Well, Scamsung u did it to me this time.

Sure the whole UI has changed, and improved design-wise... BUT THE LAGGING. SO MUCH LAG. This is no better than my first phone–Galaxy S5 in 2024. Comparing it to my phone toda–A15–it's so much faster, idk why. There are zero animations in the basic stuff, 5s for the Quick Panel to drop down, and pull back up, the fingerprint is messed up (I havent changed it since One UI 8), camera app crashes, and the most annoying of them all: Volume. The buttons work, but the actual volume seemed to have dropped by half...HALF! Tried disabling the custom EQ, no luck, every single time something plays it switches back to Balance, and I've experience 2 latency with the audio-playback sync thingie. The only thing i had a problem w/ One UI 8 was my calls on Phone, but it's like that's the only thing that was fixed after the update. Thank u samsung.
