Hi,
I also have the same issue with my iPhone 5.


After a few times I started a service request and sent my iPhone in for repairs.
2 or 3 days later it came back with the status:
- May 7, 2013: Product received by service center
Shipped via UPS with tracking number XXXXXXXXXXXXXXXXXX
- May 9, 2013: Could not duplicate issue
- May 9, 2013: Original product shipped
Shipped via UPS with tracking number XXXXXXXXXXXXXXXXXX
After a few days the problem appeared again and I sent it in for repairs again.
Then finally I got a replacement handset.
- May 17, 2013: Product received by service center
Shipped via UPS with tracking number XXXXXXXXXXXXXXXXXX
- May 17, 2013: Service completed
- May 17, 2013: Replacement product shipped
Shipped via UPS with tracking number XXXXXXXXXXXXXXXXXXX
After about 1,5 weeks the same issue appears on this handpset, too.
That's so confusing, so weird, so annoying! I can't believe it that a first class quality item has an issue like this! Where is Apples quality control? Or let's say Foxconns quality control!!!!!
I'll drive to an official Apple Store and will replace my handset with a new one on a Genius Bar.
My working mate had the same issue with his iPhone 5 but very rare & occassionnally.
I researched the serial numbers of my 2 devices (old one and replaced one) and the handset of my working mate on this website: http://www.chipmunk.nl/klantenservice/applemodel.html
My replaced iPhone 5 was built in PRODUCTION WEEK: 05 - PRODUCTION YEAR: 2013
My new iPhone 5 was built in PRODUCTION WEEK: 51 - PRODUCTION YEAR: 2012
The iPhone 5 of working mate: PRODUCTION WEEK: 52 - PODUCTION YEAR: 2012
Maybe there is a fault with the camera devices which has been delivered to Apple (Foxconn) between NOVEMBER, DECEMBER 2012 and JANUARY 2013?
I don't know. It's just an idea. Which Production Date do you have on your faulty handsets? Check it here and post it on this Thread. Let's see, which production weeks have faulty camera devices.
