Unfortunately, smartphones don't have internal expandable storage. You might be able to get an app of the play store that allows you to move more apps from your phone to the card. Make sure to you have your photos and music saved to your SD too. You should also use [https//:photos.google.com|Google Photos] to make a cloud backup of your photos online. This way, you can remove the photos from the phone and have backup in the sky. Hope this helps.
