HTC One X Update Rolling Out
The first software update for the HTC One X has begun rolling out. The 30mb OTA update is available for unbranded HTC One X handsets, with network branded handsets to receive the update at a later point in time. The update brings with it an adjustment to the auto brightness, improvements to battery life, and other minor fixes. Unfortunately, a fix for the launcher restart and browser lag issues is noticeably absent from this update.
