Hi Tommy,

Have you installed a new build of the app on the phone?

A new plugin is one of the situations when the user must install a new build to have it working (read in more detail here):

Kind Regards,

Hello João

Sure, I have been installed a new build of the app on the phone

but still not work

I tried to the creator's demo, it is work fine(even phone and browser)

Am I miss something?? Thanks

Hi tommy super

Did you test on the browser as well?

On my side, I tested on the browser and also on mobile and worked on it both. The problem with mobile is the camera is working is the front camera e, not the back.

Try to debug the app to see if you can get the problem.

Dear Goncalo,

Thank you for your reply,

I test on the browser, it just displays a red line

Is it my device problem??? Could you share the oml file?

I used your oml without any change.

You need to give permissions on the browser to use the camera.

Try to use the incognito mode.
