Solution
Well that 16GB is the total storage. Not the amount you have access to. You have to remember that even when you first get the phone, much of that space it already taken up by the OS and all the preinstalled apps. Then every app you add, contacts you input, picture you take, file you download, update you install, takes up even more of that space. On top of that you have your browser history and cache, text messages (if you don't delete them), and the info in every app you access and use regularly.

Now you can try either moving files that you have on the phone (files, not apps) to a SD card, if you have one installed, or you can 'try' to convert the card over to "Internal" storage rather than the normal "External" storage, so that you...

On top of that you have your browser history and cache, text messages (if you don't delete them), and the info in every app you access and use regularly.

Now you can try either moving files that you have on the phone (files, not apps) to a SD card, if you have one installed, or you can 'try' to convert the card over to "Internal" storage rather than the normal "External" storage, so that you can run apps from the card. I am including instructions for both below. Then you can choose which to try.

If you want to just move files (photos, videos, music, etc.), not apps, to the SD card you can use the file manager app that is on the device, or if there isn't one you can download and install one to access and move the files. Sadly, they usually only let you move one or two at a time.

To move them all at once, or in large amounts, you can connect the phone to a computer via USB cord, then move the files over to an empty folder on the computer. Once there, and still connected via USB, you can then move or copy the files over to the SD card. Personally I would suggest leaving a copy on the computer as a back up.

Once that is done you should then go into the apps that you access the files through (like gallery, etc.) and change the apps individual settings to look for the files on the SD card. You may also want to change the settings in apps that you use to create new files (like the camera) to save new ones to the card rather than the phone.

Now if you are wanting to move apps to the card, that is a whole other story.


First, you need to be using a phone that is running at least Android "Marshmallow" (6.0) or newer, or be able to upgrade to it. Second, you will need the instructions I am including below. And third, you need a phone that has not been restricted by the manufacturer from making this change. Which does happen.


NOTE: If any of the steps are missing on your phone, or they don't work for you, then you have a phone that either has an older Android version or has been restricted by the manufacturer. If that is the case, you will not be able to use this information.


How to turn the "External" SD card into "Internal" storage - Option A

NOTE: Please be sure you start with a blank SD card. It needs to be blank because when the card is converted to "Internal" storage, it will be formatted (wiped) and encoded (making the cards data only readable by that device).

1. Go to device “Settings”, then select “Storage”.
2. Select your "SD Card", then tap the “three-dot menu“ (top-right), now select “Settings” from in there.
3. Now select “Format as internal”, and then “Erase & Format”.
4. Your SD Card will now be formatted as internal storage.
5. Reboot your phone.

NOTE: If you don't reboot the phone, many things may not work correctly, so make sure you do.


How to turn the "External" SD card into "Internal" storage - Option B

IMPORTANT NOTE: Be sure you start with a blank SD card. When the card is converted to "Internal" storage, it will be formatted (wiped) and encoded (making the cards data only readable by that device), so anything on it prior would be gone.

1. Go to "Settings", and then select "Storage & USB".
2. At the bottom of the list you should see the SD card's details, including the option to format it and make it "Internal" storage.
3. Once this is done, reboot the device and you can start running things from the card.

NOTE: If you don't reboot the phone, some things may not work correctly, so make sure you do the reboot.


A Final Note: If you set up the card as "Internal" storage, then the data on it will not be readable by any other device. To access the data you would have to connect he phone to say a computer and copy it over to the computer from the phone/card. Otherwise only phone can read the data. Also, be sure you do not reset (hard or factory) the phone. If you do, then all the data on the card will no longer be readable, even by the phone itself.
