If your rear camera is taking fuzzy live picture when zoomed or in live focus mode!!! It's the rear camera it's d3fected, I've had that issue for 4 months. Got let down by Samsung who required me to mail in my only phone. So I spoke to a friend who works for Ubreakifix and he said he think it's the camera. I have him my phone to replace the camera which only took 3hrs unlike Samsung 1 week service that requires your phone to be shipped. And the conclusion is that it FIX THE PROBLEM THAT TURNED OUT TO BE A DEFECTED REAR CAMERA..... UBREAKIFIX IS STAR HERE
True. Had mine replaced last jan and now it is back to it's usual buzz. Samsung told me that they can replace the module again since I'm still under warranty. Thinking of doing it just to get it fixed then I sell it and replace it with maybe an i.. or H...? Whatya think @samsung?
