I bought Lenovo A319 in may of 2015 . it is a 3G phone and at that time we were satisfied with 3 phones also. it worked well for few months but after few months it started giving me problems. video gets stopped suddenly and gallery suddenly stopped and pop up appeared that gallery stopped unfortunately . after few months its display suddenly turned black and when I went to the customer care office, they asked for lot of money . Otherwise its style and design is good but nothing to do with that if its internal features do not work well.
