Yesterday, I was at Balboa Park during a parade which had a couple hundred thousand attendees. Whenever that many people get squeezed into a tight venue, such as a stadium, cell phone connectivity becomes an issue – and yesterday was no exception.
At one point, I launched an app on my iPhone which was taking a long time to open up since it needed Internet access. Just as I closed the app it popped up three modal dialog windows in a row. The app was closed, but the modal windows blocked all other iOS interactions as if the phone was frozen.
Restarting the iPhone
To restart the iPhone, all I needed to do was press the volume up, volume down, and then the sleep/wake button. This brings up a slider at the top of the screen, "slide to power off." But, the problem was this slider was blocked by the modal window.
I tried pressing all three buttons and holding them down. Unfortunately, this activated the phone's emergency mode which dialed 911 and then sent out SOS text messages to my emergency contacts with a map of my location. The police called me back with an automated message stating that they received a hangup call but couldn't pinpoint my location. However, even though my phone had location services turned off, it seems the phone was able to know my location and sent a pin-drop to my emergency contacts along with an SOS message.
Force Restarting the iPhone
What I needed to do was force restart my iPhone, but I didn't know how. Luckily, my buddy had his iPhone (also with spotty connectivity) and we did a Google search. A force restart is similar to a typical restart, except you hold down the sleep/wake button until you see the Apple logo:
1. Press the volume up button.
2. Press the volume down button.
3. Hold down the sleep/wake button until you see the Apple logo (5-10 seconds).
