Lenovo Android kiosk goes to sleep and does not relaunch after rebootSolved

I’m setting up Lenovo TB311FU tablets as sealed, wall-mounted Android Enterprise Device Owner kiosks. They are locked to a single web app, so they need to recover without anyone touching the device.
The kiosk generally survives an unattended reboot, but after changing some peripheral/day-night settings, the tablet started going into sleep mode. When I reboot it, the device does not reliably load back into kiosk mode.
I also noticed that a scheduled day/night change did not apply at first, but later found the tablet was offline. Once Wi-Fi came back, the day mode applied.
What should I configure in Hexnode so the tablet does not sleep and the kiosk app launches automatically after every reboot?

For an unattended Android kiosk, configure both the screen timeout and kiosk launcher behavior in the active policy.

1. Go to Policies > <policy> > Android > Restrictions > Basic Restrictions.

2. Set Screen timeout to Never.

3. Go to Kiosk Lockdown > Launcher.

4. Add the web app or kiosk app that should open on the device.

5. Set App auto-launch delay to 1 second.

6. Save the policy and push it to the Lenovo device.

This prevents the tablet from entering sleep mode and ensures the kiosk app is relaunched shortly after the device reboots.

For scheduled day/night changes, the device must be online when the policy or automation is applied. If Wi-Fi is off or the device is offline, the change may apply only after connectivity is restored.
