Fold 4 Official screen protector - PSA

Thin hairline marks will appear on the protector when first applied.

The lines do go away.  Let it dry and then rub it with a microfiber cloth.

Hi @iPhone_McGee ,

I'm sorry to hear about that. Can you please let me know when and where did you get your phone from? Was the screen protector like that since day 1?

Yes I've had similar problems like this before with not just Samsungprotectors. But leaving it to cure, they seem to dissappear
Wonder if it's to do with manufacturers tooling or something like that

Same issue here, and the one previous to that did also. I did exactly like the video and same result.

Just a update lines have fully gone took 2 days Samsung really need to explain this somewhere
