Samsung Devices: External Storage locked after 4.4 updates.

    I've now investigated a bit further.

    I've moved the files back from "storage/extSDcard/Android/Data/com.crittermap.backcountrynavigator.license/files/bcnav" to ExtSDcard and app operations have reverted to normal so I'm convinced that the problems with app storage (noted in my previous posts) were caused by the substantially map data in "storage/extSDcard/Android/Data/com.crittermap.backcountrynavigator.license/files/bcnav".

    Of course moving data back to ExtSDcard caused BNC to be unable to read & write map, track and way points normally.

    I also run Oruxmaps on the same phone (galaxy S4  running 4.4.2) so I investigated this and found that this app allowed map files to be stored on ExtSDcard while tracks/routes/waypoints could be stored on SDcard0. As a result Oruxmaps continued to work normally except that maps cannot be downloaded directly to ExtSDcard. Is possible for BCN to store track/route/waymark data on SDcard0 and maps on ExtSDcard? This could result in BCN operating normally while allowing the use of large map files on ExtSDcard.

    I realise that care would be needed to load new map files but its not too difficult

    a) Switch destination for downloaded map files to SDcard0
    b) Download the desired maps files.
    c) Use a File Manager to move the map files from SDcard0 to ExtSDcard.
    d) Switch destination for map files back to ExtSDcard.

    Would this work?

    Could someone knowledgeable please post how to set my Samsung Galaxy Note 3 storage so I can get on with my horseback riding in the back country? Thanks.

    Has anyone besides me decided that if the files are written to the sd card and you want to uninstall/reinstall, the obvious workaround is to remove the sd card before you do so?

    I have a Galaxy Note 8 N5100 and after latest OS update 4.4.2 my BCN app ceases to work anymore and all my data is stored on internal default setting memory so should be no problem there but app still not working 24hrs after update.

    I have a Galaxy Note 8 N5100 and since my 4.4.2 OS update BCN has ceased to function (not working) and all my BCN files are installed on my internal default device storage so should be OK there but the app is still not working after 36hrs.

    IT WORKED.

    I'm quoting a link that was defined by the poster of this forum:
    " . . . this link from several of you that explains the root fix. We don't know of any non root fix.
    http://www.androidheadlines.com/2014/02/galaxy-s4-note-3-kitkat-sd-card-update-issue-youre-not-alone-root-fix-inside.html
     (top of this forum; first post of this forum)".

    I added notes here below of what I had to do. I did not exactly record what I was doing over this time period since I did not anticipate teaching others how to overcome googles decision on helping rookies not lose their external data... or wt-ever it was that caused that decision.

    If you lack root and have Samsung s3 then this is how I rooted my phone
    I managed to use a "one click" rooting program called "towelroot" version 3 by geohot:

    I had to use various internet browsers to actually get the file to download,
    for some browsers claimed the site unsecure or similar. . .  just google "towelroot", I am sure you'll find it.

    I had to tell my anti virus to ignore the app...
    Had to re-launch the app twice due to anti virus program requesting permissions, and it updated from v1 to v3...


    But the fun does not end there :D

    Within the instructions of the link I re posted...
    there is a file you edit called "platform.xml" ...
    that file's permissions have to be altered ...
    and I'd recommend undoing the permission change once you have completed the change...
    so undo the permission change right before the reboot-part of the instructions (instructions in the link)...

    I used the root explorer called " solid explorer " along with its file editor called " SE TextEditor "...
    The permissions were
    Owner rw
    Group r
    Others r

    I added w to everyone
    Owner rw
    Group rw
    Others rw

    and took those 2 w back before reboot....

    Great App

    Galaxy S4 /Sprint - Android 4.4.2

    Calls, calendar and a few apps for me for me so, I never uninstall BCNAV. Long-name storage option works well. Track Stats got lost.

    Quick question:

    Could you list what Folders are created by bcnav and differentiate which stay in bcnav (on device) and which Folders can go on extSdCard?

    Yes a folder tree, locations and purpose would be helpful. Many of us such as myself are not that computer literate. I love the program and it works well, just trying to understand it better.

    Galaxy s3 and note 2014 edition.. Also, my old phone is a Samsung Charge with spare batteries and I only use it for BC Navigator, camera and wifi internet browsing as cell connection has been disabled.

    Sometime ago I asked
    "I run Oruxmaps (as well as BNC) on a galaxy S4  running 4.4.2,  so I investigated this and found that this app allowed map files to be stored on ExtSDcard while tracks/routes/waypoints are written to and stored on SDcard0. As a result Oruxmaps continued to work normally after Kitkat except that maps cannot be downloaded directly to ExtSDcard. Is possible for BCN to store track/route/waymark data on SDcard0 and maps on ExtSDcard? This could result in BCN operating normally while allowing the use of large map files on ExtSDcard

    Would this work?'.'

    I just installed this app on my Tab4, I was able to move BCN to the sd card, with no issues, whether or not I can save the maps to the SD card also, I do not know at this time, haven't tried yet

    I had no issues moving this app to the SD card in my Galaxy Tab4-7.

    I would like to use external storage. I would back it up using my computer.

    I have a Samsung Galaxy S4. I first noticed a problem with this SD card lock when I used my "My Phone Explorer" program to sync my phone to my PC. I got a message at the end of the sync, when the program tried to execute my setting to delete photos from my phone after transferring them to my PC. The message simple explained that due to the ANDROID security restriction, it could not delete files from the SD card. As I only have 16GB Internal storage on the phone with about 3GB currently available, it is ludicrous to expect me to use Internal storage for pictures and videos. I am left to manually delete imaging files from my phone. I have explored Samsung for a similar program that handles syning automaticly and have been thouroughly disappointed. SideSync is JUNK! Kies is limited. Is there anything I've missed?

    I know this is not a recent post but I suspect you might be able to answer my question.  My Galaxy Tab 3 thinks there is no SD card mounted but that is not true.  Since it doesn't seem to recognize it anymore (it used to) the only Settings option I can select is "mount an SD card".  Is there a way to remove the current one without going through those setting options?  I am not very tech savvy so I apologize if this is a silly question with an easy answer. Thanks for anything anyone can suggest.

    I just purchased a BLU 5.0 C HD 4.4.2 android and it has the same protection problems as discussed above. We were able to root the phone using KingoRoot which uses the developer access and USB debugging function. I was then able to use NextAPP SD Fix (play store) to fix the permissions. It went smoothly.

    Seems like the Developers of BDN just got the short end of the stick from Samsung.  I loved the concept of this program, it is really cool with multiple maps in memory - but the hardware let's it down.

    My Samsung Galaxy Note 10.1 tablet screen cannot deal with sunlight - so it is darn near worthless for my backcountry motorcycle trips.  Now my Samsung S-4 phone's screen is better in sunlight, but I have the above referenced storage issue.

    I guess I will have to stick with my Garmin 64 gps.......really wanted the tablet to work for me in the field.  You get a lot more real estate on the tablet display versus phone or handheld Garmin.

    Sally, you need to check with Samsung support. That isn't an app issue.

    Dave, will you please reread what we have as the basic instructions above.

    Yes, Android (not just Samsung) has messed with the SD Card. But we are NOT saying you can't use it and have to give up and go to Garmin. 

    To sum up, let me be clear. You CAN use the external card on 4.4 but you MUST use the folder name we suggest and you WILL lose the data on uninstall unless you back it up.

    In reply to Sally, If your device does not think there is an external SD mounted then you can just remove it. The Android developers who brought you this problem have done a really good job of cleaning up the system once you remove the card, even if you had applications that were using it. You will only lose your data; not have a corrupted system :) Your SD is probably OK, but the system has found some picky thing about it it doesn't like and won't mount it. You could try another, but ultimately Google or whoever makes these decisions just doesn't want you to have an external SD card. They want to take Android into the corporate enterprise environment, and the external SD represents an insurmountable security risk.
