The Motorola Photon 4G has just received a pretty sizable maintenance upgrade. Alongside general fixes and enhancements, we’re getting Google Talk video chat support, support for the new Lapdock 100, a fix for the erroneous proximity sensor and more. Lookout for build 45.3.6.en.US when checking for firmware upgrades in the settings menu. Don’t fret if it doesn’t immediately pull the update down as Sprint has likely employed a staggered rollout.
