From what I have seen in Samsung's phones, especially the mid and the budget range, they could make the lock screen animations much nicer and smoother, like when you press the power button there could be a nice and brief animation that kind of welcomes you to the device. Small thing, but can make a great difference. Similarly when the AOD is on and the the power button is pressed, there again could be a brief animation, which I have noticed on the top end phones could trickle down a bit to the lower ranges of the phones, especially the top range of the budget phones like the A51 and A71, if that makes sense!
