PowerApps in Android Kiosk Mode Stops Syncing with SharePoint After Random Time – Need Help!

Hi everyone,

I'm struggling with a problem in my room reservation display solution. I'm using an Android tablet managed via Intune, running in Kiosk mode (single-app) with a PowerApps application as the only visible app.

The app queries a SharePoint list to display the current and upcoming events for a meeting room. It also allows users to create quick "local reservations" (patching a new record into the list).
Everything works perfectly on the web browser or PC, even for 24/7 use.

The issue only appears on Android tablets:

After a few hours (usually once per day), the app appears to "freeze" – it no longer updates data from SharePoint (refresh doesn’t work).
Buttons still respond, UI is "live", but no data gets sent or received.
It cannot be exited due to Kiosk mode – only way to recover is a forced reboot from Intune or physical restart.
PowerApps Monitor shows no clear errors, and the app works fine after a reboot – until it happens again.

What I tried:

Minimal Refresh calls (only one Refresh('MySPList') in a timer every minute),
Data filtering is done client-side using Now() to check time-based conditions,
Patch statements are standard and work in all environments except in this "frozen" state.

My guess:

It could be a token/session expiration issue in Kiosk mode, and the app can’t re-authenticate properly in background?

Has anyone solved this, or knows how to:

Force reauthentication in PowerApps in Kiosk mode?
Detect when token/session expires?
Avoid this issue altogether?

@CU16050845-0 Hi,

Sounds like the token expired, and it doesn't tell the end user to re-auth...

I think the easy way is schedule reboot task in Intune.

Thanks for the suggestion @stampcoin!

I already tried scheduling a daily reboot via Intune – the device restarts every night. Unfortunately, the issue still occurs randomly during the day. Sometimes the app freezes just an hour after reboot, other times it lasts over 10 hours without problems.

So far, I haven’t found any clear pattern or trigger.

I also checked Entra ID sign-in and audit logs for the device account, but I didn’t find any failed authentications or unusual activity around the time the issue occurs.

It feels like a silent token/session expiration that PowerApps doesn’t recover from while running in Kiosk Mode – and since the user can’t re-authenticate, the app just stops syncing.

I’d really like to avoid relying on reboots as a workaround – I need to find the root cause of why this happens and how to make the app reliably reconnect or recover.

@CU16050845-0 Hi,

If the reboot doesn't help much,

Use a timer to call a trivial SharePoint query every few minutes.
If the call fails (use IfError or If(IsError(...))), display a “Session expired – please reboot device” message.
Not automatic recovery, but at least clear visual feedback.

Hi,

I was curious if you found a solution to this? I am facing the same issues. A reboot is a workaround but is not ideal.

We have a samsung tablet and testing out the PIN App option to see if that works better than Intune and Kiosk mode.
