The iOS 11.2.1 update released this morning appears to address an ongoing camera focus issue that some iPhone X, iPhone 8, and iPhone 8 Plus users began experiencing following the release of iOS 11.2.

According to affected users, the camera was not able to focus properly when attempting to capture an image. The camera either shifted continually between the two lenses of the iPhone X and the iPhone 8 Plus, or refused to focus entirely. From MacRumors reader Nixie:
Hello there, was wondering if anyone have this issue too, when on iOS 11.2 the camera isnt able to get in focus, the lense just go back and forth indefinetly. Restored back to 11.1.2 and the issue is gone, updated back as new iPhone on 11.2 issue is there. So this looks like a software problem. Anybody with the same problem?
Resetting, restarting, and changing camera settings did not address the issue, but downgrading to iOS 11.1.2 did, suggesting it was caused by a bug in iOS 11.2.

MacRumors readers on Twitter and the forums who were experiencing the problem have said that installing iOS 11.2.1 has resolved the autofocus issue.

iOS 11.2.1 is available as a free download that can accessed by going to Settings --> General --> Software Update. In addition to fixing the autofocus issue, iOS 11.2.1 also re-enables remote access for shared users of the Home app, which Apple disabled last week to address a major HomeKit vulnerability.

How about fixing the freaking iTunes player ALWAYS showing up on my lock screen. This just started with 11.2 at least for me. Nothing makes it go away. I don't need it, don't want it and it's blocking messages I'd prefer to see.

Midwest America.
I was wondering. I tried to take a picture, and couldn't get my 8+ to focus. I had to touch the image area a few times, and it finally seemed to focus. It did seem odd. I even checked the lens to see if it were something on it. Good to know it wasn't me. It's Apple Quality unControl...

I'm good on focus, but my desk lamp is a phillips hue bulb, and I get vertical lines if I try to take a picture of something on my desk due to some sort of camera vs light refresh phasing :confused:

I haven’t really used the camera on my X much until a recently holiday and I started to worry because the photos were very hit and miss. Some where amazing and some brightly lit scenarios looked like they were taken on a 3GS at best. Hope this fixes it...

Didn't have this issue, although good to know it's fixed.

However is Apple not going to address front speaker crackle at anywhere near high volume/ringtone? :confused:
I guess I'll wait till Jan, if not, then just might have to take it in for a replacement.

Yes, but does 11.2.1 restore my battery life to what it was prior to my having installed 11.2? With 11.2, I only get 3 hours 45 minutes of usable battery life. I have friends who've told me the same after installing 11.2 on their iPhone 7's.

I hope this to be the case.
My X battery with 11.2 is atrocious compared to before
