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 recognizing 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 tablet. Make sure
you always use the authentic accessory shipped with your tablet.
Your tablet does not display the phone numbers of incoming calls
This feature is network and subscription dependent. If the network does not 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 not send text messages
Some networks do not allow message exchanges with other networks. First check that you
have entered the number of your SMS center or contact your operator for detailed
information on this subject.
You can not receive and/or store JPEG pictures
A picture may not be accepted by your tablet if it is too large, if its name is too long, or if
it does not have the correct file format.
