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 cannot 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.
