Hi everyone. I bought a new update on June 16. however, a significant reduction in image quality encountered after updating. I went back to the factory settings, reset your phone, I did install the firmware again, but the problem is resolved. if it was not clear, such as pictures taken in a smoky environment. After all did not understand, but the result of a long struggle back to the old software installed and the problem solved. I installed 4.0.4 again. I saw the problem still continues. I went back to 2.3.4 again. :). I mean, think before you install the latest update. I'm sorry for my English. good day everyone. thanks google translate ...
The image quality is set as 3mp as default try setting it to 5mp and see if it improves.
Good point by phoenix_786, check it out! 
What do you think about this forum? Let us know by doing this short survey.
yes, I know. I checked all the settings and changed. 4.0.4 all works fine except the camera. I checked every place I used the new software in two days. I returned the old software just did not like the quality of photos.
Petter and phoenix_786, increasing resolution also increases noice. Reducing resolution reduces noice. So, on 5mpix setting there would be even more noice than on 3mpix. You should know that. Regards.
Have you tried a third party camera app.
