    How do I restore my lost data? I wish I would have seen this sooner. Last night I updated my gal s4 and poof my waypoints and other trip data seem to be gone. I did store them on the SD card... not on the phone. How can I at least read the data.. or move it back in to see it.. I can't lose this information right now.

    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 have a Samsung S4 also and I suggest a work around would be for the programmers to allow tracks to be saved on internal storage while leaving external storage active for pre-stored maps that have been moved there using a file manager.  Yes it appears to be possible to use all features of the app if you are restricted to internal memory but for stored maps as we have seen, very little can be stored on the S4 internal memory.

    Works for me!   Just upgraded to 5.3.1 .... Galaxy S4  4.4.2 KitKat,  and successfully able to change storage to /mnt/extSdCard/Android/data/com.crittermap.backcountrynavigator.license ....

    **Also was able to copy the internal bcnav folder to the SD Card see previously downloaded maps.  I turned off the "Internet loading of tiles...", and deleted the internal device bcnav folder to verify everything was reading/writing to the SD Card and not internal memory.   All seems working fine so far!  Thanks!!!!

    I had assumed it would have been updated to v4.4, but checking now I see it showing Version 4.2.2. I have been using BCN with external storage for two years now with no prblem, then suddenly last week when I tried to access a map it showed up as .not stored'. A friend of mine who has a Samsung Tab3 had a similar problem - so I assumed it was due to this Version 4.4 blocking access to the external drive. I have changed the storage to the internal drive and it works fine with that, but of course, that doeesn't solve the problem of BCN not being able to access the external drive.

    I have to take back my May 10 post: Verizon just asked me to update my S3 to Kitkat 4.4.3.

    Before doing the android upgrade I checked the procedure in BCN 5.3.3 to set the storage to the suggested external SD Card:  I could not find /storage/extSdCard/Android/data/com.crittermap.backcountrynavigator.license by browsing.  ( I could see other apps' similar folders under /storage/extSdCard/Android/data/, but not one for com.crittermap.backcountrynavigator.license)  Do we have to create that folder or will it appear after I update Android?

    Given the high risk of losing BC Nav functionality after a firmware update to Kit Kat

    but faced with the insistent screen display to do so, either now or later,

    do you know of any way to prevent that update?

    I'm sure Verizon/Samsung/Google will eventually cause the update to happen in

    the background and I'll be in the same situation as the other users

    I'd like to permanently avoid the update until all these bugs are eliminated.

    Thanks

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

    You could complain to Samsung, but it's really a Google issue.  I just bought the new HTC One (M8) and have the exact same problem!  ...and to think I was so excited about the M8 having an SDcard slot (unlike the M7) and supporting up to 128GB... perfect for storing lots of map data files without consuming internal storage, eh?!  It just seems like one piece of this puzzle is preventing the advantages of the other, where they really ought to be working together!  If this is a tactic to force their cloud storage, that obviously doesn't work for this app when we're out hiking and don't have/don't want cell coverage.

    So... maybe the more people reporting this directly to Google, the more likely they'll consider a change??  I just called them and logged an issue with a customer support rep and left a message on the post-call survey.  I'd invite you to do the same: 1-855-836-3987

    It looks like good news for owners of Samsung Galaxy S3's: Samsung is not going to upgrade them to Android 4.4  (I had a scare this week when Verizon issued an upgrade, which turned out to be limited to changing phone network when roaming in Canada)  http://www.knowyourmobile.com/samsung/samsung-galaxy-s3/22140/samsung-galaxy-s3-android-44-kitkat-update-not-happening 

    Nathan; I really like your app!

    David, you might need to contact me separately via ticket, as this no longer fits the thread topic.

    "Not Stored" does not indicate a catastrophic storage failure. It just means that that particular tile has not been stored in a particular map package. It could just mean you have wandered past the limits of what you have stored, and you may need to zoom in or out or recenter.

    It is correct that you can't choose the bcnav folder. It is just trying to stop you putting bcnav inside bcnav inside bcnav. Just choose the parent folder like it says, which is /storage/extSDCard. You are supposed to choose the folder where we put bcnav.

    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.

    Please note:

    If anyone knows how to stop the update, please note it here.

    5.3.0 lets you choose the app private folders that will get deleted on uninstall.

    There are other good ideas here, but please note that they can cause a lot of turmoil (on top of the usual), so we can't promise them instantaneously.

    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 read an article over the weekend about this hot SD card issue with KitKat.  Sounds like it was done for security reasons.  More specifically, this restriction prevents any old app from reading the SD card and pulling info that doesn't belong to them.  However, the article also says "third-party applications — as in ones you download from Google Play or elsewhere — can only write to files and folders that they have created or have taken ownership of". 

    So I wonder if that means each individual app developer can get around this issue by creating a folder on the SD card that only they would have access to for its own files.  If I'm understanding that correctly, BCN could make this available in a future version for those of us on KitKat??

    Hi, just thought I would add a comment. A friend just got an S3 (at&t) and is now using BCN as I told him he should.. He went to change his "Storage Options" but the suggestion did not provide him the long path through Android/data/.... It just gave him a path to the external SD card. And that would not work on his S3. Fortunately I knew what path to have him setup and we got the folder moved to his external SD card with the long one (though Android/data). If however, I had not been around to help him he never would have easily figured it out. Thought I would post this in case there is some way to change the suggested path for devices like the S3. The suggestion on my S4 was the long one so don't know what this means.

    I copied the bcnav directory from my old phone (samsung charge) to my pc desktop.

    just copied the files from the desktop to my new phone, internal storage, directory bcnav.

    (the sd card from my old phone was moved to the new phone and I see a bdnav directory there as well.

    I launch bc navigator but do not find my tracks or way points. I do find stored maps.

    how can I find my old tracks and waypoints?

    Thank you

    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.

    You are probably right. It might take some more tries on our part. Not having the same device here was a limitation.

    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.

    My Samsung Galaxy S3 got updated to Kit Kat 4.4.2 on June 2nd. Now I have my 1st ever problem with BCNAV. Except it is not a problem with this GREAT app. Before the update, pictures, documents, and the BCNAV files were being saved to a microSDHC memory card. No more. Samsung has blocked writing to the memory card unless using an app from Samsung that will copy/paste/move files from internal storage to external. I followed Nathan's instructions and moved my needed BCNAV files to internal storage and everything is working great again. BAD Samsung, BAD. Samsung has blamed Google in the past, so why could data be saved using 2 previous versions of Samsung Jelly Bean on the Galaxy S3 but not the S4? I'm thinking HTC, LG3, or Nexus5 in the future.

    A suggestion which may help with almost all versions of Android on Samsung phones: get a ScanDisk dual USB drive (or similar) and use the drive to save maps and data. You can always restore to the internal memory when needed. Applies to ALL data, documents, photos, etc.

    Keep up the great work Nathan. When I'm on the trails and show this app to people, they are amazed!!!

    We are releasing version 5.3.2. It might be able to find the app private, external storage folder automatically.

    We cannot predict with certainty what it will find on your device, so I am mentioning it here first so you can tell me if anything changes.

    Hello Nathan,

    I just got an S4 (running on page plus, verizon). I installed 5.3.2. I tried to change the directory to the root level of the SD card by browsing (mnt/extsdcard). No go. I then made a folder on the root of the SD card (mnt/extsdcard/bcnav) and tried browsing to that folder. No go. I then went to storage options and selected the default you had setup under suggestions  (/storage/extSdCard/Android/data/com.crittermap.backcountrynavigator.license/files) and it worked. So the question, is this because of the new security issues must the folder be put in Android/data on the SD card? And therefore, is there no way to put the bcnav folder at the root level?  

    I just have to say it again, this is a truly great product and it really does the job. I commend you!

    What version of Android does the Samsung Tab 2 have?

    Also, per above:  "It is possible that we could write to "/storage/extSDcard/Android/Data/com.crittermap.backcountrynavigator.license". However, it has some dangerous implications. The files cannot be seen outside the app." .....   

    fyi, I have no problem seeing these files/folders outside the bcnav app, and I'm non-rooted.     I'll just remember to backup that folder before doing any uninstall/reinstall of bcnav.   Maybe a simple 'warning'/pop-up when somebody chooses external storage location would minimize any upset users who lose everything on an uninstall/reinstall because they didn't manually backup that folder.    I'd also just disable the storage location feature in the DEMO version so you don't have to worry about folks wiping anything out when purchasing the Pro version.    (plus would be a good upsell feature to Pro).

    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.

    Hey Nathan,

    First of all, I love Backcountry nav.!  But is there anything new on this issue?  I'm trying to setup my new S5 and can't get it to use the external SD card.  From other sites I've read that the 3rd party developers can get around this problem now? is this true? and when are you guys going to use the Fix? I also don't want this to mess up my Galaxy Tab3 if they update to KitKat. Have an awesome outdoor weekend! Thanks for any info.

    The trial version is not going to let you choose it. Also, we cannot find that folder until Android 4.4 is installed, because the query didn't exist before. Other than that, I am not sure.

    Just one additional question. When I browsed it showed "mnt" not "storage." If I typed in the path as /storage/extsdcard/bcnav I wonder if it would work. We can't type the path, but thought I would pose the question. Thanks for your response Guthary. I'm just going to stick with what works.

    I've transferred my map files to "storage/extSDcard/Android/Data/com.crittermap.backcountrynavigator.license/files/bcnav" as suggested and BCNav now works fine.

    However there seems to be an unexpected consequence - any app (just to be clear ANY app) uninstall takes about 5 minutes. I have 46GB of map data and suspect the delay is caused by 'uninstaller' checking "storage/extSDcard/Android/Data" for any files that need to be uninstalled at the same time as the app.

    Has anyone else had this problem and does my explanation make sense?

    Does anyone have any suggestions to reduce this problem other than reducing the amount of data I use?
