This year's Google Pixel 4 released with a mix of interesting and downright useless features. The 'smooth' 90Hz display was a welcome addition (and would have been better if it actually worked as intended) along with a much-needed bump in RAM. Project Soli-based Motion Sense is a gimmick at best, and it is responsible for the Pixel 4 not being available in several countries. The Pixel 4 was also the first Google device to come with a dual-camera setup. There is a 16MP telephoto camera with a 2x optical zoom alongside the usual 12MP sensor.

As we've seen over the years, the Pixel's camera prowess is all about the underlying software. Among the bevy of camera improvements, Night Sight received a significant upgrade. Night Sight debuted alongside the Pixel 3 and is second to none (except Huawei, maybe) when it comes to low-light photography. With the new astrophotography feature baked into Night Sight, Pixel 4 users can now capture the night sky in all its beauty.
