Google began rolling out its Google Lens tech to Android phones back in March, allowing third-party smartphone owners to update the Google app to directly integrate Lens into a device's native camera app. 

Now Sony’s latest phones will finally include that option as well. Owners of the Sony Xperia XZ2 and Xperia XZ2 Compact will no longer have to open the Google Photos app to access Lens features, Sony announced this week.
