Samsung Galaxy S6 Forum

I can't deactivate this Device Administrator

I've attached a screenshot:

The deactivate option is just greyed out so I can't click on it, which means I can't uninstall this stupid app.
It's a Samsung Galaxy S6 and it says the model number is SM-G920F.
Can someone help please- I don't want to be forced to do a factory reset...

Cheers Droid. deactivate grayed out.png

Well what app is that? If that app was preinstalled, even a factory reset won't remove it.

The app is called MaaS360. It was not preinstalled- it was an app I was asked to install so I could receive courier deliveries throught it (that's my part time job- courier)

You may need to reboot into safe mode and remove administrator privileges there.
The google machine tells me the steps for safe mode on your phone are below. :)
  1. Turn the device off.
  2. Press and hold the Power key.
  3. When "Samsung Galaxy S6 edge+" appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.

The MaaS360 app the managed client for the IBM mobile security package. You may need to get your account administrator to drop your device from the managed list before you can remove it.

Go into <Settings> then scroll down to <G> app then look for connected apps and there you can deactivate any apps that's connected to your device then you can remove device administrator. Note: When installing certain apps is good to read the permissions before you install them because some are designed to manage our device's Administration

But how does the account administrator know what my specific device is?

<G> app ?? What is that?
#8 Droideka95, May 16, 2018
G Google apps

That would depend on who set it up and how it was identified when it was registered with the system. The common way is by a company domain login or email address. I would guess if you requested the removal, they'd know which device is yours.

I don't know all the idiosyncrasies of MaaS360. We've only just implemented it for fleet management and I was only part of the installation team. Our dispatcher and fleet manager are the ones who use it daily.

But there are so many things in "Connected Apps" such as Android device, Drivetunes, Google Chrome, Whatsapp, Yahoo!, iOS.... etc- which ones do I disconnect and why? What if there are some which are meant to be connected- I don't want to create further problems by disconnecting something which I'm not supposed to...

I'm going to email the guy I think controls it now...

All the ones that's in your connected apps are apps you have given permissions for. Yahoo and apps such as that are strictly preferred apps that you want to have connected but not necessarily need because you can access Yahoo from your web browser. Whatsapp is not a systems app also. But what's the most important go into your settings and look for the Device Administrator apps and look and find out which app has that permission and disconnect that particular app. I was giving you a location on where to look and see what's going on with the apps on your device you can pick and choose which ones that you don't want as long as neither of them are Android device manager or Googles.

This is really all you need but anything outside of these are mostly games or social media apps that you have connected to your device one of which is and has became your device administrator.
#14 KBU2, May 16, 2018
I've noticed you have iOS as one in your description. Are you running iOS on your device also?
#15 KBU2, May 16, 2018
Bingo. I clicked Remove MDM control inside the MaaS360 app and when I checked the list of Device Administrators the tick was automatically gone and it let me uninstall. Thanks for everybodys input :) Much appreciated.
