Six months after its global debut, LG Nexus 4 smartphone Nexus 4 was released in India last week. Around the same time, Japanese electronics major Panasonic also forayed into India's lucrative smartphone business with the launch of Panasonic P51.

Both Nexus 4 and Panasonic P51 pack quad-core processors, impressive feature-rich cameras and run on the latest Android mobile OS v4.2 Jelly Bean. But since Nexus 4 is co-developed by LG and Google, it has the advatage of being the first smartphone to receive any new OS update. Even though it was launched in November last year, Nexus 4 still maintains a cult brand following globally, while Panasonic's P51 is just a week old in the smartphone arena. This aspect may play a role in the minds of prospective buyers.
