That is what my camera looks like, and trust me, my displays are not that bright, ive tried different apps, remove the lenses plastic cover and nothing seems to work, i even tried advanced mode, now all i ask is for a functional camera ASAP, ill be going out in 4 days.
Do you see that effect using the front-facing camera as well? Just trying to determine if it's a problem with the camera module itself, or the software processing.
Hmm, I wonder if there's actually some condensation within the camera lens itself (not the overlying camera glass). Not sure what else to suggest besides bringing it to a repair shop for further inspection.
