Are you having trouble with the large size of the photos you take? This app always shoots at Full HD (1920 x 1080) size, and keeps the size of each photo to 500KB to 1MB. The following can be done in the options. -Turn location recording on/off When the icon is light, it's off. -Turn shooting at the same resolution as the Photos app on/off When the icon is red, it's on. -Torch (Flash) On/Off When the icon is red, it's on. Tap anywhere on the screen to lock the focus at that position. When locked, a target icon will be displayed; tap this to unlock it. It uses a torch instead of a flash, so there's no difference in the image you get with flash photography. It can also be used as a magnifying glass while the torch is attached.
