The very appearance of Motorola Razr 40 Ultra has already set a new bar for competitive “flips”. But the vulnerabilities of the cases and internal displays of foldable smartphones remain almost the biggest problems of such devices. Despite the fact that such gadgets are no longer new, such problems remain. Zack Nelson (JerryRigEverything) checked what conclusions the Razr 40 Ultra developers made during this time.

From a more realistic portion of Mr. Nelson’s testing video, you can see that the Razr 40 Ultra still uses traditional case materials and screen protectors. That is, the aluminum frame can be scratched, small damages will appear on the outer glass over time, and the internal display is still protected only by plastic and a special film, which the manufacturer says must be left. In other words: the internal display can stil be damaged even by pressing on it with a fingernail.

Also, the Razr 40 Ultra still does not provide the same protection against water and dust as monoblock flagship smartphones. However, the case is relatively able to withstand a lot of dust. On the other hand, we don’t know how the ingress of small particles into the hinge mechanism itself will manifest itself over time. Therefore, most likely, such a smartphone should still be kept away from sand and similar demonstrated situations.

Fortunately, Zack did not manage to twist the smartphone in an unnatural way. The hinge resists pressure from the reverse side quite well, and the internal display is not injured.

Unfortunately, there was a gap under the external display. By pressing his finger on it, Zack managed to severely damage the glass. Of course, it is not at all a fact that such a situation can happen in normal usage scenarios, but the very fact of a rather large void in the body of such a device is already surprising.

Such destructive tests are still hardly representative of real use, but looking at the limits of the possibilities of modern technological developments is as interesting as before. Last year, Samsung Galaxy Flip4 also more or less coped with such “testing”. Its successor will officially appear this week and it is unlikely that Mr. Nelson will refrain from testing the new model of such a Motorola competitor.
