When google strated their Nexus series I was most impressed with their nexus 5 among the all previous versions they launched. I can fan of nexus 5 for to following
1. Elegant and classy design. One of the best looking phones
2. Excellent display 445 ppi and full hd screen.
3. Build quality is great with light weight just 130gm
4. Buttery smooth performance due to stock Android. Google optimizes software as they own it respective to the hardware.
5. Recent updates of current version of Android due to nexus series.
6. Classic camera.
Thanks LG for making nexus 5.
