I agree about brand value , last year j7 15 still selling in high price. people that bought j7 last year can trade in their phone for higher value even now. You can’t do that with Chinese phone like Xiaomi and Lenovo. price drop and making you think. Is that all my phone worth. if your phone get frequent update and last long of course it will have high resale Plus samsung and Apple service centre is very good with customer. you know how many Chinese sets user still waiting for their phone to be changed to new one ?
