Step 1: Select Set Up. Step 2: A new screen displays. There, you select what you want to do with your SD card. You have the option of using it as portable storage or Using it as internal storage. Select one and press on Next. Step 3: If you use it as internal storage, you will be taken to a new screen where you can format the Card. Press on Erase and Format if you don’t have important files or already have backed up what you need. Step 4: The system will take you to a new screen where it will say you need to move the apps in your SD card to Internal Storage if you want to avoid losing them. You can either ‘See Apps’ and then move them to your Internal Storage, or select ‘Erase Anyway‘ to move forward with the process.
