My iphone X was MINT until 2 days before the 11 launch. Then the day before, as I was about to fly to london I dropped my laptop on it, shattering the screen and the back. Screen replacement was ok, until the update to ios13, when suddenly I couldnt flick up anymore... So suddenly my iphone X dropped in value from £450 to £50, I spend $120 on a front screen replacement, then I was in london where the 11 cost a load more, and had to buy one. So I quite literally had the worst possible outcome.
Salty as I may be, I honestly, apart from the night mode on the camera (which is actually very good) I see very little difference from the X.
