also i would recommend that you make sure that you use google photos as well. if you set it, it will always update your photos to the cloud when you are connected to wifi. this way you have your photos saved somewhere other than your phone. if your phone were to get stolen or break, you can always log into google photos on any device like a computer and be able to get access to your most current photos.
you can't really organize it a certain way, but it is setup by date. you can create albums to group your photos and have it organized that way.
i just like the fact that i never have to worry about my photos again. it is always backed and very easy to either download or view.
