Hi everyone! This is my first post so i hope i will get some help. I have T-mobile touch with android on it. I want to use Barcode scanner, but when i turn it on, the screen is black, and all i see is that red line on the center. It's like my camera is not turning on. I also tried on my cousins phone (exactly the same) and the Barcode scanner app worked fine. I tried many times all over again but the problem is the same everytime. BTW when i try to take photo my camera is working fine. Please give me some help. Cheers.
