Blinking screen while lockdown is on - Mobicontrol

Blinking screen while lockdown is on - Mobicontrol

Hello,

I have a problem with propably lockdown ( Soti Mobicontrol ). When the lockdown is on, screen is blinking every a few minutes. It is look like lockdown want to reload/refresh.

I removed all external links (for example JS/CSS/Img files ) and files reference from lockdown, because I thought that files refreshed and then reloaded lockdown.

I don't idea where is the problem.. Without lockdown, it works well.

Maybe this issue appear when the devices lost connection to the internet and then connect? Then the lockdown try to reload screen or something.

 

Agent: 13.9.0.1046

Device: Zebra TC56

OS: Android 7.1.2

Do the blinkings happen at REGULAR intervals for all problematic devices?  If so, what is the approximate interval?

Are there blinkings for ALL enrolled devices with lockdown deployed? Or only for SOME of your Zebra TC56 device(s) ?

Hello Raymond, thanks for responding.

All enrolled devices with lockdown have this problem, but not every day.

The screen is blinking during using applications ( all application which we have on lockdown ). Blinkings usually stop after a few hours, but not always. I think when we restart the device it's worse.

This problem looks like pressing the Home button several times. Then an employee can't press anything for a moment, because lockdown is reloading.

Have you tried using different device agent version(s) and see if the same problem persists?

How did you define your kiosk items (e.g. using launch:// or something else?) for the application(s) running with blinking problem?

I have not tried using different version, because we had problems with former versions Mobi Agent - for example we couldn't open our main app to work. Do you think that it can be a problem?

I define kiosk items by: Launch:// to open apps and https:// to open www in kiosk mode.

Hello Michal,

 

Thank you for performing quick test, please perform one more test to move ahead

As you mentioned this issue is happening on few devices, please change network connectivity of the device for example if it on WiFi changed it to cellular if not change it to cellular hotspot.

And let me know the behavior of the device.

Hello,

I will check it tomorrow.

Has Mobicontrol any extended logs? Maybe this issue is described in logs.

Hi Michal,

Are you using the standard html/CSS lockdown template or a very customized version? 

Have you tried deploying the same MDM policies to test device brands/models other than TC56 and see if you get the same problem?

Hello,

Sorry, that I haven't answered you.

JVMOD@SOTI, we were testing your solution, but it's still not working :(

I checked Samsung Tab and this device has the same problem. I used the same policies like in TC56.

 

We are testing the latest OS Android ( 9.0 ) on tablet and I think the problem not appear now.

But I heard that TC56 don't have newer OS than 7.1.1 :(

 

We are looking a few next days, that the problem is still appear on tablets.

 

Maybe you have other solutions?
