How buggy is this phone?

I have not had any issues with it. I do like the phone a lot. There could be issues, but I have not come across any so far.
 
I had it since yesterday but so far really good. One thing that I like is that I can use my zagg earbuds with the screen locked which I couldn't do with my lumia 900.

It seems like the Titan II is shaping up to be the least problematic of the second gen devices.
