I've had two Galaxy S5's now. I realized that focusing in the dark, using an app such as WhatsApp or Google Googles or even the Messaging app is very tough. The camera just doesn't focus if it's not in bright light. Also, when I take a picture for an MMS, no matter whether I use the flash or not the picture comes out very dark. Much darker than what I see in the viewfinder. The picture in that one second preview we see is really bright and good but the ed result is terrible. Does anyone else face this same problem?
