We downloaded so many apps to scan our documents.
But its not needed as you can use Google Drive as a good scanner as it can scan multiple pages simultaneously like dedicated scanner .
You only need to go Google drive>
Click on +Plus icon>
Click on Scan (and if u use first time give some permission)
Then scan ur documents, after one page done click on +plus icon at left bottom corner to add 2nd page and so on as you like.
