I think beta 4 is the last before official release so nothing more new is gonna come. Just more bug fixes. Overall this update I'd give it a 6 out of 10 excepted more if a visual overhaul, not to crazy either about material you.
Any wishlist for One UI 5?
Yeah honestly I'm kind of disappointed I expected more of a visual aspect of it kind like what Pixel did.... to me they could of just done the stuff they did in a regular software update.... to me it's just nothing that special to be one ui 4 you know
