I absolutely love the camera on my Note 4. It's one of the best smartphone cameras out there, and it takes fantastic pictures in almost any setting. I take a lot of pictures, mainly for work, so having such a capable camera on a mobile device is fantastic. But over the past month, I've increasingly run into an issue - the camera won't focus on objects more than 6 feet or so away (macro shots are fine). It's not always a problem, but I'd say about 25% of the time, the camera just won't focus on objects that aren't right in front of it. It will focus for a moment, then it will go blurry. It doesn't matter what camera app I use. I've even done multiple FDRs, but nothing has fixed it. The issue started before the Lollipop update, so it's not related to that. So I did some digging online, and it seems that several Note 4 owners have run into the same problem. The only way they've been able to fix it is to get a replacement device. I called up Verizon customer service today, and sure enough it is a known issue. Neither Verizon or Samsung have a fix for it beyond replacing the device. So a certified like new replacement Note 4 is on its way to me. I've had great experiences with replacements from Verizon in the past (they all looked and performed as if they were brand new), so I'm hoping for the same here. Here's the moral of the story - if you experience problems with your Note 4 being unable to focus when taking pictures, it's a known hardware issue. Get it replaced under warranty.
