Get help when you need it
Need a hand? No problem. Pixel 4a has a built-in Google Assistant to help you along the way. You can use it to control your phone, send texts, open your favourite apps, multitask and more.
Let your camera do the work
Take perfect photos, day or night. When the lighting isn’t great, you can adjust the brightness and shadows separately, using dual exposure controls. And Live HDR+ gives you a preview of how your picture will look before you take it.
Keep going for up to 24 hours
The Pixel 4a’s Adaptive Battery can keep your phone going for up to 24 hours. It learns your favourite apps, so you’re not wasting battery power on the ones you hardly ever use.

With Night Sight camera mode, Pixel 4a lets you delve into the world of astrophotography, and capture incredible pictures of the night sky.
