You no longer have to fire up Google Photos if you want to use Lens searches on your iPhone. Google has rolled the AI-based feature into its iOS search app, putting it in a more logical place than your image library. Tap the Lens icon in the search bar and you can point your device camera at books, bottles, pets and various other objects to get more answers about what you see. You can tell Lens to look at your existing images or turn on the flash when it's too dark.
