Firstly, I tell you my personal experience on Nokia N9. I am purchased this phone around 5 year ago. This is my first phone which I used .and nokia N9 phones style and designe is very good.i like it, it’s sound quality I like the most, I used this phone 2 years I doesn’t had problems in that time but I used another phone just because in this phone I am not able to download social networking applications, not able to extend its memory, there are no place for external memory card, its camera quality is awesome. But this phone is hopeless for me just because of not able to surf on social networking applications. That’s why it disappointed me. It’s secondary camera I also not able to use by camera application, for secondary camera I downloaded one other application to use it.
