2018-05-05 00:00:00 OCR Libraries need to be downloaded at the first time of launch. Please keep the app open for almost 1-10 minutes (depending on your network speed).The libraries are downloaded by 'GooglePlayServices' app and didn't provided any way to see the progress.. Sorry for the delay.. search for text in books and documents by placing the camera above the page. It shows a box over the item if the search item is found.
