[Q] App2SD working but apps cannot access SD Card - Android Software/Hacking General [Developers Only]

Hi,
I have a weird problem that only happened days after I installed App2SD. I used GOT Open Recovery to format my SDcard and installed App2SD, but not knowing which version to install, i installed both the normal one and the symlink one.
I proceed to install all my apps and such and everything is into the SD card. Then just today, I found that my apps cannot access the SD card. Such as the camera, even titanium reports that no card is mounted. Under settings>SD card, there used to be a value but now its shown unavailable. But if I used astro, i can access the sdcard and launch stuff from it with no problems.
I can even connect my phone to my PC and see the SD card contents using SD Share.
I tried to reinstall App2SD using the GOT Open Recovery, but unable to. It'll hang there. for both versions, with and without symlink.
May I know what is happening or what can I do to enable my phone to see my card? Can I issue commands using terminal on my phone? If so, may I know what commands?

How to move Amazon MP3s to External SD?

I recently bought a 16GB card for my G2X, and I started downloading more of my music directly to the phone. The problem is, I can't seem to figure out how to move my music to the External SD. I tried to use Astro, but when I selected the Amazon MP3 folder and tried to copy it to the External SD, I got a move error.
Now that I look further, I can't seem to do SQUAT with the external SD. I see it listed in SD and phone storage, but I can't move anything to it with Apps2SD or with the native GB app manager. Am I just missing something?
Are you rooted? If so, try using a Root File Explorer, such as SUFBS or Root Explorer.
I am not. Do I really need to root to use that external SD slot?

No, but I just figured, you'd be able to have SU Access, hence, more permissions in Android to move files.
Just try a different file manager from the market. I always had trouble with Astro when moving files to the external sdcard. Anttek File Explorer and Super Manager are two good ones and they're both free.
First thing you do is unmount you external sd card in the sd card settings of the phone and then take it out right away after it says unmounte dof corse then reinstall it and wait till it is done scanning it then see if that works. If not then I would try a different card one that you know works in something else and also try that on in a different device like your pc and see if it workes there this way you can determin if the card is broken or if the phone slot is brokem and if the phone seems to be broken I would try a factory reset.
Thanks, Phburks, I tried Super Manager and that seems to be moving it just fine!

Stock UCLF6 writing to external_sd not working

I updated to ICS 4.0.4 (UCLF6) using CWM. I just noticed I am unable to make changes to external_sd. Initially, I was using an app to move installed apps to the external sd. Then after a reboot, I noticed my phone would say those apps were not installed. I also tried copying a file to external_sd using SSH/SCP. Everything shows the file there. In the past, the media scanner would kick in an run right after but it does not run.
Anyhow, after a reboot, the files I just copied are gone as well.
The 2 issues leads me to believe that writing to external_sd is not working.
Anyone else seen this issue? Are you able to write to external_sd and not lose the data after a reboot?
Phone is rooted.
SD card faulty?
You might check to make sure your SD card isn't faulty. I had a similar problem and I couldn't even write files or format the card from a PC. Ended up getting it replaced under warranty.
If you connect to a PC and are able to write files to it then I'm not sure what it could be.
Possibly but very unlikely. I upgraded to ICS from GB using zip files that I placed on the external sd. I suppose I could try and revert back to GB to confirm the external sd still works.
What I will do next is to copy all of the data off the external sd and reformat it from CWM. Let's see if that works.
The odd thing is I am able to write/delete stuff on the external sd. There are no errors in such operations. However, if the phone reboots, then all changes are lost.
It's almost as if the entire external sd were mapped to and running from memory. So you can apply any changes you want but they get lost when the power goes out (ie. reboot).
It seems I'm the only one seeing this issue. Have not heard anyone else seeing the same.

[Q] Error installing app Can not install USB storage or SD card

I recently updated my external SD card.
Transfered all the information from the old one to the new one, VIA Windows PC.
Seems like all went fine until I went to one program I thought was installed PPSSPP
Seeing as it wasnt showing up now I tried re-installing it.
Now with the play store it says after downloading that the app
Could not be installed on USB storage or SD card.
Looking at troubleshooting here is what I did so far.
I did look for the file smdl2tmp1 and did not find it anywhere.
Unmounted the SD and rebooted , install of PPSSPP and says same error.
Removed SD and booted , still same error on install.
Dirty Flash Rom.
loaded Rom Toolbox lite and changed app2sd location.
Same error on everything I tried.
The only thing I can come up with is that there is a file that is causing problems that I cannot find where it is.
Any suggestions without doing a full flash and reinstall?
HTC EVO 4g LTE
Carbon Rom 4.4.1
Any thing to help is greatly appreciated
Update tried downloading and installing another app and getting same error , on something that I never installed before.
Update 2. Wiped SD internal and external , did not work. Same error

are you sure the SD card is not fake? for years now, ebay fradulent sellers peddle 4gb cards with a 32gb filesystem. After going over 4gb, the files are just copied to dev/null, but their names are still present in the allocation table
so plug your card to a computer and check it with any flashdrive utility
If you are unable to write in the external sdcard using a file manager too then - back up external card's data, connect to windows pc in usb mass storage mode and format it in fat32 format.
It should fix the issue.

This happened with the origional 32 GB card, then I did put a FAT32 64 GB card in the phone. Moved data over to new card.
It reads in windows fine. and both are fat 32.
Also tried installing without card installed and gave same error.
Titanium backup files will not reload, and even some amazon ones wont, but updates do most of the time.
Another thing I noticed is that my internal is GB for apps, that has about 300 MB left. I think this may have something to do with it so moved data over to SD.
Just tested about 3 restarts and finally went with a paid app, Tried changing default install to auto , internal and SD. didtn really make a difference.

[Q] SD Card not writable

I went to Wal-Mart and picked up a 64GB SD card. I just purchased the tablet yesterday and rooted it using towelroot but that's all I've done. I put the SD card in and it's recognized and showing the correct available space. I'm able to create a file using ESFile explorer but I can't do anything with it. I tried a couple torrent clients to download files to the SD card and it keeps saying unable to write to folder or that it's write protected. When in file explorer I can create a file and under properties it does show it's able to be written to. I also have downloaded and tried the kitkat SD card fix app. I've gotten pretty frustrated with it so just did a complete factory reset and going to start from scratch. I was able to move apps to SD card using an app but that's all I could do. I'd really like to put any/all downloaded apps and files on the SD card since I only have a 16GB version.
Any ideas what I can do?

Well just an update after doing a factory reset everything seems to work now, of course i get to download everything again. I think it might have had something to do with the OTA update. After doing the factory reset it kept the update. Now I can freely move to and from the SD card so all is good.
FYI, since you are rooted I would suggest installing the Xposed Framework and then install the "HandleExternalStorage" module, the KitKat update cripples external SD card access so file managers, emulators, and the like can no longer write to the SD card. Installing this module re-enables external SD card read/write access for all applications, it is not the device. There is also an app on the Play Store call 'SDFix: KitKat Writable MicroSD' which accomplishes the same thing, however the Xposed module is much safer as it can be enabled and disabled at will. Simply install the module, enable it, and that's it.

[Q] Problem moving apps to external SD card on SM-G355H

Hi all,
On my 4.4.2 Samsung SM-G355h, and since few monthes, i could no more move any of my apps to the external SD card.
These are symptoms:
One folder on the SD card, called Android, can not be deleted, no matter what's the way i try to do it (directrly from the phone, from computer through USB, putting the SD card on other phone ... )
Some time, I could not delete nor move any file on the SD card. I have to restart the phone, and to do it on the first few seconds of the system start up.
On the apps list, and when i look into the apps proprieties, the system could not get the size of the apps. It remains "loading"
When i try to move an application to SD card, the system remains hours with the indication: "moving to SD Card" and nothing happens.
I have tried to reset my phone and then download and reinstall all apps. Same problem.
So, can any one tell me how to fix this problem ?
Thanks

First it could be update related/flash related.
Some versions of stock firmwares contains weird "bootloader" stuffs that prevents rw access to sdcard even if u install the sdCardFix for KK. Sometime it works sometimes not.
And the second is you have to have SdCard KitKatWorkground enabled.
Check : http://forum.xda-developers.com/galaxy-core/help/copy-to-ssd-samsung-galaxy-core-2-sm-t3033178.
The /Android folder on extSdCard contains /data and /obb files that have been moves/installed to sdCard, if u delete the folder, U won't be able to run the app from your phone !
