Have you switched off/on, and it's the same? I've got a Sony Ericsson phone and taking out the battery and putting it back in sometimes resolves freezing issues.

I have a v640i that needs to be charged after 24 hours and it is the second one iv tried.


I managed to speak with a rep from Sony he seems to think 24hours between charges is ok. Now my old telecom phone would last a week before needing a charge doing the same work it is just a shame telecom are not a very good company. So i guess any one going to buy a phone be aware the modle Sony v640i needs charged every 24 hours. ( no i dont agree that a phone needs charged that often and think the rep just wanted to get rid of me )
