Sony W8 Walkman keypad freezes after internet connection is on

After logging on my Sony W8 Walkman, it asks for new internet settings and keypad freezes. I am unable to gauge the problem as it usually occurs while checking status updates and emails. How it can it be fixed? Please suggest a solution.

hey friend...

There are few points whom you have to look upon so that your phone doesn't get overloaded and hangs...

- First of all is the internal space of your phone ... Always make sure that your phone's internal memory is always as free as possible

- Scan your phone for any virus and clear it off using good antivirus software
- There must be no multitasking in the phone without any use..
- Close all the background running apps or uninstall unnecessary apps from the phone
- Clear or delete all the cache , cookies , browsing history from the phone after using internet
- Clear saved cache files of all the apps also
- Also restart your phone time to time ....
- Update your phone and check for the latest updates available ..

thanks
