Google's Pixel 2 Android smartphones are highly anticipated to roll out in October with a rear trackpad feature. A patent filing made it known that the Google Pixel 2 series will feature a touchpad where most handsets have a brand logo.

The U.S. Patent and Trademark Office granted the search engine giant last week a patent. Google made it known that it would be fortunate to have an improved touch sensitive surface that comes along with additional modes of operation.

Also, the feature is expected to interpret and read user gestures, which suggest a unique functionality of the next-gen Pixel phones that will not be found on other flagship mobile devices, and that includes Apple's iPhone 8. Google's patent discussed the use of a surface acoustic wave touch sensor, a projected capacitance sensor, a resistive touch sensor, an infrared grid sensor, an optical imaging sensor, acrylic projection sensor, among others, BGR reported.

Meanwhile, the Google Pixel 2, which is dubbed as Walleye, will arrive with a 4.97-inch full-HD display. The Google Pixel 2 is expected to remove the 3.5mm headphone jack. Although the tech company hasn't officially confirmed the report yet, the upcoming mobile device is expected to be available with a single-lens camera on the rear panel, Blasting News reported.

The upcoming Google Pixel 2 will most likely arrive with Android O, Qualcomm's Snapdragon 835, at least 4GB of RAM as well as better water resistance standard from IP58 to IP68. The price of the upcoming Pixel 2 and the Pixel 2 XL smartphones remain unknown. The release date of the devices is widely expected to be slated sometime in October.

The Google Pixel 2 series will be among the many exciting Android smartphones set to roll out in the coming months. The best upcoming Android handsets include LG G6, LG X Power 2, Galaxy Note 8, Nokia 9, Asus Zenfone AR, HTC U11, iPhone 8 and Xiaomi Mi 6.
