- Device model used: X23
- Operating system version and last update: VollaOS16 (android 16) 14 juli en security update juli 2026.
- Affected app including version number Camera version 1.1..60032 (com.mediatek.camera)
- Attempts already made to solve the problem: several.
When I make a picture I can tap the lower left corner. I see picture and can tap share.
Then I can choose wich app I want to use to share.
I choose Proton Drive, the contents of my cloud disk show up. I can choose a map and I can see the contents of the map.
As soon as I press the Upload button in the Camera app, nothing happens. However the cancel button I can activate.
I also noticed that I can upload files if I use the Proton drive app directly. So it's not a malfunction in the connection.
I did a search with AI (Lumo) and it suggested it was a possible problem with ContentResolver.openInputStream() call or equivivalent SAF callback, which likely fails when handling URI's passed from external apps via Share Intent under micrG. This can result in a likely "dead" UI state on teh " Upload" button.
I consulted the Proton helpdesk, they tried to assist, even send me a Beta version of their app. Nothing worked.
In the end they suggested it was a possible security problem with tapjacking. (They kindly noted that I may be encountering this behavior because of a recent security update on Android. You can find more information about it here:
https://developer.android.com/privacy-a ... tapjacking
I tried to solve this by by disabling unnecessary accessibility services that could potentially be exploited for clickjacking attacks.
Go to Settings → Accessibility
Click on Installed apps or Services
Turn off everything that is not an essential accessibility tool
Test whether the tapjacking issue disappears
No result.
This afternoon I noticed I couldn't activate a play button for a podcast as well.

I can activate the share button, disable and enable volume button, I can alter the play speed button. I can't activate the PLAY button. I tried with an android device, wich worked perfelctly well. I tried on a Ubuntu PC with firefox and it works there as well.
It doesn't work on my Vollaphone 23X
I conclude that the problem is issued by something in the SW, or some configuration of the phone.
I look forward to a reply for a solution.
Kind regards,
Eric
Update 8-16-2026:
Today it turned out: the podcast button works: https://www.consumentenbond.nl/acties-c ... ne-privacy
I didn't do anything special to get this problem resolved. However. The other problem not able to upload files to my Protondrive still excists. The upload button can't still be activated as reported earlier in this issue. Note: I also tried with flushing cache from both Protondrive app as well as document browser, which is version 16, com.android.documentsui.
Another problem I faced earlier: Sometimes when installing an app from Aurora store I got a message that the app is not suitable for this device. After flushing Cash memory and reboot the device, such an app will install and works flawlesssly. Probably the problem not being able to activate the upload button (or a play button) is related.
Does anyone have a clue?
