Lg nexus 5 is a good phone but its price is too high. The feature it provided like 2 gb ram and 16/32 gb inrernal is also is in the phone which price is near about 10000.But price of this phone is 23, 538 which is too high for this type of features.
Secondly it has android kitkat which is an older version of android whereas other phone provide latest android lolipop.I want to say that you only buy this phone if you like it.
