The Google Pixel 8 and 8 Pro will offer a remarkable seven years of software support, meaning users can expect to use them until 2030 without their software becoming outdated. This is a significant improvement compared to previous offerings from Google, which provided only five years of security updates and three years of Android OS upgrades. This extended support period surpasses what most of Google’s Android competitors are offering, giving Google a unique advantage. The use of its own Tensor processor in the Pixel 8 series allows Google to have more control over the hardware and provide longer support. However, Fairphone still outshines Google by promising eight years of security updates with its Fairphone 5.
