“All phones and tablets come with a preset amount of storage that ranges from 16 giga-bytes to more than 256 gigabytes,” says Harris. ”The more apps, photos, and videos on your device, the more storage it uses.” If you exceed your device’s storage capacity (plus the capacity of any free cloud-based storage, like the five gigabytes of storage Apple users get on iCloud), this is the message that you’ll see when you try to take a photo or a video, or download an app, music, or files. Fix it by clicking on Settings to delete any large unused app, photo, and video files. If you’re seeing this message regularly, consider increasing your cloud storage with a service like iCloud or Dropbox. Prices range from $1 a month for 50 gigabytes to $20 for two terabytes.
