If you're getting a file system limit error on your phone, it means that your phone's storage is full and it can't save any more files. This can happen if you have too many apps installed, or if you have a lot of photos, videos, or other files stored on your phone.
To fix this, you'll need to free up some space on your phone. You can do this by uninstalling unnecessary apps, deleting old photos and videos, or moving files to a cloud storage service like Google Drive or Dropbox. If you still can't free up enough space, you may need to buy a new microSD card for your phone (if it has one) or get a new phone with more storage.
