Sensation 4G owners on T-Mobile should start receiving notifications that system software 1.45.531.1 is available for installation, bringing the smartphone up slightly to Android 2.3.4.
What will the update bring to the platform? For starters, there's the usual claim of better system stability, along with a somewhat increased battery life. There are also a handful of graphics-related changes, including improvements to the appearance of icons and a more responsive screen (it's not clear if we're talking just about the display, or about more responsive touchscreen input). There's a curious mention of "improvements to screen/photo resolution"; again, we're not sure what's meant here, since software can't do squat to change the screen's hardware resolution, but if it makes things look nicer, so much the better.
The Swype-like Trace keyboard gets smarter with a new dictionary, WiFi should be more stable, and some minor bugfixes to video playback and power cycling help round out the update. T-Mobile says that, although distribution has already begun, it could still be several weeks until all users see it arrive. The carrier expects to complete distribution by the end of September.
