iPhone X touch screen is not working
I ordered an iPhone X on 27th October 2017 from apple store to an US address (TX)
My Mother has got the phone on 24th November 2017 from a courier service and she sent it to Sri Lanka.
I got the phone on 30th Nov. and it worked really good.
Since yesterday (13th Dec) the touch screen is not working. I have to tap many times to get a single tap. Even I can't shutdown the phone.
I did the hard re-set, but couldn't work. I searched on web and I found many people have same problem.
In Sri Lanka we have Apple authorized dealers. I asked them and they said still they are not selling iPhone X and they can not replace.
Is anything can do for this, because I have spent 999$ and phone is not working.
Is apple site is responsible to replace a new one or repair it? because I directly paid the apple site.
If I send it to USA, Can I get a replacement?
If yes, from where?
Please advice me.
iPhone X, iOS 11.2
