"KnoxSandbox", a small Samsung system component with no published description. It is OEM platform-signed, has no launcher icon and is never user-facing in our sample. At roughly 1.1 MB it is far smaller than the two Knox components it ships alongside, and it declares only internet and network state access plus its own dynamic receiver permission. That permission set is too thin to infer a function from, and Samsung documents no package by this name, so no functional claim is made here and no safe_to_disable rating is given. Two observations are worth recording because they are the useful part. It arrived in this database on the same date as com.samsung.android.knox.knnr and com.samsung.android.knox.kfbp, has always been seen on the same devices, and shares their version line, reaching 1.3.01 in step with them. That is circumstantial evidence of one family rather than proof, and it is the reason the three are documented together. Separately, the word "sandbox" is used for several different things in Samsung's published material, including the isolation of third-party apps under Separated Apps, so the name should not be read as identifying any particular Knox feature. For Android Enterprise, EMM and kiosk deployments it has no role in enrolment or policy and shows the user nothing. There is no functional gain from removing it and no sourced basis for judging the cost of doing so, so the sensible position is to leave it in place and treat it as undocumented vendor platform code. Version note: first recorded in June 2025 and seen only on devices reporting API 35, 36 and 37, that is Android 15 and later. Builds run from version 1.0.09 to 1.3.01 with target SDKs of 35 to 37. Whether it exists on earlier One UI releases could not be sourced.

Package intelligence

Observed signing, permission, version and size signals from contributing devices - descriptive of that sample, not a verdict. These come from the v2 Package Search sync, which not every device has contributed to yet, so for some packages this detail is partial or not present at all.

Declared permissions (3)

Largest permission set observed for this package. Text is Android's own published description where one exists; platform permissions Android does not document show their granted protection level (in grey) instead; vendor or unknown constants show the name only.

PermissionDescription
ACCESS_NETWORK_STATE Allows the app to view information about network connections such as which networks exist and are connected.
INTERNET Allows the app to create network sockets and use custom network protocols. The browser and other applications provide means to send data to the internet, so this permission is not required to send data to the internet.

Manage on devices

ADB commands for this package (the inverse of each is included so you can undo). Run from an authorised shell or wire the equivalent into your DPC. Verify on a test device first - this database doesn’t yet classify which packages are safe to change. --user 0 targets the current user; drop it (and use a privileged shell) to act device-wide.

Disable for the current user
adb shell pm disable-user --user 0 com.samsung.android.knox.sandbox
Remove for the current user - a per-user uninstall; the APK stays on /system, so Restore re-adds it (-k keeps app data)
adb shell pm uninstall -k --user 0 com.samsung.android.knox.sandbox
Re-enable
adb shell pm enable com.samsung.android.knox.sandbox
Restore (re-install for the current user)
adb shell pm install-existing com.samsung.android.knox.sandbox

Each record is a device profile (make + model + Android version). Each unique handset that syncs against a matching profile will increase the observations of a package, thereby increasing confidence that a package is expected to be on a device.
