Google, the internet search giant as well as the company which is responsible for maintaining Android has just announced the Google Pixel 2 and Pixel 2 XL smartphones earlier this year. Now, these smartphones are the successors to the Google Pixel and Pixel XL smartphones that were launched by the company around the same time last year. Also, the Google Pixel and Pixel XL became the first smartphone to be manufactured and designed by Google itself as the company released the Nexus smartphones in the previous years which were the flagship Android smartphones from Google that were developed in partnership with Android OEMs.
