186 Chapter 14 : Troubleshooting

2 Throw the app off the top of the screen to close it.

3 Throw any other open applications off the top of the screen to close

them.

Why this might help

One or more of your open applications could be reserving so much

memory that there's not enough memory left to do real work. Closing

apps can free up enough memory so you can continue working.

T2. Turn your smartphone completely off and on

NOTE If the screen is off and you can't turn it on or if gestures don't work, skip

to T3. Triple-toggle to restart.

1 Press and hold the power button.

2 Tap Power and then tap Restart.

Why this might help

Restarting your smartphone closes all applications, frees up all memory,

and reinitialises wireless services (phone, Bluetooth

technology, Wi-Fi

and VPN). A fresh start.

T3. Triple-toggle to restart

1 Press and hold the power button.

2 While still holding down the power button, slide the ringer switch

three times.

Wait a few seconds for the restart to begin.

Or try this method for restarting your smartphone: 3-key restart: Press

and hold Option + Sym + R and then release the keys all at once.

Give this method at least 10 seconds for the restart to begin.

Why this might help

A triple-toggle or 3-key restart may be effective if the screen is off and you

can't turn it on, or if gestures don't work. These restarts also close all

applications, free memory and reinitialise wireless services (phone,

Bluetooth

technology, Wi-Fi and VPN).

NOTE Because open applications are forced to close immediately during a

triple-toggle or 3-key restart, some unsaved data may be lost.

TIP An occasional restart can be good for your smartphone just the way a

restart can be good for your computer. Every once in a while, restart your

smartphone.
