so, you need to make a short swipe left for the back gesture, and a full
swipe right or left for the next or previous open app.
• Likewise, you can't use the next/previous app gestures unless you turn
them on (see Turn advanced gestures on/off ).
• To check if you’re making the gesture correctly, see Use gestures: tap,
swipe, drag, flick, pinch .
There are small icons in the bottom right-hand corner of the
screen
Those icons represent notifications that you have not opened or dismissed.
For most types of notifications, if you do not tap a notification after a few
seconds, it becomes an icon in the bottom right-hand portion of the
screen. If you see one or more icons, tap anywhere on the bottom of the
screen to display your notifications.

Signal strength is weak
Become familiar with low coverage areas where you live, commute, work
and play. Then you know when to expect signal-strength issues.
• If you're standing, move about 3 metres in any direction.
• If you're in a building, move to be near a window. Open any metal
blinds.
• If you're in a building, move outdoors or to a more open area.
• Outdoors, move away from large buildings, trees or electrical wires.
• In a vehicle, move your smartphone so that it's level with a window.
My smartphone doesn't connect to the mobile network
• Try the suggestions in Signal strength is weak to improve a weak signal.
• Turn off the phone and turn it on again by turning aeroplane mode on
and off (see Turn your smartphone on/off ).
• Set your smartphone to work with 2G networks or 3G networks only
(see Set roaming and data usage preferences ).
• Restart your smartphone (see Restart your smartphone ).
I see five bars in the signal-strength icon, but I still can't
connect to the network
The signal-strength icon always displays five bars. Your signal
strength is indicated by the number of bars that are shaded white.
If most or all of the bars are white , you are in an area of strong
coverage.
If most or all of the bars are grey , you are in an area of weak or no
coverage.
The person on the other end of the line hears an echo
• Try decreasing the volume on your smartphone—whether you are using
the speaker or the earpiece—to avoid coupling or feedback at the
other person's end.
• Position the earpiece closer to your ear to prevent sound leaking back
into the microphone.
• If you're using the speakerphone feature with your smartphone lying on
a flat surface, try turning the smartphone face down (screen facing the
surface).
I hear my own voice echo
Ask the person on the other end of the call to turn down the volume on his
or her phone or to hold the phone closer to his or her ear.
