At the beginning of the month HTC One X owners on AT&T received a new update for their devices, and now a similar update is coming to users in Europe as well. It brings the device up to Android 4.0.4, and includes improvements to the HTC Sense experience and browser performance, as well as new camera features like white balance and continuous autofocus. And just like on AT&T, you can also now map the menu function to the recent app button, which should make for a much improved experience. For Facebook users, the smartphone now only requires you to sign in once to access the social network across multiple apps, and aside from that, owners can expect the usual assortment of bug fixes and performance improvements. We haven't seen the update on our One X in the UK just yet, but HTC says it will be rolling out today.
