Just bought an S3 and have some difficulties shooting in-doors and evenings. Without flash in-doors, the pic looks dark even when the lighting is bright enough eg. supermarkets in SUNTECH city. As for evenings, at 6.50pm onwards, using flash, the background in completely dark. Looks like 9pm. When switch to pre-programed nite mode, pic is blur but the lighting is good. Can anyone help?
