The Lumia 920 front camera is very easy to be grayed out. Many users complain that Nokia has found a solution.
The Nuo plan plans to upgrade the process of the Lumia 920 that will be released later, and add a protective layer around the front camera to prevent dust. Users who have purchased Lumia 920 will be able to send the machine to Nokia after-sales service for dust cleaning and installation of protective layer.
