Can you use a screen protector with your foldable phone?

Foldable phones utilize flexible layers rather than rigid glass to endure repeated folding. Consequently, internal screens typically feature built-in protectors. Adding unapproved layers or removing the original protector can damage the display. While outer screens require standard care, inner displays need specific handling. Both Samsung Galaxy foldables and the recently announced iPhone Duo incorporate these integrated protectors. Users must follow manufacturer guidelines for replacements to ensure the device's longevity and prevent permanent screen damage.
