Samsung Knox for Haat Partner +

KME: Knox Mobile Enrollment. APK: Android app installation file. Fully managed: the organization manages the whole business device. Kiosk: a restricted screen with only approved app access. Track: a separate release/testing channel. versionCode: Android's numeric app-version counter.

New console: open Devices > select tablet > LIBRARY > Apps > INSTALLED APPS > ACTIONS > Install or update in-house app. The app-detail device list also documents Install app and Push app actions.

For a replacement binary, update the app package first. Samsung's Original console procedure is Application > Modify > upload newer APK > save > reassign to the target group. Do not mix the two consoles' menu paths.

This is a direct management action, not waiting for Google Play to publish that APK.

No. A consumer Play Store auto-update switch does not distribute a file sitting in Knox Manage. For a direct APK, Haat supplies the newer package and triggers its managed deployment. For a Play app, Haat publishes a release, makes it available to the intended track/devices and sets the managed update policy.

Even a private app uploaded through the embedded Google Play window is still Play-distributed, not the in-house APK route. A saved draft in Play Console is not a published update.

Not casually. Updates need compatible package identity and signing. With Play App Signing, the upload key may differ from the app-signing key on the installed app. A locally signed APK may therefore fail to replace the Play build.

A compatible Play release may also update an installation from another source when Google's eligibility conditions are met. Haat should select and test one controlled update route per device cohort; switching channels needs a migration test.

One restaurant: map that restaurant to its tablet and target that device or a one-device group where the chosen delivery path supports it. 10 selected restaurants: put those ten mapped tablets into a manual device group and assign/deploy to that group. Dynamic groups can automate membership only when supported group attributes match the rule Haat needs.

A native Knox Manage Android app-release percentage slider was not verified in the current Samsung documentation reviewed. A Haat-defined 10% wave is therefore a selected group, not Knox randomly choosing 10%.

Google Play staged rollout is different: Play can release an update to a percentage, but Google says users are selected randomly from the eligible audience. Use that when random percentage rollout is acceptable; do not describe it as “Restaurant A through J”.

Official documentation: Samsung: manage group members · Samsung: manual/dynamic groups · Google Play: staged rollouts

Selected businesses: yes, through their mapped device/group. For example, selecting 10 of 100 tablets is a Haat-defined 10% batch. A native automatic percentage rollout control in Knox Manage was not verified in the reviewed Samsung docs.

Google Play staged rollout does support a percentage, but Google chooses eligible users at random. That is useful for broad risk reduction, but it is not the same as choosing ten named restaurants.

Managed Google Play: a closed test track is the cleanest documented mechanism for exposing a candidate version before production. Google supports assigning accessible track IDs through enterprise policy. Samsung also documents private-app track selection in its Knox Manage documentation; confirm the exact workflow in Haat's current console.

In-house APK: target candidate deployment deliberately. The reviewed Samsung documentation does not establish a universal “pin Production to old version while Pilot uses the replaced shared app record” guarantee. Prove isolation using one pilot device and one untouched production device before scaling.

Official documentation: Google: closed test tracks · Samsung: Managed Google Play app tracks · Samsung: in-house APK update/reassignment

First: stop expanding the audience. If using a Google Play staged rollout, Play Console supports halt and resume. If using planned Knox device/group waves, do not send the next wave.

This does not undo a build already installed. For a faulty Android build, the normal recovery is a fixed build with a higher versionCode, then deploy that forward-fix to affected devices. An offline device also cannot receive a new cloud-delivered fix until connectivity returns.

Do not use group deletion as a casual emergency control: Samsung says deleting a group unassigns associated apps/profiles/content. Treat “stop future rollout” and “remove an already installed app” as separate operations.

Official documentation: Google Play: halt/resume staged rollout · Android: versionCode · Samsung: group deletion/unassignment behavior

An offline tablet cannot download or complete a new cloud-delivered app update. For Managed Google Play High priority, Google explicitly says an offline device updates the next time it connects to the internet.

For a direct Knox in-house APK deployment, do not promise a completion time while the tablet is unreachable; confirm the device checks in and verify the installed version after connectivity returns. “Push now” is therefore not instant completion.

Official documentation: Google: managed app update behavior · Samsung: Last seen, app versions and install/update command

For app assignment, Samsung documents installation type, managed automatic update behavior, an optional scheduled installation start time for auto-installed apps, automatic launch after installation or after every update, managed configuration, and assignment to groups/organizations.

Changing these management settings is different from changing application code. If Haat Partner + itself needs new functionality, Engineering still ships a new build.

Official documentation: Samsung: assign apps · Samsung: edit app settings and push update

In device details, Samsung documents an INSTALLED APPS view with app version and an ASSIGNED APPS view with version, installation status and source. This is the Knox-side release evidence.

For Haat, complete the acceptance loop with the application's own evidence: correct restaurant/session, connectivity to Haat backend, and a test order. Knox can prove device/app state; it does not prove an order was accepted by Haat's backend.

Official documentation: Samsung: device and app details

Its new-console assignment guide contrasts an unscheduled installation with a scheduled start. It does not publish a per-device seconds-level completion promise. A scheduled start is not a completion deadline, either.

For Haat's pilot, record command sent, new version reported, app reopened and test order completed. Repeat with weak connectivity and with the app active. The actual results determine whether the direct route meets Haat's urgency requirement.

Official documentation: Assign apps - new console · Device information and app commands

An offline tablet cannot download the update. After it reconnects, check deployment status rather than assuming success. Insufficient storage, an incompatible package or mismatched signature needs remediation. Inspect the reported installed version and logs, then retry the intended assignment/action.

Dashboard Last seen is a management-contact timestamp, not a live promise that Haat is receiving orders.

Not as a normal lower-version overwrite. The ordinary recovery is a forward-fix with a higher versionCode. Example: stable 310 → faulty 311 → repaired 312. Reusing older code still needs testing against the current on-device database and data.

Uninstall/reinstall deletes app data and may require restaurant login again. It is a disruptive recovery procedure, not a seamless rollback. Direct Knox delivery does not remove Android's version/signing checks.

Official documentation: Android: versionCode and downgrade protection · Android: update and cross-store rules

No blanket guarantee. Google explicitly says an active app may be closed for a high-priority update. For routine changes use a tested maintenance policy; for an incident Haat must weigh interruption against leaving the fault running.

Saving order state, reconnecting and preventing duplicate actions are Haat app/backend responsibilities. Test the supported auto-run-after-update or kiosk relaunch behavior rather than assuming it restores a business session.

Official documentation: Google: update timing and interruptions · Internal app assignment - original console

No. App assignments and managed app-update settings govern Haat Partner +. Android system-update settings and optional Knox E-FOTA govern device firmware. Scheduling the first app installation is also different from choosing the policy for later app releases.

Official documentation: Samsung: Android Enterprise app-update settings · Assign apps - new console · Samsung: firmware management

Yes: make it inaccessible to the restaurant through the kiosk experience, while keeping the required Play delivery components working when using Managed Google Play. Restrict user installs, uninstalls, other sources and account changes as appropriate.

Do not blindly apply Samsung's Hide apps policy to core components: the documentation says it can uninstall an already-installed app. Hiding user access, disabling a package and removing a package are different operations.

Official documentation: Samsung: single-app kiosk and allowed utilities · Samsung: Android Enterprise restrictions

Knox Manage documents controls for user installation/uninstallation, app settings, allowed/blocked app use, camera, screenshots, USB and connectivity. Kiosk settings control Home/Recents, the notification/status bars, power-menu access and selected settings.

Apply the ones Haat actually needs. Keep a tested support path for Wi-Fi, sound and any printer. Essential background apps may need to remain allowed; test that the restriction does not break the managed APK update route.

Official documentation: Samsung: Android Enterprise restrictions · Samsung: single-app kiosk and allowed utilities

New console: Devices > select tablet > LIBRARY > Apps. Compare INSTALLED APPS with ASSIGNED APPS and their installation status. Device information adds battery, storage, OS and firmware; logs help diagnose actions.

Dashboard tiles summarize device states, issues, enrollment and assignments; reports can be customized. Location needs its collection policy/permissions. Some older network-usage counters are explicitly unavailable on Android 10+, so do not promise universal live traffic metrics.

Official documentation: Device information and app commands · Samsung: dashboard tiles · Samsung: custom reports

Knox Manage exposes supported device actions and can launch a Knox Remote Support session. Remote Support is a separate service with its own setup/entitlement and device permission or consent requirements; it is not universal unattended access.

Lock, reboot or wipe are management actions, not ways to correct a restaurant's Haat account. For a lost tablet, revoke Haat access as well; an offline device cannot execute a new remote wipe until reachable.

Official documentation: Samsung: device actions · Device information and app commands

No. Naming or grouping a tablet only organizes management. Future automation can send managed configuration to an app that implements it. Haat's backend must validate activation and issue the correct session. No password or reusable privileged secret should be treated as a safe plain configuration field.

The current APK's support is unconfirmed. A business identifier is a routing hint, not proof of authorization.

Official documentation: Android: implementing managed configurations

Yes, through another supported enrollment method such as QR setup, unless Haat restricts its environment to KME-only enrollment. But a tablet merely listed in KME is not yet a managed device. App delivery starts after successful management enrollment and assignment.
