other storage

Hello and welcome to Apple Support Communities, edithglz!

We understand you want to know about other storage. We'd be happy to provide information about this.

More information can be found here: How to check the storage on your iPhone, iPad, and iPod touch

"Content categories 

The used content on your device is divided in these categories:

• Apps: Installed apps and their content, and content stored in "On My iPhone/iPad/iPod touch" directory in the Files app, and Safari downloads 
• Photos: Photos and videos stored in the Photos app
• Media: Music, videos, podcasts, ringtones, artwork, and Voice Memos
• Mail: Emails and their attachments
• Apple Books: Books and PDFs in the Books app
• Messages: Messages and their attachments
• iCloud Drive: iCloud Drive content that has been downloaded locally to your device. This content can't be automatically deleted.
• Other: Non-removable mobile assets, like Siri voices, fonts, dictionaries, non-removable logs and caches, Spotlight index, and system data, such as Keychain and CloudKit Database. Cached files can't be deleted by the system.
• System: Space taken by the operating system. This can vary based on your device and model."

Have a great day!

The issue is that the "Other" category keeps growing in size as other items are deleted off of the phone so no matter what, the phone keeps having the error that the storage is full. My "Other" category has grown to over 20 GBs now and that's after I deleted about 15 GBs worth of photos and messages. Now I can't sync or backup my phone on my CPU because it says there's not enough storage space. My phone is essentially useless since apps continue to crash. This needs to be fixed ASAP. This is an issue on Apple's end.
