When you choose to save the scanned image, you will see many options – save to OneNote, OneDrive, PowerPoint, PDF or Gallery. It shows you the output and allows you to rotate, crop, resize the scanned image. Then point the camera to the document, focus it by tapping on the phone screen and then touch the camera button to take the picture aka scan the document. You can also choose a resolution for the scanned output. It could be a document, whiteboard or just a picture. In the app, you can choose what type of paper you are going to scan. This is why you will have better results if your phone has auto-focus camera with high resolution (more than 8 mega pixel is good). Office Lens is an Android app (also available for iPhone, iPad and Windows mobile) that scans paper documents using the camera. And now Microsoft has also released an app called Office Lens which also does a similar job. We have previously reviewed CamScanner app for Android that is able to scan documents using the phone camera. Android smartphones with 13 mega pixels resolution have become commonplace now. These cameras can capture the picture with so much detail that they can be used for virtually scanning documents and whiteboards instead of using a traditional flatbed scanner.

These days newer smartphones are coming with very powerful built-in cameras that have very high resolution.
