Lephone is a chinese company . so we did not any guarante on china company mobiles . china mobile companies did not give any warrenty and guarante to their products. In this mobile its RAM is 1gb is very low , so their is a chance to hang of mobile phone . Its battery capacity is 2000 mah battery so it not work more time because of this low battery capacity. so we have to buy any other mobiles with this price.
