Phone PIN visible to keen observers? I acquired a S8+ earlier this week. One thing I noticed is when I enter my PIN, the number will only vanish after I hit the next number in the sequence. At best, a keen observer will only see the last number. At worst, someone will get my PIN by watching over my shoulder, etc..

Is there a fix for this behavior on the phone?
As pointed out by @user452820, there is a security setting in settings for that.  Go to Settings > Lock screen and security > Other security settings and change the slider on Make passwords visible.



The blue slider should be greyed out to stop it.
