There are some video clips online purporting to be OneUI 7 in usage... they are **bleep**. Unfortunately, I do not have the clips myself... but they contain the images below...
Still very Samsung style... App icons seem to be updated on the per app basis. In which case, even OneUI 6 will receive new app icons.@chunvn8888 for the screenshots...OneUI 7 app drawerOneUI 7 HomeOneUI 7 Lockscreen with charging info
For those that claim OneUI 7 is copying iOS 18... Please, try to be realistic for once... Just review iOS 18 and see how much Android it is. From changing icons on the lock screen, free icon placement on the desktop, scheduled messages, colour palett...
I'm much happier to have been of help to you... the other solution is: while in a video call with someone, swipe down the notification panel. You will see the video call effects there, tap on it, and then select background, and select none.
Alright... Two last solutions. First, try to go the Video call effects app and tap on storage, and then clear data... tap delete to confirm. Let me know if it works.
