Android Camera App that Doesn't Shutdown Automatically

[Subtitles]

I have a Samsung Galaxy mobile phone. It has the default Camera App, but it just shuts down after a short while.
I need a different App to take images but I want it to stay ON until I close it. Tried different Apps but they all shut down after a short while.
If you know of such an App, then please give details. A paid App will be considered.
Thanks.

Have you tried giving the app unrestricted battery access ? Samsung is especially aggressive when it comes to maximising battery usage and will
close/suspend apps whenever it can
