Before the new model goes offline, some engineering machines will be produced for testing. See if the version and hardware meet the standards. The specific scope of use is not allowed to circulate within the company because it is still a semi-finished product. At present, many unscrupulous traders leak construction machinery to the market and sell it as genuine products, so consumers should pay attention to it when buying.

Of course, many people say that they have engineering machines, which are used for counterfeiting. It's best to be careful not to buy goods with obviously low prices. Transaction security is the most important.

What is an engineering mobile phone?

As a high-tech product, mobile phones need to go through pre-research, planning, R&D, design and comprehensive testing before a model is put on the market. In this whole improvement process, some models of finished products and semi-finished products manufactured by manufacturers can be collectively called "engineering machines". Compared with the mobile phones that were officially listed later, engineering machines are all "not for sale".

What does mobile phone engineering machine mean? Main explanation

Hello, are you talking about the mobile phone engineering model? That depends on what platform your mobile phone is. If it is a cottage, you can know which motherboard and platform it is by obtaining MTK detection instructions and entering version instructions. In order to make good use of MTK Smart King, when you get the user's mobile phone, you need to identify whether the mobile phone is a MTK platform mobile phone through the manual. As long as you meet one of the following instructions, you can recognize that the mobile phone is an MTK platform.

MTK restores the original password: 1 122.

What's the difference between engineering machine, testing machine and ordinary mobile phone?

Construction machinery, research and development model. It is usually a model that has just been manufactured and has not been tested and corrected. The testing machine is similar to the engineering machine, but it is mainly used for internal testing. For example, machines distributed to employees or users are asked to test, and then bugs in the test are reported so that manufacturers can correct them. Ordinary machine is a machine that has been officially listed after BUG correction in the first two stages. Ordinary computers are much better in quality and software performance than the first two.

What does the mobile phone term engineering machine mean?

Construction machinery is like an experiment. Make it first, then gradually improve it, see what is not perfect, and then launch a mobile phone.

What is a millet engineering machine?

The so-called mobile phone engineering machine is the machine that tests the new model before it goes offline. Mainly to test whether the version and hardware meet the standards. Mainly used in companies and some mobile phone enthusiasts or users with fever, generally not allowed to circulate, mainly because it is still a semi-finished product. However, Xiaomi broke the routine, because Xiaomi's slogan was to build mobile phones for enthusiasts, so Xiaomi sold engineering machines to users for testing from the first generation, and then rectified them according to the feedback of engineering machine users, but mainly the software rectification, and the hardware remained basically unchanged as long as there were no major problems, mainly to optimize the program. Now on the occasion of the release of Xiaomi 2, Xiaomi 2 is mainly for testing. General engineering opportunities are cheaper than regular machines. But Xiaomi is still authentic. If you buy an engineering machine, you can change it into a formal machine after sending it out, and you don't need to add money. However, the engineering machines of Xiaomi 1 are all numbered, so many people don't change the official machines after buying the engineering machines, mainly as souvenirs. The quality of the engineering machine is not much different from that of the regular machine, and there should be no problem with the hardware, mainly testing. Just like the joint debugging in engineering, can you say that the quality of the project is not good during the joint debugging? Typing is not easy. I hope the landlord can adopt it. Your adoption is the motivation for my answer.
