I don’t know WHY Samsung have to use such aggressive adhesive for the advertising stickers on their notebooks.
This stupid sticker near the keyboard peeled off, but it was designed in such a way that the gum stayed stuck to the notebook instead of the sticker!
I thought I would rub it off with windowlene, but NO CHANCE as it would have taken me all day.
In the end I used a clothes lint remover, on of those sticky ones with peel-off sheets and after using about 4 sheets to literally PULL off the adhesive it was all 100% gone.
I expect sellotape might have worked, but forget using liquids to clean this off.
