My experience setting up Atrix file and folder security

I was considering storing financial and personal information on my phone in the form of files and realized that though the fingerprint scanner is ok to prevent the casual browser from logging into the phone when it is left unaccompanied, a real hacker could easily see whats on there with very little effort.
The Atrix on the face of it looks like a secure phone with the fingerprint reader; however XDA users would know that nothing prevents a thief from entering fastboot and mounting the files and folders to see whats on there. No security app can prevent that.
Using the android built-in option and encrypting the entire sdcard is NOT an option for me at this time. I think its going to slow down the phone operation if the OS files are encrypted and each time it needs to decrypt each and every file and folder. Also it may present issues when testing new ROMs. (And I am dual booting - so my extSD also has a ROM which I would not want to slow down anymore than it already is)
So I searched for methods and apps to encrypt individual files or folders on the Atrix. There are quiet a few in the market and a few are free as well with good reviews. However most -even the ones with the best reviews seem to be just changing the file name and location and not doing real encryption. Also most of these use proprietary algorithms or methods to hide information. A really good app would be one that uses an open source algorithm to encrypt the files and folders - so that the algorithm would be tested and verified as being strong by the world.
Also another requirement was for the ability to frequently sync and update the files on the phone with the PC. The app should have a PC equivalent - that is the file can change on my PC and then I should be able to sync the changed file with the phone in some automated way.
Yet another requirement would be the ability to quickly encrypt and decrypt huge audio or video files. A few good apps could encrypt small audio and video files but not files of size 1GB or more. The apps would either freeze after some time or not encrypt them at all.
Finally I was looking for an option by which the files if I unencrypt them to be available across all apps for the duration of that session - not just in the app that encrypts and decrypts them. So in other words, once I enter the password, the folder should be mounted and available in any app that can browse the phone - until I decide to end or unmount the encrypted store.
I found only Cryptonite doing all of this. Unfortunately Cryptonite does not support Truecrypt containers on Motorola phones. There is some info here on the truecrypt port to android here:
http://forum.xda-developers.com/showthread.php?t=872297&page=7
However I could not get it working with the Atrix. Has anyone had success getting Kryptonite and Truecrypt to work on the Atrix?
Cryptonite also supports Dropbox, but I am not a big fan of storing sensitive info in the cloud - however well known the company is.
Cryptonite does support encFS and I was able to successfully create encFS encrypted folder on my Atrix. I would have liked to have TrueCrypt than encFS, just because I have been reading that Truecrypt has better overall support.
The method I use now for storing and synching encrypted information is:
for the first time only: create the encfs folder on the PC, then mount Atrix as a USB drive and copy the encrypted folder to Atrix.
To sync the encrypted files with the PC, I have to connect the Atrix as USB drive, open EncFS on the PC and select the folder on the Atrix to mount as a drive volume. Also mount the PC encFS folder as another drive. Now sync with the PC using any sync tool like MS SyncToy.
I went through a lot of searching and came to this which I think is good enough at the moment. I would like to hear if anyone else has a better app or method to secure and sync secured files on the Atrix - especially if you have got Truecrypt to somehow work on the Atrix. And I post this so that is anyone else needs this information, it is here.

I don't know about the rest of it, I never used any strong security on my phone nor do I intend to, but I think you shouldn't ever expect to be able to "quickly encrypt and decrypt huge files". You're pretty much asking for impossible here. It's like asking to build a full-featured house, furnished and all, in 30 minutes or less. A lot of data will always require a lot of time to process. Heck, even, say, straight plain copying such a file to a computer would take quite a while.

No.
Your not going to get business class security on your atrix, or any current phone most likely.
LUKS manager is the closest thing to legitimate encryption (not gimicky BS) i have seen, but it has some fatal flaws.
Passwords and such are safe and easy to store with KeePass, which is also on windows/linux for syncing and has years of reputation (also free/open source). It isnt for files though.

[Q] Sharing apps and media files between users

Hello,
I've tried to search but didn't find an answer...
I've just got my N10. I want to have two profiles: one for myself, the other for my wife.
The problem is the apps I installed on my own user are not shown on my wife user. I don't want to install twice every app. In addition, I don't want to pay twice for payed apps both my wife and I want to use.
Same problem with media files: pictures I took on my user are not available on my wife's user gallery.
So, my questions are:
1. How can I share apps between users?
2. How can I share media files (photos, music) between users?
Thanks in advance!

Hi, did you find an answer to this? Same problem.

Hi,
1. I've found out that if an app is installed for one user, then when I install it for another user, it doesn't really get installed twice, but uses the same installation. It only makes a separate folder for saving app related data for the other user. In other words - the app is installed only once, but users have their own data, settings, etc.
2. I've also found out that I can define play store on the other user account with my own google account. That means that my wife has her own gmail and all other google things, but the play store on her user is defined with my own google account. By doing that, I solve the payed apps issue - they appear for both of us as already payed and we can just install them on my wife user without paying again.
3. As for shared files (pictures, movies, etc.) - Unfortunately, I didn't find any solution. I still hope that someone can help me with that.

Thanks for the reply Animor, really helpful.
Para 2 makes sense to implement, particularly when I have purchased apps specifically for the Nexus, at least I don't have to buy them twice!
The shared files problem is a bit of an issue, I should be able to share music and photos without having to double up on valuable storage space. Any fixes for this welcome!

Try putting a couple files in /data/media/obb/ and see if all users can access them. If I recall correctly, the purpose of that directory is sharing files between users.

Thanks, but I didn't find this directory on my Nexus 10...
However, I've got a solution from another forum:
Directory /sdcard/android/obb/ can be used to share files beteween users. Basically this directory is used by large applications, but it can be also used for sharing files by adding directories or files there.
It doesn't require root, btw. All users have direct access to it.

Maybe put the shared pictures and whatnot in a Dropbox folder you share with your wife?
Not the exact solution you're looking for, but it might fit your specified requirements.

Thank, but using dropbox is not necessary since I've already found a solution.
As I stated in my previous reply, /sdcard/android/obb/ is common to all users, so I just put there everything I want to share.
Thanks all

Answer
Try using 'SendFile'...Its available on the playstore....very simple UI and u can share any type of file between mobiles and PC's....what attaracted me was the fact that u dont need the app to download the files.....

Just updated Nexus 4 to Lollipop and got excited with the new "multi-user" feature.
And following your suggestion, I managed to share files between users.

wifi direct FOLDER transfer between phone and tablet.

Hello everyone,
I have found many apps for transfering FILES but I have yet to find an app that allows me to transfer entire folders via wifi direct.
I race cars and run a data-logging app that allows me to go over each run, see where I sucked and where I did well. I start each event by creating an event name and the data logger stores all files pertaing to that event in its own file.
In between runs, I have a little time to analyze the runs and try to "find time" on the track.
I have been doing this on my phone but my wife just got me a galaxy tab3 10.1 so that I could see more data at once and read it all easier.
The 10.1 is indeed easier to read, but it's rather large. Rather than try and find a way to mount this beast in my car while I race, I would rather just run the app on my s4 and shoot the log folder to my tab for review.
The folders are not that big but the contain many small files that are named in a way that allows the app to pull all the data together in an easy to read interface.
Wifi availabilty is hit or miss from venue to venue so I don' want to depend on a router. I hope to connect the two devices vi wifi direct and send the event folder to my tab....then open the app, select the newly dowloaded event, and go from there.
If there is a free app that does this, that would be great, but I'm willing to pay for an app if I need to.
TIA.

Kit Kat 4.4 and external SD cards

I have read and I like the new restrictions on "external SD card" use. It will prevent a lot of apps from leaving crapola all over your device.
It does not restrict your use of data etc. It just keeps you organized. If you want to uninstall an app and still keep its data, you can simply move the data to a new folder.

True - I only root my devices when they are out-dated.
I don't think the 8013 has reached that point yet.
I am still happy with its performance.

But what I am understanding is apps are corralled to their own folders. This implies to me that some I rely on will cease to work. Example:
I use folder sync to keep lecture notes synced between my 10.1 and S4. By my read of KitKat, folder sync will be prohibited from writing to the lecture notes folder.
What about photos? Different apps to adjust photos depending on what I want to do.
And what about ES File Explorer. Won't it become useless?

There aren't. I've had KitKat since weeks after release (S4 GPe). I've been in touch with many developers and made them aware of the issue before it went mainstream. Bottom line, here's the limitation in the simplest of terms.
-An app can read any file on the MicroSD Card.
-An app can only modify contents within a self contained subfolder
So, file managers won't work if stock and unrooted (read only, no writing). FolderSync doesn't work. ES doesn't work (it will tell you that it created/deleted/modified the folder, but then when you refresh, the change never happened).
A good example of how this works would be with a bare bones gallery application. If you store your photos in a random folder within the SD card, the Gallery app can view them. However, if you try to delete a picture, it will only remove from the gallery and remain on the SD card. After a device reboot, it will reappear in the gallery (this also happens with Google Photos and the stock Gallery app).
Another way to do this would be for the gallery app to copy all photos to the gallery subfolder and ignore photos outside of this folder. And if you remove the app? Photos are gone (except what was at the original location). But, this just causes duplication issues.
Lastly, applications can be given permission to read/write to VERY specific ContentProviders and folders. So eventually, you'll have a shared folder called "Pictures" that any gallery application can modify as needed. However, this function is, again, for very specific usage and still prevents file managing apps from doing what they're intended to do.

Seems like the android team need to add some sort of "firewall" implementation, for apps users WANT their old ability back and still provide their users with this security for the majority of their other apps, it doesnt have to be all or nothing, .......make the most secured option as default, for basic users, while giving the power users the option to "fine tune" it, i.e. the "firewall" analogy

Just to be clear, if I write an app and want to write (not modify) to an external SD card I must write to the self contained folder.
Is that correct?

I don't see how you think it doesn't restrict a user's data but keeps the card organised, when I have all my data (a LOT of work PDFs and docs, plus some photos), all nicely filed away and synchronised with my NAS, and other tablets; and now I cannot do this. I cannot organise my content at all (actually I am struggling even to put it on the SD card, except by taking it out out plugging it into a USB adapter into my PC). Until now, I have never had any apps leave crapola on my SD card. I used to be able to save lecture recordings direct to a nice "recordings" file on the SD card. Now it has to put it somewhere obscure (android/data/.somthingrandomthatisapaintofind).

It seems this works on some apps and not on others. For example foldersync doesn't seem to be able to write to the external sd card anymore, nor does X-plore, however, Es file Explorer seems to be fine about it, and happily writes files to the sdcard?! So if ES can do it, why can't the others?

I see - you are just using the USB cable I assume. The functionality I have lost is to:
a) wirelessly synchronise multiple pdf/document files in multiple folders and multiple subfolders, whether edited on the Note or on PC (or both).
b) Used a file management app to organise files & folders on my home network between my PC and external SD card. It was even able to wirelessly copy my work direct from the NAS.
None of the apps I used stored any files on my SD card and because they have taken away my access to my SD card I cannot sync my files properly. I realise I could just plug the cable in, but that is not practicable when I am editing 100s of documents in 100s of different subfolders a day - an automatic sync is fantastic. Android is strongly geared towards the "leisure" side of the market and I am going to have to take another look at Windows tablets if they don't fix this (except I would miss the S Pen!)

What device are you using that can write to SD using ES? I have the Galaxy S4 GPe (i9505G) and ES cannot do anything with the SD Card.

Have you updated ES? I heard they upated to fix it.
As I understand there is something called storage access framework that is supposed to be the replacement for direct file access.
I haven't seen kitkat. FolderSync is my biggest concern.

I'm on a Samsung galaxy note 3, with kitkat 4.4.2 and ES file Explorer 3.1.1

Yes, thanks to a post somewhere on XDA I am now using ES file manager, which as you say, will work with the ExtSD on Kitkat (though I still prefer Astro myself).
I still can't sync my content though which is the bigger problem. I used to use SyncMe. A fantastically easy to set up App that would seamlessly sync content across multiple devices (still works fine on my Note 8). I can't find anything to replace this at present.

[n00b Guide] - Fire for Christmas ::for Kids::

I've spent the past 3 weeks pretty solid working out how I want to transform the 3 Fire's I got for $35 for my boys, 10, 8, and 4. I figure I'd post where I've finally landed along with some other things I've tried both with success and failure, and hopefully save some people some effort. I'd suggest reading through this before you use it as a stepbystep guide to make sure this works for you. I apologize if it's a bit jumbled, but everything should be here for you to convert your Fire. Again, I'd suggest reading through the whole thing to come up with a plan of action for you.
Goal: Turn this Fire into a glorified gameboy, used ONLY by kids, not shared with parent(s) and child
On 5.1.1
Assuming you've purchased an SD card, you will want to repartition in preparation for moving files and content.
Pointers for this:
Make two partitions, 1 which is about 70% of the card formatted as Fat32, must be a PRIMARY partition.
Second partition will be the remaining space, make it ext2, must be a PRIMARY partition. (From what I can tell the reason people suggest using ext2, and not 3 or 4, is because with 3 and 4 there is some built in backup and recovery operations which is great for when you're running a full Linux operating system, but for our purposes all it does is cause more writes which in THEORY will shorten the life of your SD card)
I formatted the Fat32 partition as the first partition, and the EXT partition as the 2nd. Not sure if the order matters or not, but I've had no problems doing it this way thus far.
Reference: http://rootmyandroid.org/increase-internal-memory-phone.html/
Reference: http://rootmyandroid.org/how-to-use-link2sd-tutorial-guide.html/
Note:
During initial setup, don't bother with multiple user profiles (reasons explained later).
Using root junky's super tool (Thanks root junky, you made this all possible!!! http://rootjunkysdl.com/?device=Amazon Fire 5th gen&folder=SuperTool) do the following:
Root
Prevent OTA
Install Google Play
Install NovaLauncher (this is important if you're not going to use the built in Kids Mode in FireOS)
In Google Play Store download the following:
Link2SD (This is assuming you've purchased an SD card)
Kids Place - The VERY SIMPLE reason I went with using this app (which essentially becomes an alternative launcher) instead of using the built in FireOS's profiles and kids mode, is because the built in kids mode will ONLY allow you to use apps which you've downloaded FROM the AMAZON app store. I understand why they do it this way, I mean, the whole point of the fire is to keep you inside the Amazon ecosystem after all. But, I have MANY games I've paid full price for on Google Play that are appropriate for my kids. Since I can't put them into the kids profile built into the FireOS (If anyone can link me to a guide which is different, I'd love to hear about it) I couldn't use the built in stuff. In addition, the built in kids mode really is a pretty awesome feature on the fire, but the icons are freaking huge and kind of a waste of space.... going with this alternative method of Kids Place gives you smaller icons therefore you can "shove" more icons on a single view. Icons which take up half the screen are great, but if you're a dad like me who's going a little overboard and putting 100+ games on these things, it'll be a bit of a pain to scroll through them for your kids using the built in profile in the OS.
Note:
You can get Link2SD from the Amazon app store, but the version there is older than what's in Google Play and ultimately didn't work. Once I got the Google Play version, worked like a champ. NOTEx2: For whatever reason (this was frustrating for me to figure out), even though I partitioned 70% of the 64GB Samsung microSD to Fat32, and the other 30% I partitioned to ext2 (BTW I did the Fat32 first and ext2 second... not really sure if it matters the order or not but that's what worked first time for me so I went with it), when I launched Link2SD and it asked me which partition to use, I had to choose ext4 for it to finally work. Choosing both ext2 and Fat32 would both result in basically it saying: "yeah, you chose the wrong one punk" (or whatever it says).
Kids Place - similar to the one above, there is weirdness in the version on Amazon vs Google Play. On Amazon it actually claims the version there is slightly newer than Google Play, but when I'd launch apps on the one I got from Amazon it would kill the WiFi for that app. I realize that this is a built in option into Kids Place, being able to choose WiFi on or off per app (which is really cool), but the one from Amazon seemed to do it when and how it wanted instead of what I was telling it to do. Google Play's version had no such problems.
(( A word of caution using Link2SD's "feature" of being able to "Link Internal Data". DON'T DO IT. I've not been burned HARD CORE by it. The symptom is that if you POWER DOWN, and POWER ON the tablet, Apps go missing. Through reading and troubleshooting, it appears via this forum (http://androidforums.com/threads/link2sd-missing-apps-after-reboot.858565/) that the culprit is when you choose the Link2SD option to "Link Internal Data" to the SD Card. There's even a nifty batch way to enable it on ALL apps. Well, after powering off and powering back on the tablet (after I was COMPLETELY done putting on 150 games), when it came back up I only had like 15 apps on it. Everything else was POOF, gone. I've noticed sometimes after a power cycle like that the apps might take a few moments to 'come alive', but even after 15 minutes of waiting I had nada. Went in search and found I'm not the only one. I've now since completely redone (including reformatting the SD Card) all 3 Fire's and so far after multiple reboots, I've not lost a single app. So for now at least, this does seem to be the problem ))
You will need to spend the $2.35 on Link2SD Plus (striking out due to my caution above, that being said I'm glad I threw this guy $2.35 because my tablet would basically be worthless without the app), and after you install Kids Place, you'll need to upgrade to premium for $4.99. Here's why:
Link2SD - Plus - This is what allows you to automatically move files and content to the SD card when an app is installed. This is mega important to me because that piddly 5.x GB of usable space gets eaten up ridiculously fast otherwise. Dive into the settings once you have plus, and just go turn everything on. Auto move everything. Be sure to go into all menus and sub menus.
Kids Place - The premium features is key for me. For example: A) You can make this app launch upon reboot, thus it basically "forces" this into a kid only/friendly device. If your kids are sneaky, or bored, they'll try to break out of Kids Place. Then they'll delete apps, make folders, sabotage they're brothers devices, etc. B) You can change the name that's displayed on top from "Kids Place", to something else like their name, give them a fun nickname, whatever. For my 10 year old he won't feel like it's just a little kid thing. C) You can do this part without premium, but it's critical for me to mention it: You can change what the home "button" does so that it directs you back to Kids Place instead of the regular home launcher. The reason you need to install NovaLauncher above is because if you still have the stock firelauncher, you can NOT replace the home button with another launcher otherwise. [Word of caution, if you enable the 'background' premium feature, Kids Place is still running, just more in the background. Took me a few minutes to figure out that's what I had done. I kept thing something was wrong and wondering when whenever I launched Kids Place it kept asking me if I want to shut it down or go into settings.... it's because it was running the whole time already)
Once you've done all that, simply download apps (Amazon Underground still seems too good to be true, but I'm hopeful), sideload apps, get apps from Google Play, then go into the Kids Place settings and choose which apps you want (Manage Apps).
Other things worth noting:
SlimRom. So, this is cool. It's fast, and pretty awesome. For me however, at the end of the day, it didn't make sense to introduce something in addition that could go wrong. If you're like me and you have no intention of using this device yourself and you ONLY want this to be a device for your kids, I don't think SlimRom is worth putting in. If it's a shared device, it might be worth it. The only thing I really forgot to test when I had put SlimRom on one of the devices was how the Amazon App store would work, and whether or not the device would be recognized properly with the Amazon Underground portion.
That's it, I hope you find this helpful. I welcome any feedback or suggestions on how to make this a more gooder guide for anyone like myself who's first jump into amazon tablets has been these fires. They truly are AMAZING devices for the price.

Seems pretty comprehensive guide for those using it the same way, very nice work
And when I had Slim on it worked fine with my amazon app store and underground apps. And the music and video ones for that matter. I couldn't get the kindle app to show my books but someone solved that by using older apk after I went back to stock.

@hobojester, THANKS so much for posting.
I purchased the $35 Fire Tablet for my 3 girls (9, 7, 5).
I've rooted at 5.0.1 and disabled OTA, disabled ads, Installed GooglePlay store, and loaded Nova launcher. Although I haven't taken it another few steps with Kids Place, I feel that I'll start with just locking down and hiding the apps via Nova Launcher will be enough for now. My kids are pretty savvy at navigating interfaces and even when they touch/exit an app, they know how to get back to it. I know there are holes with settings and NovaLauncher settings so when they figure them out, they can reenable certain functionality.
I'll look into Kids Place though, that might be my next step.
Also, about the whole SD card partitioning, I've installed a 32GB card and the tablet stated that it would start using the card as the default storage device. I'm guessing your method moves EVERYTHING to the card, and the default behavior for the Fire Tablet is to install some things on internal memory and 'other' storage is routed to the card? I've installed quite a bit of applications since I plugged in my SD card and it doesn't seem to be full... although I didn't check the storage stats before I wrapped the tablets.
Also, I've heard some good press on the Circle (with Disney) router, so I did order one for the home as yet another piece of the parenting puzzle:

Good to know about Slim and the Amazon store. Again, if I were going to use the tablet in a 'shared' environment where I'm using it AND my kids are using it, I'd totally use Slim. It was awesome. In this particular instance where this $35 device is a glorified gameboy, Slim is just something that is an extra layer of complexity that's really not needed and *could* get in the way. I have no intention of my kids even getting on the internet with this device. Not until there's a real need, and even then, I'd probably go get the K9 browser and use that.

Glad you can find this useful.
As far as the storage card piece, you are correct in that "my" method moves EVERYTHING. Some apps are "self contained" as I like to think of it, when you download it. Popular games like Geometry Dash have everything contained in the downloaded app (or the .APK file). That is just the app itself. You can tell the OS to auto put the "app" on the storage card, and that works out great, but it's a little misleading. The problem comes in when you have games like Knights of the Old Republic. That app itself is something like 40 MB or what not, but after you launch the app, it'll download this extra content, which in this particular case is 2 GB. The kicker: it'll ONLY store that "content" (as I call it) into what the device considers "External Storage", which is ACTUALLY on the INTERNAL storage. That whole emulated SDcard business Android does. It's all funky. For fear of sounding like a commercial, Link2SD fixes all of that. Linux (what Android is built off of (oh, and hi iPhone users, so is iOS for the record)) has this thing called "Symbolic Links". You can google it up more about it, but think of it as an uber shortcut. You create a symbolic link on internal storage to the actual physical SD card, and the program THINKS it's writing to internal storage when in fact it's writing to the SD card. The kicker: you can only create symbolic links if you're rooted. The nice thing about Link2SD, is that it'll symbolic link EVERYTHING. The "app", the "content", and all of the saved game data and what not (which take a game like MineCraft, can get pretty big if your kids (like mine) go crazy building worlds). And you can have it to it all automagically. But you will need to pop that SDCard out, put it in your computer, and get it re-partitioned (visit the links I posted in the original guide for more in depth details).
I have heard really cool things about the Disney router. For now, my kids don't really have any need (or business) getting on the internet unsupervised. When they do, I'll probably give them the K9 browser.

Sorry for the questions but I can't figure it out, searching doesn't find it, and I'm trying to get these wrapped.
Do I need to still select Fire OS" install supported apps to sd". Or do I do it all with LInk2DS? I haven't Rom'd these yet and I probably won't until we get back from vacation. They are only rooted with stock rom. I also don't need to do the whole kids place thing as my kids are a little older...Thanks for taking the time to write this all up!
Also I have partitions shown in my Disk usage app that are named "External", "SDcard1", system and "SD Card". I know "SD Card" is the exfat 2 part I made base on the size, but as for the "external" and SDcard1, they are both roughly 5 gb ( my sd was only 8 gigs so I made the FAT 32 5 gigs and the rest the exfat 2. But now I am not sure of the naming and I can't tell based only on size. So, is "External" really the built in amazon storage, and "sdcard1" is my microsd?

Like your thinking.
How are you getting past the "Apps with usage access" request for Kids Place?

This will be a good chance for me to point out (I'll edit the guide in a second): DO NOT LINK "INTERNAL" Data via Link2SD. It has caused apps to disappear and never come back. I actually had to start completely over on all there of my devices. That "option" to Link the Internal Data is only available when you purchase the Plus version of Link2SD, DON'T CHOOSE THAT OPTION!!!
Now, with that out of the way, Link2SD is clever in how it works, and I am barely out of the n00b stage on this so I'll give a disclaimer that I may be totally feeding you false information here, but here's how I understand it: First of all, what I did was leave the SD card settings inside the OS all 'defaults', which installs the "App" to the SD Card. Now with that, I believe what happens is Link2SD intercepts that 'transfer' and puts the actual apps on the EXT partition. There is the incredibly critical option in Link2SD to put all other data (except "internal" data of course) on the SD Card. That's what moves the really big parts of those big games and apps. So when the App is relocated, it's put onto that EXT part and the Content on your FAT32 part. To address your question regarding External, SDCard#, and 'where in the heck is the EXT' part.... the EXT partition is mounted and 'located' under the 'local' storage under something like the /data/sdex2 folder. Welcome to the world of Linux... on a computer Linux (if my really old dusty Linux knowledge still works) when you need to access the CD drive you have to MOUNT it, and than LINK that mount to basically a local folder (something like /MNT/CDROM). Your EXT partition is mounted the same way as a folder, and for whatever reason in an app like ES File Explorer you won't see it as another drive, you'll only see the FAT32 drive. Maybe that has something to do with it being FAT32, I'm not sure. ...... the long point here is that Link2SD intercepts or coordinates with the OS's moving of apps to locate the App data to your EXT partition (mounted to that /data/xxxxx folder) and all the other really big stuff to the FAT32 partition. Again, I may be way off here, but hey, makes sense in my brain right now .
Inside of Link2SD there's an option in the menu to see the storage consumption, and THERE it'll actually show you the EXT partition as well as the FAT32 partition.
If my kids were a little older and I truly didn't care about them mucking around in settings, potentially deleting things etc., I'd probably give SlimRom a go for that. I've been messing around with it some more and it is just simply more 'pure' Android OS so it'd give the more 'true' Android experience.... if you really care .

I'm not, simply because FireOS doesn't have that option. I just have to hit 'Cancel' and move on. If you were to put on SlimRom you'd have that option. From what I can tell the biggest thing we're missing out on by staying on FireOS and not having this option would be limiting time in Kids Place for certain apps and what not. For me personally, I'll just set a timer, but if it's something you want to use, I'd absolutely suggest putting SlimRom on there and then basically following the rest of the guide. Everything still applies.

If anyone cares, I set up SlimLP for my mom who is a bit less technologically advanced than I am and I put smart launcher on the device and just hid the apps I thought would be bad if she were to accidentally open them and not know what she was doing. (I thought his could be useful for some of the people here as well)

How do I avoid using the "Link Internal Data" feature? I do not see this option anywhere in the App.
Edit: OK. found it. I was looking in settings (before moving anything) but once I move an app the options come up.

Yeah, I found out the hard way how bad this can be.... like... 6pm on the 24th, type of thing, RIGHT when I had finished it all up. I had some kind of heavenly help nudge me into thinking "you should turn these off completely, and simulate Christmas morning, see how long it'll take to fully boot back up".... and you can imagine my stomach drop when I went from having 150 games down to something like 3... it was painful. So, yeah, avoid that setting AT ALL COSTS!

How do you partition the SD card on the tablet? Also is this worth doing when you can install xposed SD card modules and be able to move obb files

just wondering on the reason for 70/30 FAT32/EXT2. What gets installed in each partition?

I"m not familiar with the xposed SD card modules so I can't help there. As far as HOW you do it, I linked to some articles in the first post that might help (Reference: http://rootmyandroid.org/increase-in...ry-phone.html/

Basically the "app" gets installed to the 30% EXT2, and allt he "content" goes tot he 70% FAST32. Content will typically be data that gets downloaded after the app is installed. Take Knights Of The Old Republic for example, the "app" is like 50MB, but the "content" which gets downloaded upon the first time launching the actual program, is 2GB.

An Alternative Solution
I also gave my kids 3 Fire tablets for Christmas. My kids are mostly older (12,11,4) and the older two have had other Android devices. I went a different direction from the OP, which I'll discuss here for posterity's sake. This is a bit harder than the OP's method but ends up with a more conventional Android environment.
As background, I used FireOS on the Fire Phone for a few weeks, and ran into many problems. I installed CM11 on the Fire Phone and bought another in the final sale. You can read about that on the Fire Phone forum if you're interested.
Also, I've used Screen Time Parental Control for a couple years now, and while somewhat expensive it's great for monitoring without being too invasive. I can let the kids have a lot of freedom with their devices, without having to be worried about them either being on them all the time, or doing weird things. Screen Time nominally works with FireOS but in the end I did not use the tablets as-is long enough to try installing it.
For these tablets, I decided the easiest path was to install CM12. This avoided waiting for Amazon for security updates, and any FireOS incompatibilities, as I'd experienced with the Fire Phone. Also, the kids are familiar with CM, and frankly any replacement Android device will be easier in the future. After my experience with the zombie Fire Phone from Amazon I'm less concerned about CM/ggow/XDA bugs than I am Amazon's.
I decided to create separate user accounts for each child, as opposed to having both my Google account and the child's Google account** under a single user. I've done this before, but it's awkward to have to switch between accounts when using Gmail/Hangouts/Drive/etc., and sometimes things get mixed up.
Thus, for each of the three tablets I went through this process:
[I don't have the tablets in front of me, so if one of these steps doesn't seem obvious ask and I'll look up the exact names/buttons.]
1) Install CM12 using the well-documented methods
2) Boot into CM
3) Configure for my primary Google account
- Download interesting applications that have been purchased on my account
- Open SuperSU, enable multi-user access
- Open Contacts, select "ME", change name to "Dad" (or whatever)*
- Open File Manager
- Settings / Enable multi user access
- Open main Settings app:
- Set screen lock / PIN
- Users / Add user / OK / Set up now
4) "Switching to new user"
- Google Launcher always
- Log in with the "child's" account** in the wizard
- Open Contacts, change "ME" to the child's name
- Open File Manager
- Settings / Switch to Root access mode
- Browse to /data/app/
- Change into interesting packages and pick the .apk file
- Select "Install"***
- Repeat as necessary
Here I installed Screen Time Parental Control from the Play Store and went through the steps for Child device. Also any customization for the account should go here, then you can switch back to your regular user.
To switch user, drag down the system tray, pick the head image in the top right corner, and then the appropriate name.
Notes:
* This is in a wacky place, but this contact is how CM identifies the user name to display in the switch screen. If you don't see "ME" don't add it, just browse around; it's there somewhere.
** Apparently Google only allows accounts for people >=13. Thus, if you are reading from Google, know that these are my own accounts and my children happen to use them.
*** This will actually not re-download the application, but it makes a temporary copy while installing. Application user data is always separate between users, but for the most part download data is shared. For most applications things work on either user; however, Electronic Arts applications don't work with separate users, and Terraria will print an error (but still worked once the core data was downloaded with my purchasing account). I'm sure there are other apps that roll their own security and will be in this situation, but out of a very large family library these are the only apps with which I've had trouble.
Finally, a last note that Screen Time does not presently block creating new users from the system tray. In theory a youngling could create a user that would not have Screen Time limits, but then they wouldn't be able to delete it without getting in to Settings, which you should block anyway. Depends how devious your children are; for me I'm just waiting until they figure it out to do anything about it... just keep an eye on it if you go this route.
Hopefully this helps someone, eventually!
Best,
Tim

I got two fire tablets for the kids for Xmas, one is the kids edition (with the 1yr of apps,etc) the other is a standard fire. Used root junkies tool on both to block lock screen ads and OTA and hide Apps. They were both running OK, occasionally have the odd situation where you try to open an app and it looks like it is reloading it or redownloading it, not sure if this is because internal space has ran out and its redownloading on the fly but its quite frustrating.
Decided to flash slim LP rom on the standard tablet as there were apps that weren't available(better choice on play store and it wasn't tied into the 1year subscription).
So glad I did, was pretty straight forward to get it up and running and the latest build is so solid, fast and stable, was expecting it to be a bit quicker than fire OS as it had a lot less bloat but it seriously impressed me. So I have kids place set up on it to control apps and play time. I also installed hilocker from the play store to help simplify/lock down the lock screen. For example you can disable the status bar in kids place,but the child is still able to turn the screen off and on, they can then access the pull down toggles and mess with things, but with hilocker you can disable it which is great. Battery life is just as great if not better and your also up to date with all Google's security patches to boot.
It is a very good value tablet, as its just been reduced to just £40 in the UK. One thing that would be a major improvement is I just wished they had put 16GB of storage instead of 8GB. I know it has the sd card option which is great but in reality you only get around 5GB of actual internal storage for apps, a lot of which can't be moved to the sd card or still take up internal space when they are. Again I can't recommend slim rom enough as it really makes a big difference to the tablet (besides providing full play store access) and makes it perfect for consuming media, browsing, or just handier for when you want to use a bigger screen than your phone.

@gsmyth, look into Link2SD if you haven't already. Between that and a 32GB MicroSD I don't feel especially constrained by the 8GB onboard.

How are you formatting your 2nd partition for links2sd?. I keep getting 'unable to mount' error, trying to setup as ext4, which I thought was the standard on newer hardware. I believe I tried ext 2 as well. Without 2nd partition obb and data stay on internal. Thanks

I wish to thank the OP for this, as I am trying to use, and bought the recommended apps... haven;t had the time to set this all up, and it gets a little confusing having all these other devices, but eventually I'll get it.
