@usermMxl4ws2RT What type of device are you using?
On my Note 8, whenever I unlock my phone secure folder automatically opens without authentication, I have tried several times searching how to fix this bug but I didn't find any solution. Kindly help me to fix this error.
I have buy a used Samsung S7 Edge.
Device Status: Official
Rooted status: Not Rooted.
Can't create Secure folder or start Samsung Health.
How to see if the phone has been rooted:
If the phone has not been rooted in the past: 0 (0x0000)
If the phone HAS been rooted in the past: 1 ( 0x0400)
If that is the case, there is no way to revert the Warranty Bit and Knox won't work on this device. The only way to get the device back to its original settings is to replace the PBA (Printed Board Assembly) on the device; hardware replacement will be required.
