Why Your Foldable Will Break
40sChallenges Samsung's durability claim by questioning the real-world fold count and environmental factors.
▶ Play ClipAI Summary
The video documents the unexpected failure of a Samsung Galaxy Z-Fold7 after only a few thousand folds, well below its rated 500,000-fold lifespan. The creator investigates potential causes, ruling out dust and water resistance, and hypothesizes that extreme cold temperatures (20°F / -7°C) may have made the hinge mechanism brittle. The video concludes with the creator considering alternative phones.

Samsung's fold rating
Samsung rates the Z-Fold7 for 500,000 folds, which at 80-100 folds per day would take years, but the device broke after only a few thousand folds.
[00:15]
Dust and water resistance ruled out
The IP48 rating means the phone is watertight and resistant to dust particles down to 1mm, so dust is unlikely to be the cause of the failure.
[00:28]
Cold weather hypothesis
The creator used the phone for several days in 20°F (-7°C) weather, which may have made the hinge mechanism brittle, as this temperature is outside Samsung's likely testing conditions.

Considering alternatives
The creator is now considering switching to a different phone model, implying a loss of confidence in the Z-Fold7's durability.
The video suggests that extreme cold may have contributed to the premature failure of the Galaxy Z-Fold7, despite its official durability ratings. The creator is now looking for a more reliable alternative.

[00:02] why did it break? Samsung says these are rated for 500,000 folds, which if you do the math on that, 500,000 divided by, say, 80 to 100 folds a day, you're Surely, there's not that much variance
[00:15] after a couple thousand folds. So, the other thing to consider is maybe the dust and water resistance rating. IP48 means it should be pretty watertight. That's not the problem. And the four means it's good for dust down to 1 mm.
[00:28] don't think it was the dust, either. So, here's what I think it was. I was for several days in a row. I was using my phone and unfolding and folding it temperature outside was 20° F. That's about -7° C.
[00:42] it would be within normal use, but it's very likely not the temperature Samsung used when they were testing and rating this for 500,000 folds. But, something get really brittle. This was on an outside pocket in my coat, so it wasn't
[00:56] temperature. What phone should I switch to now?
