... a dead pixel (possibly dust, but probably pixel.) Upon finding it I was irritated by it, and then it became a bit of a niggle. Learned to live with it, ish, then a friend reminded me it's a £700 device and it shouldn't have anything wrong with it, which is also true. Reluctant to do anything in case an exchanged model has one or more dead pixels and this phone is otherwise perfect. So, just curious; would you swap it for the sake of one dead pixel?
