As a Galaxy s22 user I find the backup option useless, because it does not include the albums or subfolders in the camera folder. Also, it backups deleted photos in the recycle bin. Imagine you took a hundred photos on a trip an decided to keep a few of them. ALL deleted photos will be backed up and appear in the google photos and you will have to review them again and manually delete those you want to remove from the backup. Useless.
