To scan a document or image, open the Google Drive app and tap the scan camera icon. Alternatively, you can click the plus icon, select "Scan," and use your camera to capture the image.

Alternatively, if you see a search bar on the apps list page, look up "Drive" and tap on the correct app icon. You can also pull up the app drawer and search for Google Drive there.

The process of using this could not be easier. Download the Google Drive app, sign in and open. Then select the document icon above the plus sign in the bottom right.
