Need help. My wife and I both have the Note 4. Since the update to 5.1.1, neither phone will focus correctly on items when using the camera. She is trying to take pictures of our kids and I try to take a photo of a check for mobile deposit and they turn out very blurry. Neither of us had any issues in the past, this just started since the update. I just did a factory reset on my phone for a work related issue and still have the same issue. I didn't reset my wife's phone since that didn't fix my issue. I also cleared cache on the camera and cleaned the camera and still have the same issue. Seems like this is a software issue, but I wanted to see if anyone else has seen this issue. Samsung wants me to send my phone in, but obviously I can't do that as I can't be with out my phone for 2 weeks while they "troubleshoot" it. All they will do is reset it again and send it back.
