Lumia 920 Having Auto-Brightness Issues Post-Update?

Microsoft’s Windows Phone 8 build 10211 “Portico” update hit Nokia’s Lumia 920 in the US and Canada earlier this week, delivering some eagerly-anticipated fixes, like one that sharpens-up the handset’s camera. As we’re all too familiar with seeing when updates arrive, though, this one may introduce some new problems of its own. A number of 920 owners have been reporting that, following the installation of the update, their phones seem to have problems managing screen brightness levels.

What we’re hearing is that these affected handsets keep fiddling with brightness levels in areas of average illumination. When the phone doesn’t need to be fully bright or very dim, it keeps fluctuating its brightness setting, changing several times a minute.

One theory claims that this is a calibration problem with the phone’s ambient light sensor, and it can be remedied by first powering-on your phone in darkness. For the moment, we can’t say for sure if that’s all it takes to nip this problem in the bud, but if you’ve been noticing the brightness on your phone has been a little wonky lately, it’s worth a shot.
