So I just got my shiny new Lumia 800...
...and the camera won't focus.
No autofocus when taking shots, no manual focus when half-pressing the camera button.
Hey Billbennettuk, Welcome to the Nokia forums!
The Lumia 800 has a touch screen focus, is it this feature that is not working? Have you tried shooting in other camera modes?
If the camera is not focusing or not responding at all to the touch focus, it might be worth backing up all your information and doing a hard reset to fix your problem.
I hope to hear back from you soon, please get back to me as to whether or not you get it up and running again!
