A few of Google's most popular photography features are making their way to iOS and Android devices for users who subscribe to Google One. Previously, the tools — including Magic Eraser — were exclusive to Pixel smartphones. The company launched an extensive campaign to market its Pixel-exclusive features following the release of the Pixel 7 and Pixel 7 Pro last year. However, in a surprise move, Google announced that it would be bringing some of these perks to Google One subscribers in February 2022. For current Google One subscribers on non-Pixel devices, that's great news.
