Android delay with camera


I’m building an app that needs to scan use the camera to scan QR codes. The little icon to search using the camera is there, but I sometime need to wait 5-10 secondes before the camera is activated (the camera opens on a black screen, then the image appear and the scan works).

It’s a new phone (Galaxy note 20).

Anybody had this issue before?

Still no solution to that problem?

Brand new android note 20. First time I scan a qr code is fine. After that I get a black screen for sometime 30 seconds before the camera starts working again.

Only in appsheet.

May be best to contact to get someone to look into this. I don’ recall other posts about this issue, so I suspect it’s not common.
