Coincidentally, those dark spots appears in the area where my hand usually touch the phone. I live in a tropical country and this probably happens because my sweat somehow harm the aluminium frame. Anyone experiencing this issue? And does anyone knows how to make these dark spots gone?
Something weird happening to my Xperia Z1's aluminium frame since 2 months ago. I begin to notice there are some dark spots or pitting on the bottom right of the aluminium frame. Now those dark spots are appearing even more. I tried using my fingers to feel those dark spots and it feels like when I'm scratching a corroded steel
