Iam using this mobile for more than 3years. It works awesome. This is worth of buying at this range of price. More than 2years my phone does not hang or lag. Totally addicted to my phone. Because of stunning performance of my phone. I have no words to explain how my phone was worth. It is totally an awesome. People who are buying smart phones below the range of 6000 I suggest them to buy an awesome phone that is lenovo A536.
