Please read this before you start using your phone!
Please check to see whether any problems you encountered with your phone are 
described in this section before taking the phone in for service or calling a service 
representative.
1.  Phone memory
When there is less than 10% of space available in your phone memory, your phone 
cannot receive new messages. You need to check your phone memory and delete some 
data, such as applications or messages, to make more memory available.
To uninstall applications:
1  Touch  > Apps tab > Settings > Apps from the DEVICE.
2  Once all applications appear, scroll to and select the application you want to 
uninstall.
3  Touch Uninstall.
2.  Optimizing battery life
Extend your battery's life between charges by turning off features that you don't need 
to have running constantly in the background. You can monitor how applications and 
system resources consume battery power. 
Extending your phone's battery life:
• Turn off radio communications when you're not using. If you are not using Wi-Fi, 
Bluetooth or GPS, turn them off.
• Reduce screen brightness and set a shorter screen timeout.• Turn off automatic syncing for Gmail, Calendar, Contacts and other applications.• Some applications you have downloaded may reduce battery power.

remember the Backup PIN you created when creating your pattern lock.
 WARNING
Precautions to take when using pattern lock.
It is very important to remember the unlock pattern you set. You will not be 
able to access your phone if you use an incorrect pattern 5 times. You have 5 
opportunities to enter your unlock pattern, PIN or password. If you have used 
all 5 opportunities, you can try again after 30 seconds.

pattern 5 times, touch the Forgot pattern? button at the bottom of the screen. You are 
then required to log in with your Google Account or you have to enter the Backup PIN 
which you entered when creating your Pattern Lock.
If you have not created a Google account on the phone or you forgot Backup PIN, you 
have to perform a hard reset.

6.  Opening and switching applications
Multi-tasking is easy with Android because you can keep more than one application 
running at the same time. There is no need to quit an application before opening 
another one. Use and switch between several open applications. Android manages each 
application, stopping and starting them as needed to ensure that idle applications don't 
consume resources unnecessarily.

app while using an app. This does not stop the previous app running in the 
background on the device. Make sure to touch the Back key 
 to exit an 
app after using it.

sync (MTP)
