Google phones are the best! And Nexus 5 is no different. A phone which got all the updates right from KitKat to marshmallow, Nexus 5 is worth every single penny.
Performance is buttery smooth, thanks to its 2GB RAM and 2.26GHz processor. I've been using this phone from the time it was launched and to be honest, it does not feel like it is a 2 year old device! I've never noticed any lag on this phone. I would rate this phone a 10 out of 10 and would still recommend people to buy it!
