This is the original screen. The phone has Never been opened in its life,never dropped or cracked screen etc. The blue mark in the top right corner has appeared today (it’s been very heavy rain here today) but it has not been submerged in water or anything,maybe the odd bit of rainfall landed on the screen a few times. I suspect water is/has gotten inside today and previously as the larger area at top right has been there for some time. Is this a common occurrence or is it a faulty screen?
