This is one of the best phones I have ever used in my life. Instead of buying an iphone I went for Nexus. This phone is just amazing. Have been using it for 2 and a half years now. No problem at all. There is one problem with this phone that is its camera. Now the market has good quality cameras in phones with medium price range. Rest all this phone has is perfect. The size of this phone is perfect. the User Experience is the best one can ever have. The best of all at the time it was launched. I have also used Nexus 6, but the satisfaction that you get after using a phone is given by this beautifully made Nexus 5. Kudos to this product!
