The Google Pixel 2 series devices which are highly anticipated to arrive in October might feature a rear trackpad. According to a patent filing on Tuesday, the device is reported to feature a touchpad where most mobile phones have a brand logo at the back.

The search giant company was granted the patent by the U.S. Patent and Trademark Office last week. "It would be advantageous to have an improved touch sensitive surface that offers additional modes of operation," Google said in its filing. Also, the same control pad is expected to read and interpret user gestures, suggesting a unique Pixel phone functionality that the report said will not be found on other flagship models, and that includes the iPhone 8.

The Google patent discussed the usage of "a resistive touch sensor, a surface acoustic wave touch sensor, a surface capacitance sensor, mutual capacitance sensor, a projected capacitance sensor, an infrared grid sensor, an infrared acrylic projection sensor, a self-capacitance sensor, an optical imaging sensor, a dispersive signal sensor, an acoustic pulse recognition sensor, and so forth," reported by BGR.

The upcoming Google Pixel 2 series will feature an edge-to-edge display with a 1440 x 2560p display resolution, dual cameras at the back and will most likely come with Android O.  Snapdragon 835 will possible power the upcoming Pixel 2 series, backed up by at least 4GB of RAM and with better water resistance standard from the IP58 to IP68. As Google launches its phones towards the end of the year, it will be possible that the company will launch a new device until around October 2017.
