Hi, make sure that your camera lens is clear. Long press the Camera icon then select App Info or the "i" sign on the right side > Storage > Clear Catch and Clear Data. Make sure to transfer your photos in Camera folder inside the Gallery to a different folder. All you camera settings will be reset to default so you have to change it after those steps.
