Well, I have found the Launch X431 PRO 3S+ to be very useful for its features. It has some cool and mind-blowing features that are hard to find in other scanners. Here is what I want to say about the all-new Launch X431 PRO 3S+.

Speaking of the hardware, it is very well suited, fast, easy to use, and very light. It is quite smooth and perfectly structured to use. 

Because it has a huge compact package, the battery capacity had to be better. Respectively, it has a 6600 mAh battery.

The hand product was not that heavy. It is quite compatible with the hands and easy to carry. When designing a small host unit, a screen display could be an issue, but the designers have come up with an equally clear display that can be seen in broad daylight as well as in the workshop.

One amazing factor about this product is its Bluetooth capability. You can hear its Bluetooth service from 5 meters. Where other products get hung while using Bluetooth this product has a smooth connection as well as smooth tablet function on other features.

Another eye-catching feature of Launch X431 PRO 3S+ is its complete system analysis. The X431 Pro 3 has a wide and comprehensive system coverage, which includes all of the most popular automobile brands and models. Obviously, the devil is in the details when it comes to special functions, coding, and so on.

Well, I think the most appreciated thing that the Launch X431 PRO 3S+ has is the Graphic Live Data Stream. This is one of the features that almost all scanners should have because it makes the work of a mechanic very easy to do.

Lastly, one of the advantages you get with  Launch X431 PRO 3S+ is it can store the data after every diagnosis. The business details can be set to appear in the header of the diagnostic report and can be generated by the technician whenever they want it.. 


  • Precise test results
  • Delivers information thoroughly 
  • Provides Golo users with access to remote diagnosis
  • A fault code reader and clearer
  • An extensive diagnostic report can be printed from it.
  • Connects automobiles to repair shops


  • The cost of the device is very high.

Why does the shell not see brands?

In the case of the shell X431, Pro3S 3.10.020, for example, stamps were copied in the wrong direction:

  • The launch / X431Pro3S / 968 Automobile Diagnosis and Repair
  • There must be folders for trademarks such as RENAULT, AUDI, and BMW in the VEHICLES folder.
  • This folder 968 contains the serial number of your device–  folder 968.
  • A folder can launch a revolution in the filesystem of your tablet or smartphone.

Why does the computer not see when connecting to the cnlaunch folder?

A file manager such as Total Commander or any other can be used to copy the cnlaunch folder to an SD card, which can then be used on another computer.

Use any file manager, such as Total Commander, to make a copy of the folder that can be launched directly from the device, and it will use the new folder name, making a new folder visible on your computer.

If you use any archiver, such as RAR, to add a cnlaunch folder to an archive, the archive will be readily available for use on a computer.

This is the safest and most dependable approach. It’s possible to work with the root file system of your Android device without restrictions if you install the ADB plug-in for Commander of Total All Android.
