Yes Timmappa, I searched for it again, and found that this QR BARCODE SCANNER Code Reader which can do the following things:
Scan QR Codes And Barcodes from
Camera, Image Files and Urls. You can also Create Your Own Qr Codes Encoding, Create Your Own "oldy" Barcodes (EAN8, Ean13, Code39, Code 128), Share your Qr Codes through email
text messages, social Networks (Facebook, Twitter, Flipboard, Google Plus). It has Wifi and Bluetooth with Auto-Archive Every Qr Code which can be Decoded through a very simple History List. You can also jump directly to the Web Addresses that has to be Decoded.
You can perform Continuous Scan, use its Flash Light.
What I guess that the Update that you have installed might not have installed properly or might be conflicting with some features of your system.
