I know lenovo is the branded company and launched many awesome mobile but lenovo A6600 is not awesome mobile its have only 1GB ram its camera quality also not so good but its battery is really good. I likeed its body and I thought it would be a good mobile but even its fine mobile I can run this mobile for 2year easily without getting bore. The bestest job of this mobile is that this 4G phone and I dont need to buy another phone for 4G speed. Its sond features are good its speaker doing good job.
