The OnePlus Open, the company’s first foldable smartphone, is the most recent device to undergo Zack from the YouTube channel JerryRigEverything’s customary durability testing.
Naturally, the cover display is made of glass, which scratches at a level 6 Mohs hardness scale (level 6 with deeper grooves at a level 7). Like all other foldable displays, the interior screen is protected by a plastic covering that scratches at level 2 and develops deeper grooves at level 3.
It is confirmed that the phone is composed of aluminum on its sides, and it appears to be fairly dust-proof. When the outer display comes into contact with an open flame, it takes about 25 seconds for the pixels to turn white, which is pretty standard behavior for OLED screens. However, the plastic screen protector on the inner panel burns in about five seconds.
And lastly, the bend test: when the phone is folded, it can withstand being bent in either direction. Furthermore, when it’s open, it can withstand being bent in the wrong direction. It doesn’t quite click back into place the way it used to after that, but it’s still fully functional.
It’s encouraging to see that OnePlus’s most resilient device—which many would have thought to be its most susceptible to these bend tests—is actually the most resilient given the company’s recent poor performance in these tests. Reality can sometimes take you by surprise and disappoint you.
