I just got my OnePlus 15 back from a co-worker who was testing the phone, and after setting it up, I was horrified by the new Recents multitasking UI. Not only was it a blatant iOS ripoff, but it was a worse design than what OnePlus has employed for years. I wanted the old look back, but I couldn't find it anywhere in the settings menu, even after searching for everything I thought it might be called.
Turns out, the option to change it back to the "flat" look is still there, but it's hidden for some absolutely bizarre reason. Most companies adopted the stacked tile look for Recents last year, a design that's a massive improvement over the garbage stock Android Recents UI, but one that's far worse than OnePlus's design, which I've long called the best multitasking UI on any phone.
