The OnePlus Open, a $1,699 foldable device was durability tested by Zack Nelson from JerryRigEverything. For context, or OnePlus’s track records in his tests, the OnePlus 11‘s back glass was shattered and the OnePlus 10 Pro was cracked in half. The OnePlus Open is subject to a million folds, a feat proclaimed by the company and demonstrated in a controlled environment.
The durability testing of the OnePlus Open begins with a scrutiny of the surface or the external elements.
In the scratch test, the Ceramic Guard glass (used on the cover screen) only suffers from slight scratches when scratched with a level 7 element on the Mohs scale of hardness. This is not a big deal, and it keeps parity with most other flagships in the market. Not to mention, with the aluminum side frame and the glass front and back, the phone appears to be sturdy while closed.
The soft inner screen can suffer from visible marks just from nails: be aware
However, for a foldable, the story starts when you unfold the foldable. Opening up the phone exposes the soft plastic display. Pressing a little hard on the inner display with nails leads to visible marks on it.
Notably, OnePlus says the phone has a layer of ultra-thin glass on the inner display panel. However, the whole display assembly includes additional layers such as the one for touch response. On top of it, is a soft plastic layer, always, for every foldable launched to this date.
Coming to ingress protection, the OnePlus Open is IPX4, meaning it’s not officially dust-resistant. The ‘4’ rating for water splash protection, is inferior in comparison to Samsung’s Galaxy Z Fold 5 or Google Pixel Fold’s ‘8’ or submersion rating. Speaking of dust, the phone does not have any official resistance rating against it.
The reviewer exposes the hinge to a plethora of dust and even larger granular particles. But surprisingly, the hinge appears to work just fine after the torture.
Opening up the OnePlus Open unveils the Open’s resilience against Nelson’s capabilities
After surviving the scratches and dust, the reviewer bends the phone (to the maximum of his capabilities) in both the closed and opened states to ensure that you won’t accidentally damage the phone while keeping it between you and the sofa.
When being folded in the wrong direction, the phone bends a bit but locks out and doesn’t snap in half. The OnePlus Open survives the bent test. It remains fully functional and passes JerryRigEveruthing’s extreme durability test.
