I am using this mobile since last one year so I will give you a short review on this mobile. This mobile never hang while using. I am using this mobile since last 1 year but till now it does not get hang any time. Even my phone storage is full and I am having 250 group in whatsapp then also it doesn’t hang. I like this type of mobile which doesn’t hang. But there is problem also and that problem is that my second sim card network is not constant. Network will not come till I select the network option so this is the major problem in this phone.
