    Dear All, I have problem with opening camera. It says "Cannot connect to the camera. Please make sure to close all apps that may use camera or flashlight" but closing all app does not help. First time it was possible to open camera when I was clear cash of gallery and similar app but as soon as Iclose and open camera it was the same problem again. Factory reset and rewriting firmware did not help. I have found crash log file and here below copy of log file text:
