Galaxy Z Flip 8 Screen Crease and Touch Problems
A slight crease in the middle of a foldable screen is a natural result of the design and is not a fault by itself. On the Galaxy Z Flip 8, service is needed if touch fails in one area, the factory film is lifting or a green-pink line appears. Do not peel the film yourself; Samsung's authorized service can replace it.

Short answer TL;DR
A slight crease is normal; it forms at the hinge and does not affect the image. If touch fails in one area, the film lifts or a line appears, do not peel the film and contact service. First clean the screen, remove thick cases, update the software and run the Samsung Members touch test.

01 — Step-by-step fix
How do you fix it? Step by step
-
Step 1/7
Identify the type of crease
Turn the screen off and look at the hinge area. A thin, even line in the middle is the normal structure of a foldable panel. If a green or pink line, a black spot or loss of touch appears along with the crease, it is a hardware fault, not a cosmetic issue.
-
Step 2/7
Clean the screen and hinge
Wipe the screen with a microfiber cloth while it is closed. Dust and sand around the hinge press on the panel when it folds and can cause touch errors. Do not use compressed air, and never spray liquid directly on the screen.
-
Step 3/7
Remove thick cases and screen protectors
Thick cases that squeeze the hinge and third-party protectors can affect the folding angle and touch. Remove the case and test the screen directly. You may need to remove any protector applied after purchase, but never the factory film.
-
Step 4/7
Run the touch test
In Samsung Members open Support > Diagnostics > Touch screen test. Drag your finger across the whole screen; if a strip does not respond, that area is faulty. Keep the test result for the service visit.
-
Step 5/7
Update the software and restart
Install the latest One UI build from Settings > Software update, then restart the phone. Temporary touch driver bugs sometimes clear after an update or restart.
-
Step 6/7
Do not try to fix a lifted film yourself
If the factory film is lifting at an edge, has dust underneath or shows bubbles, do not pull it. The wrong handling can scratch the panel or damage the protective layer. An authorized service center can replace the film under proper conditions.
Do not remove the screen film or panel yourself; damaging the protective layer of a foldable panel can void the warranty.
-
Step 7/7
Contact service for lines, spots or touch loss
If a permanent green or pink line, an ink-like black spot or touch loss appears, open a service request through Samsung support. Report any impact or liquid exposure; the evaluation depends on it.

Frequently asked questions
Is a crease on a foldable screen normal?
Yes. On foldables such as the Galaxy Z Flip 8, a slight crease at the hinge is part of the panel design. It may become slightly more visible over time, but a line, spot or touch loss means service is needed.
Can I remove the factory screen film?
No, do not remove it yourself. The factory film is part of the panel's protective layer; incorrect removal can permanently damage the screen. If it lifts, an authorized service center must replace it.
Does cold weather affect touch?
In extreme cold the foldable panel and film become stiffer and touch response may slow temporarily. Do not fold or force the phone until it reaches room temperature.
What should I do if the touch test fails?
Take a screenshot of the test result and open a service request through Samsung support. Unauthorized repairs can affect the warranty; do not open the phone yourself.
