Key Takeaways
1. The Galaxy Z Fold7 is priced at $1,899 and was featured in a YouTube video where it was taken apart and burned to test materials.
2. The primary goal of the video was to verify the presence of titanium in the device using a $20,000 XRF spectrometer.
3. The internal backplate exhibited oxidation patterns when exposed to flame, while the mesh produced sparks.
4. The Z Fold7 has limited cooling solutions, with concerns about an air gap between the mid-frame and processor covering.
5. The video raised questions about the repairability of the Z Fold7 and speculated on future Samsung devices, like the tri-fold.
The Galaxy Z Fold7 is priced at $1,899 on Amazon as of September 2, 2025. However, that didn’t stop Zach Nelson from kicking off his newest YouTube video with the innovative foldable Samsung flagship taken apart and set ablaze.
Exploring the Interior
To be fair to the host of JerryRigEverything, his primary aim involved using a ~$20,000 XRF spectrometer to verify that the Z Fold7 indeed features titanium inside. Samsung claims this material is used in an internal backplate to enhance structural strength, along with a mesh that adds flexibility.
During his investigation, Nelson discovered that the backplate showed a distinct, almost rainbow-like pattern from oxidation when exposed to a flame, while the mesh burst into a small cloud of white sparks.
Critiques on Cooling
In his review, Nelson pointed out some shortcomings within the Z Fold7, especially the limited cooling solutions. Although the new flagship had sufficient thermal paste to create a little smiley face, he still expressed concerns about an air gap found between the anodized aluminum mid-frame and the graphite covering the processor.
Additionally, the vlogger demonstrated the ability to remove the main 8-inch Dynamic LTPO AMOLED 2X display in one piece while it was still powered on; however, attempting to separate some layers might result in failure.
Future of Repairability
It will be fascinating to see if the first Samsung tri-fold will offer similar possibilities for repair in its anticipated launch.
