Little-known phone feature could save your life but most people don't know about it

Specialists are encouraging people to activate a crucial hidden smartphone function that could prove lifesaving during a medical crisis. Countless mobile users remain oblivious to the fact their handset includes an integrated emergency details feature, enabling ambulance crews, emergency responders and any bystanders to view vital health information when you cannot communicate.

This feature gives access to details including allergic reactions, prescribed medicines and urgent contacts, all without needing to bypass your phone's security. Though available as standard across both iPhone and Android handsets, professionals claim it ranks among the most neglected safety resources available.

Laura Bremner, a paramedic boasting more than 12 years of frontline expertise, said: "I have been trained to check phones for emergency info straight away.

"If it's filled in, we can make quicker decisions about treatment and contact next of kin faster. It really can make a huge difference when time is critical," she added.

Technology specialists at Zextons detail the setup process for this function. iPhone users should launch the Health application and select the Medical ID section. Next, press edit and input any health conditions, reactions and tablets you consume. Additional options include recording blood group and body weight, plus listing urgent contacts ranging from relatives to flatmates, reports Bristol Live.

Make certain to activate 'Show When Locked' to ensure the data remains viewable without entering your security code. Finally, press 'Done' to store your details.

If you fancy taking it a step further, in Settings, tap Emergency SOS. Here, you can switch on crash detection and automatic emergency calling, which could potentially speed up the arrival of help in emergencies.

For Android users, navigate to Settings and select 'Safety and Emergency', though this might be listed as 'Emergency Information' depending on your device.

Next, add your medical details and add any emergency contacts. Make sure 'Show on Lock Screen' is toggled on so your information can be quickly accessed when needed.

You can also activate the Enable Emergency SOS on Android devices, which allows five rapid presses of the power button to dial 999 and share your location.

Zextons experts advised: "Whether you're out walking alone, commuting or simply living day to day, this quick setup could provide emergency responders with exactly what they need when seconds count."

This hidden but crucial phone feature comes in handy whenever you're unable to contact the emergency services. It doesn't take a long time to set up; just a few clicks could save your life!
