Yellow tinge on Selfies with flash on Iphone 11 pro

Hi,

I have just bought an i phone pro and the issue i am facing is that when I take selfies with the front camera and use the selfie flash under low light, the photos have a yellowish/greenish colouration/tinge on one edge of it.. This only appears when the front flash is on. Incase I take a selfie without the front flash the selfies are absolutely normal. A photo of this defect is also attached
