Troubleshooting
Another caller cannot hear you
speaking.
• Ensure that you are not blocking the
built-in microphone.
• Move the built-in microphone closer to
your mouth.
• If using a headset, ensure that it is
properly connected.
The sound quality of a call is poor.
• Ensure that you are not blocking
internal antenna.
• When you are in areas with weak
signals, you may lose reception. Move
to another area and try again.

The battery does not charge properly
or sometimes your device turns itself
off while charging.
• Disconnect the device from the
charger, remove and reinstall the
battery, and try charging again.
• The battery terminals may be dirty.
Wipe both gold-coloured contacts with
a clean, soft cloth and try charging the
battery again.
• If the battery no longer charges
completely, dispose of the old battery
properly and replace it with a new
battery.
Your device is hot to the touch.
When you use several applications at
once, your device requires more power
and may heat up. This is normal and
should not affect your device's lifespan or
performance.
