Sound .
I am using this from 8 months .it is a very very bad mobile there is no secondary speaker for playing music.
No loudness no ringtone clarity no movie experience.
User freindly.
This is typically a 3 G mobile and with 4.5 inch screen .touch is smooth but not that fast so valueless.
Display.
Bad display.
Camera.
Very very bad one.
Overall I can say don’t buy it
