The Galaxy Z Flip 4 got durability tested
The first test is the scratch test, as per usual. There are two displays on this phone, the main foldable one, and the cover display. The latter is the first in line, and it got scratched up at a level 6, which is to be expected. That panel is protected by the Gorilla Glass Victus+. The main display is an entirely different story. Zack managed to scratch it with a level 2 pick, while at a level 3 the scratches were deeper. So yes, your fingernails can damage it, if you’re not careful. You’ll have to press down really hard, though. Samsung is using ultra thin glass (UTG) here, but there’s obviously a plastic layer on top of it, which you should not remove. Samsung used metal for the frame of this phone, which is something Zack proves here. The volume up and down buttons are also made out of metal, though that volume rocker is removable.
Dust test is also quite interesting to watch
Zack also decided to bury the phone with dust, to test it out. He definitely went overboard, though, as if the phone was buried in dust. The phone actually did well in this test, despite the fact Samsung doesn’t guarantee it can handle dust. We’ve also seen the phone’s display exposed to open flame, as we do in every JerryRigEverything video. These tests are not exactly especially useful, but there you go. The front screen is covered by plastic, so you know what happens in that case. The rear display had a more normal reaction, though. The test that is usually the most interesting one is the bend test. That is also the last test you’ll see in this video. Needless to say, foldable phones should be more prone to breaking than regular phones. That’s not always the case, though. When Zack applied pressure from the back, a rather strange noise occurred, but the phone didn’t break. It also remained functional, but couldn’t close properly. The Galaxy Z Flip 4 did worse than its predecessor, though, as the predecessor didn’t bend thus far, nor did it pop.
