The Nexus 5X will start at $379, while the Nexus 6P will start at $499.
The new Nexus 6P is the first Nexus phone to come with an all metal design. It has a 12.3 megapixel camera and a 5.7-inch display. The Nexus 5X is a smaller phone with a 5.2-inch screen.
The image above shows what the Nexus 6P looks like, and here's a photo of the Nexus 5X:
Google is really talking up the new cameras on its Nexus 6P and Nexus 5P. The company says the camera in the 6P has larger pixels, which means its optimized for indoor photography. Both phones can shoot 4K video and slow motion video.
There's also a new Android Sensor Hub in both phones. It tracks movement, which means it can automatically turn on the display when you pick up the phone.
Both phones come with a fingerprint reader that Google is calling the Nexus Imprint. It performs with a "low false reject rate," Google says, which means it should be extremely accurate.
Google is throwing in a 90-day free subscription to Google Play Music as well. All Nexus preorders in the US come with $50 in Google Play credit, too. Both phones will work on Google Project Fi network.
