The Pixel runs the latest Nougat 7.1 with the new Pixel UI on a Snapdragon 821 chipset, also the latest, with 2.15 GHz quad-core processor
and 4GB of LPDDR4 RAM
and 128GB of storage with no option to expand. The RAM and CPU will handle demanding apps as well as multitask with ease. The phone comes with an auto-cleanup feature that clears space when the limit is reached. Google also provides unlimited space via the Google Photos app for life at maximum resolution with the phone. Apps such as Allo and Duo come preloaded with the phone, and Google Assistant, that is touted to be better than Siri, all of which face major improvements with the latest OS.
