Movement in bright light
If an image is taken of moving objects or if the device is used in a moving vehicle, object 'skewing' or 'tilting'
may occur. This phenomenon is fundamental to most CMOS camera types, and usually cannot be avoided. The
movement of camera or object sometimes cause blurring indoors or in dim lighting conditions because of long
exposure time.

Temperature
High temperatures inside the mobile phone cause more noise to appear in images. For example, in +70 degrees
(Celsius), the noise level may be very high, and it further grows if the conditions are dim. If the phone processor
has been heavily loaded for a long time before taking an image, the phone might have considerably higher
temperature inside than in the surrounding environment. This is also normal to camera operation; do not
change the camera module.
