In my samsung galaxy m52 5g, when ever I check it through airtel app it shows that handset doesn't support 5g, first it shows like hardware compatible but software needs to be updated but now it shows like handset itself not a 5g
It's because of screenguard bro... if u want to check remove screen guard and then u will get picture without circleIn my device also I faced this issue earlier
It's not a bug bro. It's a feature called floating shutter button, u can turn it offCamera > setting > shooting methods > floating shutter button.
