Android kiosk mode blocks gallery image upload in web formSolved

Hello @timo-liam ,

This usually happens when the Android file picker, gallery app, or a manufacturer-specific package required for media selection is restricted by kiosk lockdown.

In Android Enterprise kiosk mode, the visible kiosk app may be allowed, but the upload workflow can still depend on background system components such as the Photos/Gallery app, document picker, chooser activity, or OEM-specific media packages.

Try the following:

1. Go to Manage > Devices and open the affected Android device.
2. Open the Applications sub-tab.
3. Check Blocked packages after reproducing the upload issue.
4. Note any Gallery, Photos, document picker, chooser, or media-related packages that appear there.
5. Edit the applied kiosk policy and go to Kiosk Lockdown > Android Kiosk Lockdown > Background Apps.
6. Add the required blocked package IDs as background apps.
7. If the Gallery/Photos app itself is needed, add its package ID to the multi-app kiosk configuration as well.
8. Save the policy and allow it to sync to the device.

For Samsung tablets, the required package may differ from stock Android devices. If you use different manufacturers, identify the Gallery/Photos package separately for each model.

I checked the blocked packages section and saw a few chooser/gallery-related packages after trying the upload again. I added them as background apps, but the Photos app still seemed to close immediately when launched from the upload button. The devices are Samsung tablets.

On Samsung devices, adding only the browser or web app to kiosk is often not enough. The Samsung Gallery/Photos package also needs to be part of the allowed kiosk flow.

What worked in a similar setup was:

• Add the Samsung Gallery/Photos app package to the multi-app kiosk list.
• Add the same Gallery/Photos package under Background Apps.
• Add all blocked chooser/document/media-related packages shown for the device under Background Apps.
• If using a browser or website kiosk, confirm that image/file upload is allowed for that app.

After applying the policy, scan the device and test the form upload again. The upload picker should stay open and allow the user to select a photo or video.

It worked. I have one more thing to ask, users also needed to move between the browser/form and the gallery more easily inside kiosk mode. How can I do that?

To enable seamless switching between open applications in Android kiosk mode, configure the Recent apps button within the kiosk policy. This eliminates the need for users to repeatedly reopen apps or browsers from the home screen.
