If you’re one of the lucky ones with a new HTC Desire HD phone you may have noticed there is a rather annoying bug related to the proximity sensor.
Basically, you make a call and the screen immediately turns off and becomes unresponsive
It seems like the phone has crashed but it continues to stay connected and make the call. None of the buttons work such as the ‘home’ button and the only way to ‘wake up’ the phone is to plug in a 3.5mm jack to wake the screen up or just take the battery out
In the longer term, you should update the software. To do this, connect to a WI-FI network then:
Go to ‘Applications’ > ‘settings’ > ‘about phone’ > ‘System software updates’
‘Check now’ for updates then install any available software updates.
The phone will download and install the update then restart after a few minutes.
