Microsoft Lumia 640 (since July 2015), I get made fun of for having a Windows Phone but I'm not that bothered. I like the user friendliness of it (live tiles, having a dark screen, the way that contacts are stored as people cards) and it was cheap on PAYG. The apps side of things aren't great, the Android/iOS versions of apps like Instagram and Facebook are much better and the widely documented 'app gap' but I have the apps I need so it's not as much of an issue.
