Many people have encountered the situation of broken screens, and some people have reflected that there will be a mobile phone signal and poor network speed after replacing the mobile phone screen. Is this the signal poor caused by the problem of the screen after the screen change, or is the screen not installed? Will the screen change affect the wireless WiFi network speed? Oh, really? Many people are very annoyed, if there are these problems after the replacement of the screen, then the following will tell you about the reasons for the deterioration of WIFI and other signals.
There is a screen change experience: the phone into the water, black screen. After consulting the repair shop of the mobile phone, the boss said that the screen was broken, and the screen should be replaced, and there was no big problem in other places because the phone was opened in time with a hair dryer. Not long after the phone was bought, he simply bought a screen assembly in a treasure and planned to replace it himself, so he disassembled the phone and installed the purchased screen, boot everything normal, test other hardware functions are normal, but it is a test WIFI signal, when the phone is from the router to compare the price into the case, the mobile phone WIFI signal is full, no abnormality can be seen. But the Internet speed is super slow, and the WIFI signal of the mobile phone is extremely poor. Is this due to the effect of changing the screen?
It is also possible to get accurate answers after reading a lot of posts on the Internet about the poor signal of mobile phones such as WIFI after the screen change. Now I would like to summarize the reasons for the poor signal of mobile phones after the screen change.
First check whether the signal cable is not properly connected. Secondly, check the connection point of the mobile phone signal wiring place, and the connection resistance is poor. To solve the problem, use a toothpick to stir up several signal resistance points, so that the signal wiring resistance of the back shell of the phone is normal. Moreover, most of the reasons are here, motherboard problems, many people repair the mobile phone screen screen, bad businesses with the mobile phone motherboard, resulting in mobile phone WIFI signal for various reasons. If you are outside the mobile phone after changing the screen, in the case of determining that the mobile phone motherboard does not have any problems, the WIFI signal is poor, after excluding the above problems, you can not solve the problem, please go to the after-sales point to detect the motherboard problem.
That is the technology of the person who changed the screen for you is not good, resulting in a problem with the wireless module, it is recommended that you try to restore the setting first, if not, find the place for you to change the screen for you to repair it
