I was having some problems with my iPhone battery, so I took to a store and they had it replaced. When I got home, I’ve noticed a dar/purple spot on the screen. When I came back to the store they told me that the damaged battery could have leaked into the screen and that’s why I have this spot. Is this really possible?
Felipe Sales,without seeing what you see and" I’ve noticed a dar/purple spot on the screen." sounds like a broken LCD. Take it back to whomever fixed it and let them know that this is not battery leakage in the LCD (absolutely bogus). Sounds more like a bad repair to me.
