I got my S9+ in April and due to bad luck, I managed to scratch up my screen before the screen protector I ordered came in the mail. The scratches were very shallow and ran down the sides of the screen because when I dropped it, it slide across the floor.
I put on my screen protector which adhered to the screen via a special liquid that hardened via UV light. It filled in all the scratches and made them invisible. Recently, I cracked the screen protector because it fell out on my pocket while driving and got wedged under the seat.
Before I apply my second screen protector, I was wondering if I could possibly get my phone serviced locally and have the shallow scratches fixed.
For a proper job - I think that you're going to need to get the screen replaced - If you're using Whitestone Dome it should be replaced under warranty I believe - So unless you have the Carrier insurance - Or you don't mind spending a few hundred dollars - You may just want to replace the screen protector with the same brand...
From the description of the Screen protector that they were using all - It sounds like Whitestone Dome glass which uses a liquid adhesive & it fills in scratches as well as prove a tempered glass screen protector - Don't know exactly what they want to do or how much they want to spend?
If you'd like to get those scratches repaired, you can contact your local Samsung Service Center (http://www.samsung.com/ca/support/servicelocation/) for assistance.
