I've owned Samsung S and Note phones for the better part of 4 years now and one thing I consistently find on every one of them is the terribly laggy startup no matter if you have a flagship or not. I used to have an iPhone 6 and it never once lagged on startup yet were in 2021 and Samsung still can't figure out how to make the startup of their phones smoother. It's really a bad look. You could do something like increase the time it takes for the phone to boot up so it can finish turning everything on and then allow users to enter their passcode or you could do some optimization to allow for a smooth startup but there should be no lag when I swipe up, or enter my password, or get to the home screen. It makes my $1000+ smartphone feel like a cheap $50 toy phone so please fix this by the full release of One UI 3.
