How can I take photo when battery level is less than 20%? My Samsung Galaxy S always says "battery low" and then closes the camera application when I try to. Is there a way to get around this? Or is 19% not powerful enough to take a photograph (my camera has no flash).
Try downloading and using a third-camera app from the market. The restriction is apparently on the stock camera app, not on the hardware (the camera itself). I downloaded Retro Camera, and it is able to take a picture when my Galaxy S is on low battery. That might not be the app you want, so do a search on the market with the keyword "Camera".
