Shared Android Devices in Transportation: Sign-Out and Shift Handover Tests

What has to be true before the next person picks up the device?

This page gives a proposed shift-handover test for a shared Android device in transportation. A previous login can leave the next shift on the wrong stop, or with a task that never uploaded. Agree the six checks below on the exact model, build, app, and management platform before you treat sharing as acceptable. Vehicle mounts and barcode field rules stay on their own pages: fleet management devices and logistics scanner acceptance. Policy control on the device still has to be confirmed for that OEM and management stack, as described on managed and controlled Android devices.

Which six checks belong on the shift handover sheet?

Use one row per check. Write the expected behavior before the test, then leave the observation empty until someone runs it on the sample. Passing one row does not pass the sheet. A returned or wiped device is a different event: use Android device deprovisioning and handover when the unit is leaving management, not when the next shift is about to use it.

What does a participating-app sign-out actually clear?

Microsoft's Shared device mode for Android devices page, last updated 2025-05-23 and read for this guide on 2026-10-11, describes one model for apps that support that mode. In that description, a worker signs in once and gets single sign-on to supported apps. On sign-out, the worker is signed out of the device and of those supported applications. The same page says the sign-out call removes the signed-in account and cached tokens from the app and from the device, and that it does not clear the application's own data. The app has to clear its data and anything it is still showing. It also says the developer has to detect a user change, including when the app returns from the background, and clear the previous user's data. Multiple-account apps are outside that mode. Use this as the boundary of that document. It is not a statement that every transportation app on the handset cleared its cache, and it is not a Vantora test result.

• List the apps that participate in the shared sign-in, and list the apps that do not.
• After sign-out, open each participating app and record whether a previous screen, name, or task is still visible.
• Open each non-participating app the shift actually uses and record its session separately.
• Bring the app back from the background and record whether the previous user's data returns.
• If sign-out fails, keep the device with the previous shift until the agreed exception path is done.

Where should an unsynced transportation task go?

Decide the task rule with the app owner before the sample, using a non-sensitive test job. Three dispositions are enough: the task uploads and the handoff waits for that result, the task stays assigned to the previous person and the next person does not see it, or the handoff stops until a dispatcher clears it. Write which of those three the app supports. If the app has no hold state, do not invent one in the test sheet. The transportation and logistics device scope is the place for the route and proof workflow around that task. This page only asks whether the task is safe to leave on a shared handset.

What do you record when sign-out has no network?

Run one attempt with the radios off or the test network unavailable, in a safe non-production job. Record the message the previous person sees, whether the account is still present, and whether the device can be given to the next person. Microsoft's cited page describes sign-out for supported apps on a device already in that mode. It does not describe a successful offline sign-out for every management stack. If your app cannot complete sign-out offline, the sheet should say the handoff waits, not that the row passed. Depot Wi-Fi on the day of the test is not a substitute for this row.

How do you know the next employee has their own work?

The next person signs in on the same device and the same build, then opens the shift's real task type with a second non-sensitive test job. Record the account name on screen, the first task list, and any photo, signature, or map state left from the previous job. A login that lands in the previous person's unfinished list fails the row. Identity, EMM enrollment, and app distribution stay subject to validation on that device and stack. This check does not choose the scanner input path and does not certify the handset.

What travels with the device besides the login?

The next shift needs the unit, a way to charge it, and the asset identity. Record the cradle or cable that was in the brief, whether the device shows charging, and whether the asset label matches the unit in the handoff note. Stop there. Dock geometry, ignition power, and vehicle fit are selected on rugged tablets or the fleet page, not on this sheet. A device that charges on the depot bench can still be the wrong mount for a cab. That is a different acceptance row.

When this does not apply

Skip this sheet when each person has their own assigned device for the whole shift, and use it when the same Android unit is handed to the next person. It does not select a vehicle dock, accept a barcode field, interpret driving rules, or claim a certification. It also does not turn a sign-out of participating apps into proof that every app on the device deleted its data. A factory wipe or a device leaving the fleet belongs on the deprovisioning guide.

What to send us

Send us the project brief with the model, build, apps, management platform, and the non-sensitive conditions from the rows above. We reply within 1 business day. Use the project brief. The review says which of these rows can be run on a sample, and which inputs are still missing.

Method and sources

The sheet is a proposed method. Observation cells are empty on purpose. Microsoft's Shared device mode for Android devices page, last updated 2025-05-23, supports the participating-app boundary and the statement that sign-out removes the account and cached tokens without clearing the application's own data. The fetch used here was saved on 2026-10-11. It does not support a claim that every app on a transportation handset was cleared, and it does not set a Vantora battery, price, or certification figure. Device and management behavior on a Vantora project remains subject to validation on the chosen model, OEM, and management stack. Updated October 2026.
