I was personally using Oppa A57 for 2-3 month and later given to mom. Compared to me she was using better then me. she dont use much applications. It was music camera and call may be because usage was mint. But bad part was screen resolution is coming down day by day. And already service twice for issue back to back weeks. My Oppo A57 is amlost a year. Till my the issue of touch and display was cleared under warranty. Now warranty is about to finish and im worried for mobile. From few week I have faced touch problem and display issue. And warranty claim took 2-3 days. I have already face issue twice and now I dont have trust on Oppo. Because we cannot change mobile every year. I was expecting good support and product from Oppo. They need to come up with Good quailty product as well service. They need concentrate product quality not only sells. Service is important for any product and qauilty matters. Now if my mobile go faulty or bad I cant come and buy again Oppo because I have faced problems and expierenced it. I suggest or reffer friends of others. This was my personally using expierence on Oppo A57
