What phone(s) would you recommend at under £200? New or used.
You won't get anything for under £200 that's better than the LG G5, despite what I said I would still recommend it, the performance and camera are very good.
Maybe do some due diligence on the seller before you hit the buy button though, good feedback and good return policy.
What about the Xiaomi Mi5? That can be found for around that price, just have to get it shipped from Hong Kong.
Currently using an LG G5 the camera is decent battery life was good to start off with but has got a lot worse over recent months(considering picking up a new battery)
Main problem though is screen burn in both phones i have had after sending the first one back has had this problem but i have fixed it using bluelight filter.
How are you getting burn in? they're both using IPS displays.
A lot of people have the same problem, i had to removed the notification bar as it was constantly burning into the screen, i use whatsapp a lot and after been on it for a while i can still see the outlines of my conversations when browsing the web unless i leave my screen off for a while.
So I ended up going with the G5 (here is the listing btw) as Shocky pointed above there really is nothing else comparable at that price point, well I suppose the Xiaomi Mi5 does but the cheapest option was having it shipped from HK with free (no tracking) delivery and despite a few people reporting not paying duty, I just really didn't want to risk it and having to wait an eternity in the process. They're 'seller refurbished' not sure what context, simply faulty (and repaired) returns? It would be my first 'used' smartphone purchase so we'll see what my experience is and if encounter any of the issues that plagues the G5 then it's a simple return... hopefully.
