build quality ?@#

[Lukas718]

My 1st one TP was build on 10/14 - and had a lot of problems
then my 2nd one was from 10/13 and had none - I loved it - it felt like build quality was great but yesterday I dropped it from my bad and chrome around the top just cracked.
I went to bestbuy and got my exchange (build on 10/29/0 but new one has new problems. It feels like it lags a lot, battery cover is loose, sometimes buttons on the phone stay on and it already froze.

Can they all be sooo different ? or am I going nutzzz ?

or both hehe
