup for their phone. I think the last time I had issue with mtp was note2 and I updated my Samsung USB drivers and all was well. Have pretty much done that first thing when I get a new phone now. Never had problems with nexus 4/5, note3, moto x and now HTC m8.

Driver issue ... on desktop side ?
There are MTP issues on phone side, and this is not driver related. On same hardware version, you can find a veriety of stock ROMs, with a veriety of behaviour.
Plus there is a specific case where MTP deeply sux. If you read ads about M8 on HTC.com, you will see ... this phone is wonderfull because it can read UMS devices. Now, use this to connect two M8 together ... nothing happens; because whatever you do (with your OTG cable), M8 will provide MTP, and expect UMS. So, in short, this phone is not even compatible with itself !!!
So, the question is not to know if drivers have been installed correctly on desktop (Windows, Linux, Mac, whatever you like ... BSD, QNX, Solaris, OpenVMS ... just to quote the ones that can boot withint 2m around me ^^ Oh, forgot my Octane; it's 3m away). The fact is that MTP sux; and in many case, UMS is a must have. OTG was one example (wired phone to phone);similar example would be phone to tablet: you need at least one device to perform UMS; if both are MTP only, you are stuck.
Some M8 do UMS with stock ROM, others don't.
In my thread, I gave alternatives for MTP and UMS.

Like I've said my problems have been few. And if I do need to connect phone to phone I prefer WiFi direct or Bluetooth. And I rarely hook my phone up to my laptop anymore. I use WiFi file transfer pro. About the only time I use it it to do my initial load up of 50-70gb+ of FLAC/mp3 more so because my phone won't lose charge while doing the massive transfer overnight. Then as I need to update or sync files I just use wifi file transfer pro to update. I don't see what the big deal is for PC's and such. But I do understand for use cases as car audio, the rare need to do phone to phone transfer because one/both users are less familiar with wireless transfer and I am sure there are more that I can't think of now. You would think somebody could've made an app that merged a file explorer and tricked os into doing ums, at the very least with micro SD cards. Internal would definitely be trickier and probably a lot of phones would be left due to the masses of different phones, skins and frameworks. I dunno. Hasn't been a problem for me at all really.
