My battery on my 8520 had doubled in size and i also got the white screen of death, but the battery still worked. but i had enough of charging it all the time, so i brought a new battery. the battery is the right one as ive looked it up several times and my chargers are working. however when i put my new battery in and put it on charge, the phone will not turn on and says there is no battery as the symbol comes up of a battery with a red cross. please someone help !!
