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.
