okay, so here is my experience. I got my iphone from US through my cousin. The moment I opened my phone, viola terrible pink hue on right hand side, dust in camera lens. Boi, my all excitement went to gutter by looking at these problem. And worst part of is that, I live in India, so apple don't swap phones for fault's, they repair the part. I took my phone for the same problem, they replaced the display and camera setup. I started using the phone, but for some reason I wasn't able to enjoy my device, since It was serviced right after it was taken out of the box, no thrill whatsoever for a new device.
Then, after reading few post about display uniformity which can be seen in clock app, I found the same problem in my replaced display, I sent my phone again to the service centre and they changed the display. Now, to my surprise the 2nd display they have changed is worst than before, it has all that yellow tint terrible shift all n all display was a garbage.
Then, I went to the service centre again, told my journey about Iphone X experience and the guy was quite supportive. i stated him that this is m 3rd visit and my phone is going to the repair centre for 3rd time and still the issue persist about the display. he made me assured that he will get my phone replaced and after a week finally today I got my brand new replaced device. God, finally i can feel the rush for owning the new device no drama this time about the display. It isn't perfect but surely a keeper.
Guys, anyone who is facing a problem, I think you should try to get a good device, chaos is worth after all. I can tell this from my experience.
