* View iPhone Signal: Easy-to-Use Tutorial As one of the world's leading mobile devices,Plastics (HS code ) import analysis although it is powerful, it also has the problem of signal instability. With the development of the times, some places may have weak signals or signal blind spots. And when users encounter similar problems when using iPhones, they need to be able to accurately check the current signal strength in order to solve the problem effectively. The following is a simple and easy-to-use tutorial to teach you how to check the current signal strength through iPhone.I. Check the signal bar on the iPhone. The easiest way to check the signal strength is to observe the signal bar in the upper left corner of the screen. There are several small dots on the signal bar, which represent the number of network signals of the current mobile phone. The more dots there are, the stronger the signal. Generally speaking, there are 5 points in total. When all of them turn black, it means that the current signal is the strongest. However, the signal bar is only one way to show the current signal status, and it is not completely accurate. Because the signal bar is a simple signal indication system that comes with the iPhone system, it cannot directly reflect the real situation of the network environment. If you want to understand the network quality more comprehensively, you need to rely on the hidden functions of iPhone. II. Check the digital signal. In addition to the signal bar, there is also a hidden digital signal in the iPhone to help solve network problems.The following is the way to check the digital signal: Step 1: Dial * 3001#12345#*, and then click Dial. Step 2: Open the test menu and enter "Field Test", which will show a lot of text-like information. Step 3: In the "Field Test" menu, find "RxQual". It represents the quality of the received signal, ranging from 0 to 7. Greater than or equal to 5 is considered good, around 4 indicates a low signal failure level, about 2 indicates poor signal, and the smaller it is, the worse the signal is. Step 4: Find the position of "Serving Cell Measurement" and see "rsrp0" and "rsrq0" here. Among them, "rsrp0" refers toIt is the signal strength (the smaller the signal strength, the stronger the signal strength), and "rsrq0" refers to the signal quality (the closer to 0, the better). III. Use third-party signal testing software. Of course, if you find this method complicated, you can also use third-party signal testing software to understand the signal quality. These software continuously monitor the signal status of the mobile phone and remind you when the signal is unstable or the signal blind spot. In the App Store, users can find many apps that provide signal testing services. They only need to download a tool that can query network signals and actually test network speed. Finally, reminder: No matter which signal test method is used, there is one thing that needs special attention, that is, the network situation is different in each place. Therefore, we should try to test and analyze as many times as possible to draw the most accurate signal quality conclusion.If there is a problem with the signal quality, it can be solved by resetting the network settings and trying to switch different operators. It is worth mentioning that if you find problems such as signal when using your iPhone, you can also contact Apple's customer service to consult their opinions. In a word, even if it is a high-quality mobile phone, the signal will be unstable. When you feel that the mobile phone signal is unstable, using the above methods can help you more accurately understand the current signal quality and network quality, so as to solve the problem quickly and effectively.
