[Q] The Camera is unable to Focus

view story

http://forum.xda-developers.com – My girlfriend's N7000 used to be able to take close up pictures and it would autofocus. A few weeks ago it stopped focusing and all the pictures came out blurry. At that point, she was using stock ics 4.0.3. I tried installing other camera apps on it and it didn't help. I rooted the phone and cm10 on it and that still did not fix the problem. I have tested the picture taking at the same condition and lighting condition with my phone. Her phone just doesn't focus at all. Please tell me what I can do. Thanks. (HowTos)
