The camera on my LG G3 D850 has been acting badly lately. When I open it, sometimes it will work for a few seconds, then gets these purple lines across the screen, and usually crashes. Sometimes it won't work at all. This only happens with the rear facing camera (front-facing works fine). I have cleared cache/data, tried to reinstall camera app, even did a factory reset, all to no avail. Has anyone seen this before? Is there any way this could be software and not a hardware issue?
