Samsung Galaxy Fold 4: Samsung Galaxy Z Fold 4 won't fully open

Fri, 30 Jan 2026 11:37:50 -0700

Recently, my Fold 4 stopped opening 100%. Now when using apps that require touch from the middle of the folded screen, it doesn't always register the touch. Is there any guides on how to fix this issue? I haven't even had this phone 2 years and it's a $2000 device. I've read a ton of complaints about this issue, but no real solutions to fix it other than take it to Samsung and have them repair, which they argue with some customers and won't repair it. Please help!

Samsung Galaxy Fold 4: Samsung Fold 4 not unfolding 100%. Adhesive/Film?

Sat, 05 Jul 2025 15:11:52 -0700

Recently, I noticed a film starting to lift on the hinge of my Samsung Fold 4. At first, I thought it was just the factory film that I’d forgotten to remove, but when I tried to peel it, I realized it wouldn’t come off. I only lifted a small section before pressing it back down. Immediately afterward, my phone stopped opening fully, and the issue has gradually worsened.

I don’t think the hinge is broken or dirty—I suspect the film has bunched up inside and is causing the problem. I’m considering using a 0.01mm iFixit blade to try and fix it myself, but I’d really appreciate any guidance.

If the blade alone isn’t enough and I want to handle the repair myself (since professional repair costs are so high), what tools or supplies should I buy to make this as easy and successful as possible? Any links to videos, recommended tools, or advice would be greatly appreciated.

Thank you for your help!

When opening my Z fold 4 it doesn't open flat. I cleaned it and made sure the cover is not in the way.

Samsung Galaxy Fold 4: Folding Screen -- Lines of Failing Pixels

Sat, 10 Feb 2024 10:57:53 -0700

Has anyone found what is causing the common issue of lines of pixels failing on the folding screen?

For example -- I am on my second Fold 4. The previous Fold 4 and this one has the same issue. A column of discolored pixels running the entire length of the folding screen's crease; and a row of bright white pixels at the very top of the right side of folding screen (running from crease, through camera area, to right side bezel).

Sidenote: I am severely disappointed in Samsung's warranty. A reason for choosing this phone was the relief of it having a warranty. If there is even a scuff on the paint -- they deny coverage. It is borderline criminal. These devices are carried with us all day, every day -- a scuff/scratch/scrape should be normal wear. If my car gets a scratch, the manufacturer does not deny warranty.
