I've been spending a lot of sleepless nights trying to fix this. I know there are a lot of threads like this on the internet, but I want to go a bit deeper. I have an HTC Wildfire S with only 512 MB internal flash memory. This internal memory has a partition layout allocation around 130 MB for the /data partition and around 290 MB for the /system partition. Both of them are full. (In addition I got a 16 GB SD-card.) Installing apps, upgrading apps, running most of the apps - impossible. Now, I knew it's possible to move apps to SD-card, the so called **apps2sd** procedure which offers very limited functionality to move *some* of the application data to the SD-card. Anyways after moving every possible data to SD the internal memory was still full and the phone unusable. I was reading about more sustainable methods like **data2sd**. I gave it a try. I used the instructions from htcdev.com to unlock the bootloader , I installed the latest ClockWorkMod Recovery and rooted the device permanently. Finally, I used the rooted device to install Android 4.1.2 AOKP Jelly Bean Custom ROM and Data2SD like discribed in the linked articles. But I was stuck the device was not booting until I removed Data2SD. The AOKP-ROM was working pretty well and stable, but installing Data2SD simply did not work in combination with Jelly Bean (SD-card formatting: 11 GB FAT23, 4GB ext4 and 256 MB Swap). Now, I tried to go for the **link2sd** approach. I reformatted my SD-card (14 GB FAT32 and 2GB ext4) and installed Link2SD on my phone as described here . I was able to move additional data and apps to my SD-card and could link some apps to the card. And now after some days playing around with all that usefull tipps from the internet, for example this thread: https://android.stackexchange.com/q/2065/29916 - **I am at the point where I started**. This is my result: Internal memory is still full and the phone is still unusable. (I would love to post a screenshot, but taking screenshots simply does not work currently.) How to finally fix my internal memory on the Wildfire S? Why is Data2SD not working with the Jelly Bean ROM and why is Link2SD so ineffective? Is there anything I'm doing wrong? The main problem seems to be the Dalvik Cache on the /data partition (around 100 MB). Is there any way to completly use the SD card to somehow get partitions mounted at /data and /system?

I only use Link2SD to link my game files to external storage, a straightforward and short process, then I'm able to play these games with their data sitting on my SD card Everything went to shit after I flashed my phone and upgraded to Android 12, Link2SD links my game data to my SD card, the only problem is when I launch the games, the games don't recognize the link and they create a new data folder in /mnt/runtime/write/emulated/0/Android/data. I downgraded to Android 11 but a slightly newer ROM than what I started with, same issues and it's very frustrating, I only have 64gb internal storage and I've managed to play Genshin Impact and Honkai Star rail until this whole fiasco. I've tried in-built adoptable storage, and adoptable storage with apps2sd, but nothing. Now I'm looking at downgrading to Android 10 and trying Fbind but I've been reading some stuff online and I'm wondering if this all stems from my SD card not using a Linux Filesystem, Please correct me because I really don't know what I'm doing Any tips will be appreciated, thanks.

I use Link2SD Plus mostly to link app data from my internal storage to my external memory, I don't do anything fancy like creating a second partition to link obb, I simply link the game DATA FOLDER (where applicable) to my SD card on the first partition. Now here's the issue, I recently flashed my device clean and upgraded from Android 11 to 12, I usually play my big games with the game files linked to my sd, I downloaded and installed the game files on my internal storage, I linked the data folder to my SD card, I launch the game and everything should be up and running but instead, it starts downloading the game's data all over again. Normally, this never happens unless I forget to bind the data folders stored on my SD card. I tried linking the base game and then installing the data, but that didn't work, I'm at a loss for what to do. I tried downgrading to Android 11 but Link2sd just isn't working the way it used to. Is there another/better way to achieve the same goal? I'm looking at Fbind but I have no idea how to use it, I'd appreciate a simple cmd line I can run Redmi Note 9 Pro (joyeuse) rooted with magisk

I have a Samsung Galaxy J7 Pro SM-J730GM purchased at a Sanborns shop in Mexico, running Telcel's stock ROM, rooted, with TWRP recovery and Link2SD. A couple weeks ago I repartitioned my SD card in order to use Link2SD's app linking function. I remember having to reboot my phone a couple times before it picked up the card, but at the moment I thought it had finally worked. However, apparently it was just a fluke, because today I restarted my phone in order to flash TWRP, and when I started my phone back it didn't detect the card anymore. The card is fine, as it can be read with no problems on a PC running Linux. The card reader is fine too, as the card is legible from TWRP and can be formatted without a hitch from Android. With that in mind, I tried formatting the card using my device's Set Up function, then I repartitioned it with my computer. When I inserted the repartitioned card, that's where my phone began refusing to mount it. Has anyone had any luck mounting a partitioned SD card on this model? Am I going to have to flash an aftermarket ROM into my phone? (PS: I'm going to try to reproduce it with a different card)

**Question:- Storage manager (SM) Partitioned Micro sd card but how to mount the extended partition and use it as internal storage.?** I purchased 6 months before, Samsung Galaxy s20 Fe with android 12 with 128 GB internal memory and a 128 GB external Micro SD card.

I purchased 6 months before, Samsung Galaxy s20 Fe with android 12 with 128 GB internal memory and a 256 GB external Micro SD card. I am an IT freelancer professional, so I have a job is for testing 1000's of different apps, and my main work is to install some video photo editing and some technical official apps to do my job in an instant go while traveling. In Android 12.0 of Samsung Galaxy S20 Fe There is an option of CHANGE option in Settings > App> Storage to change (move) location of app from internal to SD card in Android. But its the same like as in Android 5.0, it only moves the main APK files, leaving data, cache, lib, and dex in internal memory thus occupying space in internal memory. I want to keep my internal memory free for output files of video editing to fast rendering of photo editing or video editing file on mobile. MY QUERIES:- 1. Is there any option without rooting to move the complete apps (lib, dex, data, and cache) to an external micro SD card? 2. There was an option in Android 6.0 Marshmallow for adaptable storage to format an external SD card as internal memory and move complete application files. Can I do that in Android 12.0? 3. there any developer option in Android 12.0 to force or make default installation of apps in the external memory card so that all apps are installed automatically with apk,lib, dex,data file in the external memory card but it works with only 5 to 10 apps out of 100 it still leave some part in internal memory? 4. In Android 6.0, I tried to edit the app manifest through the APK editor to change the default install location of an app to external memory. Will it work in Android 12.0? But it's time-consuming to edit every application. 5. Can we root Samsung Galaxy S20 FE and use the Link2SD app or any script in boot.int or any other new application in Android 12.0 which with its script links all lib, dex files in a micro SD card? 6. Is there any other way or method or settings options in developer options or any other 3rd part application in Android 12.0 Samsung Galaxy S20 FE so that I can move (dex lib apk data) or install complete application directly to external micro SD card and keep my internal memory free for working or output files rendering ? The reason why I still want to move apps to sd Card while having internal memory of 128GB is for testing 1000's apps and editing and rendering short video and photo editing . I know External micro sd card is slower than internal memory but the app I install for TESTING on external memory will be rarely used may 2 or 3 times a year but for testing and reporting to companies i need to keep it installed in mobile for year to give usage or some log reports and its useless to give them space in internal memory and make them full my internal memory i cant uninstall or re-install them .

**Question : How to create Mount script or Link2sd symbolic link in adoptable storage (format microsdcard as internal memory) any help** I have an old mobile with upgrade of Android 6.0.1 marshemellow with 16gb internal memory(11gb reserved for system and only 5 GB free space for user apps and files). I want to make 128gb or 64 GB microsdcard as internal memory. I had changed many apps manifest through apkeditor and changed their default install location. To external still some files are moved and many apps cAnt change the manifest. So to add at least 60gb I decided to move apps and folder redirect dcim download whatsapp Facebook to external micro SD card so that at least 2gb space is always free in internal memory. Now the question and problem is that can I cheat or mislead the Android 6.0.1 marshmallow (without root or with root) through 1. using apps like link2sd or app2sd or folder redirection appps or 2. through SM PM command > adb shell sm list-disks adoptable sm partition disk:179:160 mixed 25 > adb shell sm format private:179,3 3. through creating own symbolic link boot.init script to decieve Android 6.0.1 is and move or link apk files like data lib hex off apk to.memory card 4. Can both adoptable storage (format as sd as internal and the link2sd symbolic link mount scripts) work together as after formatting as card as internal Android assumes no external card and the how will be it work from redirecting or symbolic link to internal folder. I tried Inc it gave "Mount script error" Any way or script if I can write or tell it will be great help for my problem.

I have plenty of space everywhere else. How can I fix this?

I haven't used Link2SD yet to move apps, because there is one thing I'm confused about. Currently, I have a 2 GB SD card on my phone, but I'm thinking to buy another 8 GB card later. What will I have to do if I want to transfer all the apps (linked/moved using Link2SD) to my new 8 GB SD card?

When I open Link2SD, it asks to recreate mount scripts: I use ext4. After a reboot, when I open the linked application, it gets stuck and black screen till reboot. I use ext4 as the 2nd partition, but it shows ext2 in Link2SD, and all my applications are now stuck. mount: mounting /dev/block/vold/179:98 on /data/sdext2 failed: Device or resource busy How to fix this?

I was using Link2SD and linked some of my apps to an SD card including internal data. Recently, the second partition somehow got corrupted. I deleted the partition and reformated it. Now I can't install any of the apps previously linked. It shows insufficient space error, but there is plenty of space in internal memory, SD card, as well as SD card's 2nd partition, and I can install any other apps. I tried the clean-up option in Link2SD. It cleaned up the Dalvik cache of old linked apps, but it didn't work. What to do now?

I have Sony Xperia M2 (D2303), and i have had Link2sd for quite some time. A while back I created a partition in Minitool and mounted it as ext4 in Link2sd. Sometimes it crashed, but usually waiting or restarting would help, because all it needed was to link lib, obb and dex files. However couple days ago i set up Sleep as Android, and before i woke up a family member took the phone for a while (Facebook, Candycrush - which heat up the phone a lot). So when i woke up and tried to shut down the alarm i couldn't, Sleep app kept crashing. After that I rebooted the phone, only to find out i have 10 installed apps showing, apps showing crash messages, even if i didn't have them in the background. On top of all there is an alarm icon below the clock which i can't turn off because Sleep app is not showing in app drawer. After 2 days I figured i might flash SuperSu again from twrp, because it wouldn't update binaries. Tried turning Link2sd into a system app to mount ext4, it only shows some grey screen for a second, nothing changes. In settings there is Sdcard present with similar space i had before(1 GB more space- probably just app data wiped) In Link2sd there is Sdcard, as well as the second partition which is showing as unmounted In DiskInfo app i see partition by its name and allocated size(mmcblk1p2) I see Sdcard in computer when plugging in usb. However, I don't see it in Minitool, Disk Management or when running cmd - "diskpart" - "list disk" commands SDHC card is Kingston 32 GB class 10. Total commander app allows exploring Sdcard which is not appearing in Minitool. Not only is partition missing but Sd card as well. Thank you.

I've been poking around using GParted on my 128GB microSD card so it can use two partitions for link2sd. Problem is, no matter what I do, each time I place the card in my phone, it says that the card is corrupted. I had been using the card just as storage (it was formatted by Android itself). Technical details: Phone: Samsung Galaxy Express 3 (SM-J120A)(sometimes called Samsung Galaxy J1) Version: 6.0 Marshmellow SD Card: Samsung EVO Select 128GB Root status: Rooted When I look at the partition after the phone formats it, it is an exFat partition with the Flags "boot" and "lba". Reformatting it myself to exFat with no Flags causes it to give an error in the phone "This card won't work". If I try to give it flags, only the "boot" flag is applied. Anytime I press the "lba" flag option, it won't even check the box (its not greyed out). Other flags work fine. Even if I use the command-line (Parted) it still won't apply the lba flag. To confirm that the card isn't broken, I have stuck it back into the phone for it to format. Works perfectly. I've even formatted the entire card to Fat32. Stuck it in the phone, no problems. Fat32 and ext4 partition combo does work. Other than that, it simply will not accept a exFat/ext4 combo. Or even exFat alone. What I really want is to have 32 GB as an ext4 partition, and the rest being exFat. I don't want to be limited by Fat32's 4GB file size. Though aside from video, I'm not sure what large files I might have (emergency storage?). Recommendations, advice, and solution(s) would be most appreciated.

Well, this question is targeted for those few devices without support for an external SD card as well as merged storage, for example my Micromax Canvas Knight A350. I thought this up today: If we take a QEMU disk image file (.img), set it to static with a size for, say, 4GB and format it to ext2 and copy it over to the Android device's internal SD card, can we mount it as /mnt/sdcard2 or something similar as a loop device (it appears that loop device mounting is possible on stock Android 4.0.4 and up, at least for some Samsung devices)? Secondly, will this work with Link2SD? Context: My device, as mentioned above, has a 2GB /data partition which is fast running out. I thought this up as a last-ditch effort to extend its lifespan (because it has 25GB /sdcard0 partition`, and I don't use more than 12GB of it), and would like to get the theory of this validated or refuted before I go about trying this on my device. **NOTE:** Any alternative suggestions, such as FolderMount (kindly suggested by @Izzy in chat ), are also welcome if these are accompanied with **proper usage instructions** for this specific case, that is, link folders from /data to internal SD. Side Note: Not currently considering FolderMount as it's advertised for internal SD to external SD linking, not /data to internal SD linking.

I am using an Xperia X10 mini pro (Android 2.1-update1). I rooted the phone and partitioned the 8GB SD Card into two parts. 1. ext3 2. FAT32. I installed Link2SD to move the apps to SD Card. This has been very useful as this application has an option to move the installed/updated apps to SD Card automatically. But recently it happened to remove my SD Card from phone and inserted another 2GB SD Card for some other purpose. I started the phone and the apps that are showing on phone aren't working as I installed them on my SD card. So I put my 8 GB Micro SD card back to phone. Now the problem arose. I was not able to access the apps installed on SD Card. I had to reinstall all the apps that are there in my phone. Is it how it behaves ? Don't I remove my SD card from phone ? I did a little amount of Experimenting on this and found that its happening only on inserting another SD Card. My mobile is searching for the apps on the newly inserted SD Card. As there are no apps found it might be deleting the links on phone memory. This is my guess only. Still the question stays "How to overcome this kind of scenario ?"

I've a Lenovo A 7000 (64-bit) Android mobile. While using [Link2SD](https://play.google.com/store/apps/details?id=com.buak.Link2SD&hl=en) app on my rooted mobile, I observed an error after trying to move an app to SD. It says: > WARNING: linker: could not load library "libsigchain.so" from LD_PRELOAD for "/system/bin/sh"; caused by "libsigchain.so" is 32-bit instead of 64-bit CANNOT LINK EXECUTABLE:.... What does this error mean?
