The latest phone that Zack from YouTube channel JerryRigEverything has put through his now traditional durability test is the OnePlus Open. The first foldable smartphone from OnePlus has normal glass on the cover display on the top. And like any other glass, it scratches normally from level 6 on the Mohs hardness scale. Deeper grooves appear from level 7 onwards. The main display is similar to other foldable panels. It is covered by a plastic protective film, which shows scratch marks from level 2 onwards and suffers deeper damage from level 3 onwards.
The side frame of the OnePlus Open is made of aluminum and appears to be reasonably dustproof. The outer display lasts about 25 seconds when exposed to an open flame. After that, the pixels turn white – fairly normal behavior for OLED screens. The plastic screen protector on the main display, however, burns within about five seconds.
Finally, there is the bending test, which the OnePlus Open survives when folded and bend from both directions. In addition, it also withstands bends when opened against the normal folding direction. After that it doesn’t lock into place quite as cleanly as before, but it still remains 100% functional.
OnePlus smartphones haven’t had the best track record in these bending tests recently. So it’s great to see that a potentially very vulnerable device actually ranks among the most resilient phones in such tests. This makes the OnePlus Open even more of a purchase recommendation.
