Actually we haven't received any more complaints about the recent/open apps and the apps menu.
Therefore, this change seems to be based on user preferences. Everyone may like something else, so to be able to send this suggestion to our team of developers we would need more people to be interested in this change and want to have this change implemented in their devices. When more people confirm being interested in this suggestion, I can send it to Korea. Let's say we need about 20 likes. Thank you in advance for your understanding!😉
what was wrong with keeping it as it was?
let me guess users preference, instead of having a choice let's make it grey, sure people will love it, while you are at it get rid of colors from the phone, make it monochromatic again, I'm sure people will love it and pay same price for the phone.
what planet are you on?
First of all check other posts and you will see everyone else is complaining. This is not an individual user's own preference, it's you Samsung's preference forcing on customers. Bring back at least the solid black background for the app drawer. Many like us would have not updated at all if this was known beforehand.
I think there should be option to keep the notifications like in one ui 2.5, i never disliked them. Personally, i prefer that contrast look more than this blur effect
