I have been using this phone from past 4 months. till now there is no problem with the mobile. camera quality is very good. the video is very good, we can also capture clear video at night using 3 led flash.The battery back up is acceptable for this phone. Now I am getting 1.5 days backup with music. The build quality is very good and solid body.
The only dis advantage is its a slider phone, because slider phone will give problem with slider after some time. better to use bluetooth head set for better life and better performance.
