As many of us today are fond of putting password/patterns on our phones which makes it difficult for someone to access it in case of unfortunate situations like phone loss, sickness, accident or even death. But with these few steps, perhaps we can save ourselves and the lives of others also.
When your phone is locked, it normally shows enter password, under it you will see emergency. Click on the emergency, then you will see emergency information. Click on the emergency information (2 times). You will see a pencil icon on your extreme right, click on it to edit.
Then enter the contacts you want to save as emergency. You can put as many contacts as possible but I advice you save numbers of active people who know you very well (Family/friend).
Now these contacts you have saved can be called even when your phone is locked without entering your password.
To call a number under emergency, you must repeat this process above.
