Why does my phone say my photos are like 9Gb out of my phone yet I've deleted thousands of it and I still have no memory left?
You've got some different questions here. The iCloud app isn't meant to show your photos; that's what the Photos app is for. When you delete photos, it doesn't actually delete them; it puts them in a folder called "Recently Deleted" where they are retained for 30 days before actually being deleted. You have to delete them again from that folder if you want to delete them before the 30 days are up.

To see what's using space on your phone, go into Settings / General / Storage &amp; iCloud Usage / Manage Storage (the first one, under "STORAGE" not under "ICLOUD").
