Google Android Camera Focusing Issue

A couple of my friends have the new Android phone and I’ve got to say, from the little bit of time I’ve spent playing around with them, it’s a nice phone. There are a number of apps available and it’s got some nice media coverage. It’s from Google so you know the phone’s gotta be perfect right? Umm…

It appears that users are experiencing a little bit of an issue with the camera that’s part of the Android phone. The Android’s 5-megapixel camera’s auto-focus feature isn’t always working. You’d think it might be some kind of issue with a faulty lens or the auto-focus mechanism. It turns out it’s all in the programming though.

The issue is due to a rounding issue with the auto-focus programming routine. The auto-focus function uses a time stamp (not sure how that works or why?) that’s set on a 24.5 day clock. So, every 24.5 days the camera can’t focus. That shouldn’t be a problem though right? I mean really? What happens within 24.5 days that won’t happen again?

The good news is, there’s a patch coming soon to fix the issue. Now, will someone please explain to me why an auto-focus programming routine is based on a timestamp?
