Issues possibly to me there are parts of this OS thats not all that great:
Read the following: I replaced one of those phones, I bought a Droid Maxx and shortly after I got it the update which there was two it wanted me update I took the one it went Ok it then wanted me to update to Kit Kat so as the wit the first update I updated to Kit Kat and after I did my phone started having connecting issues and the Camera was taking bad pictures compared to pictures it was taking when it was still on Jelly Bean which I was able to take before I done the updates, So I took my phone to a Local Corporate store it was DOA'd out and I got a new one and it doesn't have Kit Kat on it so Motorola or Verizon may be holding off on Updating Razr Maxx HD) because of Issues similar to what I was experiencing..
So as it goes hopefully something will come out soon!
