Note 4 camera not focusing New galaxy note 4 camera doesn't focus at first,  it will only work when I shake my camera or thump it real hard.  Had anyone had this issue or have an idea on his to fix it?
This is a common issue on Note 4s running Android L. The most common suggestion seems to be a replacement, as the issue is not software based but actually a loose sensor within the phone itself. I suggest contacting your phone service provider.
