Default Explain Knox to a simpleton

I am trying to get my head around Knox, its effect on my everyday use etc.
I do not intend to root my phone or anything like that.

The various posting in respect of this subject go above my head.

Do I understand that it creates a space on your phone where everything in that space is protected?

Whereas I am assured on this forum that it has been downloaded and I accept that statement (having little knowledge in this respect) Why am I presented by the fact that if I click on the Knox icon I am presented with ...”You need to download and install this app”

If I click on one of my apps, say - Lookout, I am able to access Lookout and sync it with my PC despite a message coming up "Security information. An application attempted to access system on your device without authorisation. This has been blocked"

Lookout has not seemingly been blocked?

Could someone explain in the simplest terms as to the situation.
I apologise in advance due to MY advancing years.

Very useful link. Thanks for the share. While I had rough idea about Knox, this surely cleared up all the little doubts I had about it.

cheers

Your links confirmed my understanding of Knox and I thank you for that.

However If I click on Lookout and also Evernote, I am able to access Lookout, EverNote and sync them with my PC despite a message coming up "Security information An application attempted to access system on your device without authorisation. This has been blocked".

Neither Lookout or Evernote were seemingly been blocked as the changes that were made were there and were synced.

Can't get my head round that part of it?

This is an overly simplistic explanation wunay, as requested.

(Quotes are from my previous link... What is Samsung Knox?)

#1. The latest Android firmwares contain the basic components, Knox flag and locked bootloader, to allow the installation and monitoring of the Knox security app.

"Knox does not come pre-installed on your Samsung handset, but there is a shortcut within the app tray so that you can download it (for free) if you wish to use it."

#2. Knox security is designed for those who use their phones at work or BYOD, Bring Your Own Device, where such places of work, i.e. GCHQ, NSA, Defence, Government, corporate business, etc, etc; demand a higher sense of security from the phones carried by their employees and means that one device can be used for both personal and work life rather than carrying around 2 phones, one for personal use and one for business...

"It helps you to securely separate your personal and professional data. Essentially, you can have the benefits of using a ‘work phone’ without the need to carry, and secure, a separate device."

#3. For those whose workplace demand such security, you need to download and install the Samsung Knox app, which you have done, and this effectively splits your phone in two. One half is for your personal life and carries few restrictions. The other half is for the more secure work environment and all things are monitored and permissions are needed. These are set and monitored by your organisations IT department. In this, Knox, section of the phone, restrictions are placed and can be altered or amended by your employers IT department...

"When in Knox mode, there are only certain apps that you can use. If Knox is installed by an administrator at your place of work, they will be able to specify which apps you can use. By default, the apps included are camera, gallery, downloads, email, s planner, my files, phone, contacts and internet. You do not have access to the Play Store, but there are an additional 75 ‘Samsung Knox’ apps that are available for download.

Certain functions are disabled within Knox, such as capturing a screen shot. Device administrators can also specify which apps can be used as sharing intents from within Knox.
"

#4. You are able to switch between Knox and personal mode, as described..

"You can switch between Knox mode and personal mode using shortcuts in the app tray and notification tray."

#5. Essentially, whatever happens in each mode, personal or Knox, stays within those areas and is not accessible from each other, by-and-large. The Knox section of the phone is controlled by your work place IT department who can change or delete data at will. They cannot access your personal section though...

"This means that if for any reason your place of work feels the need to remotely delete your data, it will only be applied to the Knox container and will not delete files in your personal account."

#6. If you have any problems with the Knox app then I would recommend contacting your IT department in the first instance as they will be able to sort out and explain any issues.

#7. Should you no longer require the enhanced security that the Knox app offers, (you change jobs, retire, etc: ), Knox can be uninstalled, as per the link, although the Knox flag and locked bootloader will remain as they are built in to the firmware.

Thanks for that. I do now grasp as to Knox after your earlier postings and forgive me for my persistence but why does the message come up "Security information. An application attempted to access system on your device without authorisation. This has been blocked" when the only apps used were Lookout and/or EverNote have not seemingly been blocked?

Again I apologise but I do keep going until I totally grasp the situation. I do not believe in stating I do understand when I do not.

As per #6, I would suggest contacting your IT department regarding this as they are in control of permissions.

So, why do you need to even use Knox Security on your phone?

I don't. It came with V4.3 and as I said I have not knowingly activated it, as it is asking me still to download and install. That is why puzzled.

In that case, I would recommend uninstalling it.

I think the problem is that, like me, Knox seems to be creating these security warnings despite it not only not being configured it hasn't even been installed apparently.

I accepted the automatic upgrade on my phone and have been getting these warnings ever since. I have a new shiny Knox icon in my apps list which is a shortcut to download and install Knox. It clearly has something preinstalled and configured as part of the upgrade.

Looking at other forums this seems to be something Samsung has been aware of for a little while as people with rooted phones have been downloading this upgrade early and reporting this problem so it seems pretty poor show that Samsung should deliberately release this known bug to everyone.

I don't really want to have to do anything complicated to my phone - uninstalling Knox seems to involve hunting for and deleting files which I don't really want to do in case I break something else, and I am not even sure I have it installed anyway!

Exactly!

To uninstall Knox you apparently have to go to the Knox Home screen to uninstall. But if you do not have Knox installed but merely waiting for you to install it how can you uninstall it?

The update to Knox enabled firmware, as per #1 in post #5, seems to trigger the Security notification. This is not an app but a part of the firmware that is prerequisite for installing the Knox app. In other posts on this forum and elsewhere on the web, it is reported that a Factory Data Reset can cure this problem as well as other suggested fixes.

That link you posted was the one that I had already seen but that would seem to presuppose that Knox is installed. The only reference that I have to Knox on my S4 is the shortcut to Knox which takes me to the "You need to download and install this app"!
Does that mean that I have to install Knox and THEN uninstall it?

There are no options to remove the Knox shortcut that I can see.

I appreciate your forbearance in this.

Can we be clear here wunay, have you downloaded and installed the Knox app, not the firmware?

All I have done is to update from V4.2 to V4.3 and absolutely nothing else.

The only reference that I have that Knox exists is a short cut to INSTALL Knox.

Despite that there are warnings given "Security information An application attempted to access system on your device without authorisation. This has been blocked".
.................................................. .................................................. .......
I have in the last twenty minutes spoken with Samsung, who using SmartTutor (remote control) went through my phone setup but could not understand as to what was wrong and could not explain or remove the shortcut to Knox. Samsung also witnessed the warnings after EverNote and Lookout were accessed.
We went into Security/Unknown sources and unchecked and then rechecked that entry and this has been the only change or adjustment to the setup.
Apart from that to all intents and purpose the S4 is the same as it was before Samsung viewed it.

BUT................. the warnings have not reappeared and Samsung are unable to explain the reason for that.
I am content in that the warnings are no longer in evidence but thought that I would provide the above in case others may benefit or explain as to the cause of the problem.

I still have the Knox shortcut though.

I think Samsung is mismarketing Knox horribly! Instead of personal/work they should be marketing it as normal/porn.

OK. Thanks wunay! My bad then as it appeared to me that you had installed the Knox user app. In that case, disregard my posts after #5 and put it down to a lack of alcohol.

Quote:

That installs the Knox user app, if available, so disregard that or, alternatively, install a custom launcher such as APEX or Nova from the Play Store and select to hide that app in the app drawer.

Quote:

As per my reply to to fumblina in post #14, you were receiving these warnings because of the firmware that contains Knox components and not because of the app installation...

Lets hope it stays that way or you could try a reset.

That comes as standard with the Knox firmware.
