18. Troubleshooting
The phone does not switch on
Remove/reinstall the battery. Then charge the phone until the battery icon stops
scrolling. Unplug the charger and try to switch the phone on.
The display shows BLOCKED when you switch on the phone
Somebody tried to use your phone but didn’t know the PIN code nor the unblocking code (PUK).
Contact your service provider.
The display shows IMSI failure
This problem is related to your subscription. Contact your operator.
The network symbol is not displayed
The network connection is lost. Either you are in a radio shadow (in a tunnel or between tall
buildings) or you are outside the network coverage area. Try from another place, try to reconnect
to the network (especially when abroad), or contact your network operator for assistance/
information.
The touch screen responds slowly or improperly
If your device has a touch screen and the touch screen is not responding properly, try the
following:
-
Remove any protective covers from the touch screen. Protective covers may prevent the
device from recognising your inputs and are not recommended for touch screen devices.
-
Ensure that your hands are clean and dry when tapping the touch screen.
-
Restart your device to clear any temporary software bugs.
-
Ensure that your device software is upgraded to the latest version.
-
If the touch screen is scratched or damaged, take it to your local dealer.
Your battery seems to over heat
You might be using a charger that was not intended for use with your phone. Make sure you
always use the authentic accessory shipped with your phone.
Your phone doesn’t display the phone numbers of incoming calls
This feature is network and subscription dependent. If the network doesn’t send the caller’s
number, the phone will display Call 1 or Withheld instead. Contact your operator for detailed
information on this subject.
You can’t send text messages
Some networks don’t allow message exchanges with other networks. First check that you have
entered the number of your SMS centre, or contact your operator for detailed information on this
subject.
You can’t receive and/or store JPEG pictures
A picture may not be accepted by your mobile phone if it is too large, if its name is too long, or if it
doesn’t have the correct file format.
You feel that you have missed some calls
Check your call divert options.
