Hi I've had my Galaxy S since December 2010 and in the time I've had it the phone has at least 4 times decided to switch off on me and so I have to remove the back and battery to get it working again. It's also been turning off overnight and I've found the next day battery needs to be recharged. I know it's not been happening too much but with it being still less than a year old should I take it back to Carphone Warehouse and see if it can be repaired? It's not been rooted or anything and I'm using Gingerbread 2.3.3 software. I have tried reinstalling the software but it's still happens. Many thanks for any help offered.
