I have noticed these white spots starting to accumulate on my Note 10.1 screen. I tried cleaning it with a microfiber cloth but the spots seem to be underneath the glass. At first, there was this spot in the centre but now, I think new spots are starting to appear. Should I be worried? Any help would be appreciated.
