I dropped my Motorola Charm (Android 2.1) and the proximity sensor doesn't work which is annoying, it makes the the touchscreen disabled when I dial anything (super annoying).

I would rather like to disable the proximity sensor, so it will never disable the touch screen.

Does anybody know how I can do so?

In case of absence of any ready made solutions, I am even willing to write my own app for that (there are programs that do that but for Android 2.2).

If all other readymade solutions let you down, you can do a small app that will do exactly as you asked. Please see this StackOverflow question which talks about the same. –  Narayanan Dec 4 '12 at 9:32

You need root and an app called Hardware Disabler from Google play. See also here –  ce4 Dec 4 '12 at 9:34

Let's keep this focused on app or similar solutions.... If you're looking for a code solution, you may wish to ask this on StackOverflow –  Bryan Denny Dec 4 '12 at 13:56

The first review of @ce4's suggestion looks to fit your case nicely: For me, this is very good app. I found that my proximity sensor is not working and the phone app is freezing because of it so I just found propriate drivers with other app and disable them with Hardware Disabler... Works like a charm –  Matthew Read Dec 4 '12 at 16:06

Motorola CHARM has a proximity sensor located on the upper left corner; as stated in Motorola CHARM product support site, external lighting conditions will affect this sensor.

Motorola CHARM proximity sensor location

My suggestion is: each time you need to use the touchscreeen while making a call, try to "trick" the proximity sensor illuminating it with a flashlight or LED, so the sensor "thinks" that you've moved away the smartphone, thus re-enabling the touchscreen circuits.

If you don't have any of these items on hand, look for a place with bright light toward which to move yourself/your phone.

hahahaa it would be really funny carrying a torch with myself to make my phone work, people would think I am crazy. –  Medya Dec 28 '12 at 7:27
