I have protected my Surface 3 with the Microsoft tempered glass screen protector. It was quite stressing to put it on, but now I see what seems to be a small piece of dust. I am in doubt whether or not to remove the cover (just lift it a little bit) and try to remove the dust with sticky tape. I can only hope I don't make it worse. A Surface 3 is not the most expensive one, but still the screen protector costs about € 35,- as well! Any suggestions? Experience?
