No—using Samsung’s supported Find My Mobile remote screen-unlock feature is not described in the cited Samsung materials as voiding a tablet warranty or triggering the Knox Warranty Bit. It is different from unlocking the bootloader, rooting the tablet, or installing unofficial software. A warranty decision still depends on the tablet’s purchase region, applicable terms, and the cause of the fault.
What “Find My Mobile unlock” means
Here, “unlock” means regaining access to the tablet’s screen or resetting its screen-unlock method. Samsung support describes using Find My Mobile for that purpose, including resetting a PIN, pattern, or password when the owner can still access the device biometrically. The feature must have been activated, and availability and steps can vary by model and software version. Samsung UK’s instructions and Samsung’s feature guidance explain the supported screen-access operation.

That is not the same as bootloader unlocking, rooting, modifying the kernel, or installing unofficial firmware. The cited Samsung Knox materials discuss those software changes—not the supported remote screen-unlock feature.
What Samsung says about Knox and modified software
Samsung Knox documentation says the Knox Warranty Bit can change when an older or unofficial Android build is installed. Samsung’s Knox Security Whitepaper states: “If the kernel has been modified, Trusted Boot sets the Knox warranty violation fuse.” Samsung Knox Platform for Enterprise technical overview and the Knox Security Whitepaper describe these security consequences.

A set Knox Warranty Bit does not necessarily stop the tablet from working, but Knox-dependent functions may be blocked. This evidence concerns unofficial software or kernel modification; it does not establish that using Find My Mobile to regain screen access changes the bit.
Why the warranty answer depends on region and fault
There is no universal warranty outcome to infer from this question alone. Warranty terms depend on the tablet, its purchase country, and the reported problem. Samsung Philippines, for example, lists damage or defects resulting from unauthorized software or root access among its exclusions; that is Philippines-specific wording, not a global rule. Check the terms that apply to your tablet and purchase region. Samsung Philippines warranty information and Samsung US warranty information illustrate why regional terms matter.

What to do next
- If you only used remote screen unlock: distinguish that action from bootloader unlocking or software modification when describing the issue to Samsung or an authorized service provider.
- If you also modified the software: disclose any rooting, unofficial firmware, or kernel changes. Those are the actions Samsung’s Knox material associates with security consequences.
- Check coverage for your exact tablet: identify its model and purchase country, then review the applicable warranty terms. Samsung US says eligible Galaxy owners can view warranty coverage and expiration in the device’s Warranty and care settings when it is linked to a Samsung account; availability varies by region, model, and software.
- Ask about the specific fault: contact Samsung or an authorized service provider with the model, purchase region, and symptoms. Only they can assess the individual claim under the applicable terms.
