Playing .mkv (samsung tabpro 10.1)

Hi all,
When i put mkv files on external micro sdcard by a usb to microsd adapter.
The mkv files dont play on mxplayer on my samsung tabpro.
But when i use kies software from samsung and put the files by connecting the samsung tabpro directly to my pc.
The files come under DCIM/Camera/mkvfiles on the microsdcard the they play with mxplayer.
Just to let people know here.
Seems very strange huh.
I wanted to buy and still going to if all works on mxplayer.
But i search really hard why my mkv files did not play on my samsung tabpro.
Any reason why i need to use samsung software to put files on the microsdcard to play mkvfiles.
greetings

Hi,
This is very strange because storage location does not affect playback at all.
If you unplug USB connection immediately after copying file, file can be corrupted because file may still being copied by Windows USB driver or Windows file system. Use "Remove device safely" menu on the Windows notification bar area. It will ensure file buffer being flushed.

It's due to the android restriction introduced on Kitkat onwards. It prevents the third party applications from directly writing on external sdcard. They can ony write in their respective data folder in sdcard. If you have rooted device then you can fix it by downloading a simple application. Else you have to use Samsung file manager.

As @bleu8888 said don't unpulg the usb device during copy.
Sometimes background process may still copy. Before unplug the usb test the copied file is whether playable or not. If you are still unable to play check the hash values of both files (like md5 or sha1) to ensure the file integrity. Most of the latest file managers like es, Fx can do this. If it doesn't match there should be some problem on your samsung file manager.

Hi,
I think its indeed a read and write problem.
Going to have a look into this.
Maybe root if i find more info about it.
Thx

I do have kitkat with same restriction.
Other apps can't write in microsd in my device too. I am also using samsung file manager to copy any files to microsd card. But, I can play everything whatever I have.
If you look at your case, other then it's data folder mx player can't write anywhere. Even mx player can't write in DCIM folder. But, it's playing well when you copy through kies means your file is complete. It seems that when you coping from file manager it's getting corrupted or not completely copied.
To copy files there is no need to use kies. When you connect in mtp mode your device will be listed as media device. If you open that it will show both internal & external sd. You can copy to any folder.

Indeed no need for kies.
The issue seems more my sdcard itself.
I have a couple 64gig class10 sandisk here.
Restriction from pc to tab is very bad. But if i use cardreader seems like i can write on the card again.
But i have probs with 64 gig sandisk very strange.
Its like person above said movies are like not fully written on de sdcard.
But I realocated the partion on itand formated it now it seems ok.
So Sdcard was like 59gig partion and 3gig other partion and i scrap and made it only 1 partition in total seems it write much beter now.

ps sorry for bad english

Can't install to sd card. Root access needed :(

I am starting a new topic, because I fear that I am not the only one that is going to have this problem - basically no mater what I do, I can't make the phone (idol 3, 4.7") to install apps to the sd card.
I tested two thing.
Method 1: There is a option in settings -> apps -> preferred install location. I chose "removeble SD card" there restarted the phone and tried to install something -> it goes striate to the tiny less-than-4-GB memory on the phone.
Method 2: Android SDK Tools - after method 1 failed I used the Android SDK tool, to change the default install location using CMD and the "adb shell pm set-install-location 2" command. The location was changed successfully (according to CMD), but when I tried to install something it again goes to the phone memory not the SDK.
Soo... after this didn't work I decide to simply move the apps to the SD card. I didn't have problem with Hearthstone: Heroes of Warcraft for example, but most of the apps actually don't move correctly. For example I installed Asphalt 8: Airborne and move it to the SD card. According to the phone, everything was ok (see attachment 3). Sadly the free space was suggesting something different. Checking with Link2SD Plus reviews a ugly picture - the major part of the app was actually on the phone (attachment 1). Removing the obb files resulted in the game downloading them again... on the phone.
So at this point the only logical solution for me seemed to use the "Link to SD Card" option in Link2SD. Sadly this doesn't work because "Link2SD could not obtain root access" (attachment 2).
I don't know... maybe I am missing something, but at that point the only other solution that I can think about is rooting the phone, witch is not yet possible. If you have any ideas - pls shere.
I am not entirely sure if the problem is connected to Android 5 or Alcatel did something to the OS, but after 3 days of using the idol 3 (4.7") I am on the verge of throwing it in to a wall.

This problem is the fault of Android.
I have the HTC m8 and the problem was the same and no solution before rooting and installing custom roms and special kernels and apps.
I know, very disappointing, but can be solved very easily when rooting will arrive..

Well, then - fingers crossed that we will get rooting solution soon.

Just realized that the same thing is happening with my phone. Looks like I'll use the phone for apps and the SD card for other data. At least my Google play music downloads were saved to the SD card

Sadly I am using Spotify and can't make it save on the SD card.

Same issue here basically, but with photos. I can view, but not delete files using apps such as Solid or ES File manager. They ask to be granted access, but it doesn't work. Native apps like the phone's task manager and Gallery app can edit and delete these files just fine. Other phones such as my S6 and M9 are running the same version 5.0.2 and I don't have this problem. Is it something inherent to this particular phone? Yes, rooting when it comes will solve the problem, but I thought most 3rd-party app developers had solved this issue by now. Why didn't any reviews indicate this problem before I made the purchase? Grrrrr.

In settings, apps under downloaded apps column you can click on an app and provided it's not a google app etc it will have the "move to sd" option. I've used that to move several large apps like wps office (100mb) etc.

You can probably blame lollipop....they've gotten more strict about apps being able to access the external sd card. System apps like Gallery have permission to access the external sd.

I just got a reply from the developer of QuickPic and he says it is definitely a bug they cannot fix. Oh well, don't expect to use any 3rd party apps with your SD card on this phone.

Have you tried using any apps after moving them to the SD Card?
I moved about 6 apps to the SD Card. Then I noticed that the widget for one of the apps on the SD card started displaying an error message (Soundcloud). I clicked on the widget and nothing happened. Decided to reboot my phone and then I realized that none of the apps I placed on the SD Card were accessible any longer. Had to re-download them all again to Phone storage.

You should not be moving apps that have widgets you plan to use. I verified my apps [ Amazon appstore, F-Droid, Lightning Browser, WPS Office etc...] just now and all are working fine...this is also after a couple of reboots since I moved them.

Yep, you can't more the app if you plan to use the widget. That's been normal for a long long time.

Why on earth would Google make it so files can't be deleted using 3rd party apps? That's just dumb. I use both ES File Explorer and QuickPik and this ruins the usability of these apps. hope this gets fixed in an update.

I hope they fix it soon too. This phone only has 10 gbs of internal storage. Putting photos and videos on an SD card is almost a necessity, not to mention music. Other devices running Lollipop 5.0.2 have fixed this. As I said, QuickPic, ES File Explorer work fine on my Galaxy S6 and HTC M9 as regards the SD card. I plan to write Alcatel tomorrow and maybe they will read this forum.

I need someone to check for me please that has this phone and an external sd card. If you would be so kind as to install the free app Quickpic or even the free app ES file explorer. Set the native camera app to save to sd card. Try and delete a photo using either Quickpic or ES File Explorer and see if you get the same result as I did. I'm attaching 2 screenshots. The first one you will see asking for permission and the second screenshot from my phone does not list the external sd card which is the problem.
This will eliminate the possibility that it is just something wrong with my phone or a serious bug that everyone will face. Obviously, if the external sd card is not listed as a choise, you can't grant permission.

I use ES File Explorer - and I got the same prompts while attempting to delete something from the external micro SD card. Honestly - I was not able to exactly follow what it was asking me the first time around. But eventually I was able to do what it was asking me to do ( although I couldn't repeat it if you asked me to !! ) and now I am able to delete files from the micro SD using ES File Explorer.

Thanks. If it now works on your phone, perhaps I have a flaw in my phone. I'll try yet a 3rd sd card and report back.

Solved
PROBLEM SOLVED!! My 64GB Micro SD card was formatted to exFat.
It needs to be formatted to Fat32. I used a guide from this XDA thread:
http://forum.xda-developers.com/showthread.php?t=1773735
Now, QuickPic and ES File Explorer recognize the SD card and permission can be granted.
Whew.

Nice info there. I did the same after seeing your post. I formatted my 128GB card with a 65536 byte allocation unit size which is the fastest. I tested the sd card with flashbench to see which was the fastest. After formatting I loaded a few test files. QuickPic works fine but ES File Explorer still does not. I will delete the data and reinstall the app and see if that works. Right now I'm copying all my music back over to the card which will take a while.

ES File Explorer still won't delete from the SD Card. I cleared the data, uninstalled and installed again. When I delete a file (picture) I do not get the option to select the SD card. Any other solutions?

If QuickPic now will delete from the SD card, so should ES File Explorer. While this was going on, I downloaded 2 additional file managers (Solid and Root Explorer) and they too wouldn't delete from the sd card. Once I reformatted my card, all 3 file managers were able to get permission and delete the files including ES. My only suggestion would be to try reformatting again and if still not working, if you have one, try another card from a different manufacturer. Since ES File Manager now works for me, it should for you too. Let us know if you sort it out. Root Explorer is a very good file manager, but costs $3.99. (Root is not required with the latest update despite the name).

I tried Solid and it didn't work. Then I tried a couple other generic ones and still nope. Then I tried Astro and it worked. I went back to Solid and it worked. Then went back to ES and it worked. Damn so strange but glad it's working now. Thanks for the help.

Marshmallow - write permission on encrypted SD card with 3rd party file explorer

Hi there,
I am using ES File Explorer on my Samsung Galaxy S7. I have noted there is an issue with the write permission with an encrypted SD card. All the new folders I created on encrypted SD card will have an icon with a question mark and I cannot access those folders. The default file explorer that comes with the phone works fine with the encrypted SD card.
I have no problem creating and using new folders on a non-encrypted SD card. Does anyone have any idea how do i fix this?
Thanks

Did you find solution to it?

Email the devs of es file explorer.

I've already contacted the ES File Explorer devs. It seems to me that this write permission issue with encrypted SD card happens to all the 3rd party apps (ES file explorer, MyPhoneExplorer, etc.). The phone just won't let those apps to properly write to the encrypted SD.
I wonder if anyone here having the same issue like me?

I just post a question to MyPhoneExplorer's forum. Hopefully someone there will have a clue of the problem.
"Hi there,
I used MyPhoneExplorer to sync files between my PC and my phones (Samsung Galaxy S3, S5, Note3) without any problem before.
Now, I have a Galaxy S7 (Android 6.0 Marshmallow) and I have noted an issue with the write permission to the ENCRYPTED external SD card. Every time i try to copy/write a file from my PC to my encrypted external SD card via MyPhoneExplorer, it returns an error message saying "Please note: It's impossible to wirte to the external SD card (External storage) for all third party applications due to a security restriction in Android! The internal phone storage (Memory card) is not affected by this restriction. "
Please note that I have no problem copy/write files from my PC to the non-encrypted external SD card on my Galaxy S7.
And i observe that this issue with the write permission to encrypted SD card in Android 6 also happens with other 3rd party app such as ES File Explorer.
So, I reckon the way apps write to encrypted external SD might be changed in Android 6?!?!
Could you please have a look."

Have exactly the same behavior in ES Explorer. When rebooted can see the folder and content. Internal file explorer from Samsung(?) works fine.

I encountered the same problem as well. Happens on all 3rd party apps. Just wondering Is this Galaxy S7 issue only or does this happen on other devices? Are there any workarounds for this issue other than removing encryption completely from SD card?

Have the same problem with every file explorer I tried. the only one that works is the built-in myfiles

I am having the same issue. It seems all my 3rd party apps can't write on SD card. Only Samsung built-in can. I am on G930U snapdragon rooted but no custom recovery. Flashed xposed framework (xposed-v85.1-sdk23-arm64-custom-build-by-wanam-20160530) via Flashfire and installed the Marshmellow SD card module and restarted phone. I still can't delete files from 3rd party app such like a music file within Jet Audio music player. Phone seems to lag now esp when i am on sms. Anyone have any idea on the sd card write permission?

Unable to write data on MicroSD Card after update

Hello to everyone.
2 days ago I received via OTA samsung software update, everything goes well and the update installed succesfully. But yesterday I realized that I was unable to write data on the MicroSD card, my first finding was the camera, the storage switch to memory device when I took a picture, and when I tried to record a video, an error appears and the camera app close.
I tried to create a folder with the file manager but it's not possible, I can't create, edit or delete anything on the SD card, only read. I already tried to unmount and re-mount but not worked for me, also I executed a formating process but the problem still.
The SD Card on the PC works just fine.
Any suggestions to follow?
Thanks in advanced!
Best regards!

Hi. Try to copy all from a sd card to pc and do format in the phone. If the phone will see the card next copy all to sd card. Maybe it help.

bump an old thread, i'm confronting this problem, has a solution been found so far?
i did various searches and found the following links:

this workaround for titanium backup works and it is good
http://forum.xda-developers.com/s7-edge/help/external-sd-card-write-permission-t3341613
but it seemed most of other apps / file explorers with READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE permissions still can't write to the external SD card
note that the stock 'My files' explorer can write / create folders in the SD card, but if u try a 3rd party app / explorer, nothing gets created on the SD card. This shows that it is a permission problem, perhaps "My files" has system permissions and not simply READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE. But that would be 'overwhelming' for a file explorer app to get full unlimited permissions to all resources just to write files / create folders on the external sd card
has anyone successfully made external SD card writable by (older) 3rd party apps simply editing/adding entries in platform.xml?
i tried it didn't seem successful. note that since 4.4 (K) i'd think most apps / explorers has requested READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE. the trouble is that with S7 MM and the recent update. it seemed even READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE is not adequate to write / edit files on the external SD card, e.g. not possible to create a new folder on the external SD card

[BUG] Free space

On my Samsung Galaxy S7 Edge (6.0.1) I use SD card for watching movies. I gave access rights for MX Player and I can delete files from SD Card after I finished to wotch movie. Problem is that after file was deleted free space on SD card was not increased. It remains on the same state. Even If I delete all my files (20-30 gb) free space is not increased. And because of that I can not copy new files via MTP.
But if I delete a small file in Samsung file manager all previously used space became available.
It looks like some flush command is missing.

Might be a firmware bug.
Stock file manager has direct access to sdcard.
Where as third party apps are depends on Storage Access Framework.
If problem persists, kindly try any file manager like fx explorer to delete. If the problem exits with that too, it's definitely a firmware bug. Sometimes Just reboot will fix the issue or it will reclaim the lost space.
