I think they would try some cool new live focus effects from S11 ( or S20 as IceUniverse has stated today) onwards which will make their way in the budget phones and flagships in future . maybe these 2 effects were something similar to those new effe...

No probably it is trying to tell this update would remove the portrait dolly and portrait backdrop effect only...Other live focus effects like Blur..spin...zoom..color pop would be present.. more over these effects r only present in mid budget phones...

plus have u seen one more thing ?.. Samsung has removed that cool motion effect from home screen wallpaper?

I too...in android pie the noise was relatively lower ... in fact the camera captures at same ISO and same shutter.....but the processing has become something wrong so producing more noise.

can u confirm if gear 360 app is working on android 10 ?
