Here is my genuine review after using it for 1 month of use.
design quality of this phone is very good, has an aluminium metal uni-body design having fingerprint scanner on back.
display quality is very good as it has amoled display but it is not as good as samsung galaxy s6 and note 5.
camera quality of this device is awesome in daylight as well as in artificial lightning. it is not as good as note 5 but it is better as compared to galaxy s6.
battery life of this phone is not that great. if you are a heavy user, then you will have to carry a power bank while travelling.
performance of this phone is awesome, certainly the best in the market.
fingerprint is very accurate and best in the business.
sound and call quality of this phone is awesome, volume level is great too.
users will get all the latest updates regularly as it is a nexus device. I will suggest all the users to definitely buy this phone, it is the best phone of year 2015.
