You need to upgrade the software (firmware) on your phone. It should solve the problem.

You need to download the latest Sony Ericsson PC Suite to do an update on your phone.
Before updating software you should check that there’s a newer version of software available. The Sony Ericsson website will guide you through.

WARNING
When updating software on Mobs, be sure to:
HAVE A FULLY CHARGED BATTERY INSERTED;
PUT IT ON GENERAL PROFILE;
TURN OFF YOUR PIN NUMBER;
CONNECT YOUR CHARGER TO YOUR MOB AND SWITCH IT ON;
DO NOT ----- DO NOT ---- TOUCH YOUR PHONE WHILE THE UPDATE IS GOING ON;
THIS CAN TAKE 30 MINUTES OR MORE.
And obviously don’t unplug the phone from the PC.
Be patient, you may have to do a restart or two on your mob afterwards. Even remove the battery to get it going again (not recommended). But give it plenty of time.
It is also wise not to use your PC while updating software, just in case the PC freezes.
If the PC freezes during an update, you’re up the creek without a paddle...

I did an update on a Sony Eric 810i it took nearly two hours.
More... Your phone turns itself on and off, sometimes more than once while updating software, you should leave it well alone during the update.
If you're not sure about doing this, get a repair/sales shop to do it for you.
