Samsung rarely opens the doors to its production lines, but the Galaxy Z TriFold is such a unique device that it was worth making an exception. The company showed what the process of folding and testing the first triple-folding smartphone looks like, which will be available for sale in the first quarter of 2026. And it must be admitted — what the TriFold goes through before it gets into the box is impressive.
From Two Hinges to One Screen. The Assembly Process
Production starts with the automatic assembly of two Armor FlexHinge hinges that are designed to provide stability during the triple folding of the structure. Following this, the steps are:
bonding the display,
pressing the main screen, which compresses the entire structure to make it thinner and more durable,
pressing the rear casing, which encloses everything into its final form.
Everything looks like part of a factory for assembling the laptops of the future — except that the end product is a smartphone.
Tests That Justify the Price of Over $3,000
Once the device is assembled, the real marathon of tests begins. Samsung lists them in one breath, but the list shows how complex this model is. On the TriFold, the following are performed:
3D surface scanning — checks the quality of components and micro deviations,
hinge angle test,
fast computed tomography (CT) analyzing the interior of the device,
camera sharpness test,
test of 200,000 folds,
simulations of real-world usage conditions, meaning the impact of temperatures, battery operation, and changing pressure forces on the screen,
water resistance test.
The TriFold receives IP48, meaning resistance to immersion in fresh water up to 1.5 m for 30 minutes. However, Samsung emphasizes that it is not a device for the beach or pool — it's more of an emergency safeguard.
Smartphone from the future that must prove its durability
All these processes are not surprising, considering the expected price of around 3000 dollars. This device aspires to be the most advanced mobile format on the market, so the tests must be equally advanced. One must admit — looking at how much effort Samsung is putting into the TriFold, it's hard not to get the impression that the company wants to create something more than just another foldable smartphone. It’s a showcase of technological strength and an introduction to a completely new category of devices.
Is this your next phone?
The authors of the material ask: will this be your next smartphone? Looking at what’s happening behind the scenes of production… many people might answer, “probably yes.” TriFold is a vision of the mobile future encapsulated in one device — now additionally complemented by an exceptionally rigorous testing process.
