Re: Need some help removing scratch from screen
Depending on the depth of the scratch, you may try either to patch it up or to wear down the vicinity of the scratch. If your nail snags on the scratch, then you may try painting clear nail polish* onto the scratch. Once you've covered the scratch, gently wipe off the excess liquid outside the scratch using a piece of cloth (not tissue paper or any other fabric with loose fibers), making sure that the liquid forms an "even" surface with the vicinity. Wait for it to dry, probably for 30 minutes. Repeat if necessary.
If you nail doesn't snag onto the scratch, apply some metal polish onto the vicinity of the scratch and then rub vigorously with a piece of cloth until the scratch disappears. Note that this process will reduce the oleophobic coating on your screen and make it more prone to future scratches.
*- Or any liquid that hardens into a clear solid material.
