Poor quality of
calling
Please check if the sound volume is tuned improperly
In an area with poor receiving condition, example: basement, the signal
might be weak. Try reaching a location with stronger signal reception and
call again.
While using the mobile phone in the peak period of communication, like
commute time, you may be unable to call because of line congestion.
Standby
duration
shortened
The standby duration is relative to the system setting of network. While the
mobile phone is in an area with poor signal strength and can not receive the
signal, the handset will continuously search for a base station. This will
significantly reduce battery charge. It is recommended that you turn off your
mobile in area with no signal reception to save battery. Need replacing the
battery. Please change a new battery.
