I have been using a nexus 5 for 2 years now. Its design is great . it is light weight . it sports the latest android version , a 8mp rear cam and a 1.8 mp front cam and ofcourse a 2GB RAM. After 2years this phone still works like a dream .
Very smooth though it lags sometimes but that is not a big issue . If you are a selfie freak I woudnt recommend you this phone though the pics are great but only in suffivient light. One big problem of this phone is the battery life. An average 2300Mhz battery doesnt long the whole day. The battery gets you an average of 2-3hrs screen display time. If you are regularly checking up the social media or playing games then this is not the phone for you.Overall I would say if you are not an extensive user of your mobile phone but want to have almost everything in your hand then it is the phone for you .
