Android Market now shows which handsets are compatible with each app

Now you can make sure that your Android device is compatible with an app before you download it on your phone. The Android Market has added a device compatibility check that you can access before pressing the install button.

With the new feature, those wanting a specific app on their phone won't have to read the text that is posted in the Market. Sometimes longwinded and too much of a hassle to go through, some developers slip in which handsets are compatible with a specific app, but like the fine print on a contract, it doesn't get read. The addition by Google of the device compatibility check will save Market users time and eliminate the aggravation of having to uninstall a recently downloaded app because it doesn't work on your phone.
