Nikon Coolpix S52 Blurry Pictures?

I changed some settings on my Nikon Coolpix S52 and now all pictures are blurry, especially around the edges (even on the preview screen). I dont know what I did, how can I fix it? Already tried everything they recommend on www.nikon.com, reset all, troubleshooting, etc…

Suggest looking at the lens. You may have smudged it. Clean according to the manual (micro fiber cloth).
