I had it replaced once, perhaps 15 months after purchasing. The problem was not with the screen, but the screen protector was separating down the seam. Possibly due to my profession in the medical field, which occasionally sees me and my phone exposed to high intensity UV light. Apparently this shrinks the material. Modern phones aren’t something you can so easily work on yourself. I had it replaced by an authorized repair shop in my area. Apparently they had a recall on either the whole model or my production run, because they had a one time replacement deal for $250. This got me a new internal screen, battery, and possibly hinge?
