The First Smartphone To Run Android OS 7.0 Nougat is LG V20

LG V20 will be the first smartphone to come with Android 7.0 Nougat operating system (OS).

This LG V20 will be officially launched on September 6 which is the same date that HTC is launching the their Nexus devices.

According to google spokesperson said:

LG V20 is gonna be the direct rival to latest Samsung flagship device, the Note 7 but the V20 will definitely prove superior in one aspect and that is the software. While it is coming with Android 7 straight from the box, it will take the Galaxy S7 about two to three months before the Nougat updates starts rolling out.
