iOS 11 - Clock on lock screen disappears

Mine was being caused by the wallpaper I was using for the lock screen. I haven't had the problem again since I changed the background. It's been over a week now. It used to happen once or twice a day. I guess it didn't like image for some reason.

the only permanent fix that seems to have fixed the issue for me was to turn off all my widgets except for the weather, calendar and news widgets. I'm going to start turning on my other widgets one by one to see which one causes the issues again. I'm almost certainly sure that it is the widgets causing this at this point since this was a daily occurrence for me and since turning the widgets off I have not had the issue.

Before I even knew about the Bank widget causing these issues I had performed a hard reset my phone. Swapped it out for a new one, upgraded my phone and everything. Once I removed the widget boom issue was gone it’s been 2 weeks and no issues. I even went back to my iphone6s as the only reason I upgraded was bc of this. I returned the X.

Go to Settings-General-Reset and reset all settings.

Turning off bold text under Display and Brightness settings fixed it for me.

I think I found what caused this bug. Try turning off the "raise to wake" function. After disable, the info from the lockscreen did not disappear for two days.

What solved this issue for me was switching my lock screen wallpaper from “perspective” to “still” under wallpaper in settings. It’s been about a week with no issues!

This Worked for me:

Settings -> Dispay & Brightness -> Bold Text (Toggle on then Back off)

Version: 11.2.1

Model: Iphone x

Okay, I can confirm that it is the widgets causing the error. Typically certain banking widgets. Delete each one until you find the culprit.

Bug fix in iOS 11.3: “Resolves an issue that could cause time and notifications to disappear from the Lock Screen”

Could this finally be it?

I've had this issue since iOS 11 as well on my iphone 7+ and now iPhone X. The only thing that resolved it for me (so far) is not allowing notifications on my lock screen. I also disallowed notifications in history as well since this seemed to be related. It's an annoying fix but it's less annoying than seeing a blank screen 75% of the time I look at my phone... Hopefully a fix will come out soon.

Had this same issue on a 6S after upgrading to iOS11. Followed me to a new 8+.

I switched my lock screen wallpaper and went 4 days without a touchscreen lockup or clock disappearance. Switched back to the original lock screen pic and the clock was gone within 6 hours. My home screen wallpaper is one of the Apple supplied ones.

The picture I was using was one I took with a separate camera and have backed up in iCloud. Now using a different pic from the same photo session.

Hi all,

After 18 days from my last post, I can confirm that this has to be an issue set off by the background photo (wall paper).

I have had the simple black background provided by Apple all this time and not had a recurrence of the fault in question whilst using the phone with the two latest IOS updates.

One day recently, I changed the background photo to a personal one. Within 6 hours the fault appeared, this time more extreme as it would not let me unlock my phone. A restart was required.

UPDATE: 15 days and no problems with the clock disappearing on the locked screen. I eliminated all widgets (I don’t care about that function at all) and I’ve not lost the clock in 16 days. I’m done with playing with this. I’m leaving as is as I’m not missing any functionality.

Have you tried disabling any banking widget, especially the Discover Card widget? I removed my Discover widget on 11/21 and it hasn’t happened since. I was resetting my phone up to 5 times per day prior to that.
