I have been happy with mine except for the antenna (Also had antenna issues with gs3 and every other samsung phone at my house) The battery isn't the greatest either.

I am going back to Motorola, My wife's Razr M picks up far better at my house and my Friends original Razr has 3 bars of 4g and the samsung devices I have had in my home have a hard time even holding a 4g signal in my house.

My htc picked up better as well.

I love my Nexus, but I am done with Samsung when I buy a new phone. I think I am heading to the Razr HD MAXX. Or might even be adventurous and check out the new BB devices.
