JerryRigEverything abuses Redmi K20 Pro / Mi 9T Pro, but he resists

If smartphones could go to court to defend themselves against abuse and harassment, probably Zack Nelson aka JerryRigEverything would have a life sentence ... several times. There are hundreds of devices that youtuber torture and yesterday it was the turn of Redmi K20 Pro, which we know in Europe as Mi 9T Pro. The differences between the two are not there, so we can say that the test is valid for two devices, and therefore two points in favor of Xiaomi which also in this case has done an excellent job regarding the resistance factor. If you want to see youtuber in action, skip the video at the minute 2: 20.

JerryRigEverything abuses Redmi K20 Pro / Mi 9T Pro, but he resists

The video starts with a comparison that may seem a bit strange and that the well-known teller carries on for all its duration: the Redmi smartphone comes from compared to the Samsung Galaxy Note 10. Now, if on the one hand this comparison is absurd, on the other hand we must recognize a merit to the Xiaomi sub-brand that has managed to do an excellent job and even be compared to a device of that level. This does not mean that it is the best, but side by side with two smartphones, one for about € 800 and the other for about € 35, is symptomatic of quality.

Moving on to the more interesting part Zack starts as usual with the scratch test of the display with tips of different hardness and we can see how the Redmi K20 Pro stands up to the 6 level; from here on the scratches on the type glass begin to be evident SUPER Amoled Gorilla Glass 5.

But what everyone wants to know, more than the resistance of the display, is the resistance of the photographic sector which is composed of three rear sensors and a front one that comes out through the pop-up mechanism. Well, Redmi has done a remarkable job considering that as far as the three cameras behind the cutter are concerned, it can't even scratch the glass at all. The same happens with the front camera of which the youtuber is literally in love: despite it is covered with a layer of plastic (and not metal like other parts of the smartphone), it resists very well and a good job makes the glass that protects the sensor from 20 megapixel.

This is also super resistant to the cutter of the torturer e does not scratch in contact with the blade in the slightest. At the resistance level of the mechanism that lets the camera out, the youtuber congratulates because after several beating it open does not break. In addition to the barrel, our Jerry "caresses" this time the smartphone blocking the pop-up head at the opening, clearly wanting to see if you can see some jam or some crash (the one I personally expected): but nothing, even here the device passes the exam.

The back of the last one released by the Casa Redmi is also very resistant and does not scratch the passage of the cutter. This time, Zack does not opt ​​for bits of different hardness but only works with the cutter. therefore red psychedelic back and rear cameras from 48 + 12 + 8 megapixels don't flinch when the blade passes and also for them the test is passed.

Another point that is very interesting to see is the resistance of the front glass in the lower part, where the fingerprint reader is placed: the difference that the youtuber makes is, as mentioned, with the Samsung Galaxy Note 10 which mounts an ultrasonic biometric sensor unlike an optical type carried by the K20 Pro. Despite the difference both are excellent but Zack feels to compliment Redmi for the work he has done since despite the scratches with an 7 level tip the release works without any problem.

If you were undecided about buying or not Redmi K20 Pro is Mi 9T Pro if you prefer, know that at the level of resistance it does not (perhaps even) and be on the safe side.
