I purchased Galaxy Note 9 (International version) while at USA in August 2019 9via Amazon). I am currently located in India. Recently after some security patch update by Samsung, my device screen is showing some problem. The screen color turns yellowish/greenish with horizontal lines, particularly in medium to high brightness. I visited Samsung service center at Hyderabad, India. They mentioned that the issue is due to software update with wi-fi connection, and may be because of unstable wi-fi connection, the screen got damaged. They also mentioned that I have to change the screen which will cost around 17k Indian currency, and the even after the display change there won't be any warranty. This is so annoying. Why should I pay that much money to change the display when it is Samsung's faulty software update that damaged the screen. It is better to switch to some other brand other this Samsung scam.
Yeah, I have the same issue on my s10, and their customer service is very poor in India. Its better buying iPhone, they charge slightly more that samsung phones but service is 1000 times better
