In the video, he scratches the display, frame, and camera areas of the Z Fold8 with a screwdriver and a knife. He also performs a test by applying a lighter flame directly to the screen.

Does Not Break Even When Bent Backwards... "Truly Amazing"

JerryRigEverything also tested bending the device in the opposite direction while it was unfolded. He applied so much force that his hands trembled as he repeatedly attempted to bend the device backwards. However, the product did not break, and the internal display continued to function normally.


JerryRigEverything commented, "It's truly amazing," adding, "I don't know if Samsung used material with Thanos-level durability when making this foldable phone, but the new Z Fold8 is yet another impressive survivor."


As of the 11th, this video has recorded 1.17 million views.

The domestic YouTube channel "Gunggeumhagi" also released a video confirming the durability of the Z Fold8 on the 5th. The video shows the screen being scratched with sharp tools such as an awl and tests for water resistance by submerging the device in water.


Gunggeumhagi also performed a test by applying force in the opposite direction of the fold after unfolding the device, but no significant damage occurred. Gunggeumhagi remarked, "This isn't what I expected to see, so it was a bit surprising," and added, "I thought there would certainly be a weak spot, so I checked every part, but to my amazement, nothing happened at all."


Samsung Electronics applied the 'Flex Titanium' technology to the display of the Z Fold8 for the first time, aiming to enhance durability and flexibility. According to the company, the dual-structure titanium increases rigidity about 20 times compared to conventional polymer film, while the thickness is compressed to about one-third that of a human hair.

Pre-Sales Reach 1.44 Million Units... Attracting Young Female Consumers

The Galaxy Z8 series is achieving results that surpass the previous model. According to the global market research firm Counterpoint Research, global pre-sales of the Galaxy Z8 series increased by more than 30% compared to the previous Z7 series.


Domestic pre-sales reached 1.44 million units, up 39% from the previous model, and more than 20% growth was recorded in Europe as well. Interest is also high in Japan. On the 10th, on Japan's price comparison site Kakaku.com, the Z Fold8 ranked 18th in popularity among 1,182 registered smartphone models.



The so-called "passport design," with reduced weight and thickness, shortened vertical length, and wider horizontal width, especially captured the attention of younger consumers and women. Until now, there was a strong perception that the Fold was a product mainly for middle-aged men due to its high price and large, heavy profile, but these design changes are believed to have broadened its consumer base. According to Samsung Electronics, more than half of the Galaxy Z8 series buyers during the pre-sale period were in their teens to thirties. Among women in their teens to thirties, Fold8 purchases more than doubled compared to the previous model.
