Edit: Guys, I know that it is easier to hit “dismiss” or any other button on the person’s phone. You can stop telling me this. This tip is for when you can’t or don’t feel comfortable doing so. I did this when my coworker’s alarm went off. I called her phone because I didn’t feel comfortable touching her phone. I didn’t want to be accused of invading her privacy or touching her property without her permission. Use your common sense.
