I had this armband for my Droid 4, but it's a bit small for my Maxx HD. It's a bit too tall for the armband, and the light sensor is covered, so the screen is at it's darkest all the time, which is a problem for using it while on the run. Do any of you use a good armband for your Razr HDs or Maxx HDs? I'm in need of a good new one. Thanks for the help!
