I am using this mobile since 3 years. And on this 26th dec. will become used for 4 years. First of all, this mobile works properly but only for few moths after buying. Only 8 to 9 months it will work properly. But after that you will face little problems. And it will start hanging alot. And after sometime will go you will feal like dumping it into dustbin only. Because even if you will try to sale it on OLX then also NO one will buy it. Because everyone is aware about it now. That it hangs alot. And I need to formate it approx. After 15 to 20 days again and agian. It stucks your mind. Be. Cautious before buying this mobile phone. I will suggest to buy Oppo, panasonic, Motorola's mobile phone. As compared to this mobile phone. They will be cheaper and will work better then galxay grand. You will enjoy using other mobile phones. But don't even think to us this mobile phone.
