Can I get back the previous one after uninstalling the Huawei mobile phone light encounter test serv

Yes, because the one you use to log in is Huawei.

So basically, if you don't change Huawei, you won't change it, don't worry, this can still be recovered. Below is an extended resource on testing.

A test is a measurement that is experimental in nature, i.e. a combination of measurement and experimentation. And the test means is instrumentation. Because test and measurement are closely related, there is often no strict distinction between test and measurement in practice.

The basic task of the test is to obtain useful information, through the use of special instruments and equipment, the design of reasonable experimental methods, and the necessary signal analysis and data processing, so as to obtain information related to the measured object. The final result of the test is that the displayed information is entered into the information processing library and controlled. [1]

a. Measurement, inspection, test and inspection.

b. Quizzes and examinations.

c. Conduct professional tests and psychological tests: summarize and analyze psychological phenomena and laws through the compilation of scales and software to help people live and work better.

d. Marketing promotion.

The so-called "test" refers to "free tasting activities for customers" or "promotional activities such as free drinks, giveaways, trials, etc."

e. In medical clinical activities, "test" refers to the examination method of a certain hormone or physiological activity, which is an indicator to judge whether it is healthy or not.

It's definitely possible, what you used to log in before, you can use it now again, and the information in that login is still there.

No, my uninstall, and when I come back, it's not the same as before, and I'm going to play again
