...the big chargable battery we all? my samsung cellphone is constantly lossing memory ( can't keep accurate date), shuts down when am receiving or attempting to make calls or scroll through the menus or search for any operation, even though the external big battery is almost fully charged, yet it I can't get it on for any lenght of time nor make or receive calls or messages from it.
Can it be due to some external or internal energy source making the BIOS/ROM or whatever internal storage for booting to keep loosing information or fade or what?
