I tested a simple application that gets the Lat Lon Info and displays it onto the screen.
It is working fine on an emulator , However when I tried it on my samsung GT-M5650, it is not able to retrieve the info.
Location Services is a special JSR subsystem. It is not part of ordinary JME. Not all devices implement it.
That means that the first thing you have to do is make sure that the device in question even implements location services.
GPS is often turned off by default, since it's a significant power drain. In fact, for some phones, the carrier permanently disabled the hardware. Since Location Services allows selecting a "best-fit" location service provider, that usually allows apps to fall back to less-precise techniques, like using the cellphone towers to do trilateration. However, it's possible that some phones wouldn't have that option. The actual GPS hardware (where available) usually has to be powered on by a separate control panel function. I don't think there's a Java API call for it.
Customer surveys are for companies who didn't pay proper attention to begin with.
