Can't write to SD Card (EMUI 10) - Huawei Mate 20 Pro Questions & Answers

I can copy/move files from internal storage to SD Card if I use the built-in file manager. However, if I use any 3rd party file manager, the operation will fail. It is as though the SD Card is read-only. I can copy from the SD Card to internal storage just fine.
I've tried ES File Explorer, File Manager Pro, Solid Explorer and they all failed. I've given grants to write to the root of SD-Card. Does anyone have any idea how to fix this?

Try with a real file manager like

Mixplorer works great. Root Explorer also works.
Thank you for your recommendation!

I really don't get it. At first, nothing works. Then when I install Root Explorer and grant storage access to the root of the SD-card, it immediately works.
Then I tried MiXplorer and it also works. Now when I return to Solid Explorer and it is working now.
What's going on? Does Root Explorer unlock something which makes it "click"? I don't get it at all. I only hope it is reliable in the long run and not switching "on" and "off" randomly.

Root Explorer has been the ultimate for me. I bought the paid version when it first came out years ago. It always acomplishes whatever task I need it to do.

Not Working
Not working for me.. I am using Honor V10... recently, I installed the android 10 (EMUI 10) update via ota (over the air). I have tried Root Explorer, ES file manager pro, but no file manager is able to write to external card except default file manager (which is pre installed)
PS: My phone is not rooted.

Any other workaround?

I still have the same problem...
I have a new P30 Pro and Nano SD card Just arrived.
I can write (and read) the card by external reader, connecting the phone via USB to a PC, etc. etc.
But when the card is on the phone I can only use Heawei file manager!!!
I have enable the option allow apps to write to external card.
I've just update on EMUI 10 build 10.0.0186
I can't beleive I tried a lot file manager and also some alternative app like quickpic and no one works good!!!!

Fix the problem...
After enable the option allow apps to write to external card, I tried to disable developer settings.
Also tried to active some app I've disable before... 2 app, default browser and HiCare!
That's all and now I have no problem writing Nano SD card with all of my app!!!

Issue resolved by installing FX file commander

Hi there.
I have the exact same problem.
None of those steps helped me
I tried installing every single Root Explorer there is in the Play Store, but none worked.

I enabled the default browser and the HiCare app (actually they were not disabled, so I just opened them to complete their setup) but this did not help either.
I even formatted the memory card (using my phone "format card" option) and then reset my phone to factory defaults and set it up again from the beginning without restoring backups.
I still have not found a solution to thus issue, though.
Any ideas anyone?

I had to instal FX file commander to get SD card write permission....I can't make it stick, every time I reboot I have to reset the sd card write permission.

I have similar problems relating to this thread on my mate 20 pro after updating to Android 10 (EMUI 10). I've tried all the methods mentioned here and it worked briefly before restarting the phone. After restarting the phone, it went back to being unable to copy files to External Storage.
I noticed that i was able to delete and rename files on the external storage but i just can't seem to copy anything into it.
I can copy files from the external card to internal storage but not the other way around.
Tried using MiXplorer, the only way i can copy files into the external card is by this method:
i copied the file and it shows error, but there's an image of the file created on the external card with 0 kb. Then i overwrite the file and replacing the '0 kb' file and it worked. And another method to just to use the built-in file manager which is a pain to use and the UI are crappy.
It was a lengthy method and therefore I decided to downgrade to Android 9 for now.
I also noticed i can't change the download directory of my Ttorrent app to any folder of my choice in external storage.
anyone can suggest a better method to overwrite this external drive issue? Thanks in advanced.

This this the "official" reply at the Huawei forums:
https://consumer.huawei.com/en/comm...-disabled-for-3rd-party-apps-!/topicId_90489/
Now, what I've come to notice is the following:
- All Huawei and Google apps I have tried, do have access to the memory card (e.g. Google Maps is allowed to save its offline maps on the SD card, the same for Google News and the articles it downloads)
- Some 3rd party apps do have access. E.g. Here We Go maps can save its maps on the external card. ASR Voice Recorder can save its recordings to a specific memory card folder, the one that is automatically created -on the card- by the app when it is installed on the phone. Maybe there are other app that we will find they can, too.
- So it seems that the rule is not general, as Huawei implies at that thread I have posted above.
My biggest concern was that MixPlorer has now limited use, and this is kind of sad as it was my favorite explorer.
Huawei Files manager is not bad, it's actually quite OK, but it bothers me that you cannot add 3rd party clouds on it. If it had that option I would be happy with it. I like it that it has that "favorites" option. For now I have created a folder "My Archives" on the internal memory and I initially save almost everything there (e.g. my Nova Launcher backups). Then I use Huawei Files manager to move them to the external memory card on the folders I want.

Hey that's a good idea of creating a temp folder on your internal drive before using Huawei file manager to transfer everything out to your external card. However it requires additional steps to get it done but it's a good idea nonetheless. Thanks for that suggestion. For me i'm so used to be using solid explorer to do all my file operations as it has google drive integration which makes it easy n fast to transfer between drives. So i guess my best bet is to downgrade to android 9, it's just much more comfortable to work with and in my opinion, android 10 is not that big of a deal and not much substantial changes anyway. Hehe.

Every reboot I always have this facing problem!
Sometime I must reboot because my smartphone switch off for low battery....
When I reboot try to disable and re-enable the special option in developer menù, also try to uninstall and after install again the memory card (from setup/memory menù).
After that try to copy some file to memory card with default file manager an default Gallery...
Sometimes it is enough sometimes I have to try more and more... But after several time it works!

Xplore
Try xplore by lonely cat games. It's working on my mate 20 pro and survived reboots.

[Q] AOKP/CM9 doesn't "see" files in file manager.

I haven't taken notice to any others having this problem, but I may have simply missed it. When I use AOKP or CM9, I can't find certain files on either the built-in storage or in the sd card that I put in it today (I don't know if I have to do anything special to it or not -- do I have to format it?). I have some backups of apps and a few other things, but I can't browse the folders on my sd card because, for some reason, they're simply not listed. Regardless of file browser, I can't see certain files and folders.
Has anyone else had this problem and/or does anyone know what might be causing it? The files aren't hidden and I can see them just fine when I restore my rooted/stock 2.3.4 backup.
There are a couple possibilities why you can't see things. One is that your ext SD card may be now called EMMC. Two, and most likely, you have to give FE root priviledges in preferences.
Remember that any folder with a . (Period) in front of the folder name will be considered hidden. Some apps hide the folders they create automatically and as previously stated above if the file explorer yer using doesn't have root it may not be able to see them.

So how to show the hidden folders that have a period in front of them ? remove the period and the app will show itself ?
Am new to all this so please bare with me.
am trying to gain access to my phones root folders,Apps,Apks....and to make my phone read my external SD card.
my previous ROM was ICS 4.0.2. then i Rooted it..i used Method 2 + Method 2 Advanced---thanks to Jiangyi
Reference : http://forum.xda-developers.com/show....php?t=1679778
Then i flashed aokp_i9100g_jb_milestone-1 and then gapps-jb-20121011-signed for jellybean 4.1.x
The AOKP_Milestone works fine but my problem is that am not able to see my file manager on my device.i can see them on the computer only when i hook the device (i9100G) to the Computer and some of the folders do have periods in front of them,i did fix permissions from CWM recovery,but still nothing.
before flashing the Custom ROM i did not do any backup or restore, i had some applications on the device and some on the External SD card.
am aware of my mistake which probably was the sol issue of problem
when i try to go to Google play through the device it simply does not connect to it,"thats a problem that i had even on ICS"i was able to go to Google play from my computer and install an application from there ,but now when i try to install an app like the AppBack or any app for example
it says that the app has installed into my device but am not able to find it anywhere neither in the device or the root folders of the device through my (computer) only. because am not able to see any of my files through the device.
the Google_Library,music,files,diary,videos apps just doesn't exist. i see them all piled up in one widget in a faded color but they are simply not accessible.
and my mini external sd card can be seen by the device from the storage section in settings only but it says "Mount SD card
Insert an SD card for mounting"
when i click on it nothing happens.
i have not formatted my external SD card after flashing aokp rom. am not able to from the phone nor from the computer and i dont know what to press in CWM recovery in Advanced section so many options there don't know which one to do and which one to leave alone.
so what is my problem, what is the solution for this?
thank you

This forum is for the i777. You don't have this phone model. Please ask in your own forum. All u need to gain access to system files is a file manager that allows root access. For hidden files, I just use a file manager that has an option to show them.

[Q] Moving app Data to External SD card

Hi Guys,
I have karbonn A15 android ICS(4.0.4) smartphone, its not rooted.
I want to move the app Data to my external sd card, i tried to move the data folder from the internal SD (android/data) to External SD (root folder), just to check whether it releases any memory in the storage section in phone settings. but the internal storage was same, there was no change, can anyone tell me where does the app data resides in the internal memory, its fine if i can move app data manually to the external sd card.
I also want some clarification on below questions:
1. Also i want to know whether there is any risk rooting phone like (Bricking Phone), as i have bricked my previous Galaxy Ace when i rooted and used ROM manager.
2. Also i have heard about Folder Binding app which automatically transfers App Data to External Sd Card, is there any risk of bricking phone.
3. Whats the easiest method to root Karbonn A15 phone, i am not that tech savvy, so easiest method would be grateful in rooting device.
My concern is just to move App Data to External Sd Card, because i have some app whose Data increase very frequently (E.g: FireFox app).
Answers to this would be really appreciated.

Rooting:
here are the steps
the driver files are included on the phone internal card called pcdrivers.zip. you can connect the usb mount the internal usb storage and copy the file to your pc. if you face any problems you can download the file from here
1. Enable USB Debugging -> Under SETTINGS -> DEVELOPER OPTIONS
2. Install the drivers for the phone.
3. download "Android Root Unlock" from sourceforge.net and extract it to your Disktop
4. navigate to the above folder and run the batch file ICS_Root_Unlocker.bat
the batch file will reboot your phone a couple of times and will wait with a message "Press Any Key to continue"
IMPORTANT NOTE : if you PC is saying "PRESS ANY KEY" note if your phone is on or rebooting....
if it is Rebooting, wait for it to start before pressing a key
5. After a couple of boots the phone will be rooted
6. verify that the Root is complete by observing a "Superuser" shortcut in the application list
Moving Apps:
Once rooted, download Folder Mount From the Play Store
- Once installed, open FolderMount and grant superuser access when asked.
- In FolderMount, you have the options to:
- Name your folder (IE: "Generic Game 1")
- Select the "Source" Folder (the one on your local storage)
- Select the "Destination" Folder (the one on your SD Card)
When you enter these details, it will then move them to your SD Card!
I highly recomend FolderMount Pro, because it also shows you filesizes when browsing.
Common Locations of Large Files:
Two common locations for games (IE: Gameloft games, EA Games, etc.)
Android/data
Android/obb
I know it's not the easiest process ever, but hopefully I've explained it enough to get people started.

Is there any method/app that can provide a similar functionality without rooting the phone? I tried rooting my Karbonn A21 without success and do not really want to brick it?
Also is there any way of backing up the phone and app data before rooting? Will the existing apps and data be wiped out by rooting?
Thanks in advance.

foldermount
so quick question, i transferred games to external sd, worked fine and all, but after a while my games asked me to download the files again, anyone know a solution?
I m using foldermount but there is write error mention that was unable to write into the external sdcard caused by a permission issue where normal apps are not able to write anything into storage/ext_sd. What should I do next to solve this problem? Attempt to recover using the apps not solving it.
This is what i mean.
Moving app Data to External SD card
in particular the movement of android apps data from internal memory to SD card is a simple process, but the problem with these issues is your smartphone is to be a latest version like 4.3 version.
Idea
Can I move the game folders from Internal Storage: Android/data -> SD card: Android/data, will it work on non rooted phone? In the Data folder on the SD card are partition of some apps and they work just fine. Same with folder "obb".
moving apps data and obb to External sdcard.
I recommend using an app called folder mount. ..it needs root but it's as easy as fishing in a barrel. .. I am using It and it works fine... and now you have a clear space in your internal storage.
Hey, I followed above instructions and my phone Samsung S5 6.0.1 successfully rooted, but now I've entered into an endless restarting loop.
Please help what's the problem might be?

[Q] can't create new folder in external sdcard

Hi,
I bought a z2 yesterday. formatted my old 16gb microsdcard to use in my z2. I can see the folders and the phone can read my card. So i tried to download a file directly to my external card but it showed me a error lik "no valdi folder" or something like that. After i tried to create a new folder in my card using a file explorer but it gives me a error "operation stopped". Any idea why and any solution?

On Android KitKat applications aren't allowed to modify the files on the SDcard. They are only allowed to place files in their own folders on the SDcard (/SDCard/Android/data/app_name if I remember correctly).
You can fix this only by gaining root access and modifying build.prop.

So this means i cant save any file to my external sdcard?
rooting wouldnt be a problem.. but editing the build prompt..?

Uch, I was wrong about the build.pro. Actually you need to modify "/system/etc/permissions/platform.xml".
Here is some reference:
http://jrummy-apps.com/fix-sdcard-on-kitkat/
Root access is essential.
You can create a folder if you use the file explorer that came pre installed on the z2, all downloads go to internal storage but can be moved to sd card with 'file commander' this is the only app that can create and move folders to the sd card, apps such as astro and es explorer no longer have the permission.
Maybe I misunderstand the problem, but PocketCast can download and save the files to SD card without any problem. So, if this one can...
Yes PocketCast CAN write to the SD card, but only in its own folder, not everywhere. And it could write to a public folder (there are some defined in the Android SDK).
See Jackos post above...
Only software that is installed as system software may modify the files on the SDcard outside their personal folder. For example the build-in file manager.
File Commander (The built in file manager) is able to read and write to external SD. Use it instead of any other third party file manager app.

Write to external SD.

So, I'm not a noob, been rooting and running custom since the Nexus 1. I've searched and tried every fix, but no joy! I'm running doom's latest kernel and Monx latest rom. I've manual changed the proper files, and I've used apps like Fix SD and others and still can't write to my external SD card. Obviously, I'm rooted, so what am I doing wrong? I've seriously tried everything! Even the Music to SD module for exposed acts like it works, but when I try to use Play Music, it says "no space available". Even the Z2 built in "Transfer to SD" facility fails.
Please help!
Thanks,

Try this:
1. Using a root-enabled file manager like root explorer, navigate to /system/etc/permissions
2. Edit platform.xml file and find the WRITE_EXTERNAL_STORAGE permission.
3. Add this group definition: <group gid="media_rw" />
4. Save changes.
5. Restart.
:good:
if the above method doesent work for you
you can try using a xposed module called handle external storage, it automaticly alows use of your External SDcard by default
*(you need root , xposed installer and the modle its self (it can be found from within the xposed installer under downloads)
Tried both these methods. To be fair, I tried them both again, just to make sure. As far as I know, all methods modify platform.xml, but no matter what I do, I can't write to the sdcard1 folder. My usual test is using Root Explorer to try and create a folder on Sdcard1. Always fails. Honestly, the ROM I'm using should have been enough, as it comes with write to external SD already enabled via the platform.xml tweak already. I even did a full factory reset yesterday to test. Still no joy.
Any other thoughts?

Still not working
Many thanks to the gents who replied already. Unfortunately, none of the posted solutions are working. I can't find any information in the forums or elsewhere online that points to this. Everywhere I look, it says that the modification to platform.xml is THE answer. However, I've made those modifications nine ways to sunday and I still can't do anything with my external SD card. Can't create a file or folder using Root Explorer or E Strongs. Can't write backups using TiBu is the BU folder is on external SD, etc. Can't set then succesfulyl use the save location for camera or music apps as external SD. Very frustrating.
Has anyone seen or heard of this happening?
Thanks,
-Hans
possibly a bad card?

Nope. Card works fine as far as I can tell. I can write to it via MTP when connected to my lappie and I can read from it just fine. But, I'll try a spare card when I get home just to completely verify.
Thanks,
i'm having the same problem but my phone is not rooted, i usually us ES File Explorer to do my file browsing and management but for some reason i can't delete, create or rename files or folders on the external SD card.
i did a clean format with my SDXC card in the phone when i first started the device and that's usually exFat. and thats when i started to notice the problem,... i couldn't delete or create files or folders from the ES File Explorer app,.... so i did a clean install again with the ES File Explorer and the problem is still there,.... also when taking picture and deleting the unwanted pictures that i took.... i would still see the pictures i deleted in the picture gallery / album....
im still confused on whats going on,.... last night i reformatted my SDXC card to FAT32,... but the problem is still there,...
i tried using the File Commander app that came pre-installed with the device...... for some reason i can rename, delete and even create files and folders.... this is the only app that let's me do all those things when it comes to the external SD card.
other apps such as QuickPic won't allow me to delete, rename or whatever i have to do my pictures on the external SD card

If you're not rooted, it's how KitKat now handled external (SDCard) memory. It does not allow apps to read/write outside of it's own folder.
oh wow,..... so what about the pictures i took from the camera? i can never delete picture's??? (data storage: SD card)
i guess i have to get use to using the built-in apps to do some of the stuff i need to do,...

Yeah. That's expected behavior on a non-rooted KK phone. My problem is that I'm rooted and I can't get anything to write to external. Total Commander, Root Explorer, ES File Explorer, Camera apps, etc. Nothing will write to External SD no matter how many times I make the required mods to the platform.xml file. It is driving me nuts.

I had the same issue before when I upgraded my S4 to KK, but installing FolderMount solved it, when I started the app it showed me a message that my phone has some settings that will not make the app work and it asked me if I want to correct it.. I said yes, restart and viola every thing is okay...

I don't know if it will work on Z2 ( I still didn't have it yet ) but you might try it...

Yeah you need to use the built-in file manager, File Commander, to delete your photos on microsd for non-rooted.
Looks like it was a bad card after all. I swapped it out and now everything works as it is supposed to. I have other issue, but I'll open a new thread for those
Thanks for the help folks!

Why was I able to write to SD cards on 4.4.4?

So first off, I'm familiar with how KitKat doesn't allow 3rd party apps write access to SD cards.
However, I've been using Solid Explorer to manage files on my SD card for some time now... Long enough to move well over 20GB of music from a LAN share to the card. I'm not sure why this worked, but I didn't question it. This past week, without really doing anything to the phone, that ability went away. Solid Explorer now gives the standard spiel about KitKat and SD cards.
Am I overlooking something here? Why did this ever work, and can I get it to work again?
better .... try esexplorer
I've explicitly removed and avoid ES Explorer for getting progressively sketchier.
Solid explorer is perfect as it is.
First try this:
https://play.google.com/store/apps/details?id=nextapp.sdfix
If it works, then check the permission for Solid Explorer. Usually, the app ask you for permission, don't remember where or how, but you could try to uninstall the app and then reinstall it.
I installed Advanced Tools to fix the SD card write access. Go to Settings and Root, and then 'SD card write access' to fix the permissions. I'm on 5.02 rooted.
