After 1 and a half years, the inner screen protector of my Z Fold 5 started to peel. So I went to Samsung Service Center at SM MOA and Festival Mall to buy a replacement. Unfortunately, both branches didn't have any stock left. The customer rep also told me that the stock screen protector is no longer adviseable once the crease starts to deepen. So with the help of youtube, I carefully removed the stock screen protector from the Fold and bought a new one. I went with the same brand I used with my Z Fold 2 - Ringke. I highly recommend this 3rd party screen protector. It is self-healing and adheres well to the Z Fold 5 screen.
Is there a rainbow line? I have searched this for the Z Flip 4 before. I found one YouTube video that got a rainbow line due to factory defect. Basically a line (vertical for the Z Flip) that is visible especially with a white background display.
Yes, there is one in the middle if you look for it. Just like Z Fold's crease, it'll just grow on you over time. With less than a thousand, you can buy another one or look for a better one. What matters most is ensuring the screen is never left unprotected.
