The new Google Camera app for Pixel 3 phones touts a lot of widely publicized features like the wide-angle selfie camera and updated AR stickers, but another lesser-known feature is that it can add a remote viewfinder to any smartwatch running Wear OS. The Google Camera Wear OS app also adds a timer and flip camera button. The new feature was first spotted by Redditor AimarChirico, via Android Police.
The feature is a big improvement over the last Wear OS Camera app, which only allowed for remote photo taking. It seems particularly useful for framing photos taken by a phone set up on a tripod. The viewfinder feature also reportedly works with your phone screen turned off.
