Phones are getting better video and photos for Instagram, some older devices are getting Circle to Search, and a new next-gen Call Screen is coming to the US.

Pixel watches are also getting a fair bit of attention, with Google adding a new pace trainer and heart zone trainer, plus automatic workout detection, and a way to wind down once your workout is done.  

The update will be available for all supported Pixel phones, tablets, and smartwatches. It starts rolling out on March 11 in the US, and March 4 for the rest of the world.

Here's what you can expect.

New to Pixel phones in March

• 10-bit HDR video and Ultra HDR photos for Instagram: Want your social media to look its best? You can now share 10-bit HDR video and Ultra HDR photos, both of which provide brighter colors, better intensity, and higher contrast, Google says, straight to Instagram. These features are coming to the Pixel 7 series, the Pixel 8 series, and the Pixel Fold.

• Circle to Search: After coming to the Pixel 8 series last month, Circle to Search is now headed to thePixel 7 series. By long-pressing on the home button, you can draw a circle around an image, highlight it, or tap an image to find out more.

• Next-gen Call Screen: You can now use Call Screen to get a conversation started when the other person is silent. If you answer a call and the other side isn't saying anything, tap the "hello" button to start a clip that asks why they're calling. Also, if you answer a call with your screener, but need an extra second to pick up, Assistant will now let the other person know to hang on a moment. This feature will be available on Pixel Fold,Pixel 6 , and newer phones only in English in the U.S.

• App screen sharing: Want to share your screen without sharing too much information? On the Pixel Tablet,Pixel Fold , Pixel 5a , and newer phones, you now have the option to choose one specific app to cast or present, instead of sharing everything.

• FastPair subsequent pairing: If you often switch between Bluetooth devices, you'll now find connecting to the device you want a little easier. Tap on "Previously used with Account" on your connected devices settings page, and connections you've previously made are shown. You'll find this feature on the Pixel 5a and newer, Pixel Fold, andPixel Tablet .
