These phones are only cheap because the consumer market is giving them away (high supply). That makes them very good for specific applications and given the presense of complex sensors, battery backup, and small form factor you have a very attractive package for potentially important use cases. That's also just setting asside the idea that someone might want to use these pieces. Some third world countries may benifit from a huge influx of cheap technology every year.
Then compare iPhone 5S (£120) [1] vs Samsung Galaxy S5 (£130 - 140) [2].
I really don't understand why. Perhaps there's just more people that want to buy second hand android phones.

The Galaxy S5 was released half a year after the iPhone 5S, which might explain the price difference.
Pity. My SE feels cheap and light by comparison, and its materials don't hold up nearly as well. I don't like that, but given the strictly limited lifespan that smartphones seem to have, I suppose it's really quite apropos.
Probably because the iPhones are specced just enough to last a couple of years, whereas Android phones are over-specced as hell, even the Galaxy S4 had 4 cores and 2GB of RAM, which is still more than useable today...
