My Lumia Icons camera autofocus just stopped working. I watched to Microsoft camera... Won't focus. Uninstalled Nokia camera. Installed Lumia classic camera. Won't focus. Ugh, help crying
Did you try a soft reset of your phone. Give that a try and let us know how it went.
Soft reset is done by holding down the volume down and power button for about 15 seconds. You will feel two vibrations while doing this. The first is almost immediate; keep holding down the two buttons until you feel the second vibration and then release both buttons.
