I like Sony products very much but this time I disappointed slightky . This is because if internal memory. It is just 1GB and not able use many apps at a time. Another drawback with this is front facing camera. I am using this mobile since 2 years there is no issue with battery and sound.
Pros:
Excellent sound quality.
Big display.
More battery backup.
Sony brand guarantee
Cons:
Internal memory.
Front facing camera.
