Is it just Samsung Internet that is in Italian or is your entire device also in Italian?
As far as I'm aware (will happily be corrected) your language would be set at device level.
Is it just the homepage in Italian! Can you try other pages such as
www.tesco.com and what language are they in?
I am not employed by Samsung nor do I receive any remuneration as a Samsung Members Star.
My device is an S25 Ultra.
