Before a few time I bought a I ball And 4.5 Ripple 3G. In starting this cell is work smoothly and very smartly but after sometime it was going to hang.it was not work properly and due to this problem sometimes I couldn’t take call in imergency situations .once I I was going through my bike and due to rainy season I was drop therefore I want to call my friend Tushar to pickup me and that time when I was going to call from my this mobile to my friend it was completely hang during that time.company gave already some useless application which are the main reason for hang of mobile. In recently every mobile company gave fingerprint but this feature is not in your mobile so ultimately your mobile is not user friendly and further I will tell my friends not to buy this mobile.
