Paid for an official Samsung screen replacement at an authorized center, and in just one year, I have the green line defect. Center is refusing to help because of device age, even though the panel itself is new. This is unacceptable since the phone does not have any physical damages. They told me I have to change the screen and even if the green line comes again after some time, I have to keep on changing it. Samsung, i excepted better service.
