Like any Android phone out there...you have to wait a few seconds for the phone to actually fully turn off. Android is based off linux...so when the screen turns off...it really isn't fully turned off...the phone is actually still shutting down. I wouldn't say your phone is bad...it may just be a app or program that is causing it to hang while shutting down. Try doing a Hard Reset of the phone or remove some apps that you installed since finding this issue. Then if that doesn't help...Hard Reset it...and see if that solves your issue. Worst case..the phone is defective and you need it replaced.
