"Thank you for contacting HTC regarding your HTC Desire S.
My name is James and I am a Technical Support Agent for the HTC Written Team.
Iím sorry to hear that you are experiencing difficulties with the proximity sensor.
I would first ask you to try a soft reset. This is done by removing the battery from the phone while it is still powered on. Leave it out for 5 minutes and then put the phone back together and switch it on.
If you still then have issues you will need to hard reset the phone.
The hard reset will delete all data from your phone so its advised to back up.
Have you downloaded and installed the "HTC Sync" application?
This is a free download from our website - HTC Support Center
and must be installed onto the PC before you can connect the phone. Once it is installed, reboot your PC and when Windows has finished loading up connect the phone using the USB cable.
Once you have backed up please follow these steps to hard reset.
There are two ways to reset the handset to factory settings:
1) Please press MENU from the home screen, then tap Settings > SD & phone storage > Factory data reset > Reset phone, or
2) With the phone turned off, long press the VOLUME DOWN button, and then briefly press the POWER button.
Wait for the screen with the 3 Android images to appear, and then release the VOLUME DOWN button.
Press VOLUME DOWN to select FACTORY RESET, and then press POWER.
When asked to confirm, press VOLUME UP.
