If your Huawei photo album suddenly becomes larger, it may be because your phone automatically backs up photos to the cloud, or your phone downloads photos or videos shared by others.

Here are some possible reasons and solutions for the increase in photo album size:

1. Automatic backup: If you turn on the Huawei cloud backup function, your phone will automatically back up photos to the cloud. You can select the "Cloud Album" tab in the "Album" application to view your cloud backup photos. If you do not want to back up photos, you can select the "Cloud Service" option in the "Settings" application and turn off the backup function.

2. Shared photos or videos: If your phone downloads photos or videos shared by others, it may cause the photo album to become larger. You can select the "Recently Added" tab in the "Album" application to view recently added photos or videos. If you do not want to download shared photos or videos, you can select the "Album" option in the "Settings" application and turn off the sharing function.

3. Application cache: Some applications may cache photos or videos on your phone, causing the photo album to become larger. You can select the "Application" option in the "Settings" application, then select the application you want to clear the cache, and clear the cache.

4. Duplicate photos: If you have duplicate photos in your album, it may cause the album to become larger. You can select the "Duplicate" tab in the "Album" application to view the duplicate photos, and then delete the duplicate photos.

It should be noted that if you delete photos or videos, they will also be deleted from the cloud backup. If you want to keep the backed up photos or videos, you can move them to other folders instead of deleting them.
