PWA has access to sensors when they are dissabled for browser

kalwadi

on usage page it states that PWA should inherit sensors pretermission from browser they use.. but with Vanadium and Brave PWA (ProtonMail) was able to access sensors (accelerometer) and act accordingly by rotating screen, I have screen rotation disabled.

Are there any additional settings I missed to fully disable sensor access for browser?

Have you turned off the Sensor permission for Vanadium?

Long press Vanadium icon > App info > Permissions > Sensors

kalwadi Brave does not even allow sites to access sensors on any device regardless of sensors permission.

I have no idea why this might happen, but I was able to reproduce this issue successfully. Really strange.

kalwadi

Yes, sensor permissions are disabled

Do you know if it is actually accessing the full sensor data, or just the screen orientation?

kalwadi

roamer4223 I don't know and have no idea how should I test it.
The issue only appears when using PWA. if I access the side within browser the screen does not rotate.

[deleted] this does not support being added as PWA so I can't use it to test.

kalwadi I'm sure there is a simple way to test it. I have no ideas though. If I think of anything I will post here and try it. I have noticed the same thing before though and wondered about it.

Just noticed this happening in my Proton PWA.

Did anyone find out why it has permission to know my devices orientation and if there's a way to deny that permission?

How did you notice this happening?

randomname well that explains it then I guess

idk about this specific case with pwa but screen orientation portrait/landscape is different from sensors access, an app with sensors disabled is still being told by the OS when the phone is in portrait or landscape position even when auto-rotation is off system-wide, it is the usual behavior
