I own LG GW620... Few days before i noticed that the backlight of the left softkey(home button) is not glowing and my camera is showing a black dot on the screen... So i went to the service centre and after the half an hour checkup of my fone they said that they need to format my fone....i was like WTF?? I asked them and said that this is the hardware prob and even i myself formatted the fone but they are saying that............. So, what shud i do??
