Chapter 14 : Troubleshooting 215
Why this might help
Restarting your phone closes all applications, frees up all memory, and
reinitializes wireless services (phone, Bluetooth
®
technology, Wi-Fi, and
VPN). A fresh start.
Did this solve the problem?
• Yes : S to p.
• No: Continue.
T3. Triple-toggle to restart
1 Press and hold power .
2 While still holding down power , slide the ringer switch three
times.
Wait a few seconds for the restart to begin.
Or try this method for restarting your phone: 3-key restart: Press and
hold these keys—Option + Sym + R—and then release them all at
once. Give this method at least ten 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 reinitialize wireless services (phone,
Bluetooth
®
technology, Wi-Fi, and VPN).
NOTE Because open applications are forced to close immediately during this kind
of restart, some unsaved data may be lost.
Did this solve the problem?
• Yes : S to p .
• No: Continue.
T4. Top off the battery
1 Connect the USB cable to the AC charger and to your phone.
2 Plug the AC charger into a working electric outlet.
3 Let the battery charge completely.
Why this might help
The system may have shut down because of an error reading the charge
level. Fully charging the battery resets the charge value.
Did this solve the problem?
• Yes : S to p .
• No: Continue.
TIP An occasional restart can be good for your phone just the way a restart can be
good for your computer. Every once in a while, restart your phone.
