Last Sunday, the 23rd, the citizens of UK heard alarms going off on different cell phones. The sound emitted was part of the tests used by the British government alert to announce the approximation of risk situations, giving people time to prepare in different times.
The alarm can sound on silent devices in cases of exposure to fire, flood, terrorist acts and others. iOS and Android devices, with 4G and 5G connections, even if they were silent, could sound the alarm.

Although it seems like a new system, other countries adopt the same security measure.
Alarm system in telephone sets
These mobile shots are now available in Canada, the United States, the Netherlands and Japan. These countries make use of loud sirens, as well as in Brazil, but have implemented security measures to avoid possible fatalities.
In the UK, the cell phone test took place shortly after the siren sounded.
Along with the siren, the British government hoped the test would work on all devices, but the tests did not go as well as planned. The plan faced technical problems and some people didn't hear the alarm going off on their smartphones.
Another hypothesis raised a problem during testing
It is a preventive action so that the British are even safer, but they raised other relevant hypotheses. Women who suffer from domestic violence, in cases of cell phone shooting, would have possible security devices discovered by their abusers.
Knowing this, all women living at risk were instructed to turn off their hidden devices so that the test could be carried out.
In this regard, the tests presented safer solutions, despite having failed for other people. It is likely that this was the first trial of the alarm to predict risky situations in the UK.
