My phone started to become really slow, and then I tried updating it. It wouldn't update so I deleted my apps and the update didn't work so I just tried to re-download my apps, which wouldn't work. I think I might have logged out of the iCloud but now every time it asks for my password I type it in and then it comes up again constantly. This then means I can't download apps which is my biggest problem. I also don't have any photos because they disappeared and my apps keep shutting down. I'm not sure if any of these are related.
Please please help.
Thank you.
