Using Google Lens on Android

  1. 1
    Get the Google Lens app from the Google Play Store . Many newer Android phones come pre-installed with this app, so you might not have to re-download it.

    • Search "Google Lens" in the search field (which is located at the top of the page in the Google Play Store) and download and install the free app offered by Google.
  2. 2
    Open Google Lens. This app icon looks like a red, yellow, blue, and green outline of a camera lens that you can find on one of your Home screens, in the app drawer, or by searching.

    Tap the photo gallery icon. This is the icon of a picture that you'll find in the upper right corner of your screen, to the left of the three-dot menu icon.
