So for reasons I won’t get into, I have a faulty main camera on my Samsung Galaxy S III.
It turns out Snapchat still allows me to take pictures and save them without crashing, due to it having front camera on by default. But I found myself needing a barcode scanner or QR Code scanner for 2-Factor authentication.
Most barcode scanner apps, which automatically boot into scanning mode will just crash straight away. I spent quite a while trying poorly written bar code scanners (even the one Google Authenticator suggests) which just crash if the back camera is broken.
Eventually I found a solution. QuickMark Barcode Scanner doesn’t crash right away and allows you to switch to your front camera. It has a pretty decent UI, and they also have a pretty good Windows app for scanning barcodes on your screen. Good job on the developers for handling erroneous situations gracefully.
I wish Whatsapp would listen. Because of a defective rear camera on my phone, I cannot read the Whatsapp web client’s QR code.
I write Whatsapp support and they reply like they’ve never heard of this ever happening to anyone.
quickmark barcode scanner is no longer available Jason (the link isn’t going through), do you know any other solution.
You could try their site, but looks like it hasn’t been updated since 2013. Not sure what else to try – Sorry!
