Hi! Assuming you mean within the Google Gmail app, I'd suggest reaching out to them—being that my unread emails are still bold. Assuming this means yours are being marked as read automatically
Hi Having same issue. Really frustrating. New emails in gmail no longer bold enough on phone to distinguish between read and unread. This is purely a phone issue not a google issue because there is no change on computer. Dark mode helps to identify which are unread but do not like using dark mode. Hope Samsung find a fix soon
