My daughter's phone has started doing something very strange with her contacts - if you enter a number and save it - when you go back to that contact the number has changed - it seems to another number in her address book - it's really bonkers. The phone is only a couple of months old - should we send it back or is there anything we can do? Also she says she has problems hearing people she calls but his is probably a different issue.
Make sure you make a backup of all your personal data e.g contacts ec and then download a program called Sony Ericsson Update Service and update the phone and check if that resolves your issues.
