Why do my pictures take up so much storage?

I have a black iPhone 5s and it's capacity is 12.1 gigabytes. I also have bought 200 gigabytes for iCloud storage. I've had my iPhone 5s for almost a year now, and my storage has been acting up lately. I've deleted most of my pictures and I now only have 35 pictures and 2 videos. The weird part- it says that my photo library takes up 10.2 gigabytes! I can't download and other apps and the only other apps that I have are Clash of Clans, PlayBuzz and Wishbone. I have no songs.

How to stop a iCloud restoration on my iPhone?

My previous 5s broke and my mom got me a new one, but I'm at work right now so she had to go get it and for some reason they made it required for someone to sign into an Apple ID before she left the store. She brought it to my work and now I'm stuck with all **** because of iCloud. I tried to delete it but it won't let me because it's still being restored as I'm not in Wi-Fi atm.

IPhone 5 already have stored hidden files?

IPhone 5 already have stored hidden files?

Added (1). So i just got a 'new' iPhone 5c from work, i know its not brand new because it has been updated to 8.3, so maybe its second hand but it is in good condition and other than the 8.3 update it is in factory settings. Although i looked at the size of the phone noticed it was 5.4gb, which is typical as the system files take up about 2gb but then it says it has 400mb of storage used, however there are no apps, no musics, pictures etc, so what could be using the storage? Hidden files? To tap calls?
