TIFU by updating my phone

For the past few weeks I've been getting an update notification for my phone. I kept ignoring it, as one does, but I decided to just get it over with. So my phone updated, I turn it on: it wouldn't let me unlock it. So I shut it off, turn it on, again it won't unlock. Eventually I got it to unlock, the update conpleted and I put my phone down to go to bed.

I turn over in bed, trying to fall asleep. My phone keeps lighting up and I'm ignoring it, thinking its notifications from the update. It was not.

I roll back over to see why my phone keeps going off and get an incoming call from my brother. He works nights so its not unusual that he's up, but its very unusual that he's calling me at 3 am.

"Where are you?" Is the first thing he said.

"In my room...why?"

He goes on to tell me that I sent him, my mother, my father, and my best friend an SOS message, black images, and an audio clip. My heart dropped into my stomach.

I had enabled the SOS setting months ago when I went away to school. In my fumbling as I tried to unlock my phone, the repeated pressing of the power button had set off said setting. The people closest to me had believed I'd been kidnapped.

The only shining sliver of good in this story is that no one called the police. I cleared it up with my family and sent an urgent text to my friend to ensure she didn't go into cardiac arrest. I did have to get out of bed and video call my crying mother, however, so she could make sure I was really safe. The SOS setting has since been disabled to avoid such an accident.

TLDR: I updated my phone and accidentally set off the SOS feature leading to my family and best friend believing I was in immediate danger. Situation was clarified, no cops called, and the sos feature is disabled.
