There are DHGate reviews that you can read and decide. My step brother had a Blu Life One that cost 99 bucks and he thought it was on par with his prior Samsung. You are looking at 3 or more times that price so I'd ask why the N4 here. Have you used one? Some try to replace what they do on a PC with a cell phone and it's hit and miss. That is, some like it, others regret it.

Since it's Android, I like to pick from http://www.amazon.com/Best-Sellers-Cell-Phones-Accessories-Unlocked/zgbs/wireless/2407749011 in the 99 to 199 price range.
