Samsung cell phone batteries?

Oh! It a pity that your GALAXY S facing such problems. I also had the same phone but it worked perfectly all right, I faced not any single problem as you are facing. As it have been so less days of your SAMSUNG GALAXY so the chance of battery fettle is very less, just get checked up with its battery pins . some time it happens that carbon collects on the pins and same problem is faced as in this case cell phones fails to get proper power supply. Take a scratcher and rub that on the battery pins, I think this will solve your battery backup problem to some extent. If still it does not work then sorry, you have to change your battery. Down to your next worry of application, it is not a big one just go into setting of the cell phone and click on the RESTORE setting option// this will format your cell phone and bring your cell phone in the original condition. Other things you can do regarding your cell phone’s application is update it using web portals.
