There is a guy named Dan Morrill who works on Android at at Google. This was posted in the comments in the Engadget article I posted earlier. Is this the same guy? Don’t know.
Yes, this is exactly what is happening.There’s a rounding-error bug in the camera driver’s autofocus routine (which uses a timestamp) that causes autofocus to behave poorly on a 24.5-day cycle. That is, it’ll work for 24.5 days, then have poor performance for 24.5 days, then work again. The 17th is the start of a new “works correctly” cycle, so the devices will be fine for a while. A permanent fix is in the works.
A few people have said they’ve reset the date backwards a few days and had the issue return, but others have said otherwise. Who knows? There’s an over-the-air update that’s supposed to be out around December 11, and that’s 24.5 days from today.
What are the chances? I’d like to see this somewhere else with Google or Motorola’s name on it.
