Google is heavily rumored to be holding a launch event on Sept. 29 at San Francisco to uncover the next generation Nexus 2015 smartphones. As previous rumors have revealed, the LG Nexus 5 (2015) and the Huawei Nexus 6 (2015) flagships are slated to get announced at the end of September.

According to CNET, the Sept. 29 launch event will unveil the two Nexus 2015 flagships with Android 6.0 Marshmallow operating system onboard. However, there is no confirmation on the launch event from Google.

The LG Nexus 5 (2015) will be the third Nexus smartphone from LG after the Nexus 4 from 2012 and the Nexus 5 from 2013. For the first time, Google has partnered with a Chinese vendor, Huawei for building the purported Nexus 6 (2015).

CNET said that the Google-Huawei partnership is very vital for the Chinese smartphone maker because even though it has manufactured several affordable high-end smartphones, it is yet to become popular in western markets like the U.S.

Phone Arena’s report from July claimed that Google services like the Google Play are not available in China while users in the country rely on third-party app stores like the Qihoo 360, Baidu and others. Hence, Google-Huawei partnership may help the search engine in building its own official Android app store for Chinese audience.

Both LG and Huawei Nexus smartphones are expected to feature dual frontal speakers, USB Type-C connector and fingerprint sensor. The LG Nexus 5 (2015) will be a smaller device that will feature 5.2-inch full HD display, Snapdragon 808 chip, 3 GB of RAM, a 13-megapixel OIS enabled camera and a 2,700 mAh battery.

The Huawei Nexus 6 (2015) will arrive with 5.7-inch Quad HD screen, Snapdragon 810 chip, 3 GB of RAM and 3,500 mAh battery. The LG Nexus 5 (2015) is expected to be priced around $350-$450. On the other hand, the Huawei Nexus 6 (2015) may cost around $450 to $550.
