Guided Access disable screen sleep

I think I may have found the solution.

Go to settings > General > Accessibility > Guided Access

Once there at the bottom there is a mirror display auto lock. Make sure that is on. I was struggling with this and just found this setting.

Hope this helps,

Nik

I'm having the same trouble as nrathbun. I have an app I run in Guided Access in a public space and I want to keep the screen from sleeping. I checked all the settings for Display & Brightness, adjusted settings in Screen Time, even turning it on and off with the same result. I also tested on a different model of iPad running iOS 12. After checking this forum I reinstalled the operating system as per becky_s22's suggestion and still have the same result, the screen sleeps after 10-15 minutes but does not lock the iPad as a home button press wakes the screen and I'm still in the app in guided access mode. This appears to be an issue with iOS 12 as I have other iPads running iOS 11 in guided access with no problems. Any information/suggestions would be appreciated.

Thanks.

Greetings, nrathbun.

I see that you've set up your company's iPad devices using Guided Access. The problem is, after updating them to iOS 12, the lock screen had been engaged after you left them on overnight, and you'd like for this to stop. I'm happy to help.

Adjust the brightness on your iPhone, iPad, or iPod touch -- Go to Settings > Display & Brightness > Auto-lock, and set that to "Never".

Take care!

Thanks for getting back to us, nrathbun. It's appreciated. I'd like for you to select one of the iPad devices to reinstall the operating system.

Let me know how that goes, and cheers!

If you’re using iOS version 12.1.1 or above, you will want to turn on the Mirror Display Auto-Lock

• Under Guided Access, turn on Mirror Display Auto-Lock.
  • When this is on, Guided Access will mirror the Auto-Lock setting in Display & Brightness. When off, Guided Access will turn off the screen after 20 minutes of inactivity.

Same boat, here too.

We got a number of Ipads as part of parking machines, to charge for cars, boats, and mobile homes.

The screens are now turning black after a little while, which makes people believe that the system is down, resulting in substantial financial losses.

We are now considering reverting to the use of small Window-based Pc's again.

PS. We have 243 parking machines in operation, and another 200+ on order, so this is not good for Apple.

I really hope a fix is in place within 1-2 weeks. Anything else would mean a final goodbye to the i-world.

We're suffering the same problem on our 4 iOS 12 stationary devices that we've upgraded. Using Zoom and Teem, seeing these effects on iPads with either app on it, so we know it's not the individual apps but something from iOS 12 that's causing it.

Hello,

Just wondering if the most recent update to iOS 12 addressed this issue. I haven't tested it yet, but was hoping someone else might have. I continue to have these problems as well, and it is causing a lot of frustration. What's the use of having a device for kiosk use, if it keeps going to sleep

Can confirm this is also the case. Display remains on (it has at least all morning with our testing) if Guided Access is turned off. Although that kind of defeats the purpose because we want to lock that app into place. Our Apple SE is also taking a look at it.

One other thing I noticed when Guided Access was on and the screen fell asleep, I woke it back up and saw the Home screen where the app that I wanted locked into place was getting Cleaned. May be related.

Guided Access mode off all day has definitely kept our displays on, can confirm the issue is somewhere present there in iOS 12. Our SE seemed to indicate to manage around this in our MDM by removing/disabling all other apps and functions and abandoning Guided Access or Single App Mode as Apple does not love either feature. Take that for what you will, hopefully they will actually fix the problem though, so flex your muscle elsewhere if this is a problem for you and you have some pull with Apple.

One solution that I have heard is to revert back to iOS 11.3, but that would be quite time consuming with the number of devices you have.

We figured out a 'fix' for our app - see here -> https://flowkiosk.com/guided-access-bug-in-ios-12-fixed/ - I'm sure there is a way to fix your current software.

Thanks and good luck!

This turned out to revert to not working within 24 hours. My new fix was to add to DEP as a supervised device in Meraki and utilize single application mode. I guess guided access is done until Apple fixes IOS 12.

Same problem here, Since the IOS 12 update my iPads used for business purposes set in Guided Acces fall out in sleep mode after certain time. When not set in Guided Acces iPad stays on unlimited. Tested with app that I use for business, but also with Apple native app like mail. Problem seems really to be in Guided Acces in combination with IOS 12.

APPLE PLEASE FIX THIS BUG ASAP!!!

I'm having the same issue. We have several iPads locked down with Guided Access in a museum setting so visitors don't mess around with them. They are now going dim. I've tried removing the access code, and turning off screen time. We have to have guided access to keep the display on the correct application, otherwise visitors play around and get back to the home screen.
