Proximity sensor on S10lite samsung

[S102]

My husband bought new phone S10lite Samsung two weeks ago. Yesterday we saw a blinking light on screen while making a call. I checked on net this is proximity sensor but my husband told me when I buy this and made a call I didn't notice this blinking light on screen. He is thinking there is some issue with the phone. Can you please help me out? Is there any issue with the screen or it's a default feature?
