Agreed, unfortunately there us an issue with some handsets, including mine that was hot to touch at first, and this forum is being used to complain about samsung, rather than asking for advice, and reassurance which is different. Overall I'm not convinced there is a wide problem with half million of handsets sold. we're not one of the lucky ones to get a gooden, but there are those that have been unlucky. My S21U is amazing and since the update no problems, great battery and performance.
