Hi, my friend bought Lenovo A6600 plus 12 months back. I had an experienc in this mobile, good as per specifications but I don’t like build quality. My friend and me replace it’s display twice due to poor quality. While I am working it’s get hang and shutdown automatically. The OS complaints is another problem of this mobile. The sound quality I like it because it design with dobly. The camera quality is not good as per specifications, it gets heat while I play games. The quality of body cover is too bad. I recommend to try some other.
