iPhone X

iphone X has issues with its graphics card and touch screen. It does not always present immediately - sometimes months after using normally. Apple hides in its 12 month warranty. Despite it being a technical issue that they know about, and that presents specifically with the X, you have no control over whether your phone will have these issues, or when. But if it gives the problem you will need to pay R6-7k to have it fixed. Choose wisely.
