In devices with the Android operating system like the Oppo R7 there is still no built-in functionality in the operating system itself to scan documents but luckily Google has a solution for this problem.
Your R7 comes from the factory with the suite of Google applications, including Google Drive, if you don't have it installed you must download it from the Google Play Store and you will be able to scan papers as if it were a regular copier or table scanner only with the camera of your smartphone.
Estimated time: 2 minutes.
