Re: a £200 phone that does everything an iphone does.
iPhones don't degrade like Androids do. I hope you've found a good one but I've found that even if you don't install any software they degrade over time. When I got my 8 core £200 Android the bluetooth audio was perfect. 6 months later and there was the occasional stutter. A year later it will stutter at least once every 30 minutes.
Try doing that with an iPhone.
