Android phones with improved proximity sensor

I am currently using the HTC Wildfire proximity sensor. The problem is that it only returns a boolean if there is an object within 1 cm in front of the sensor.

So, I want to ask if there is an Android phone on the market that has a proximity sensor that can return actual distance values ​​(cm) instead of Boolean ones.

thank

Yes, you can get the actual distance from the surface of the phone.

In fact ALL hardware DO sensors provide this information. But, unfortunately, the touch API defined in Android determines the proximity to boolean ie NEAR (1) OR FAR (0).
