Samsung s9 android Pie Update Problems

i've recently updated my S9 to android pie + one UI

1.when i swipe up (new navigation bar) to recent apps, in horizontal view it always...go in to recent apps tab view -> wait awhile then switch to vertical view..which is very delaying + slowing down the movement and annoying...like when im at a full view horizontal game and i decided to go to recent apps view i swipe up to recent apps, it goes from horizontal view to vertical view not instantly but delay and turn.

2. recent apps button after u swipe up or click, it always go to the recent apps view but in a second it will move to the last apps i used which i only wanted to see the recent apps not samsung helping me to 1.go recent apps 2.move to the last apps used (please note it does nt go into the apps just showing the last used apps view in recent apps tab view) 3.i need to swipe my screeen left to move back to the apps im using to close it..very annoying

3.the fingerprint reader reaction got slowed down, the whole ui got slowed down..

Thanks in advance!
