Under normal circumstances, mobile phone manufacturers will only announce the basic parameters of the product, but the models and specifications of many internal components are secretive. So, how can we see the detailed parameters of all the hardware inside the phone?
The simplest "hidden parameters" (can be downloaded in Cool An) is such an APP, after installing and running on the phone, it can list almost all the hardware and sensor data inside the phone, and click on the corresponding hardware to test its function and performance.
Taking the screen as an example, we can test the screen defect, the screen boundary, whether the screen is high color gamut, whether it is 10 deeper than the feature and brightness.
It should be noted that the test of "hidden parameters" is more subjective and requires us to make judgments based on naked eye observation, so the high color gamut, color depth and brightness tests are not necessarily accurate.
Similarly, we can also test the touch coverage area of the screen, support a few touches, sample rate and pressure touch, and if the phone accidentally falls and bumps, you are worried about the damage to the screen hardware and can troubleshoot through these tests.
Now many mobile phones are known as built-in dual speakers, in the "hidden parameters" can be a separate test of the double speakers, if the sound volume and sound quality emitted by the independent channel are different, it can show that the manufacturer did not choose the "symmetrical" stereoscopic double Yang, and there are some small family temperaments on the material.
In general, through the "hidden parameters" we can intuitively understand the detailed hardware data of the mobile phone, although it has limitations, such as the inability to read the detailed model of the camera sensor, but the data involved is already richer and more accurate in the same kind of APP. The addition of testing functions is also more practical, and it can also be used to troubleshoot mobile hardware and functional defects at any time.
In addition, benchmarking software such as AnTutu can also query the detailed parameters of the mobile phone, and even more accurate than the hidden parameters in the labeling of some information, which can be combined.
