Recently, a magnitude 5.5 earthquake occurred in Pingyuan County, Dezhou City, Shandong Province, with a focal depth of 10 kilometers. The earthquake was clearly felt in many provinces, including Beijing, Tianjin, Hebei, Jiangsu, Henan and other places. Many netizens said that they were woken up by the earthquake warning sound from phones, TVs and other equipment.
Earthquake early-warning is a technology that uses the difference in the propagation speed of seismic waves to issue an early warning before the arrival of seismic waves. At present, almost all domestic mobile phone brands provide earthquake early warning functions, such as Huawei, Xiaomi, Vivo, OPPO and so on.
However, some netizens found that the earthquake warning function of Xiaomi phones is turned off by default and needs to be turned on manually by the user. This has aroused the doubts of some netizens, why is such an important life-saving function not enabled by default?
In this regard, Redmi phone marketing manager Zhang Yu responded on Weibo that the scene and form of the earthquake warning itself is quite special, and it is enabled by default before the user is fully aware of the function. When the earthquake comes, it is likely to cause user panic and cause extra Personal safety accidents, so after the function is turned on, it is necessary to watch the demonstration of the reminder to avoid unnecessary panic.
Zhang Yu also said that since some cities do not support the earthquake early warning function, his current method is to find other nearby cities to enable it in case of emergency.
In addition, if you want the earthquake warning function of the phone to trigger the reminder normally, there are two details that need to be paid attention to. First, the phone must remain connected to the Internet. This is the bottom line. Second, when activated, the system ignores the volume status and screen brightness status of the phone. , by default, the sound will be full and the brightness of the phone will be full, even if you are Do Not Disturb.
Zhang Yu also introduced the method of enabling the earthquake warning function of Xiaomi devices, which is attached below:
Turn on the speaker: Xiaoai Speaker App → More → Earthquake Broadcast;
Turn on the phone: Settings → Search MIUI Alert Center/Mobile Manager → Alert Center.
