Android devices come with a variety of storage options, including internal storage and a SD card. Internal storage is the default storage on Android, but you can change it to be the default storage on your device by going to Settings and selecting Storage. From there, you can choose to have your device use the SD card as the default storage or keep it as internal storage. If you choose to have your device use the SD card as the default storage, you will need to make sure that your SD card is formatted in FAT32 format.
