Update [April 21, 2017]: PhotoScan by Google has received a new update that makes it easier to take glare-free pics. Earlier, you had to take multiple pictures to make sure the picture was glare-free, but now, if you feel the lighting is right and you don’t need the glare removal option, you can turn off the same and scan the picture with just one tap.
If you are worried that by turning off the glare removal you would lose the access to other key features like cropping and edge detection, well, that’s not the case. You still get to use them.
In addition to that, you don’t have to open the Google Photos app to share the pictures, the update allows you to immediately share your scans right from the app.
Launched in November 2016, PhotoScan by Google allows you to scan your printed photos using your phone’s camera and saves them on Google Photos.
