If you are experiencing any data issues, we recommend performing a data profile update. This will refresh your data service parameters such as username and password and help clear out any memory issues that might be affecting your phone.
To update your profile:
From the Home screen, press Menu
Scroll up and tap About phone
Tap Sprint System Updates
Tap Update Profile
Your phone will check for updates and once updates are complete, you will see the message: Phone is activated!
Tap Next to return to the Home screen
By power cycling your phone, you will be able to re-register your phone with the network, which may correct slow down issues, data connection issues and other problems.
To power cycle your phone:
WARNING: For PDAs and smartphones, performing a power cycle may cause the loss of some unsaved data or information. Before removing the battery, we recommend you save any data or information you want to keep.
Turn the phone off
Remove the battery
Reinstall the battery
Turn the phone on
Note: It can take several minutes for the phone to restart after removing the battery. It is normal for a white screen and timer icon to display during startup – it is not an indicator that the phone is locked or frozen.
If you recently downloaded an application and noticed a difference in your Nexus S 4G performance, the new application may be causing the problem. To troubleshoot this:
Uninstall the new application
Power cycle the phone
It should now perform as expected. If it does, then you can try to reinstall the application.
If you continue to have problems after you reinstall the application, we recommend you uninstall it.
If the application came from a third-party vendor and not from a Sprint site, contact the application provider to help you work through the problem. Please keep in mind that if the application you downloaded came from a Web site other than sprint.com, it may not be a Sprint-supported application.
If you continue to have problems after uninstalling the application, or the application was downloaded from sprint.com, please contact us.
