Can i restore my iPhone videos after factory restet on iPhone?

My iPhone was factory reset by a shop around a year ago. Since then i have restored what i can through iTunes and icloud but there are still things missing. I had a video on an external app in the phone saved but after the reset it had disappeared for good. Could the original video still be on the phone considering its been a year since it happened? If so, how can i retrieve it? I have tried all the conventional methods in terms of external apps that find deleted content, they don't find what i'm looking for, can we go deeper in the phones past and recover the video?

My iPhone won't backup and is saying I have no iCloud storage when I should

My phone has been saying for a while, I have no iCloud storage and it hasn't backed up since May 2017. I'm switching my iPhone from an iPhone 5s to an iPhone 6. So I tried to sort out my iCloud storage. It turns out I was using a lot of storage on my photos, so I downloaded them onto my laptop. I kept around 100 of the very many 3000 photos! For a keepsake as I like having it there and now I'm using 542mb of storage for my camera roll. I now have 4.7gb available as I have used storage for other things. But on my iCloud storage it says I'm using up 4.06gb on my camera roll when I'm clearly not. And I want to get it to back up but I don't know how. I only have 5gb of iCloud storage and I'm not prepared to pay for extra, does anyone know what's going on and how I can solve it? My phone has been updated and it is on iOS 10.3.3

IPhone 5c randomly restarts?

So, I recently got an IPhone 5c, and it randomly restarts at least once a day. I'll be doing something normal like scrolling through twitter or listening to spotify and it'll just go to the apple logo, flash a few times then maybe 2 minutes later it comes back on, but if I do anything to quickly it restarts again.

Does anyone know how I can fix this?
