I've just bought a second hand XZ2 Tablet. And it has some slight scratching on the screen. I will be putting a tempered screen protector on it and a flip case. I did last have a z1 compact and a z ultra. And they had a anti shatter film. I presume the XZ2 Tablet has the same. Is there any thing anyone can advise to kind of rub over the top to sort of fill the scratches? Obviously which doesn't hinder the screen usage.
Thanks
