The reason behind this "strange" behaviour with KNOX is... human incompetence.

The flag triggers only after flashing something that isn't considered "official". That is in conflict with the usage policy and therefore voids the warranty.

However, most of the time the people who accept the phone don't even know about this hidden counter - and it is hidden for their incompetent eyes, believe me. So they accept the phone, maybe check in Settings if device status is "Official" and then send it to the repair centre with a note attached that says - good to go. The technician no doubt has a ton of handsets to fix so wouldn't even care to check every single one. And other times the phone is so bricked it would need a board replacement - hence the KNOX "reset".

So - does KNOX void warranty? - It does. But in the end it's people who determine if the phone gets repaired or not - so there is a pretty good chance you'll get lucky. :)

Whatever you said is right but then again what if i dont need knox we dont have a choice. Why do i buy android because i like having options. Theres no point locking out users if that were the case i would buy Windows phone 7 or iphone for that matter. I really feel its good that knox is not voiding warranty otherwise i would be forced to use samsung stock rom for at least 1 year in warranty with limitations like 9gb only for games, limited apps in multiwindows no camera at low battery and what not. Google should have a policy for all android OEMS to have all software open for most phones and if business need then they can brand it seperately so we can enjoy android. In my case i bought a nexus 5 and might sell s4 anytime and will never buy a exynos device despite my love for TW and superamoled screens. PEACE

Just learned about the knox-flag a few days after rooting my device, typical! Should have done more research, but done is done so I contacted the Swedish Samsung Support for more info, just in case I need to return my phone some day:

Translation to English:

So if we unroot and use triangle away we should in most cases be fine. I can't really see them checking the knox flag on every device.
[Galaxy S 4 General] tx12345:
Australia here. Phone was in for a clear hardware fault but Samsung Australia have decided that warranty is now void as a result of rooting the phone. Knox wasn't mentioned but must have been the culprit as phone was restored to a stock ROM with ODIN (and Device Status is back to Official).

Not happy as they have chosen to use that as a way to deny warranty insisting that rooting has damaged the phone. Unless someone finds a way to restore Knox I'll probably steer clear of Samsung in the future.
[Galaxy S 4 General] leyton01:
Did they tell you why they thought it was rooted?

From what I have read KNOX can be tripped through doing non-root (ie samsung only firmware downgrade) and you could argue that. Unless they can prove it has been rooted I think your warranty rights as a consumer can't be denied.
[Galaxy S 4 General] Smirftsch:
I didn't get an answer yet here from Samsung Germany, but I think the conclusion of all this topic here is rather obvious.

Does Knox void warrenty? If you read the warranty policies from Samsung, the clear and not deniable answer is indeed absolutely clear: NO

BUT!!, it does imply almost for sure that you violated the policies by rooting etc, which again clearly voids warranty.

Or to rephrase it a bit- the problem is not the Knox flag, but what it means.

So in theory they would have to replace a phone with original software but Knox 0x1 (I read already some cases in which people claimed that Kies did this, no idea if true), but they could deny it any time with Knox 0x1, stating you caused the problem yourself and aside this you know there can a lot of cases in which you can't reset your phone back to original software before sending back if damaged. So there is a certain risk in any way.

In the end I think they probably will replace it in cases which are definitely not software related and if it is only to avoid trouble with lawyers around the world, but not more. Anything beyond that is maybe luck and nothing to bet on it.

Also I entirely disagree here. It's nothing to argue about. There is no "Downgrade to 4.2.2" option in Kies, there is nothing you can do as end user, if you are experiencing trouble with 4.3 you have to rely on Samsung and their service.

An end user is not supposed to mess with Odin, not supposed to mess with downgrades or bootloaders etc etc etc. They even protect their Roms in kies when downloading new versions, you are not even supposed to have an older Rom to downgrade with!

It doesn't matter what you want to say to them, they don't need to prove you that you rooted your phone, they only need to know that you messed with it and therefor violated the rules- ironically you even admitted already in this moment that you violated them by trying to downgrade.

Unless OFFICIAL software like Kies was proven to be able triggering Knox there is absolutely nothing to argue about with Samsung.
[Galaxy S 4 General] idroid2324:
Thanks that really helped. :)
[Galaxy S 4 General] tx12345:
Yeah I probably can, but I'm honestly considering whether it'll be worth the hassle. I'm not happy with how I've been treated and at this stage I'm almost willing to let them win just to not have to deal with them anymore.
[Galaxy S 4 General] Aijazji:
They Accept My S4 for screen Replacment Without Any Issue..

Warrenty Bit 1

They check only official firmware..

So Knox doesnt void warrenty in INDIA..
[Galaxy S 4 General] trveller72:
lucky you

Very glad for you DjeMBeY - after all your work to have rooted firmwares, it was such a pity to have the Knox flag triggered.

Maybe the guy in the repair centre was using one of your firmwares and did not care the warranty:D;) was void
[Galaxy S 4 General] Gboss01:
I sent my i9500 in for proximity sensor issues.

Warranty bit 1

Lets see if they replace it for me.

I hope they do and I pray they have JB 4.2.2 loaded on it as well.

I'm never gonna upgrade it to 4.3 unless it CM10.2 or CM11.

I wanna keep my bootloader unlocked :)
[Galaxy S 4 General] jbakers:
What alot of Dutch people forget is that you can easily send the repair bill to your house insurance. (Inboedelverzekering)

Just take the phone to a local repairshop, pay the bill, and send the bill to your insurance company. NEVER send it to you official phone dealer, because you'll lose your phone for weeks, if not months.

I got both my previous S3 and my current S4 fixed this way, and in the end did'nt lose a dime.
[Galaxy S 4 General] SERBDVB:
i just call samsung canada and they told me that i have one year warranty despite knox trip 0:1.....so hope this will help...i'm with fido
[Galaxy S 4 General] rgshah3:

Got my cell back Display Is Changed bt they dont reset my knox counter..

I am Happy with brand new display :)
[Galaxy S 4 General] hypergamer1231:
Got some shocking news from samsung today..i was on mj9 latest 4.3 for india with warranty bit 1.....facing severe heat issues and battery drain....they took my phone and gave me a spare s4 to use till mine is fixed..........my phones motherboard and battery will be replaced...now the interesting part when i was there an audit by a high level samsung exec was under way...happened to speak to him...he said most high end samsung devices have a fuse or something if you root the device that fuse goes off and in the long run the phone will develop issues like random reboots and heat and battery drain...hence rooting is not recommeneded.......now i know it sounds like a joke but he seemed to know what he was saying.....Atleast am not rooting my s4 will analyse the heat and battery after i get it!!!!!!
[Galaxy S 4 General] rgshah3:
There is nothing like that! Rooting is just software related and doesn't affect the hardware in any manner
[Galaxy S 4 General] modyt:
I'm sure ab auditor surely won't know how hardware or software works. :D
[Galaxy S 4 General] louiscar:
If there's a shred of truth in that then the only conclusion is that they have deliberately simulated that fault in software.

For now I'd just take that as a veil for "Samsung don't like you rooting our devices" ... "our" being the operative word.

Soon I guess their phones will come with a license agreement or EULA - " Purchasing this phone does not give you ownership it just gives you a license to use it"
[Galaxy S 4 General] testadeferro:
EULA is equal ti 0. You can say in court That when You bought the phone you could nt read it. Its not outside te box nor in the box inside. Only when you use the phone for the first time. And then is a used phone.
[Galaxy S 4 General] gazmendf:
hi a like to bay a i9500 but if a root and make a knox 0x1 can a recive official update from kies, and does the phone will work or not am so confuse with this knox security
[Galaxy S 4 General] Gboss01:
Today I got a call from my service provider to say that my S4 has been repaired.

The mainboard has been replaced along with the proximity sensor.

They will be shipping the phone back to me and I should have it in my hands by Wednesday.

Warranty bit was 1 at the time I sent it in, so it seems Knox does not affect your warrantee in South Africa either

Happy Days :D
[Galaxy S 4 General] bungadudu:
The phone will work in pretty much the same way but you'll loose the warranty and ota updates.
[Galaxy S 4 General] rkaede:

[Galaxy S 4 General] acid123:
Uk as well taken my s4 in and my mate had his note 3 repaired,

Both had Knox 0.1,

Repaired and back too 0.0,

Still don't understand the point of Knox,

When I started the phone up after getting it back I got the security message saying app block, when I was setting it up from new,

But there was nothing on the phone totally fresh apart from samsung one apps, so even there own apps give warnings
[Galaxy S 4 General] gazmendf:
thanks man very mach its mean that with odin a can update to the last frimware
[Galaxy S 4 General] bungadudu:
Sure
[Galaxy S 4 General] apokotou1709:
Today I talked with Samsung Greece Support Live Chat. He Kept saying to me me that Knox 0x1 means that my warranty is Voided Because the Phone has been modified . Even though I tried to make him check more in case he was misinformed Nothing changed...
[Galaxy S 4 General] madk:
Warranty void with KNOX flag 0x1 in Greece. They have no clue in the Netherlands

I chatted with the Dutch support. They cannot answer about KNOX. As for the Greek support the translation is as follows:

It looks like indeed hardware tampering occurs and sets the flag, if you judge from their response.

Sorry guys at least in Greece...
[Galaxy S 4 General] hypergamer1231:
I can confirm here in india no one checks warranty bit on 9500 just got my s4 back and they have installed a new mobo and battery. They had installed 4.3 on the new motherboard I requested them that I need 4.2 as I dont like 4.3 and immediately downgraded the device to 4.2.2 with old bootloader. now am so happy i can flash all roms without worrying of knox ever. people in India at least can visit svc and ask them to downgrade to 4.2.2 and they will happily do that for u guys cheers
[Galaxy S 4 General] bungadudu:
If they're so eager to help ask them how to downgrade from home, for the ones who can't get to their shop but are unsatisfied with 4.3.
[Galaxy S 4 General] hypergamer1231:
Nah I asked him and he said we have the necessary tools and they are actually able to write imeis from the Samsung server so yeah they have the tools
[Galaxy S 4 General] Gboss01:
Finally got my S4 i9500 back today from repairs.

Before I sent it in my warranty bit was 1.

They have replaced the proximity sensor.

And the mainboard was replaced to fix the problem with the s-view clocks flashing at random.

The best part of the whole thing is my firmware is 4.2.2 and there's no warranty bit in Odin mode anymore.

I'm so happy, no Knox bootloader anymore. Already rooted and running Prism Barebones Rom :D

Knox warranty bit = 1 has no affect on warrantee in South Africa
[Galaxy S 4 General] rgshah3:
They are repairing phones just now because they don't know what this is exactly! After they are told, then our services will stop
[Galaxy S 4 General] testadeferro:
Tell him that he's not above EU warranty rules. And you can also acuse Samsung of use of spywares. In last case you can always say that when you bought phone the EULA wasn't to read nor outside the box or inside the box. To read and agree with terms and conditions you must purchase the phone open it use it and when you disagree you couldn't send back. That's reality and 3 great things that they could not voiding warranty in europe. Open your eyes. I discussed this with Samsung Portugal and they full agree and told of the record that this is a try.
[Galaxy S 4 General] t0pg3ar:
Dutch guy coming in here. I also opened a support chat with Samsung. I won't annoy you with a Dutch conversation. I will give you the summary:

"Hello. If my Knox bootloader's tripped, do I keep my warranty? Blabla EU blabla..."

"Yes, you will keep your warranty, but only on the hardware. If you brick it/destroy the software we will not help you."

In other words: You keep hardware warranty, lose software warranty. Nice to have that clear now.
[Galaxy S 4 General] bungadudu:
That is the most reasonable answer! :thumbup:

[Galaxy S 4 General] WolfSpider95:
Looks like the warranty (in the United States) is still in good standing if something hardware related decides to fail.
[Galaxy S 4 General] rgshah3:
That's the perfect answer!
[Galaxy S 4 General] broodplank1337:
I have something to tell you guys

Mod Edit swearing removed

Luckily I never touched one of their new disgusting bootloaders infected with the Knox parasite.

But let's be realistic, Samsung is one of the wealthiest multi nationals on the entire planet, and they usually hit the new record for most profit, and then they STILL want to take away your warranty over nothing, to earn even more money on top of the 600 euro you already spent for the device that they infected with the touchwiz, knox and bloatware parasites and expect you keep their junk.

If you think about it it's just RIDICULOUS

I mean I like samsung for it's hardware but that's all, I always hate their software, time after time

New Smartphone (i9505) comes with a stock rom where 3 sensors are not working, and a benchmark directly triggers MASSIVE OVERHEAT (100 degrees celcius, no joke, in 2 seconds)

New Smart TV, last generation, Very laggy and bloated firmware......

Samsung, please stop making your own devices suck by adding your favorite parasites.............

Ok i'm done now hahaha. that's a relief :laugh:

My next device will be the next Nexus I think :D

About rooting Samsung KNOX-enabled devices and the KNOX warranty void bit

"When it comes to rooting, there have been some questions regarding Samsung’s KNOX-enabled devices and if they can, or should, be rooted at all. From Samsung’s perspective, the short answer is yes, but it is important to take into account the end user’s situation since device rooting should be evaluated on a case-by-case basis due to conflicting requirements. For example, enterprise users and many individual users rely on the integrity and security of Samsung software, particularly the boot loaders and the OS kernel, yet they may want the choice to put a non-Samsung OS on their Samsung phones.

Samsung KNOX brings a new approach to address these conflicting requirements. Specifically, KNOX-enabled devices use the trusted boot to measure the boot loaders, the OS kernel, and the initial scripts and data used by the kernel which are stored in the TrustZone secure world with proper security protection. KNOX-enabled devices allow a customized OS kernel to boot which allows individuals to run customized Android systems. (Note: when required by carriers, KNOX-enabled devices use kernel lock to prevent customized kernel images from booting.)

However, when an enterprise user needs to create or use KNOX Containers to protect enterprise apps and data, the KNOX-enabled device verifies whether a customized boot loader or OS kernel has ever run on the device. KNOX will stop offering container services when it can no longer provide the same security protection for enterprise data due to the previous installation of a non-KNOX OS.

To further illustrate how this works, the “KNOX Warranty Void” bit (or simply KNOX bit) is used to detect if a non-KNOX kernel has been loaded on the device. It is a one-time programmable bit in e-fuse, which can only be turned from “0” to “1” (i.e. burned). If a non-KNOX boot loader or kernel has been put on the device, KNOX can no longer guarantee the security of the KNOX Container. As a result, this KNOX bit will be burned to “1”, indicating that this device can no longer use the KNOX Container service. There are two possible scenarios: first, a new KNOX Container can no longer be created on such a device; and second, the data encrypted and stored in an existing KNOX Container can no longer be retrieved. Everything else should work just as before.

As final note, it is possible to damage the device if the system software is not written properly. For example, system software can potentially overwrite the hardware configuration data stored in e-fuse and render the device completely irrecoverable. "

My S4 started freezing in deep sleep and no way to fix it.

I just told them that and they fixed it without asking.

I was running stock Touchwiz so I could say that it started freezing after I updated the phone as an excuse just in case
[Galaxy S 4 General] finity69x2:
You left off the last, but most important, line from the above source:

" Always check your warranty coverage with your device reseller or mobile service operator. Many will void your warranty if your device has been rooted."

Sounds like it's "OK" with samsung if the device is rooted but the repairer may not like it. Or maybe it's just a way for samsung to put the responsibility for being the bad guy onto "the other guy".

Don't worry, they will replace it for you. Anyway samsung has confirmed the problem with a production's series of battery and invited anyone experienced that problem for a free replacement even if the warranty of the battery (3 months in my case) is no more available.

From singapore, the samsung service centre told me to pay for my note 3 repair altho my phone was less than a mnth old,based on the Knox 0x1

had to put up a fight to get it fixed without paying

what seems funny is that almost all the ppl who came to collect their phones, seem to have had their motherboards replaced no mater what the problem was, including mine

the tech told me the knox 0x1 cant be reset juz by reflashing the software and all they seem to do is juz replace tons of mother boards,

dont know if they're juz bluffing

Edit: Same goes for my N7105, tripped knox after 4.3 update, motherboard replaced, so they claimed
