Google would want to push out the Nexus 7 2 ahead of the purported iPad Mini 2 with Retina release date this year.

In doing so, the tech giant is reportedly changing its production partner for the 7-inch tablet, shifting from first Nexus 7 maker Asus to another Taiwanese firm Quanta. The jump, according to market research firm IHS, will allow Google to advance the market entry of its iPad Mini killer.

The Nexus 7 2, according to CNET, is now geared for a July release date with a display resolution of 1920 x 1200, coming from the first Nexus 7's 1280 x 800 screen prowess.

Two possible partners in producing the second-generation Nexus small tablet are Japan Display and AU Optronics, which last week was reported to have been excluded in the production of the Retina-laced iPad Mini 2 due to poor production performance.

Together, the two will conspire to deliver a Nexus 7 2 with a pixel density of 323ppi, the report said, enough to challenge the rumoured main come-on of the iPad Mini 2, which is a screen resolution of 2048 x 1536.

Earlier, Taiwanese publication DigiTimes has reported that a 16GB Nexus 7 2 is hitting the global market come July with an affordable price tag of $US229, supporting the latest development about the Google-centric tablet.

It was followed by the appearance of the same Nexus on the U.S. FCC that details the slate's supposed specs of a quad-core Snapdragon CPU, a massive 4000mAh battery, a decent mix of rear and front and better connectivity from the first make.

Of notable addition is the LTE chip that ensures constant and fast internet access for the Nexus 7 2.

If it turned out that Google Play Store will start taking orders of the Nexus 7 2 in July, it will enjoy a headstart of at least three months from the iPad Mini 2, which Apple will likely release between October and September this year.
