The level of complaints seems to me to be about the same as most new phones. Understand that most people don't post on forums like this one to say "Hey, I have no issues with my phone." People join, and post, to search for answers when they do have problems, or sometimes just to complain.
I've read this and other forms before buying all my phones, except this one. And I've thought, "Lord, this phone is terrible." Then got mine and found it worked perfectly fine.
