General :: MicroSD Card Read Only After 4.3 Update Of Google Edition Samsung Galaxy S4

Aug 6, 2013

Earlier today I got an OTA upgrade of my Samsung Galaxy S4 to Jellybean 4.3.

Everything is working great except for some reason my external SD card (A 64 GB SanDisk MicroSD) is read only. The only thing I can do with it is to format it. Otherwise all write operations to it fail.

I have tried two different cards and several different apps (Terminal, Astro File Manager for instance) and none of them can write to the device.

I am almost thinking it is a matter of a missing new permission but I can't find anything in the SDK docs about it (If this is the case that is fine because my main use of the card is a home made music player that I've written).

Motorola Milestone :: Max Read/write MicroSD Speed Supported

May 14, 2010

What is the maximum read/write microSD speed supported by the Milestone? I couldn't find information on this anywhere.

I am not sure if it's worth spending the extra money for a class 6 (8MB/sec) 16 GB micro SD card vs a class 2 (2MB/sec), as I'm not sure the Milestone will support it.

Android :: Read Data That Been Separately Copied To Sd Card Without Having Root Permissions?

May 4, 2010

I am developing an application that needs to access data on the sd card. When I run on my development device (an odroid with Android 2.1) I have root access and can construct the path using:

CODE:..........................

However, when I install this on a phone (2.1) where I do not have root access I get files == null. I assume this is because I do not have the right permissions to read the data from the sd card. I also get files == null when just trying to list files on /sdcard. So the same applies without my constructed path.

Also, this app is not intended to be distributed through the app store and is needs to use data copied separately to the sd card so this is a real use-case. It is too much data to put in res/raw (I have tried, it did not work).

I have also tried adding: <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

To the manifest, even though I only want to read the sd card, but it did not help. I have not found a permission type for reading the storage.

Android :: Can Custom Read - Write Permissions Effect User Acceptance Of An Application

Apr 29, 2010

I have two published apps that are pretty targeted to the user collecting their personal medical data (like Blood Pressure, etc.) and then, eventually sending it somewhere, if they choose.

I decided to put Read/Write permission on my ContentProvider, so if another app comes along that wants to the access that content, the user will be warned. The permission that is required is declared in my apps.

When the user installs my apps, they are also given a warning that the app requires that permission (even though it's the one that declares it), and it shows up in the Marketplace also.

The question is: Is it possible that the permission acceptance part of installing my app could be putting customers off? I don't know what other's acceptance rate is, but mine is around 50% of customers who download it have active installs.

General :: App Update Permissions - Any Way To Restrict Permissions?

Jul 23, 2012

The permissions say that you must agree to allow them to delete files from your storage including your SD card; must agree to allow them to extract any information from your phone, etc. In other words they can do any thing they want with your phone and the data in it.

Is there any way to not grant these permissions and still get updates?

Android :: Android Permissions - Calls Read Phone State / Identity?

Nov 17, 2009

My android app has nothing to do with phone calls, but I'm seeing that when I install a debug build on my test device it requires "Phone Calls: read phone state and identity" permissions. (I make no mention of this in AndroidManifest.xml). I'd like to have the minimum possible permissions, and wondered if anyone knew how to get rid of this? I commented out the part where I was logging some stuff from Build.MODEL, Build.VERSION.*, etc. I also commented out the part where I was detecting the landscape/portrait orientation thinking that that might be the "phone state". But neither of those seemed to remove that permission required.

I found this bug report but it's marked working-as-intended with a note about permissions being correct from the market but not otherwise. Is this other people's experience? (I'd hate to have to publish to the market just to test that out.) Otherwise, does anyone know if there's an API I can avoid calling that will make it so my app doesn't need this permission?

General :: Transferring Games And Apps To New MicroSD?

Jun 8, 2012

I have a rooted motorola atrix 2 since I'm not sure if it's the same for all androids or not.

I've been using the 2gb microsd that came with my phone til now, but I'm out of space so I had to upgrade. All my apps and games have been saving onto the sd instead of my phone since day one(not sure if this can be altered). I need to know how to transfer all the apps onto my new microsd card without having to reinstall them all after switching.

Also, I edited the build.prop making the phone thinks it's an optimus 2x(I think thats the name of the phone) so that I could play Order and Chaos Online. Not sure if that would change anything needed for this task.

General :: Recovering Files From Corrupted MicroSD

May 24, 2014

I bought a SanDisk Ultra 32gb microsd card to use it with my Galaxy S4 GT-I9500 several months ago, I've been using it with no hassle for a while now. Few days ago, my device stopped recognising the card, as if it didn't even exist. So what I did was insert the microsd into my laptop using an adapter, and I could see all the files intact and safe. The problem is, I cannot copy the files off the card, it's like it keeps disconnecting every about 10secs, once a copy or move operation starts, it goes about 10% and then stops, forcing me to cancel the operation, and sometimes it doesn't even start. The files are there, i can view them, i just cannot copy them. I want to copy the files off in order to format the microsd card to be able to use it again.

Another major problem is, files and complete folders are disappearing! I lost my photos folder and all my music folder (luckily i have a backup of those).

I have read somewhere that SanDisk manufactured faulty 32gb cards, and i get to return it and get a replacement, but i bought it from Amazon and i shipped internationally, it will be very cost inefficient to return it. GT-I9500

General :: MicroSD Will Not Save Anything Correctly Since Partition

Apr 15, 2013

My SD card won't save anything correctly (pictures, apks, Roms, etc.) since it was partitioned. The oddest thing is that some things will save correctly, but very few. Everything will save, but when you try to open something, the phone says it can't be opened. When I rooted my Motorola Atrix 4g, it forced me to partition my SD card. I don't know anything about modding and I just followed online instructions to root my phone. I don't remember exactly what was going on, but my phone wouldn't work until I partitioned. I used ROM manager to partition. Anyway, I was thinking about formatting my card, but I'm afraid my phone won't work without the car being partitioned. So, I was also thinking about partitioning again. What should I do, and why is the card acting this way?

General :: MicroSD Card - Unable To Add Files On It From Laptop

Jun 10, 2013

I have a 16 GB SDcard. I have used it on my Samsung Galaxy Ace for around 8 months now and it has worked fine. Today I when I tried connecting it to my laptop to update my music I faced some problems.

My computer detects it and displays all files, but I am unable to make any changes to the the folders/files i.e. delete, cut or copy new files onto it. I was also unable to format it. So I formatted it via the phone itself and tried it on my laptop again. I am still unable add new files to it. However, it works without any problems on my phone.

Since I do not have my the USB cord, I am using a Samsung Micro SD adapter to access it on my laptop.

General :: Note 2 - Apps Can't Detect MicroSD Files

Dec 13, 2013

I have a problem on my galaxy note II GT-N7100, running Paranoid Android 4.0 beta, android 4.4.1

Ever since I've upgraded to KitKat, some of my apps don't detect data on external micro SD card. Most noticeably quick office, the bards tale. As most of my files are stored on micro SD this is very annoying. I can access those files using es file explorer but it would be better if apps could detect them as well. My external SD card pathway should be mnt/media_rw/sdcard1 but that's empty and I get invalid file path error.

I can access the ext sd by storage/sdcard01 though. I've tried to format my ext SD, edit platform.xls etc but no solution. So any clue how to make quockoffice access documents on external micro sd?

General :: MicroSD CARD Partitioning Causing Crash

Whenever I insert my sd card into windows via my phone, it asks me to format it. Why has micro sd partitioning wrecked my sd card???!!

General :: Recover Encrypted Photos From MicroSD On LG Spectrum VS920?

Jan 20, 2014

I recently had a problem with my LG Spectrum that required a hard reset to restart the OS. I wasn't aware the photos were being encrypted. When the reset was done the phone required I enter a passcode. I entered every known passcode I have and still could not get the phone to recognize the photos on the microSD card. Is there a work around for this process? I have over a years worth of pictures on the microSD card. The LG Spectrum model is a VS920.

General :: Moving Apps To MicroSD On Samsung Galaxy Rush?

Jan 1, 2013

I just bought my micro sd card (8g) and I inserted it into my phone. It says its there but I don't know how to transfer my apps or music, videos, extc onto it! I have the Samsung Galaxy Rush. I tried downloading apps to move it but it says there is an option 'move to sd card' and there isn't. Is it not reading the micro sd card right? I tried moving simple apps, messenger, bubble worlds, fruit ninja, whale trails, things like that but all it said was clear cache and no other options. I downloaded a few of these apps to transfer to the sd but they didn't work. I don't really know what to do because it says I have little space but the sd card is in there. It has 7 gigs of space but nothing is on it. How do I transfer my apps?

General :: Swapping Internal Memory With MicroSD Bricked The Phone

Apr 15, 2014

So recently I got lack of internal memory(it is only 512MB though) and I tried to swap internal memory with microSD(marked as sdcard2). However, Im noob in this and after changing the lines I understood, that I changed sdcard with sdcard2(swapped sdcard and sdcard2), however, my android system seems to be not working now. I can boot and access settings, but thats all. No menu, no apps, no anything. Empty screen, only settings accessible. I cannot access any files or anything...

What I tried:

- Connecting phone to PC as I have Android Commander program which can browse system files from pc, unfortunately, failed to connect.
- Factory reset. Didnt work.
- Recovery mode - tried all options that are available, didnt work.

The phone is Prestigio Multiphone PAP4300 DUO. When I boot to the phone, I unlock it and I get many messages saying com.android.phone, system and such things stopped working. When pressing HOME button, it goes to home, but its empty(empty screen) and tells Launcher stopped working too. All I can do is access the settings. Cant call anyone though.

What to say to warranty service when I will bring the phone to them. Can they recognize that its rooted/that the vold.fstab file is modified?

Specs: [URL] ......

That looks to be white, but mine is black. I rooted it only. Havent done any changes to the phone until yesterday - swap the memories.

General :: Attempting To Salvage MicroSD Card Pics / Videos?

Nov 7, 2013

Samsung Note 2. 16GB Samsung SDHC card. Not rooted. Stock ROM. The other day out of the blue, pops up and says "SD Card Blank/Unsupported Filesystem".

Attempting to put SD card in other phones = same result.

So trying to get it to connect to a computer. Yes, the adapter that I have supports SDHC cards.

Trying to run command prompt and it's not seeing the pathway to the drive (F.

Here's what's interesting to me...If I go START>COMPUTER>RIGHT CLICK>MANAGE>COMPUTER MANAGEMENT>DISK MANAGEMENT...IF I have the SD card connected to the computer, then that box freezes right there and stops responding...If I disconnect the SD card, box automatically pops up and shows the hard drives on the computer. Plug it back it, that box stops responding again.

Another intersting note...Now AUTOPLAY is attempting to pop up and run...it keeps running the bar back and forth like it's attempting to read, but then it just disappears. If I go to MY COMPUTER and look, I can see the F DRIVE there...but when I attempt to click on it...It just freezes that box as well, stops responding and I have to force close it.

With the AutoPlay kicking on and MY COMPUTER recognizing the F Drive, that leads me to believe that the card itself isn't 100% toast and recoverable...Has the controller module on the card gone out?

And FWIW, I have tried getting the card to read on Windows XP, Windows Vista, Linux and OS-X...The AutoPlay that it's doing now is on an XP machine. Obviously, I can't attempt to salvage any files if I can't get the computer to atleast recognize (and continue to recognize) the card.

General :: Apps Permissions After Uninstall

Mar 11, 2014

When installing a app (after confirm its permissions) - the persmissions like "contact", "calls", etc (all kind of permissions) - are disabled to the dev once I delete the app or he always have access to my info (at permissions) OR at the time I've download the app he have access to the permissions until I delete it and all the permissions are disable?

Usually this information/permissions are availabe to the dev automatically once I install the app or he need manualy to get into this informations? If I force stop the app, will it still have access to my data (permissions) or only if its running?

General :: How To Set Permissions With Updater-script

set_perm(UID, GID, mode, "pathtfile");

I know what UID and GID stand for, but I don't know what to put in the "mode" part. run_program("sbin/chmod",) will do the same task, but I don't know how to use it xD. I know how to use chmod though..
