Google has added a useful feature to its Google Photos app for iOS. You'll be able to tweak background blur levels and adjust the focus on portrait mode photos. The depth editor tool is arriving on iOS soon after Google added it to the app on Pixel 2, Pixel 3 and some Moto phones. Notably, Pixel 3 phones have a built-in depth control feature, as do iPhone XS and XS Max.

Just pull up a portrait photo in Google Photos, click the editing icon to get to the editing menu, then tap it one more time to edit depth and focus.
