How to use NFC and Camera at the same time

Each Service(NFC, Camera) work well seperatly

But if i use both on same activity NFC reader is not work (is it software problem? or hardware problem?)

nfc reader polling is automatically disabled when camera opened

This is my app log this log ocurred when i switch activity (activity with camera → activity without camera)

I  isNFCAllowed is called for userId - 0
 D  NFC checking for 0
 W   container manager null for 0
 I  allow NFC for 0

So how did this go Ahsan and reeeeeoy?

This post was the only thing I could find about the issue other than that it might be a hardware limitation on some devices.

I face similar issue on a Galaxy S24 Ultra.
When I have a camera view open the NFC can’t be read.
