I bought an iPhone X from USA. After I returned to my country, Turkey, i started to use the phone, it was working very smooth for 2 hours. Then I encountered a ??hardware?? problem after 2 hours of using, which does not allow me to use the phone (unresponsive screen problem). I called the Apple Store in Turkey and they said your phone model (A1865) is not under warranty in Turkey. However, I checked apple.com with device’s serial number, it says the phone is under warranty internationally for 1 year, including my country. They said I had to take the phone back to USA in order to get service. It is reaaally annoying.
