I have a big question here. It has been wondering inside my mind for quite a long time already. I'm planning to change a new phone but I don't know which model to choose.

My requests:

1. Nokia Brand
2. Smartphone
3. Touchscreen
4. Camera 5 MP above
5. Secondary Camera
6. Bluetooth
7. Wi-Fi
8. GPS
9. Video Call
10. Java

I have interested in:

P/s:

Which phone model is the best choice?? Please share your opinions with me. Thanks.
