HTC have just released a software update for the Sensation and Sensation XE. The update, which is described as an “enhancement” update is around 60MB in size and takes around 5 minutes to install. It is listed as version number 3.33.401.6 for the Sensation and 3.33.401.106 for the Sensation XE.

HTC have been rather vague in any improvements/updates that have been implemented. As far as I can see, these are the changes:

• The “Android is upgrading” phase that occurs when rebooting the phone from ‘cold’ has been removed. The phone no longer attempts to optimize apps when starting up. This appears to have drastically improved boot time – now around 20 seconds from power on.
• The autocorrect keyboard has had fixes implemented now meaning it works properly again with apps such as Twitter (it stopped working after the initial release of ICS for the devices).
• Spelling corrections in the UI – e.g. “develop option” now rewritten as “developer options” in the Settings menu.
• The device now responds much faster from sleep – the initial release of ICS left the device taking 2-3 seconds to respond to a wake-from-sleep request in some instances.
• Bluetooth streaming appears to have improved on my initial tests – the bitrate of Bluetooth streams was dreadful with the initial release of ICS but now seems to be better, although only time will tell if this is actually the case.
• ADDED: My phone no longer spontaneously reminds me every so often that it is up to date and that no updates are available.

However, some users are already reporting major issues with Wi-Fi on some devices since the update. According to some users, Wi-Fi will no longer connect properly (especially over longer ranges). I’m not personally experiencing the issue but will report back if I start to run into issues.

Most stock Sensation/XE users should be able to update OTA now. If you’re using a network supplied phone, it may be a little while longer before you receive the update.
