In September time last year I had a Lumia 920, and while I really really liked the build and quality of the phone itself AND the windows GUI layout I ended up really struggling with the lack of official apps. Facebook was a pain as I was getting no notifications along with the likes of twitter and also Instagram. I was coming from an Android background and with everything tied into Google, the likes of no official gmail or google maps etc was also a bit of a struggle. The whole notification side of things I found to be pretty dire. It could just have been me, I don't know? Subsequently, I ended up selling the phone and I'm now running an iPhone 5S. Although, I still really like the look of the 1020 and 1520 as the handsets are really well built. Has the Windows Phone OS got any better with notifications, official app support etc?
