[Q] HTC One M8 SD card

Hi All,
I went and looked at the HTC One M8 today and was very very impressed. Looking to uograde from an s4 to the M8.
The salesmen said something interesting though and after a little research I am concerned.
He said that 3rd party apps will not be able to access the sd card at all. I know there have been conplaints about this in regards to KitKat.
As I live in Australia all the plans have horribly low data so cloud really isnt an option here, especially to store music and video.
I was just wondering if this were true? Are they able to be installed on the sd? are they able to write to sd?
Thanks for any advice

Just tried and yes you can but I am rooted don't know if that's why it moved

I'm not rooted. Using solid file explorer, I'm not able to write to the card. Very frustrating.

It's a new security feature of Kit Kat, stops apps from having full read/write access to the whole sd card. The developers just need to update there apps to resolve the issue. I had the same problem moving files across but came across the answer in another thread on here.

What about the camera? Can you change the default storage for that?

Is there anyway to restore write on SD Card capabilities? Did anyone proove it?

I have just got a HTC one m8 it's not rooted(yet) I can save photos to the sd card but cant copy from internal to it. I can't even create a folder in the ext sd card where is the stock file manager I can only see Polaris if that's what it's called If I try to copy a file in that app it will not even show the ext sd card. Help any one

root it..

This is a feature of google kitkat 4.4.2. Anyway is supposed to work with default file manager. If not, you need to root and instal Sdfix from play store.

Root and install SDFix from playstore or root it and flash a custom ROM. AFAIK all the custom roms have that fixed by default now without having to install an app.

I tried the SDFix on stock rooted rom, but titanium backup still cant write on SD card. (It says: this folder is not writable) i even tried modifying system/etc/permissions/platform.xml manually but still no luck.
Is it an issue with titanium backup, or am i doing something wrong?

You need to flash a custom kernel with system write protection turned off then you can use something like SDfix or foldermount to enable writing to the external SD for all apps
Try Elemental kernel, it worked for me.

Stock and rooted here and sdfix worked fine. Titanium and all other apps write to SD fine.

No, not true! I am on stock rom / kernel, just rooted and SDFix installed, and Titanium and all other apps read /write on extSD. No custom kernel requied!

Didn't work for me, were you s-off?

Tried using the SDFix. Checked the permission.xml file. The changes has been made. However, once restarted the phone, changes have been revoked.
Using stock rom/kernel, rooted. Still no luck...seriously wtf.

Workaround for storing/modifying files on SD card
Hey guys,
I'm myself in shock what Google did in KitKat - that's just pure stupidity.
However, I'd like to share with you a simple hint on how to actually make use of SD card, using tTorrent as an example.
As you know, it is no longer possible to select a directory on SD card to store downloaded data - apps no longer have permissions, including file browser in Polaris Office. Well... it is not entirely true.
Let's say you want to select a directory on SD card, so tTorrent has as much space as big your SD card is.
All you have to do is to select a directory which your app has an access to.
What's the directory? It's the directory of particular app:
/storage/ext_sd/Android/>>your app's directory<<
In particular case of tTorrent that would be:
/storage/ext_sd/Android/hu.tagsoft.ttorrent.lite/
That's all. If you select above path in tTorrent, tTorrent will have a full access within it, so it can create/modify/delete files in this directory.
The same rule applies to any other apps - all you have to do is to select your app's directory/put files in it and your app will be able to fiddle with these files, inside its directory on SD card.
I know it is not as elegant solution as rooting device and modifying /system/etc/permissions/platform.xml file, but at least it's something.
Have fun, folks, and let's wait for an update from crazy Google - I heard that they are receiving tons of complaints about this "security feature" which I personally call simply a bug.

So that's the problem with KitKat?? For example I couldn't unpack zip on sd card, I had to unpack it to the internal memory. Since m8 hasn't default explorer, is there any explorer that doesn't have this issue, or I strictly have to root it??

[Q] Cannot write to extSD card using any third party app. Any workaround?

Write to disk denied whenever using any third party app.

welcome to kitkat. if you are not root. nothing we can do to help you out.

Thnx a lot for your reply . Best rooting method for the Tab S 8.4 SM-T705?

currently there's only one method. cf-autoroot which... will make your knox counter 0x1 which mean your warranty is void in some country.

Did you guys get the microsd writing working with root+sdfix app? It doesn't work for me even though sdfix runs and says fix done. I also tried manually editing the settings file and I am on rom supersamsung v2 which is supposed to be fixed on rom level but nothing works! Which file manager are you using?
And the usb file transfer in either camera or media device doesn't work. I don't know if it is related. I have 128Gb card... I'm ordering original Sammy microsd now if it helps.

What does it says when they don't let u write to SD card?
I did the root and supposing using a rom that have the fix installed but I still can't download torrent files to my card, not sure faulty card or just fix not working.

Well basicall if I try to make a new folder or copy a file to extsd root it gives an error msg or restricted access or what ever depending on app. I have used es file manager and other file managers.

Same issue with my 8.4" wifi. Tweaking apps say that writing is enabled, but still not working. :crying:

same here. Spent hours to look for alternative solution but non avail. Sigh... those fixes app and platform.xml editing all done but still not working.
bought a Samsung EVO 64gb, but technically its useless now. Back to 16gb internal storage....WTFFFF

i have the same problem with scan disk SD card i tried Kingston and working fine

You can thank Google/Android for deciding user needs are irrelevant. The only way you are going to write to the external SD card on an unrooted stock ROM is use Samsung-provided tools like their lousy file manager and gallery. Third party apps are useless unless you are willing to root and ruin your warranty.

Is your tablet rooted? you may need the sdcard fix due to 4.4 sdcard write to sdcard issue. Try to configure firefox to use internal storage if you're not rooted.

Tell us more about your device, is it root? stock firmware? custom recovery?

I'm with Buhohitr, except that I KNOW that your (OP) problem is Kitkat's write protection. I had this exact same problem after first installing KK. To fix it, use SDFix ( https://play.google.com/store/apps/details?id=nextapp.sdfix), but you have to be rooted.

I am experiencing the same issue with firefox but also with other browsers like dolphin (with different error message) . but not only with browsers but also with es explorer . i applied all the fixes sd fix etc while rooted , i also tried unrooted . my internal sd is only affected by this not the external. I cant change anything in internal sd it is like locked. This is happening only in the official kitkat rom and the problem appeared all of a sudden.

Try this fixer:
https://play.google.com/store/apps/details?id=jrummy.sdfix
I had to use two different apps, one for my LG phone, and the other for my tablet. One app kind of worked on my tablet, but not 100%. I cant remember which app I used on which device though.

Thanks for your suggestion. I finally fixed the issue first by installing supersu( already have towelroot) . After that i installed the following fixers : sd fix, sd fix tool and int sdcard write fix. The problem is solved with all browsers and es explorer. Maybe towelroot alone without supersu didnt left the fixers work before. I am not sure.

Same here
I also have the same Problem on my rooted Samsung XCover2. BUT this has Android 4.1.2 and most of the apps wich helped you didn't work on my older android version. What can I do??? Could I do anything with ADB, like force installing these apps, or do I have to reset it on the stock rom? What als a problem could be is, that I installed the false baseband version, but everything works except this :/
Please help me

Those apps change the permissions for apps to be able to write to the SD card. There is also a tweak you can do to a system file to allow apps to write to the SD card.

Dang, My fault for not following the discussion. I got excited about this app until I realized under "Read More" that it requires root.
Edit: Actually I correct the above, upon opening the apps page in PlayStore, it clearly states ROOT requirement both up top and right above "Read me". blah
Just posting to inform anyone else that gets confused as easily as I do. :crying:

Permissions to external sd card

Just got the h815 (cze with rom v10aEURxx) .
It seems that some apps cannot write to external sd (e.g. Solid Explorer) .
Since I am not rooted yet (did not even attempt to unlock bootloader) I cannot use apps to correct external sd permissions (such as SDfix which requires root) .
Meanwhile I manage external sd writes with MyFiles and with ES Explorer.
Can someone suggest how to enable Solid Explorer SD card access without root?
I still wait for an xda developed root method which is reversible.
Thanks

You can't, but root explorer will let you manage files on external card though.

Fair point. G.Photos is certainly reading the external SD perfectly well but it can't delete things there. You need to use Gallery of a a suitable file explorer for that.
The stock camera does store photos to the SD now. It's just offered me that option.
For me the important thing was that my FX Explorer and TI Backup etc be able to write to the ExtSD and they now do.
Cheers

That fix will not work for him as he is NOT rooted mate.
And that fix came from one I did and submitted to cyanogen more then 2 years ago when we first got KitKat. Lol

A good idea for Photos is Xposed + XInternalSD.
I have a question. Does Cyanogen use the same motif as stock roms for r/w permissions ? What is the primary SDcard on CM, internal or external?
