Photo stream vs Camera roll on my iPhone?

I know the difference between the photo stream and camera roll on an iphone, but the only Apple device I have is my phone itself. Can I just delete all the pictures in my photo stream since they are already on my camera roll? I feel like they take up a lot of storage I could be using for other pictures, music, etc.

You don't know the difference between photo stream and camera roll.
photo stream isn't on your phone storage its your icloud
camera roll is your phone storage

Yes.

  • When you delete photos from your Photo Stream does it delete from your Camera Roll? Hi, I'm running out of storage on my phone so I thought the best thing to do would be to delete some photos, and obviously my photo stream folder uses up tons of space, but when I delete photos from the photo stream do they delete from camera roll too? Or vice versa? Obviously I'm using Apple (iPhone 5C) please answer quickly and thanks x

  • Taking photos on iPhone to appear on another iPhone's photo stream? I'm going on holiday and don't want to take my iPhone 5c as it might get damaged/lost etc. So I want to take my old iPhone 4 just to take pictures on it. I was just wondering if there was anyway so when I take a photo is automatically appears on my iPhone 5c's photo stream back home? (This is just incase I lost my old photo - which wouldn't matter too much since it is extremely slow)
