Autofocus should keeps things sharp, however, are you aware that you can also tap the iPhone display to selectively focus on anything in the picture? You also might try holding the camera button until you've got everything framed properly, tapping on an object or face to make sure that part is focused, then releasing the camera button to actually take the picture.
Thank you. Your reason may be valid but not for me. Sorry, the problem was due to a little foolishness. I didn't uncover the newly bought iPhone to protect from contamination. Actually the problem was due to this plastic cover. Now I'm going to trip everything from iPhone and make my iPhone nude 😉
Problem solved.
Thanks once again.
Try to reoptimize your pictures. I deselected the folders for selected photos synced then re-selected the photos and they are fine. This problem happened after I went to OS4.
I have a similar problem. The photos I took with my iphone are all ok. But the pictures I had in from my PC (windows 7 ultimate) are all shown with low detail, they are "pixelized". The wierd thing is that the one picture I have as wallpaper is iphone desktop is clear, but when i look it from the folder in iphone, along with the others of course, is same low "pixelized" detail. Anyone knows how to fix it? Or should I wait for apple's patch or next update?
I delete the pictures in my iphone from itunes library then I sync so it delete all & resync from a file I had them in my pc(not the photos taken by it, the ones i put in ihpone from my pc (downloaded pictures)). I restarted the iphone and all is ok now.
