Questions and Answers

Optical reader closes as soon as I open it?

When I open OR, a window appears saying "Additional files will be downloaded so that you can use Optical Reader" When I press "OK" the app shuts down. I've never been able to use this app.

One way to refresh this application, is to go into Application Manager and clear all cache, stop process and clear data. You can perform this by doing the following:

1. Go to Settings.

2. Go to Application Manager.

3. Find Optical Reader.

4. Clear cache, data and stop the processes.

Revisit the app for use after performing these steps.

How do I scan QR codes using Optical Reader?

I can scan, capture and translate text, but nothing happens when I have the pointer aimed at a QR code.

The Optical Reader's main function is to make use of Samsung Galaxy S4's camera and read the information contained. For QR codes, what you basically need to do is make sure you focus your camera on the code and a URL link will appear. When the link appears, you can choose whether you would like to browse it right away through a browser, add a bookmark for it, or share it.
