Been using my sigelei Zmax for a while now and the screen was getting quite scratched. I began running my finger nail across them only to make it worse. Yes I know Mom always said "Don't pick at it". I assumed this was the way it was however my nail broke through at some point to another layer. I was so surprised to find glass under a plastic film! Removed it all and a perfect clear display lay under it. Is this for shipping protection? Not sure. So start picking at it!
