Make sure you have the setting "Install applications from unknown sources" turned off. Samsung disables many security features when that setting is turned on. On the S8/S8+ this can be found in settings > lock screen and security > install unknown apps | then turn everything to not allowed.

The problem is these KNOX phones are finicky about what you install, nor is Samsung open about exact triggers. Go into download mode and check for the 0x1 (KNOX warranty void) bit as a quick check to see how much of a waste of time troubleshooting is. 0x1 means KNOX is never, ever going to work - along with related functions (Health, KNOX folders, probably Samsung Pay). The problem with their secrecy is if you installed something was installed that tripped the fuse since it messed with the OS, it’s a black box so you can’t figure it out and prevent it on others devices since it’s an eFuse. GENERALLY, these are the “common” 0x1 triggers:

  • Custom ROM
  • OS downgrade
  • Bootloader replacement

If any of those were done, it’s an old trigger that was caught in a software update that was missed previously, sad to say. The problem is the status is spoofable in Android but not at the bootloader level.

A tripped KNOX flag doesn’t bother me because I do not care about the apps that get killed over the 0x1 trip, but it does affect WHO will buy your old phone if/when you sell. In addition, you won’t be able to trade it in through a carrier or many major resellers since it DOES matter to enterprise customers and they want to buy 0x0 (untampered) phones. The early KNOX phones (S4-S6/Note 2) was also easily triggered, but it didn’t matter since the S Health app wasn’t used for healthcare functions like it is now. For more people, it does cripple more of the phone beyond enterprise, so the resale damage is worse than it used to be. You also can't JTAG it back to 0x0 anymore - that hole was closed with the baked in KNOX phones, sadly. It was also possible to do a binary reset but that only worked on a subset of phones - the JTAG method was better at the time then the binary reset method. All of this because Samsung refuses to “lock out” the healthcare function, which is JUST AS DAMAGING as the full lockout since people who rely on it will still not want your “custom” phone - yes, they WILL check - or have someone who knows how to check.

Refer to this guide to get the phone into download mode. This link also has information on how to do it if the first link is not helpful. Once you know if it says Samsung Official or Custom, you at least know where you stand. If you see 0x0 and Samsung Official, your best bet is to clear the data from the apps that use KNOX, downgrade and disable and then run the updates again.

Charlie, I would also be interested in your reasoning. Just posting a down vote with no reasoning behind it helps no one.

If you're too lazy for a long process, uninstall your s health app, download a lower version of your s health app from an apk site (virus free), update it!
