Likely fix
Fix: System Data or Other storage is huge
System Data or Other storage can grow because of caches, logs, temporary files, failed updates, streaming app data, browser data, and message attachments.
Quick answer
Restart the phone, update the system, clear browser/app caches, delete large app downloads, and free normal storage first.
Important warning
System Data is not meant to be manually deleted file by file. Focus on apps, caches, downloads, and backups first.
Try this
- 1 Restart the phone.
- 2 Install pending system updates if you have enough space.
- 3 Delete large videos, downloads, and unused apps first.
- 4 Clear browser cache.
