Two ways to choose to use micro SD card as portable storage in Android Marshmallow?

You have two different ways to choose to use micro SD card as portable storage in Android Marshmallow:

  • when you first install the micro SD card.
  • you can convert a micro SD card from internal storage to portable storage.

The results are identical.

How to convert micro SD card from internal storage to portable storage?

If you set the micro SD card as internal storage, you can always convert it to portable storage at any time.

To convert SD card from internal storage t0 portable storage, you need first go to Settings.

Tap Storage & USB.

In Storage & USB page, you can find SD card is combined with phone storage as ‘Device  storage’ as shown below.

But SD card usage is also reported separately as shown below. Please note, when SD card is used as internal storage, you should let the system to decide how to save files.

Tap SanDisk  SD card (I am using SanDisk in the guide) as shown below.

Tap menu key (3 vertical dots near top right) as shown below.

Among the menu items, as shown above, you can find:

  • Rename
  • Eject
  • Format as portable

Tap format as portable.

Now you are prompted to format the SD card. Tap Erase& Format as shown above to format the SD card and convert it to portable storage.

When you  formatting the SD card as portable storage, all files on the SD card will be erased. This means some apps may not work properly after you convert the SD card from internal storage to portable storage.  For these apps, you may have to re-install them.

My computer can recognize my phone after Android Marshmallow update, but does not show any contents of internal storage and portable storage (SD card).

If the phone is recognized, but phone (internal) storage and portable storage are all shown as empty, you need check the notifications on the phone.

In Android Marshmallow, by default, the USB option is charging only. You need set USB option to MTP to see all contents on the phone storage and portable storage.

You can change the USB option from the notification panel on your phone.

My computer shows phone storage contents,  but does not show any contents in SD card under the phone,  although I already chose to use micro SD card as portable storage.

If you can use the SD card as portable storage on the phone, and the computer can show contents in the phone storage, but not SD card, you may have to format the SD card once.

Actually, if 1). your phone is updated to Android Marshmallow  (not pre-installed with Android Marshmallow) and 2). the SD card was installed and used before the update, you should format the SD card once after updating to Android Marshmallow.

This is a known problem for most Android phones. The Android Marshmallow update from most Android manufactures failed to propagate some SD card features.

You just need format the micro SD card once after updating to Android Marshmallow. Using a new micro SD card after the update is NOT affected.

Do you know how to use micro SD card as portable storage in Android Marshmallow device now? Can you convert micro SD card from internal storage to portable storage in Android Marshmallow device?

    I chose portable storage for my sd card in Android Marshmallow. Does this mean all photos and music automatically go to the sd card or do I have to manually move them to a certain folder on the sd card? If I have to manually move them, how do I do this?

    Hello guys and thank you for your post on this regard.
    I have a question: I didn’t know about this new feature and used 16gb SD class 10 card. No problem with that.
    The thing is that now I’d like to upgrade to a 32gb faster card.
    HOW can I do that? at this moment my 16gb card has many apps and data. How to transfer my data to the new card. Is it possible?
    Many thanks in advance for your help.
    Cheers!

    I have several SD cards with pdfs and other documents I use for reference and I swap these out depending on what I need. My Galaxy S7 Edge keeps creating an Android folder on my cards even though I have all apps and camera set to Internal Storage.

    Is there a way to stop the OS from creating folders on my SD cards?

    I have a Samsung tab SM-T800 which has recently updated to Android 6.0.1. I cannot now find how to move or choose to put apps or data on my SD card which used to be easy with Lollipop, using the Apps Manager. So I have data on my SD card but the app cannot read it because it is permanently set to use internal storage – the storage option on the app is greyed out and set to internal. Is there anything I can do? I have masses of space on my card but it appears that I can’t use it. And some apps can’t access data which cannot be read by anything else.

    I read above that Samsung removed the facility for internal storage use of the SD card. Is there any way around this? I am hugely disappointed with my J5 – 8GB gets nowhere these days – and would like to use the Adoptable storage route. Can you point me in the right direction or is it just impossible?

    Greetings,

    I’m using SD Card as Portable, but having problems detecting it as a storage especially for WhatsApp, how do I get WhatsApp to work on the Portable SD Card on Android Marhsmellow 6.0? I don’t want to adopt it.

    I was considering to root it then use link2SD but I’m not sure yet, please advice me on how to enable this without using adoptable SD card.
