Too much heating when data is in use on wifi 3g/4g. The sound quality is too poor even I cant hear when its ringing during travelling in bus or train .
The mobile has another problem regarding dual sim slot feature provided for good reasons but from last 8 months the sim slot 2 is not working.
This failures are found after 6 to 7 months after using the mobile and I am giving this review on not any another phone.
