How to move internal storage to sd card galaxy s9

I have tried every way to switch my SD card to internal storage. Please help me, I am very confused

I will be honest with you and say that Samsung tends to not allow their devices to be changed so that the SD card can be used as internal storage. However, I will include the instructions on how below. Just in case you want to try.

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.

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.

5. Reboot your phone.

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

IMPORTANT NOTE:

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.

An Additional Note: Some apps (like system ones) are not movable. So while you can move downloaded ones, and some of the system ones, you will not be able to move many preinstalled apps.

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.
