11.  Unlock screen when 

using data connection

Your display will go dark if 
untouched for a period of time 
when using data connection. To 
turn on your LCD screen, just 
touch it.

Note: When uninstalling PC 
Suite IV, USB and Bluetooth 
Drivers are not automatically 
removed. Therefore, they must 
be uninstalled manually.

Tip! To use a micro SD card on 
your phone again, you need to 
open the Notifi cation drawer and 
touch "Turn off USB storage".

During this time, you can’t 
access the micro SD card from 
your phone, so you can’t use 
applications that rely on the 
micro SD card, such as Camera, 
Gallery and Music.
To disconnect your phone from 
the computer, carefully follow 
your computer’s instructions 
to disconnect USB devices 
correctly, to avoid losing 

information on the card. 

Safely disconnect the USB 
device on your computer.
Open the Notification drawer 
and touch Turn off USB 
storage.
Touch Turn off USB Storage 
in the dialog that opens.

12.  Hold phone up right

Please hold the mobile phone up 
right as a regular phone.
While making/receiving calls or 
sending/receiving data, try to 
avoid holding the lower part of 
the phone where the antenna is 
located. It may affect call quality.

13. When Screen freezes

If the phone does not respond to 
user input or the screen freezes:
Remove the battery, insert it 
again and turn the phone on. 
If it still does not work, please 
contact the service centre.
