1)6.4inch compact ultra varient phone with all the bells and whistles .it's ok if it doesn't have spen . It should be same build quality and material, like pixel 9 pro and iphone 16 pro
2)good haptic motor for ultra variant,My s24ultra has mediocre haptic comparing pixel phones and Chinese phones. Integrate haptic feedback whole ui
3)Ultra fluid and consistant animation , now even Chinese phone have much better animation than oneui
4)Better battery life , now even pixel 9 pro xl can beat s24ultra battery life
5) Better charging speed . 45w charging was fast 4 years ago ,now it's mediocre speed
6)upgraded camera , Samsung should improve its image processing to accurate and fast . I can't accept over saturated oil painting for 1300dollar
