Teardown from Samsung’s Galaxy Z Flip reveals that its hinges may not block as much dust as promised

Teardown of the newest foldable phone from Samsung, the Galaxy Z Flip, reveals that a ‘fiber shield’ may not be able to prevent dust particles from clogging its hinge despite promises

  • A breakdown of the Samsung Z Flip suggests that the hinge may be sensitive to dust
  • The video from iFixit on YouTube places the folding device against a bag of purple fabric
  • Results show that the dust has entered a ‘fiber shield’ and has reached the hinge
  • Samsung is launching its new hinge as an improvement on previous offers
  • Dust particles infamously felled displays from Samsung’s Galaxy Fold

Samsung promises a new hinge in its latest foldable phone, the Galaxy Z Flip, will offer more protection against dust particles, but a recent removal by i fix it suggests that it may still have some work to do.

In a video posted on YouTube, iFixit, a popular repair and research agency, puts the Galaxy Z Flip – released this month – to the test.

In particular, researchers use a bright purple substance (iFixit does not say exactly what the powder is made of, but it seems to be as fine as dust that you usually find in your home) to assess the durability of a new ‘fiber shield’ hinge of the Z Flip.

Although Samsung has said that its phone is not dust-proof, during the unveiling of this month the company has ensured that it promotes its fiber shielding, essentially a lot of small nylon rungs, as a new method to reduce the risk of catastrophic interference in the display of the phone, comparable to those who teased his first foldable scorn, the Galaxy Fold.

However, when faced with the purple dust from iFixit, it seems that the dust has still entered the hinge quite heavily.

In the first test of the company, he dropped a folded Z Flip into a bag full of dust. After having pulled it out, one can see that dust has entered the hinge and in a quantity large enough to prevent the device from fully opening.

After the hinge was removed from the phone, the iFixit video also shows that the dust appears to have bypassed the fiber screen and covered the mechanism.

However, the fiber shields themselves appear to be fairly dust-free.

Although the hinge was covered with dust, Samsung's fiber shield was relatively clean. This may indicate that they do little to actually collect dust before it reaches the hinge

In the video from iFixit, dust is clearly visible in and around the hinge, despite Samsung's promises that the fiber hinge would help prevent particles from reaching the mechanism

This is not the first sign that the newest foldable range from Samsung may fall short.

In another video posted by Zack Nelson, who runs a YouTube channel called JerrryRigEverything, the researcher finds many shortcomings in the visible ‘Ultra Thing Glass’ display of the Z Flip.

In addition to scratches much easier than real glass, underlying pixels in the device are easily pierced. The material also seems to burn much easier than real glass.

Samsung responded to Nelson’s video by saying that although the screen is actually glass, it has a protective layer on the outside that resembles that on the Galaxy Fold. His review also confirms the existence of that layer.

Although iFixit and Nelson teardowns do not necessarily mean that the Galaxy Z Flip is doomed to be scratched and jammed with dust, it raises some doubt about the durability and stability of foldable phones in general.

At the same time, it has been reported that Motorola’s recently released Razr revival, the company’s first phone with a folding screen, has problems peeling off the screen.

It is unclear how widespread the problem is or exactly what it has caused. Raymond Wong from Input paid attention to the problem for the first time this week and assumed it could be related to temperature shifts.
