The previous generation of Motorola DROID models, including the Motorola DROID RAZR HD and the Motorola DROID RAZR MAXX HD, are still on the fence. Checking Motorola's website for the manufacturer's update intentions for both models shows that Motorola will soon announce its future plans for the handsets. Both of those phones are currently powered by Android 4.1.2, so it would take quite a huge leap to update the pair to Android 4.4. As a result, don't expect to see Android 4.4 on the DROID RAZR HD or the DROID RAZR MAXX HD.
The Motorola Moto X will be getting updated to Android 4.4
