NOTE:
If the battery is extremely low, you may be unable
to power on the phone even when it is being
charged. In this case, try again after charging the
phone for at least 20 minutes. Contact the
customer service if you still cannot power on the
phone after prolonged charging.
NOTE:
If the screen freezes or takes too long to respond,
try pressing and holding the Power key for about
10 seconds to restart the phone.
