On Ice Cream Sandwich, I used to use an app called DS Super App2SD but it doesn't work on Android 4.3 Jelly Bean. I'm using Samsung Galaxy Tab 2 running on Cyanogenmod 10.2 nightly (Android 4.3.1) I already tried the adb shell pm set-install-location to SD card location. It made everything worst by thinking my empty 32GB micro SD was full. So I set it back to 0.

After I got my phone restored from an nandroid backup, I found almost all apps cannot gain access to /sdcard/ (internal storage), including ES file manager, Z archiver and so on. When any of these apps access /sdcard/, or any other equivalent folders like /storage/emulated/0, /storage/emulated/legacy, /storage/sdcard0, they only shows a blank directory, and I cannot create any file or folder. When I try with the stock file manager (My files), it does show the files, but i cannot rename, edit, or create anything. Android File manager is able to copy most of my files out. But It stucks when I try to create a folder or send something. I tried to re-flash the same ROM again (which worked perfectly before), the issue remains. I have backed up important data from /sdcard/. In terminal emulator, cd sdcard, ls gives opendir failed: permission denied. Then I tried su, ls shows the correct directory. How should I fix it? Extra: I found a new folder called knox-emulated in /storage which is not there before. External SD card (/storage/extSdCard) works fine. Device Information: Samsung Galaxy Note 3, Android 4.4.2 Rooted, with a custom ROM modified based on the Stock ROM. Custom recovery installed.

Is it possible to edit the fstab to mount /data, /cache, etc. from a different partition on the 1. internal memory? 2. external SD card? Details: The default partition for /data and /cache is too small for my needs and I can manage to format the (internal) /sdcard in ext4. My question may superficially seem to be like other questions asking for a way to increase the size of /data, but it's not. Here's why: 1. I need to do it *specifically* by editing fstab, which is the usual way of doing the same thing on a GNU/Linux desktop. 2. The other questions don't ask about /cache and other partitions.

I used a micro SD card in a Nokia Smartphone for years as internal storage. I ejected it to test if *another phone* detects this type of SD card. Although we planned to just see if it is detected, certain off-topic factors led to the acceptance of Google's suggestion to '*format it as internal storage*'. **As long as my phone still remembers the decryption, is there a way to recover** my Photos, GPS-tracks, Text-Notes and other data, despite being *encrypted* with the known key *and formatted* by another phone? ---------- My assumptions: * data from a non-encrypted card can often be retrieved mainly because the raw data still 'looks like' photos, mp3 etc; * encrypted data doesn't 'look like' anything, so recovery tools won't find anything; * Even if my phone doesn't care about data parts but about some 'yes I am your encrypted storage do not format me' file, a recovery tool would need the *decryption information* to look for the original content (i.e. *how to extract it* from the phone plus tell the tool?) ---------- Side note/non-duplicate: Similar questions that I found always have somebody losing the decryption key and I agree that recovery should be impossible in those cases.

I integrated my SD card to use as phone memory. Everything was fine until a couple of days ago. All of a sudden I saw the "insert SD card" notice appear on the notification bar. I open the back cover but the SD card looked like it was in place. I remove it and insert it back and then I formatted it as external then the notice disappears. But then I notice that when I go to file explorer (FX) to access my files, it doesn't show anything like the internal storage doesn't exist, crashes my settings when I click storage. I can't access anything that is on my phone memory, although the apps are working. I guess system files are okay. My device is not rooted and it seems the only thing I can do now is to format my phone..I don't want to go that route please.

I am using the adb shell command to access either an LG P690 (device A) or a Samsung Galaxy SIII (device B). Device A also has a 32GB microSD card plugged in while device B does not. When I cd /sdcard and do a df from the shell prompt, I get: - On device A: /sdcard Size 14G Blksize 8192 - On device B: /sdcard Size 12G Blksize 4096 Does this refer to internal memory? Device B also has a /storage directory which holds 0 bytes (what is this?). Also, both have a /data directory which I know is where installed apps go. Is this also on internal storage? How do I know whether /data is on internal or external SD? I'm confused as to why a directory called /sdcard would refer to internal as opposed to external memory. Is there no FHS standard for the Android file system as there is for Linux?

**Problem description & Background**: My phone suddenly stopped storing or retrieving files after I swapped the 64Gb SD for a bigger one - 1Tb. I cannot access Settings/Storage to query, eject or reformat the SD. Files shows zero bytes in all categories except Apps, and I cannot download or update any apps. I removed the 1TB SD and replaced the 64GB, and I have tried with no SD at all, but the damage was done. **Question**: Can I get back to the "good" card? Or do I need to "Factory Reset?"

I have a Samsung device of 8GB with an SD card of additional 32GB. I'm using many apps that cache data for offline use (mainly Google Play Music ), these apps are not smart enough to determine the 32GB of available space and take advantage of it, but instead claim 'no space'. I thought perhaps there is a workaround for it by merging the external storage with the internal so the apps 'think' there is 48GB. I don't use several SD cards which means I'm not gonna switch SDs back and forth any time soon. Do you know a hack for it? Or any solution to make Google Music store its stuff into all available space wherever it is? I've read [this](http://forum.xda-developers.com/showthread.php?t=1251896) link, but since I'm not so much into Android development, I didn't understand it, can anyone refer me or translate it into a more detailed guide (I'm not a complete noob, but I'm not a hacker). P.S. My device is rooted.

I am trying to do a full copy of /sdcard of my unrooted OnePlus 3T to my Windows PC. So far I've tried: - adb pull /sdcard/ C:\mylocalfolder\ Works OK but as soon as there is an error it stops the process, so the copy process has been truncated. The error is due to a file containing a colon ":" in the name, so it can't be copied to Windows. --- - adb exec-out tar c sdcard > sdcard_backup.tar Doesn't work, it stops immediately and creates a corrupted 4kb file. --- - Copy the files using Windows via Data Transfer mode Windows halts calculating time to copy files. --- Adb pull would be the ideal solution so far if is there a way to skip/ignore errors so it can continue copying the files, or perhaps try to skip the files with certain characters. I've tried both Adb version 1.0.32 and 1.0.41 (latest version as of July 2020). Any suggestion?

I am familiar with computers. With computers, we have BIOS. BIOS is something like memory and hard disk. It's attached to the motherboard straight. It is, for all practical purposes, like a hard disk. When we boot the computer, I bet the BIOS would start first and then we move to the operating system. Then we got the real hard disk. We can reformat the hard disk all we want and the computer will still be useable (not bricked). That's because there is this very basic primitive operating system, namely the BIOS. Then the BIOS will read CD ROM and we can install a new operating system to the hard disk. That's how a computer works. --- Now we have Android devices. - I think the SD card is analogous to a hard disk. Or am I wrong here? Then I read [Android Partitions Explained: boot, system, recovery, data, cache & misc](https://www.addictivetips.com/mobile/android-partitions-explained-boot-system-recovery-data-cache-misc/) and I got even more confused. - So, are all the apps in the data partition? Is the SD card the whole SD card? Shouldn't data be in the SD card? - Also, how can Android be bricked? - What is the BIOS of Android? - So, Android has a recovery partition, boot partition, etc. Are all those on the SD card? - Say, I really messed up with my Android and want to start from scratch. Say, I want to format the whole SD card like I want to format the whole hard disk. Can I do that? What are the consequences? - Is /boot like BIOS? Is it on an SD card too (the internal one?) - Is internal storage the SD card? On PC, we have memory and hard disk. It seems that in Android we have memory, and then the "hard disk" equivalent, called SD Card is also called memory again. PC|Memory|Hard Disk Android Devices|RAM|Memory - Do I get the analogy correct?

I've got this non-rooted BLU Energy Diamond with an absurdly long lasting battery that I use at work for testing apps on old devices, however, it only has 4GB of internal memory and a 16GB SD card. As we all know, **Google** absolutely forbids moving its apps and services to the SD card, while endlessly increasing their sizes for no reason, in an effort to render all phones obsolete as fast as possible. **The minute I enable Play Store + Play Services, internal memory is maxed out, without a single third-party app installed nor updated.** Manufacturers only allow bloatware uninstallation after facing lawsuits like this in China. I managed to remove bloatware without a lawsuit by using the adb shell , however, this is not nearly enough. Is there any hope of effectively **moving Chrome, Webview, Play Store, Play Services and all to SD card**? I don't care if there's a risk of rendering them useless, because as is, the phone is already useless if nothing can be installed when Play Services is enabled. I understand there was a **hack to use SD card as internal memory** on phones without that option, but I'm not sure if this was ever available to Android 5 or if requires a rooted device.

I recently formatted the SD card as internal on my Android 7.1.2 (LineageOS 14.1). Now the camera app is showing an error message that it can't access the SD card anymore. The error message is: "Couldn't access SD card". I can't find the setting to change the storage folder of the camera app. Does anybody have an idea how to fix that?

I've installed a micro SD card on my phone, as an extension of the internal storage, but it's not detected anymore on my phone... With some tools on the computer I found out that the micro SD card is divided into 2 partitions, android meta and android expand. I guess it's partitions for android extension storage. How can I make it work again? Is there something to fix this? I need to recover files on it, and it is super boring to use weird software...

I have a micro SD card adopted by an Android phone as internal storage extension. While being adopted it was partitioned/formatted by the phone with two ext4 partitions: android_meta and android_expand, which is easily decryptable in a Linux laptop using the key under /data/misc/vold. I'd like to free up some space on the card for an "external" aka "portable" partition for music storage etc, ideally using that Linux laptop: the idea is to shrink android_expand somehow. How do I do that? E.g. GParted won't let me do it - if that's just 'cos it's encrypted can I perhaps decrypt it, write it back onto the card, move/resize it as necessary using GParted or the like and then encrypt and write it back again? Thanks in advance!

I have a micro SD card adopted by an Android 8 Oreo phone as internal storage extension, so it has two encrypted ext4 partitions: android_meta and android_expand. I've cloned those partitions into the "far end" of a bigger card using Macrium Reflect 8 (selecting the byte by byte copy mode w/o any analysis and optimization if I got it right) and created "external" aka "portable" partition in its free space later so that it goes first (just to please Windows). I also cloned the GUID. Unfortunately my phone is reporting "Adopted missing" upon booting up with it. What else am I missing? Many thanks in advance!

I am trying to increase the internal storage of my realme narzo 30a phone. but it doesnt support format as internal. so i enabled usb debugging and used

set-force-adoptabe true

via

. Then i formatted it as internal storage from google files app. as soon as i press done, i get a popup saying sd card is ejected. I also tried mounting via adb using

mount private DISK;VOLUME

but i got an error saying its inaccessible... If I dont press done after formatting using files, it doesnt seem to get ejected, but it is not shown in storge... is there no way to use sd card as internal storage? what is funny to me is that it works just fine on a moto e40 i tried it in... even the speeds were not bad.

I asked another question about problems with the default launcher and one user suggested that I might need to check that my app is installed on the internal storage or the internal SD card, but I can't find anywhere in the app settings that shows that. How can I check where the app is installed?

I was using my Chrome on Android 4.1.2 on Samsung Galaxy S II and phone suddenly crashed. When phone restarted it looked like all apps are gone, even Google Play. App Drawer shows only standard apps like Camera, FM radio, Internet, Messaging, Phone, Samsung Apps etc. but all other cannot be seen there. Application Manager lists my apps under DOWNLOADED label, but instead of apps names (e.g. Chrome or Viber) it shows app IDs (com.android.chrome or com.viber.voip) and instead of app icons it shows some gray icon with labels Android and SD. Under ON SD CARD label it there are no apps. I don’t have external SD card. I used Android System Recovery to wipe cache partition and it wiped cache for all except Chrome cache. What can be problem? How can I get my apps back?

I just rooted my Moto G 2014 XT1064 running 5.0.1. I used this article to do the root process: http://maktechblog.com/how-to-unlock-the-bootloader-and-root-the-motorola-moto-g-2nd-gen/#Root Which evolved unlocking the bootloader (which caused data to be erased, of course), installing TWRP, then copying SuperSU.zip over adb, then going back to TWRP recovery and installing SuperSU through TWRP. Since then, /sdcard seems to be acting like its mounted as read only. I cannot seem to get anything written to it. I've tried to adb push files to /sdcard, but I keep getting the same "Permission denied" error. Taking screenshots don't work either, I get a "Couldn't capture screenshot" error. And I've also noticed the Twitter app is unable to display profile pictures nor pictures inside of tweets. I've tried numerous things, but I'm stumped. I've tried to see if its mounted as read only. Via adb shell, and su to get root, and mount to view the mounted file systems. Everything dealing with /sdcard, /storage/emulated/legacy, and /data/media are all mounted as rw (Read & Write, of course). Remounting them doesn't produce any errors, but has no effect. The file system for /sdcard seems to be just fine, as I can adb shell in, and use ls /sdcard/, from either regular shell or root. And via TWRP, it was able to successfully save a recovery.log to the /sdcard/ file system, indicating nothing should be preventing things from being written to the file system. I am also unable to copy files to it via Windows, it tells me "Cannot copy [file name] ... The device has either stopped responding or has been disconnected", and OS X still doesn't seem to recognize it at all despite installing drivers from Motorola, which has happened before I rooted it. What I found particularly weird is that I can download and install apps still. I installed a root checker app just after rooting it, and it worked, and I wanted to screenshot it, and then I noticed the issues happening. And I've even tried a free app from Google Play which uses SuperUser permissions and attempts to fix the sdcard file system and make it mount right. Still, I am unable to write anything to it. I've also tried to see if restarting adbd as root via the 'adb root' command would work, only to be disappointed because it doesn't work on production phones, despite my phone already being rooted. I'm pretty new to android in general, including rooting, but I've definitely gotten a good feel for how it works, when I installed 5.0.1 onto it a few days ago (It came with 4.4.4 and didn't have an OTA update yet). But now I'm really confused about why this happened after I rooted, and after a bunch of googling to find nothing helpful, I have to ask here. Any suggestions? Edit: Just to be clear, Settings also reports I have 2.4 GB available space, and the file I am trying to copy over is far less than that.

Nokia 6.1+ device using pixel experience ROM based on Android 12. - Adopted SD card as internal storage and removed it without '**Eject**'. - Afterwards couldn't read the data even on the device itself. - Copied the encrypted data ( mainly images and videos) to my PC. - Tried to make the data readable again, copied and pasted the data to another 2nd SD card by adopting it as internal storage, didn't work. - Adopted it as Portable storage as well. Could not read the data any way. - I Adopted 2nd sd card as Portable and internal storage multiple times but neither formatted nor "Forget" the 1st SD card 1 - Does the device store separate Keys for different sd cards when they're adopted as internal storage? 2. Can the **Original 1st key** still be inside the device system files as I didn't format or changed any system files? 3. If just one latest key is present inside the device, could this key decrypt my data which was 1st encrypted?? 4. Could this last key be used to deduce the 1st key ? I have Root access on my device and Encrypted data on my PC. Using CX file manager can access data/misc/vold folder which contains the decryption key But those KEYS inside are not being read by my android device. 5. How to access and Read the decryption Key(s)? 6. Then Can I copy and paste the Vold folder and save the keys on PC? 7. How to read and then use the decryption key to decrypt the encrypted data stored on my PC? Thanks
