I have buyed this phone in April Month of 2015. I am reviewing it after continuos use of 1.5 year. Till date I am not facing any problem and need not to visit any service centre. Hence I recommend only lenovo. According to me if you are planning to buy a phone then buy lenovo. A problem with this lenovo A7000 phone is that it does not support VoLTE( Voice over LTE) under which calling is not possible with JIO sim in this model of Lenovo phone. Hence, keep this in mind before buying it. Overall performance is best. And valued deal for money.
