    I'm glad you raised this question, because I generally find no apps or .apks on external storage.

    I'd also like some clarification on the various storage options:

    • ext SD (microSD),
    • "emulated",
    • "SD",
    • "0", and then
    • "internal" w/sys and system.
    There's a fair amount of redundancy, however even though the folders and directories look comparable, there are differences in content. I also have found it impossible to find Apex and other apps and/or their components (themes, wallpapers, etc.).

    Never had this confusion on my HTCs.. Anxious to see the responses here!

    I'm really surprised no one has chimed in on this yet. Yes, to answer your question. Go into your setting and applications manager and go to the "On SD Card" tab. from there you can check which apps you want to remove from internal storage to your SD card.

    No sure about anyone else's S4, but my S4 (GT-i9505G) does not have that tab.

    The question is though, whether that really does what it says. Per the person in the other thread I linked it does not. Thinking about it today I don't see how that could be true, but I would like an answer.

    I Googled around about this and found an article on "How To Transfer Apps To Micro SD Card On Updated Handsets"....

    It said, "The Samsung Galaxy S4 has received a system update on the AT&T, Sprint and Verizon networks that primarily allows users to install and transfer apps from their internal storage to a micro SD card. This function is usually disabled on devices powered by the Android operating system because Google discovered that micro SD transfer often causes certain apps to malfunction."

    What network are you using?

    I'm on Verizon and my phone has the feature to transfer the apps to MicroSD.

    Here's the posts I linked, but apparently need to copy to here so that people will know what I'm asking.

    Now maybe I'm misreading all of that, and the phones that cannot transfer are like Retrah's and don't have the tab to do the transfer. But they do seem to be claiming that at one time the transfer feature was there, but didn't really transfer anything to microSD.

    So then the issue you're having is that the apps don't really get moved to your SD card?

    That's what I'm trying to determine. That first quote suggests that they aren't, but I have a hard time believing that's true. The article you posted (thanks!) says they do actually get moved, and when you look at the place in Application Manager where you actually move them it reports the space available on the card, so I find it hard to believe that they wouldn't be moved. But I'm just trying to follow up on that post.

    Can you take the SD card out and put it in something else to see if they are really on there? I mean, if you have something else with a card reader, that is.

    Goodspike; I have no idea if this applies, but thought I would quote the post anyways just in case something was helpful. Someone asked about moving large apps to the external SD in another thread elsewhere.

    Yes and no. The entire app does not get moved to the sd card.
    The data and other "files" get moved into the .android_secure folder as a single .asec file while the actual executable .apk stays on the phone.

    I still haven't tried removing my card and viewing it on a PC, but isn't what you describe what Android did back in the Gingerbread days? That's basically what my question is--did Samsung get Android to do what it used to do?

    Goodspike - Lunatic59's explaination is pretty much spot on. It will move a LOT of the information to the SD card but a portion of the app will still have to be stored in your internal memory.

    I read about how apps to sd worked some time ago (probably during the GB era) but in my ignorance didn't know that the apps to sd method had been changed for the S4 so I did a quick test.

    I determined how it is done on my S4 by formatting a 4gb card, checking for files (there weren't any files only two empty folders; .android_secure and LOST.DIR) and then moving several apps from phone storage to sd and then checking again. In each case an asec file was created in the .android_secure folder for each app that was moved to sd and the apps would not work if the card was removed. When I moved the apps back to phone storage, the asec files were gone from the sd card and the apps worked without the card installed. It may not be the most scientific way to verify the process but it seems to be the correct answer :thinking:
